Hybrid warfare-The Naval Dimension

(Published IndraStra Global 01 Jan 2017,

 It is so damn complex. If you ever think you have the solution to this, you’re wrong, and you’re dangerous. You have to keep listening and thinking and being critical and self-critical.

Colonel H.R. McMaster, 2006

In his monograph, Strategic Implications of Hybrid War: A Theory of Victory[1],Lieutenant Colonel Daniel Lasica posits that hybrid force actors attempt to combine internal tactical success and information effects regarding enemy mistakes through the deliberate exploitation of the cognitive and moral domains. In this manner, he describes hybrid warfare simultaneously as a strategy and a tactic because of the blending of conventional, unconventional, criminal, cyber and terrorist means & methods. A hybrid force is thus able to compress the levels of war and thereby accelerate tempo at both the strategic and tactical levels in a method faster than a more conventional actor is able to do. In this theoretical model, the hybrid actor will always gain a perceived strategic advantage over the conventional actor regardless of tactical results. David Sadowski and Jeff Becker, in their article “Beyond the “Hybrid Threat: Asserting the Essential Unity of Warfare,[2]” assert, that the idea of simply seeing hybrid warfare as a combination of threat categories or capabilities fails to appreciate the complexity of the hybrid approach to warfare. Rather, they argue that the essential aspect of hybrid warfare is the underlying unity of cognitive and material approaches in generating effects. Such a unity of cognitive and material domains allows for flexibility in a strategic context in which social “rules” can be redefined in an iterative process to the hybrid’s advantage in terms of legality and military norms.

Majors Mculloh and  Johnson in their monograph ‘Hybrid warfare’[3] have said that hybrid war may be best summarized as a form of warfare in which one of the combatants bases its optimized force structure on the combination of all available resources—both conventional and unconventional—in a unique cultural context to produce specific, synergistic effects against a conventionally-based opponent.

 Don’t ever forget what you’re built to do. We are built to solve military problems with violence.

– A Former Brigade Commander in Op Iraqi Freedom

Therefore, it will not be wrong to say that Hybrid warfare in naval context is a violent conflict utilizing a complex and adaptive organization of regular and irregular forces, means, and behavior across a predominantly maritime domain among others to achieve a synergistic effect, which seeks to exhaust a superior military force.

Alternatively, put simply, it is naval irregular warfare plus cyber war and any other component that emerges in future. CIA has succinctly brought out the contrasting dimensions of Modern versus Irregular warfare in the following table:

Contrasting Dimensions of War[4]
Modern Irregular
Organized Informal
Advanced technology At-hand technology
Logistics-dependent Logistics-independent
National direction Local direction
Coherent doctrine Ad hoc doctrine
Decisive battle Raids and skirmishes
Soldier Warrior
Allies Accomplices
Segregation Integration

Littoral areas and cities in vicinity of the coast could be important sites of future conflict, and both have characteristics that make them more complex than the high seas, and hinterland. Adversaries will increasingly exploit these complex environments to degrade technological advantages of regular forces. Given the close proximity of many cities to the coast as well as abundance of unmanned coastal areas, maritime hybrid is a distinct possibility requiring active involvement of the Navy and the Coast guard. In case of a maritime hybrid war the normal components of the Navy would continue to play an important part in the littorals and in open seas for interdiction of adversary’s irregular assets like floating armories and mercenary flotillas.

Maritime forces are often utilized primarily in support of ground operations, but it is seen that; in environments with a maritime component; maritime operations tend to have a noticeable comparative advantage over land-based operations in terms of mobility, freedom of maneuver, and the ability to impose a smaller or less visible footprint on land. The maritime forces could easily choke supplies through the sea route to reach adversary, protect own maritime trade and fishing in the area, provide logistic and fire support to forces on land from the sea, close escape routes and so on. One important point is that vital external maritime support can be conveniently obtained from friendly nations at sea for ISR, communications and fighting cyber war. The supporting ships could be operating as close as just 12 miles off the coast or hundreds of mile in open seas without violating any regulations.

Now it would be appropriate to look at a few of the salient features of 26 Nov 2008 Mumbai attack as relevant to subject at hand. The Mumbai attack has been analyzed in great depth by various agencies (for e.g. Rand’s ‘Characterizing and Exploring the Implications of Maritime Irregular Warfare’[5] and ‘The Lessons of Mumbai[6]’) and individuals, therefore an attempt is being made here to highlight the main findings of some of these studies. In addition to the meticulous planning, reconnaissance, likely pre-positioning of weapons & ammunition, the major innovation on the part of the terrorists was the real-time exploitation of the international media. Each of the terrorists carried a BlackBerry smart phone to monitor CNN and BBC Internet coverage of the attack in real time. They then immediately adjusted their tactics to increase the amount of media coverage that the attacks would receive. It is believed that the major efforts made by the terrorists to kill U.S. and British civilians were part of the plan to garner more international press coverage.

The case of the LeT attacks in Mumbai illustrates the advantages that could accrue to an adversary from a maritime approach to a target. A maritime approach allows operatives to avoid border crossings and airport security, it offers opportunities to hijack a local vessel so that attackers can blend in with the normal local coastal traffic, and offers terrorist teams extra time for pre-attack planning as well as extra time for rest just before the attack commences. Finally, a maritime insertion allows terrorists to select very precise landing sites and infiltration routes.

The case of the LeT attacks in Mumbai also illustrates the disadvantages that can accrue to a terrorist enemy from a maritime approach to a target. First, once a full blown, large-scale assault has started, it can be very difficult to extricate the operatives. Second, the transport of large explosives aboard fishing vessels and trawlers is risky; thus, maritime terrorist strikes might be limited to relying on small arms to do their damage. Third, some kind of reconnaissance cell would have to be sent to the target city well in advance of the attack, providing an opportunity for a skilled intelligence agency to mount surveillance on the reconnaissance cell and break up the plot before the assault team could embark. Moreover, a maritime approach does not allow the terrorist team to disperse until it lands ashore. Even if the operatives approach in two or three different small boats, the interception of just one of the boats could drastically reduce the team’s numbers and effectiveness.

The fact remains that despite low technological instrumentation, a non state/state sponsored actor coming from open sea, could carry out effective surveillance & reconnaissance regarding the characteristics of targets at land/sea that could be attacked in future. Maritime Hybrid War may graduate to pose bigger economic threat than a military one. Furthermore, these economic costs could be imposed with relatively minor investments from the adversary.

What is worrisome is that now the Hybrid threat can emerge from anywhere in the vast oceans; be it floating armories, mercenary flotillas, or innocuous vessels carrying legitimate cargo with an embedded cyber war-waging cell. The maritime hybrid threat has to be interdicted using Naval and marine assets preferably before it reaches the shores and synergizes with other elements into a full-scale hybrid war. Even though the Indian Government has strived to put in place a very robust MDA there are intelligence gaps, which remain among the various agencies involved which could lead to slipping in of threatening elements physically or otherwise.

“The categories of warfare are blurring and do not fit into neat, tidy boxes. We can expect to see more tools and tactics of destruction — from the sophisticated to the simple — being employed simultaneously in hybrid and more complex forms of warfare.”

Professor Colin Gray

Cyber War

A word about the maritime dimension of cyber war would be proper at this stage. In recent years, there has been considerable discussion of the phenomenon of cyber warfare, its methods, and its ramifications. In essence there are three objectives that can be achieved by cyber-offensive activities: espionage (infiltrating the target’s information storage systems and stealing information), denial of service attacks (preventing Internet usage), and sabotage (infiltrating systems reliant on Internet connections and causing functional damage via malevolent programs). The media largely focuses on the use of computer programs as weapons in the cyber domain, but an attack on Internet infrastructure especially the submarine optical fiber cables is no less an option for terrorists, and often more devastating and effective. In fact, thousands of miles of more than 200 international submarine cable systems carry an estimated 99% of all the world’s trans-oceanic internet and data traffic. Widespread disruption to undersea communications networks could sabotage in excess of $10 trillion in daily international financial transactions, as stated by Michael Sechrist in a 2012 paper ‘New Threats, Old Technology Vulnerabilities in Undersea Communications Cable Network Management Systems[7]’ published by the Harvard Kennedy School. It is pertinent to note that satellites carry just about 5% of global communication traffic.

Even partial damage has extensive consequences because of the resultant jamming of traffic on the limited remaining connection. It is true that the diplomatic and military effects of having Internet communication with world at-large cut off would not be significant, but the direct and indirect economic consequences could be extremely expensive to our economy, especially with the transfer of much data to online cloud services that are actually placed abroad.

What bigger Hybrid threat can be posed at sea than the cutting off the subsea internet cables at time, place, and depths of one’s choosing or cutting off undersea facilities like VLF communication nodes and hydrophones? Would it not be an example of extreme denial of service weapon? Incidentally, such capabilities do exist with some nations today.

Two other aspects of hybrid war, which merit immediate attention of the maritime forces, are onslaught of sensors and swarm warfare.


One very important aspect of the Hybrid warfare is transparency in every field because f utilization of various types of sensors. This ubiquitous sensing revolution promises enhanced awareness of physical, social, and cyber environments by combining three technological trends: the proliferation of ever cheaper and more capable sensors into virtually every device and context; large data aggregation and ready access to it using vast cloud-based archives; and cross-spectral data fusion & sense-making algorithms running on increasingly powerful processors. All of these trends are accelerating, at exponential rates. For instance, as brought by Capt John Litherland, USN (ret), in his paper ‘Fighting in the Open: The Impact of Ubiquitous Sensors on the Future Maritime Battle space’[8]:

-The worldwide total number of sensors has increased tremendously and will pass the one trillion mark, or more than 100 sensors for every person on earth.

– Mass production of electronics has led to significant enhancements in Sensing capabilities. Every smart phone today has a complete inertial, electronic and satellite navigation system comprising just a minor component of its price. Incidentally, a smart phone today hosts of many  of the sensors such as, accelerometer, temperature, gravity, gyroscope, light, linear acceleration, magnetic field, orientation, pressure, proximity, relative humidity, rotation vector and temperature[9].

-The worldwide digital data generation rate now exceeds one ZB (1021 bytes) per year and global storage exceeds 10 ZB.

-The ability to fuse and make sense of unstructured data from disparate sensors and incommensurable formats is being addressed by use of advances in processing capability and data handling algorithms.

-The advent of sensors has however, made the battle space transparent. Today, the warfare has to adapt to this transparency and let go traditional concepts of concealment and camouflage. Stealth technologies are unable to cope up with concealing signatures of the multitude of sensors being used across various domains, be it in the air, on the surface or under water. Navies today can no longer spring a surprise on the adversary because it is not feasible to operate blind in a battlefield littered with multi-spectral sensors, dispersed spatially, and operating in broadband.

The Indian Navy (IN) has to prepare for this aspect of hybrid warfare. The Indian Navy could utilize some of the concepts out lined by Litherland in his paper quoted above[10] :

– Dispersal – IN forces must disperse over as much of the maritime battle space as possible.

– Deception – IN must strategize on targeting the adversary’s sensor complex across multiple spectra with noise, false targets, and cyber attacks.

– Range – IN must gainfully implement Net Work Centric warfare to bestow ‘crippling effects’ at large distances when dispersed.

– Speed – together with range, the speed at which kinetic and non-kinetic effects can be imposed on the adversary will also be a critical factor in Naval war.

Unless the Indian Navy starts preparing now to fight in the Age of Sensors, it risks becoming vulnerable in the event of a hybrid war.


Seminal work has been done on Swarm warfare by Prof. John Arquilla  and David Ronfeldt in their various writings (Swarming and Future of Conflict[11], Countering and exploiting Swarms[12], etc.) the present section derives from their thought processes. Swarm warfare has become the dominant doctrinal concept of certain navies like the Iranian Revolutionary Guard Corps Navy, which has about fifty missile and torpedo boats, along with other light coastal craft, all of which train to employ ‘ESBA’ i.e. like a swarm of bees tactics. The IRGC Navy also has several bases on small islands in the Persian Gulf, from which they can “swarm by fire” with the Chinese missiles in their inventory. China’s PLA Navy regularly practices swarm tactics with its missile, torpedo, and gunboats.

For the Indian Navy, comprised as it is of a number of high-value vessels, swarms pose a considerable and rising threat. Swarm attacks are likely not only from small boats, but also from aircraft, submarines, and drones. At present, the author is unaware of any fitting response by the Indian Navy focused on the use of counter-swarms of drones, and robots. The Indian Navy should also consider responses; as suggested by Prof  Prof. John Arquilla[13];  by designing swarms of much smaller craft like large numbers of jet-ski-sized drones or autonomous weapons whose goal would be to seek out and destroy incoming swarms with rockets, or by ramming and self-detonating. Small and swift Weapons could pose a far superior swarming threat to hybrid adversaries. IN could also think of small undersea swarming systems which are already on the design board to meet demands of clearing minefields, engaging enemy submarines, and carrying out ISR missions. Similarly, small aerial swarm weapon systems could prove exceptionally useful in dealing with air defense of carrier strike groups.


So ‘ere’s to you fuzzy-wuzzy, at your ‘ome in the Soudan; You’re a pore benighted ‘eathen, but a first class fightin’ man. 

Rudyard Kipling

Starting with the fundamental definition of Hybrid war in maritime context as “Naval irregular warfare plus cyber war and any other component that emerges in future”, the implications of cyber, sensors, and swarm warfare have been discussed in this article. However, new types of hybrid threats would keep surfacing and the IN has to be ready for them when called upon to counter them.

Hybrid war, being inherently nebulous and dynamic in nature, calls for constantly adapting naval doctrines and technologies to meet the emerging maritime hybrid threats.

Weapons and Sensors that Wait to Strike

(Published 24 Jun 2016, CLAWS)


Passive sensor triggered weapons have been in use for a considerable time by the military. They have been in form of Bangalore Torpedo, anti tank mines or anti personnel mines on land and as ground or moored mines at sea. Passive sensors have been extensively used on land for electronic support measures and at sea for detection of ships by submarines. One of the largest chains of passive sensors in the WWII era was Sound Surveillance System or SOSUS. It was a chain of hydrophone sensors located at various places in the Atlantic and Pacific Ocean. The main aim was locating Soviet submarines transiting the Greenland, Iceland, United Kingdom gap (GIUK gap). With developments in stealth technologies, other elements have been added to it such as the Surveillance Towed Array Sensor System (SURTASS), and it has become part of the Integrated Undersea Surveillance System (IUSS)[1].

One of the important weapons of the cold war era, that lay dormant until activated, was the anti submarine encapsulated torpedo MK 60 CAPTOR. It was a deep-water mine which could be laid by aircrafts, ships or submarines. The mine could distinguish between surface ships and submarines as well as between friendly and enemy submarines based on their acoustic signatures. It would thereafter launch the MK 46 torpedo, which would then acquire and attack the enemy submarine. Both Russia and China had also developed similar mines.

With the rapid advances in sensor technologies, it is now feasible to expect robustness, high quality, and reliability in commercially produced sensors. The sensors today are produced using novel signal processing methods, provide very high speeds, and utilize low cost electronic components. Similarly, two main developments in manufacture of chips, which have acted as a catalyst in exponential improvements in computing technologies, include, firstly, coupling of traditional electronics with optical components using Ge Laser to obviate usage of wiring in chips. The ongoing work at MIT’s Microphotonics center utilizes a series of subterranean tunnels instead of buried fiber cables for transmission of the laser[2]. This would achieve at least 100 times faster speeds than current systems. Secondly, the use of Mermisters or resistive random access memory (ReRAM) chips. These are 1000 times faster and can store twice as much data as flash memory chips. The main advantage is that ReRAM does not lose contents once power is switched off. [3] Further, they can be used in logic computations, implying thereby that both memory and computation functions can be carried out on the same chip[4].

Interestingly, Russia, China, and Iran have taken active interest in passive radar technologies. As per reports of a Rossiyskaya Gazeta’s online affiliate, in February 2015, Moskva-1 (developed by KRET) is a passive radar system, which would enable Russian troops to detect and identify airborne targets as far as 240 miles away without disclosing their location. It is understood that this could also be supplied to Iran[5].

The USAF had also released a request for information RFI RFI-PKS-0001-2012 for development of a Phased Array Antenna in respect of its Passive RF Sensing program. This involves development of analog and digital beam forming techniques for wideband phased array radar antennas that can operate over a 10:1 bandwidth[6]. The US Army too has evinced interest in such systems that lie in wait submerged at sea and could be launched at an opportune time[7].

The Defense Advanced Research Projects Agency (DARPA) has undertaken a project titled Upward Falling Payload (UFP) in which it is envisaged that drones would be made to lie in wait at concealed locations on the sea floor, for prolonged periods before being launched to the surface and into the air[8].

As per DARPA, “Nearly 50 percent of the world’s oceans are deeper than 4 km, which provides vast areas for concealment and storage. Concealment provided by the sea also provides the opportunity to engage remote assets that may have been dormant and undetected for long periods, while its vastness allows simultaneous operation across great distances. Getting close to objects without warning, and instantiating distributed systems without delay, are key attributes of UFP capability.”[9] The DARPA UFP program in its study phase, looked at long-range communications, deep-ocean high-pressure containment, and payload launch. It is understood that one of the firms that participated in the first phase was Sparton Electronics of De Leon Springs, Florida; this firm had worked to develop conceptual designs of a system with the potential to launch a plethora of non-lethal weapons like electronic warfare jammers, blinding lasers, and distracting light strobes upon surfacing.

The second phase would be development of proto types. The sub systems of the UFP program include; the pressure tolerant container or riser which would hold the payload for prolonged periods; the communication package, which would trigger the encapsulated payload to be launched to the surface, and the payload, which should be able to execute its function after it, is made to surface. To achieve the above aims the technologies that DARPA is looking at include, long endurance reliable electro-mechanical systems, very small sensors, small-unmanned systems, long-range underwater communications, navigation technologies etc. Phase 3 would be demonstrations of the systems at sea.

Once developed the UFP would provide pre-deployed sensors or non-lethal weapons in open seas. These could be  used by the US Forces for surprise deployment in times of international conflicts across the globe.

The author is not aware of any such futuristic research initiatives in respect of Indian Armed Forces by the Defence Research and Development Organisation in India.

Surface-to-Surface Missiles on Warships

(Published SP’s Naval Forces. Jun-Jul 2016 Vol 11 No. 3)

Surface-to-Surface Missiles on Warships

Blue water navies defend and attack with a variety platforms utilizing wide range of weapons. The three-dimensional operations of a formidable navy involve aircrafts, surface ships, and submarines. Each of these platforms has weapons designed for its specific role. A naval force far away from its homeport is thus fully capable of meeting threats arising from the air, surface or under water. A warship’s weapon outfit includes; missiles for anti air and anti ship warfare; torpedoes, depth charges and rockets for anti submarine warfare; and guns for anti surface, anti air, anti missile and naval gunfire support roles. Among the missiles, a warship’s outfit generally comprises of surface-to-surface missiles (SSM) and surface to air missiles (SAM). The SSM capability has rapidly advanced to the realm of the cruise missiles. The cruise missile owes it origins to the German V1/V2 rockets and mainly to the fact that manned aircraft missions had proved to be very expensive during the wars (loss of trained fighter pilots as well as expensive aircraft). Unfortunately, the cruise missile development until the 1970s resulted only in unreliable and inaccurate outcomes, which were not acceptable to the armed forces. Cruise missiles overcame their inherent technical difficulties and owe their tremendous success and popularity to notable technological advances in the fields of; propulsion (small turbofan jet engines resulted in smaller and lighter airframes); miniaturization of electronic components (smaller on board   computers led to much better guidance and control abilities); and high-density fuels, much better explosives, & smaller warheads.       Cruise missiles have become weapons of choice at sea because of their ability to fly close to the sea surface at very high speeds (sub-sonic/supersonic), formidable wave point programming, and lethal explosive capabilities. These make the missiles very difficult to detect and counter at sea.

A survey of some of the most powerful weapon platforms at sea would confirm that the surface-to-surface missile is one of the most potent armaments onboard. The significant surface-to-surface missiles include the Tomahawk, the Exocet, the Uran, the YJ-18, the RBS 15, the Brahmos, and the under development LRASM.


The Tomahawk Land Attack Missile (TLAM) has proved its versatility by successfully carrying out attacks on various types of land targets under hostile environments. The land attack Tomahawk is equipped with inertial and terrain contour matching (TERCOM) radar guidance. The missile constantly matches its database with the actual terrain to update its position. For terminal guidance, it uses the optical Digital Scene Matching Area Correlation (DSMAC) system for comparing the actual target image with the stored one. In TERCOM a digital characterization of an area of terrain is mapped based on digital terrain elevation data or stereo imagery and loaded in the missile. During flight, the missile compares the stored map data with radar altimeter data, missile’s inertial navigation system is updated, and the missile can correct its course if required. In Digital Scene Matching Area Correlation (DSMAC), a digitized image of an area is mapped and then embedded into a TLAM mission. While in flight the missile compares the stored images with the actual image for updating its inertial navigation system to enable course corrections.

The Tomahawk Weapon System (TWS) comprises of four major components; Tomahawk Missile, Theater Mission Planning Center (TMPC), Afloat Planning System (APS), Tomahawk Weapon Control System (TWCS) for surface ships, and Combat Control System (CCS) for submarines. Systems of the missile include Global Positioning System (GPS) receiver; an upgrade of the optical Digital Scene Matching Area Correlation (DSMAC) system; Time of Arrival (TOA) control, and improved 402 turbo engines. The missile is provided to ships as an ‘all-up-round’ (AUR). It includes the missile, the booster, and a transportation container which itself acts as a launch tube. TLAM-C has a conventional unitary warhead for attacking hardened targets, and TLAM-D has a conventional sub munitions (dispense bomblets) warhead for use against softer targets.

The Tomahawk TLAM Block III system upgrade had included jamming-resistant Global Positioning System (GPS) system receivers, Time of Arrival, and improved accuracy for low contrast matching of Digital Scene Matching Area Correlator, extended range, and a lighter warhead. The warhead for Block IV, the WDU-36, has an insensitive PBXN-107 explosive, the FMU-148 fuse, and the BBU-47 fuse booster.

Tactical Tomahawk has the capability to reprogram the missile during flight to attack any of 15 preprogrammed alternate targets or the warship can redirect the missile to any new GPS designated target. It is also able to loiter over a target area for some hours, and with its on-board TV camera, enable battle damage assessment & if required redirection of the missile to any other target. Addition of Network-centric warfare-capabilities is a major improvement to the Tomahawk where in it can use data from multiple sensors (ships, satellites, aircraft, UAVs etc.) to find its target as well as  share its own sensor data.

The new features in Block IV modifications include, a new multi mode passive seeker, As far as warhead is concerned, it is understood that Joint Multi-Effects Warhead System (JMEWS,  bunker busting feature) as well as Advanced Anti Radiation Guided Missile technology is being incorporated for increasing the warhead versatility. The TLAM-D contains 166 sub munitions in 24 canisters; 22 canisters of seven each, and 2 canisters of six each of Combined Effects Munition bomblet used with the CBU-87 Combined Effects Munition of the US Air force. Developments are also underway to use scramjet technology and make TLAM a supersonic missile with a speed of Mach 3.

The Exocet

The variant Block 3 MM40 is the ship-launched version of the Exocet. The basic body design of the Exocet (MBDA) is based upon on the Nord AS30 air to ground tactical missile. It has a solid-propellant booster and with a turbojet sustainer motor providing it a range of more than 180 km. It is a missile, which flies 1-2 m above the sea level and remains very difficult to detect until about 6 km from the target. It is guided inertially and has an active radar terminal guidance. The Exocet MM40 has three main versions Block 1, Block 2, and Block 3 for deployment from ships as well as coastal batteries. The Block 3 version can attack targets from different angles through GPS based waypoint commands. It weighs 670 kg, with a warhead weight of 165 kg.


The Russian Uran missile is a subsonic anti ship missile with active radar terminal guidance. It is the booster launch version of the Kh-35 U missile. Target designation and flight mission details are fed to missile prior to the launch. The missile is guided through inertial navigation system until it reaches the target zone. There after the radar is switched on for locating and tracking the target, once target has been acquired the missile traverses at very low altitude until it hits the target. It is said that it can be launched in sea states up to six. The acquisition range of the radar is 20 km. The ARGS-35E radar is being replaced by SPE Radar MMS built Gran-KE seeker. The Uran is highly secure even in a hostile counter-measure environment. It has a weight of 610 kg with a shaped charge warhead of 145 kg.


The YJ-18 is a Chinese anti ship cruise missile with a NATO designation of CH-SS-NX-13. It is said to be a copy of the Russian 3M-54E that is subsonic during the cruise phase and turns supersonic in the terminal phase. It has a range of 540 km. It may be having a BeiDou based inertial guidance with a warhead (explosive/ anti radiation) of 300 kg. It is said to be deployed from the Type 052D destroyers.


The RBS-15 is potent long-range surface-to-surface missile developed and manufactured by Saab Bofors Dynamics. It weighs 800 kg with a blast/ pre-fragmentation warhead of 200 kg. It has inertial, GPS guidance with active radar terminal homing. It has range of 250 km and cruises at subsonic speeds. The RBS-15 Mk3 missile system is claimed to have extremely flexible trajectory, an advanced target seeker with all weather capability and high defense penetration capability. Saab claims that it will support the missile system throughout its 30-year service life and offer in-country maintenance and other flexible maintenance solutions for its customers.


The BrahMos is a supersonic ramjet cruise missile being produced under a joint venture between the Indian Defence Research and Development Organisation and the Russian NPO Mashinostroeyenia. It is the fastest cruise missile in the world with a range of 290 km. Because of its high speed (close to Mach 3), it can penetrate current anti missile defenses. It has a wingspan of 1.7 m, diameter of 70 cm with a warhead of 200 kg. Its Block III version can carry out land attack also. It is understood that it has been tested in supersonic dive mode, without any seeker; against hidden land, targets with G3OM based navigation system, which can use GPS, GLONASS, as well as the Indian GAGAN satellite systems. Brahmos-II (K) is a hypersonic missile under development with a range of 290 km and a speed of Mach 7.It is likely to be propelled with scramjet air breathing jet engine.

Missiles of the Future (LRASM)

DARPA is developing an anti ship cruise missile with advanced stealth features as a replacement for the Harpoon missile for the US Navy. Lockheed Martin has been given a limited production contract for 90 missiles to meet US Navy’s urgent requirements. In August this year, the US Navy has officially designated the air-launched LRASM as the AGM-158C. LRASM will be fitted with a modified Mk 114 jettison-able rocket booster for launch from ships using the existing Mk 41 Vertical Launch System. LRASM is likely to herald autonomous targeting capabilities by utilizing on-board targeting systems. The LRASM would not require GPS, data links or any prior intelligence, it would be able to carry out positive identification of its target and track and attack it on its own. It will have advanced counter-counter measures to penetrate the enemy defenses under highly adverse conditions.

The basic design of LRASM is derived from the AGM-158B JASSM-ER with addition of a new weapon data link, radio frequency sensor (multi mode), altimeter, and better power system. It is a sea skimmer with a range of 370 km, which can be guided to target, given midcourse corrections, or function in standalone mode for selection of the target. The guidance system and the homing head have been designed by BAE Systems. These comprise, imaging infrared homing with automatic scene/target matching recognition, jamming resistant GPS/INS, passive RF and threat warning, ESM, radar warning sensors, and data link. Data link enables the missile to collate real time digital picture of the target zone from friendly assets. The emission data is autonomously classified, and acquired for generation of the missile’s attack trajectory. The LRASM can search and attack the target on its own using the active radar, the multi-mode homing head enables the missile to avoid being decoyed and hitting the incorrect target. It is claimed that the missile can also operate in swarms and has land attack capability.


Cruise missiles are very expensive weapons costing millions of dollars per piece. Therefore, selection of the target becomes a difficult task, as cost benefit analysis has to be carried out prior to launching the cruise missile on its mission. However, with their minimal signatures in the visual, infrared and radar spectrums they become weapons of choice in mission of high priority and stealth.

It appears that the trend towards developments of supersonic/hypersonic scramjet cruise missiles will continue to gather momentum and such missiles could be in the naval inventories by 2020. Coupled with hypersonic missiles, would be real time target data updating and guidance by extremely fast on-board computers and satellite-based systems. The kinetic energy of hypersonic cruise missiles would be a lethality multiplier against targets at sea and therefore such a missile would be a formidable weapon without a credible countermeasure as on date. The costs continue to increase with new developments; however, maintenance requirements appear to be reducing with canisterised missiles. The proliferation of precision guided missiles would continue to increase with reductions in cost of components, electronics, and software.

New Nukes on the Block?

(Published 06 Jun 2016, CLAWS)

‘As long as the United States continues to have nuclear weapons, we must ensure that they remain safe, secure, and effective without the use of underground testing,”

Don Cook, NNSA Deputy Administrator for Defense Programs[1]


In October 2015, USA completed testing of upgraded Nuclear Earth Penetrating bomb B61-12. The aim was to extend the life of B61 Mod 7 and Mod 11 strategic bombs by 20 years[2]. The upgrades include scalable nuclear yield (The B61 family of weapons can be configured with a wide variety of yields, including 0.3, 1.5, 5, 10, 45, 60, 60, 80, 170, and 340 kilotons), precision guidance and advanced safety mechanisms.

It is understood that strategic assets like ballistic missile facilities, command, control & communication centers, shelters for political leadership etc are located in tunnels at depths varying between 200 meters to 700 meters. These have been termed as strategic “hard and deeply buried target (HDBT)” by NATO countries and it is against such targets that Nuclear Earth Penetrating bombs are intended to be used.

Conventional weapons have the capability to penetrate to depths as much as the nuclear earth penetrator weapons (NEPW) but they are not as effective against the HDBTs. The energy transfer of NEPWs into ground is far more effective than surface or aerial bursts of even nuclear weapons. It is said that a 300-kiloton NEPW is as effective as a 6-megaton surface burst against HDBTs. Further, the accuracy requirements (Circular Error Probable, CEP) for surface bursts are more stringent than NEPWs for HDBTs to achieve the same kill probabilities. This brings in to focus two facts viz. that NEPWs require much less radioactive material and that with increasing accuracy of hit the damage potential keeps on increasing.

Sandia National Laboratories have been carrying out research work on the Earth Penetrators since the 1960s. One of their newer programs is the feasibility study program “Robust Nuclear Earth Penetrator program (RNEP)”. The aim of this program is to study feasibility of designing RNEPs which, can tackle a larger number of targets than the B61-11. The general terms of reference indicate that RNEP should be capable of reaching a specified depth, should be able to survive and penetrate the target, and should perform better than B61-11in terms of functionability, safety, security, & reliability. Sandia National Laboratories have the credit of building the most complicated nuclear safety mechanism called the ‘Micro Guardian’ in 1990s. This ensures that the nuclear weapon does not detonate until a predefined sequence of events is completed. It is said that the size of this system is 10 mm x 6 mm x 5 mm, and it forms a part of the optical micro-firing system[3]. These developments highlight the march of Micro electro-mechanical systems (MEMS) as well as the Nano electro-mechanical systems (NEMS) into the nuclear arsenal arena.

It need not be stressed that arming and detonation of a nuclear weapon should not take place accidentally, however it is also to be ensured that the bomb once armed must not only hit the designated target but also explode. These conditions present a formidable technological challenge in designing of the arming, fusing, and firing mechanisms of  nuclear bombs. This requires requisite robustness and multiple redundancies as also assured reliability of functioning. The MEMS/ NEMS have gained credibility mainly due to their compactness and minimal moving components as compared to the early analogue as well as digital counterparts. Programs such as the RNEP of Sandia National Laboratories would not only benefit NEPs but also conventional weapons as well. The availability of such devices and the fact that they have improved the resistance to failure of key components in fusing, arming, detonators, and neutron generators by many magnitudes has spurred research into next generation of nuclear weapons.

Though the consensus over the term Fourth Generation of nuclear weapons is still debatable, it can be safely stated that it would invariably be those classes of nuclear weapons which are triggered using advance triggering mechanisms such as  super lasers, magnetic compression or antimatter (this also under active research!!). This would than result in a thermonuclear explosion of a few liters of deuterium-tritium mixture (equivalent of hundreds of tons of TNT). The main source of yield would not be fission reaction of the first three generations but a distinct fusion reaction, which would classify the next generation.

The stage is set for, NEMS to usher in unprecedented robustness, reliability, and precision in CEP, nEMs to replace conventional explosives and provide much greater explosive power[4], and advanced triggering devices & fusion yields to herald fourth generation nuclear weapons. The possessor would not only be able to unleash a swarm of conventional weapons but also carryout devastating assault without breaching the kiloton/ megaton taboo of first strike!






Nanoenergetic Materials (nEMs) in Conventional Ammunition

Nanoenergetic Materials (nEMs) in Conventional Ammunition

 Nanotechnology “could completely change the face of weaponry,”

Andy Oppenheimer, Jane’s Information Group[1]

On 11 September 2007, Russians tested Father of All Bombs (FOAB), an Aviation Thermo baric Bomb of Increased Power (ATBIP). It was said to be the most powerful conventional bomb in the world, with a 7-Ton explosive mixture resulting in a devastating effect equivalent to 44 tons of TNT[2]. It was hinted that the FOAB contained a liquid fuel, such as ethylene oxide, mixed with energetic nano-aluminium powder, which was dispersed by a high explosive booster. Some reports speculated that the liquid fuel was purified using nano-filters. What caught the imagination of defense experts was the fact that the Russian FOAB had less fuel than the similar US device Mother of All Bombs (MOAB), the GBU-43/B Massive Ordnance Air Blast bomb, but was four times more powerful. It was also probably the first time that the nonprofessional learned of the lethal uses of nanotechnology. Not much information is available through open sources about the developments involving nanotechnology in explosives, much of it has to be gleaned from research papers and patents (for e.g. Patents like US6955732 – Advanced thermo baric explosive compositions and WO2013119191A1 – Composition for a fuel and air explosion).

            Since 2004, ‘Combat Safe Insensitive Munitions’ concept has shifted the focus of safety from a pure materials approach to making marine explosives insensitive to a platform based approach based upon mechanics to increase insensitivity[3]. US Navy has been at the forefront of R&D into new energetic materials since a long time and it is opined that nanotechnology enabled energetic materials would form the backbone of the future defense systems. Timely induction of nano enabled energetic systems with controlled energy release is the focus of current research at institutes like the U.S. Naval Academy, Naval Surface Warfare Center, and the University of Maryland.

            In simple terms, Nanoenergetic materials (nEMs) perform better than conventional materials because of much larger surface area, which increases speed of reaction and larger energy release in much shorter time. Addition of Superthermites[4] (nano-aluminium based) have shown instantaneous increase in explosive power of existing compositions[5]. Further, use of nano-sized materials in explosives has significantly increased safety and insensitivity by as much as over 30% without affecting reactivity. It is predicted that nEMs would provide the same explosive power at mass up to two orders of magnitude less than the current explosive systems[6].

In rocket, propellants nEMs have shown similar capabilities at Los Almos National Laboratories with nitrogen-energized nEMs[7]. In addition, incorporation of more than one burning rate in rocket propellants has given rise to novel design options by creating grains with continuously varying properties along the length as well as across the radius of the grain in Functionally Graded Materials (FGM).

While Nanosizing of high explosives leads to increasing their explosive power[8] and decreasing their sensitivity to external forces[9], it also decreases its thermal stability. The shelf life of such explosives could therefore stand reduced, however, some patents reveal that this issue has also been resolved technically (e.g. patent US20120227613 Thermal enhanced blast warhead). In India the work on explosives and propellants is being undertaken at HEMRL, a DRDO laboratory, and it is understood that the research in nEMs is progressing satisfactorily.


Nanotechnology is permeating in all fields of design & manufacturing of weapons and ammunition. It is bringing unprecedented precision in weapon systems, robustness in triggering mechanisms and opening new frontiers in propellant and pyrotechnic functioning. In addition to explosive and propellants, Nanomaterials have ushered in innovative improvements in many characteristics of ammunition such as guidance, penetration capacity, embedded sensors for monitoring condition, embedded antennae for guidance and so on.

It can be envisaged that nEMs would replace the conventional explosives in the next decade. This would provide existing conventional weapons with explosive powers higher in magnitude by a factor of two and enhance the safety to external stimulation by at least 30%. In simple terms, a missile warhead having an explosive content of 200 kg of TNT equivalent would have an explosive power of 20,000 kg of TNT equivalent when substituted with nEMs material of same weight of 200 kg!

This advancement could displace Tactical nukes from the battlefield.

What can also be foreseen is the mushrooming of new classes of extremely precise and lethal small/micro weapon systems, which could be scaled down by at least second order of magnitude from the current systems. Thus creating space for the likely paradigm shift from bigger & larger to the smaller & numerous holdings of weapons. This in turn would herald the era of Swarm Warfare.

[3] Insensitive munitions:

Improve the safety and survivability for Armed Forces and civilians in urban areas or near combat zones because they can safely be stored at closer distances. Reduce the vulnerability of platforms and resources against unintended or hostile aggression, violent reactions with blast overpressure and fragmentation damages are under control. Maximize the storage capabilities and improve flexibility logistics: IM can safely be carried by land/sea/air; storage platforms can be closer together and are key to Inter-Operability between the Armed Forces.

[4] Nano-Thermite or Super-Thermite is a metastable intermolecular composite (MICs) containing an oxidizer and a reducing agent, which are intimately mixed on the nanometer scale. This dramatically increases the reactivity relative to micrometer -sized powder thermite. MICs, including nano-thermitic materials, are a type of reactive materials investigated for military use, as well as for general applications involving propellants, explosives, and pyrotechnics.

Neuromorphic Chips – Defence Applications

(Published Claws 30 Apr 2016 )


..And I had an opportunity to grow from the time where we couldn’t make a single silicon transistor to the time where we put 1.7 billion of them on one chip!

                                                                                 Gordon Moore, Cofounder Intel

Last year Kris Gopalakrishnan pledged $ 50 mn at IISc and IIT Madras on research that seeks to model next level computing based on the functioning of the Brain.[1] Neuromorphic engineering is an emerging interdisciplinary field that involves designing sophisticated devices based on the complex neural circuits of the brain. It uses principles of the nervous system for engineering applications to achieve a better understanding of computations occurring in actual biological circuits and utilize the unique properties of biological circuits to design and implement efficient engineering products. Neuromorphic chips aim to mimic the massive parallel computing power of the brain, circumvent the size limitations of traditional chips, and consume less power. It is also predicted that such chips could adapt in response to stimuli. As a technology demonstrator, P. Merolla et al [2] at IBM have developed a 5.4-billion-transistor chip (TrueNorth) with 4096 neurosynaptic cores interconnected via an intra-chip network that integrates 1 million programmable spiking neurons and 256 million configurable synapses. With 5.4 billion transistors, occupying 4.3-sq cm area TrueNorth has ∼428 million bits of on-chip memory. In terms of power, consumption where a typical central processing unit (CPU) consumes 50 to 100 W per sq cm the TrueNorth’s power density is 20 mW per sq cm only. This qualifies it to be a good candidate for ushering in green technology in to computing.[3] However, for purposes of clarity TrueNorth is not a brain, it is inspired by the brain[4] and mimics some functions of the brain to carry out computations.

Market for Neuromorphic Chips

The main factors, which have driven research and development of neuromorphic chips, are tremendous demand for data and data analytics, miniaturization of sensors, ingress of Artificial Intelligence into software of almost all intelligent machines and high cost of further miniaturization of integrated circuits. These factors have spurred the demand and growth of the market for neuromorphic chips, which is expected to grow at a CAGR of 26.31% between 2016 -2022.[5] One of the key areas where such systems would need break-through research would be in design of algorithms since biological systems autonomously process information through deep learning whereas any human designed chip or system would be limited by human designed algorithms. The applications areas currently comprise sensors in military as well as medical fields.

Military Applications

Militaries today are coping up with an exponential increase in the amount of data from a wide variety of sensors.  Unprecedented data collection has severely strained the limited available bandwidth for military use. The data needs to be processed, as close to the sensor as possible before further transmission therefore sequential computational techniques with their large size and power requirements are not very efficient in this regard. NeuroSynaptic chips can carry out this parallel task much more efficiently.

DARPA had initiated a project called Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE), in 2008 and had contracted it to IBM and HRL. It has funding of over $ 100 mn. The aim of SyNAPSE is stated ‘to build an electronic microprocessor system that matches a mammalian brain in function, size, and power consumption. Further, it should recreate 10 billion neurons, 100 trillion synapses, consume one kilowatt, and occupy less than two liters of space’.[6]

The US Army has projected a requirement for a high-performance, low-power bio-inspired parallel processor. This would be integrated in to cognitive communication systems and image processing platforms on unmanned vehicles. The project is being undertaken by Physical Optics Corporation (POC) under their BRAINWARE processor program.

The U.S. Air Force has projected a requirement to develop a new class of advanced, wide field of view (WFOV) imaging sensors that sample the radiation field in multiple modes: spectral, temporal, polarization, and detailed object shape. These multimodal sensors are for deployment on high altitude ISR functions of drones. Scaled down versions are required for use with autonomous micro-air vehicles (MAV) for guidance, navigation, and control. Two types of bio-inspired multimodal sensors, one operating in the visible wavelength regime, and the other operating in the infrared wavelength regime are being developed by The Spectral Imaging Laboratory (SPILAB) in collaboration with the University of Arizona. Both sensors will have a neuromorphic processing capability based upon visual brain areas of insects and crotalid snakes.


It is apparent that neuromorphic chip based computational systems scalable to the capabilities of the human brain are  a clear possibility provided an all-round research and development effort is synergized in hardware, software, architecture, and simulation & understanding of functioning of the brain. The neuromorphic chips as well as quantum computing have ushered in a paradigm shift from the focus on microchips to that of the system as a whole.

In the ultimate goal of mimicking the human brain, it is likely that development of artificial brains of smaller species or specific parts of the human brain may turn out to be more enchanting purely from a commercial point of view. The impetus to the rapid development in neuromorphic systems would be provided by the availability and applications of such systems for large-scale commercial utilization.

Proactive Defense Infrastructure Planning of Indian Island Territories

A Conceptual Case Study of Lakshadweep (Minicoy and Suheli Par Islands)

By Rear Admiral Dr S. Kulshrestha (Retd.), Indian Navy  and Rahul Guhathakurta, IndraStra Global


The strategy for coastal and offshore security has been articulated in the document “Ensuring Secure Seas: Indian Maritime Security Strategy” of the Indian Navy. The strategy envisages ‘to reduce, counter and eliminate the threat of armed attack by sub-conventional groups, and also influx of arms and infiltration by armed attackers from the sea, against coastal and offshore assets’.

The chapter “Strategy for Conflict’ covers the actions for coastal and offshore defense. Essentially the operations will be carried out by the Indian Navy in synergy with the Indian Army, Air Force, Coast Guard, and other security agencies.

Defending India’s Coast, Offshore Assets, EEZ and Island Territories.

India has a formidable naval force with both blue water and littoral capabilities; it also has a credible Coast guard, which would work in unison with the Indian Navy in times of war. Further India has put in place a powerful template for marine domain awareness, intelligence and protection of the coastal and offshore areas, in the aftermath of the terrorist attack of 26 Nov 2008. Some of the measures include; setting up of Multi Agency Centres (MAC) for intelligence inputs and reports; registration of fishing vessels by states; placing in orbit Indian Regional Navigation Seven Satellite System and satellite GSAT 7 ; setting up of a coast wide radar chain; raising Marine Police force, Marine Commandos Rapid Reaction Force and a Sagar Prahari Bal (SPB);setting up layered patrolling; putting in place The National Command Control Communication and Intelligence network (NC3IN) etc.

Prominent Gaps in Coastal and Offshore Defence

Thus, the layered defence of Indian coast and its offshore areas consists of Indian Navy, the coast guard, the marine commando & Sagar Prahari Bal (SPB) and the marine police. All these are info-linked for maximum advance knowledge and in a way form a net worked coalition. However, there apparently is a gap as far as setting up the coastal and offshore area defences per se is concerned. It lacks the delay, denial, disruption, and demoralizing (D4) capability, which is essential in today’s environment. This capability should be acquired by leveraging the perceived threats presented by the submarine, mines, small craft and cruise missiles.

The defence plan should be an asymmetric and proactive approach to defence with defining it as a zone that comprises two segments of the defence environment:-

·                     Seaward- the area from the shore to the open ocean, which must be defended to thwart expeditionary forces at sea.

·                      Landward- from the shore to the area inland that can be supported and defended directly from the shore.

The existing gap in Indian defences can be obviated with very potent defence elements by including:-

·                     Comprehensive assessment of threats from expeditionary forces to ports/ harbors.

·                     Procurement of midget/ miniature submarines with torpedoes and mine laying capability along with arrays of underwater sensors for environment, intrusion information, navigation and communication.

·                     Procurement of UAVs/USVs with intelligent software for remote operations as swarms.

·                     Procurement of Unmanned Underwater Sensor and Weapon Carriers capable of transmitting integrated underwater picture to fixed or mobile stations, firing torpedoes and laying mines.

·                     Procurement and laying of cable controlled mine fields, other mine fields across various depths zones.

·                     Coastal extended reach anti ship cruise missile batteries.

·                     Coastal gun batteries with ability to carry out precision attack on surface ships at ranges greater than 50 km.

·                     All systems networked for an ironclad protection of the Indian Coast and offshore assets and territories.

·                     Development of weapons specific for use in coastal areas and

·                     Development of systems for collection of oceanographic information.

A robust Indian coastal and offshore defense plan and its implementation is an essential element of economic wellbeing of India, as it would ensure security of sea trade, shipping, fishing, marine resources, and offshore assets as well as security of the EEZ.

Rights of a Coastal State w.r.t. EEZ

Within its EEZ, a coastal state has sovereign rights for exploring, exploiting, conserving, and managing natural living and non-living resources of the waters superjacent to the seabed and its sub soil. Further, it can exploit and explore production of energy from water, winds, and currents. The EEZ remains an open zone with freedom of innocent passage for all. The EEZ legal regime is different from that governing territorial waters and high seas, and contains certain characteristics of both.

However, in a recent judgment regarding the Enrica Lexie (Italian marines) case, the Supreme Court of India has declared the region between the contiguous zone and the 200 nautical miles in to the sea as ‘High Seas’. The Supreme court has said that Article 97 of the United Nations Convention on Law of the Sea (UNCLOS) is not applicable as shooting was a criminal action and not a navigation accident.

China has been maintaining its right to regulate foreign military activities in its EEZ, as it feels that it has the right to prevent any activity that threatens its economic interests or security. It also asserts that its domestic laws have jurisdiction in its EEZ. The Chinese law requires foreign entities to obtain prior approval to carryout resource exploitation, fishing, and marine research. As far as military activities are concerned, it holds them as prejudicial to ‘peaceful purposes’ provision of the Laws of the Seas Convention. This interpretation has led to a number of minor standoffs between it and the United States of America.

India is also one of the countries, which mandate prior permission before any maintenance, or repairs are carried out to the submarine cables running on the floor of its EEZ.

With respect to military activities by foreign militaries in the EEZ, India along with Bangladesh, Brazil, Cape Verde, Malaysia, Pakistan, and Uruguay require obtaining of prior permission. North Korea has prohibited any such activity within 50 nm of its territory and Iran has completely prohibited the same.

As far as oceanographic surveying is considered, again some countries require prior permission, in fact, China registered protests against the activities of USNS Bowditch and India against HMS Scott and USNS Bowditch, which were gathering military data by undertaking oceanographic survey. Coupling the above with increased proliferation of submarines in the region, the instances of clandestine underwater and ASW surveys would only increase. There are bound to be incidents involving intruder submarines in future and states would therefore be monitoring activities in their EEZs diligently.

EEZ Security Components

Two essential components of effective EEZ security management comprise of surveillance and deterrence. Some of the drawbacks of EEZ surveillance systems in use today include; inability of patrol boats to carry out surveillance, since their missions are area denial, SAR or interdiction; UAV’s have much better sensor packages but need a large infrastructure for 24/7 surveillance; HF radars are affordable but need very large areas for installation; Microwave radars suffer from limited horizon; and patrol aircraft incur huge costs. Since radars have difficulty in automatically identifying unknown and devious small vessels and the electro optic systems are heavily weather dependent, there is requirement for add on sensors to carry out effective monitoring of EEZ. In fact, a complete EEZ surveillance system should be able to cater to all the facets of EEZ activity be it , terrorism, drug and human trafficking, piracy, smuggling, coastal security, Search and rescue, sea traffic control, pollution control, illegal fishing, illegal arms supply and exploitation of natural resources of solar, air, wave, minerals, oil and gas. For such an extensive requirement a cooperative, synergetic and system of systems approach between various agencies involved would be paramount.

The surveillance platforms would include the following:-

·                     Unmanned undersea vehicles, sonar arrays, patrol submarines, and other under water sensors.

·                     Remotely operated vehicles, unmanned surface vehicles, offshore platforms, sensors for activity monitoring, and patrol boats.

·                     Vessel Traffic Management System (VTMS), communication networks, control centers, pollution monitoring centers, surface and navigation radars, and electro-optic systems.

·                     Unmanned Ariel Vehicles, patrol aircraft, helicopters, aerostats, and sensors.

·                     Observation and communication satellites.

Coming to the deterrence capability in the EEZ, it has to be a non-military option during peacetime, which brings the discussion to deployment of Non Lethal Weapons (NLW) and the need to develop them for the EEZ environment. Conflicts in the EEZ are definitely going to be unconventional and it would be difficult to distinguish the adversary from the neutrals or friendly vessels. This may lead to conflicts where use of lethal weapons may not be permissible. Non-lethal weapons would provide tactical as well as strategic benefits to the EEZ protection force in the global commons. NLW would enable options for de-escalation of conflicts, avoid irretrievable consequences of using lethal options, and result in deterring activity without loss of lives and damage to material. NLWs have to be cost effective and easy to operate, as different varieties in varying numbers would be required. However to ensure a calibrated approach, across the spectrum of conflict, there is also a need for NLWs to be doctrinally integrated with the regular naval forces to enable them to tackle a developing situation in the EEZ.

Defense of Island Territories

The defence of the Island territories has to be structured as a mix of the Coastal and EEZ defence plans. The defence plan in case of the Islands should be an asymmetric and proactive approach to defence with defining it as a zone that comprises three segments of the defence environment:-

·                     Seaward- the area from the shore to the open ocean, which must be defended to thwart expeditionary forces at sea.

·                     Landward- from the shore to the area inland that can be supported and defended directly from the shore.

·                     From the Sea-  from the sea by warships and submarines in case, an incursion has already been made on an unprotected/ inadequately protected island. As well as drawing from offensive infrastructure at the islands in the vicinity.

The surveillance and defense components have to be drawn from the coastal and EEZ defense plans and augmented by use of warships and submarines at sea.

“Even if Chinese naval ships and submarines appear regularly in the Indian Ocean, so what?” he asked. “As the largest trading nation in the world, maritime security in the Indo-Pacific cannot be more important for China. The Chinese navy has to protect its overseas interests such as the safety of personnel and security of property and investment. Much of these are along the rim of the Indian Ocean.” – Zhou Bo, honorary fellow, Academy of Military Science, Beijing, Jul 2015

An Academic Case Study of Proactive Defense Infrastructure at Two Lakshadweep Islands (Minicoy and Suheli Par)

The Lakshadweep islands lie between 8° – 12 °3′ N latitude and 71°E – 74°E longitude about 225 to 450 km from the Coast of Kerala. There are 12 atolls, 3 reefs, and five submerged banks. In all, there are 36 Islands, with a total land area of 32 sq km; Lakshadweep islands have a lagoon area of 4200 sq km and 20,000 sq km of territorial waters. It provides a large swath of 4, 00,000 sq km of Exclusive Economic Zone.

Map 1: Proximity Analysis of Minicoy Island and Suheli Par with respect to SLOCs (Interactive map available at


Minicoy is the southernmost island in the Lakshadweep. It lies between 8° 15’ to 8° 20’ N and 73° 01’ to 73° 05 E with an area of 4.4 sq km including the Viringli islet. Minicoy is separated from the rest of Lakshadweep by the nine-degree channel and from the Maldives by the 8° channel. It is an independent oceanic island that does not belong to either the Maldives or the Lakshadweep bank.

Suheli Par

It is located at 10°05′N 72°17′E / 10.083°N 72.283°E / 10.083; 72.283, 52 km to the SW of Kavaratti, 76 km to the south of Agatti, 139 km to the west of Kalpeni and 205 km to the NNW of Minicoy, with the broad Nine Degree Channel between them. There are two uninhabited islands, Valiyakara at the northern end with a lighthouse ARLHS LAK-015, and Cheriyakara on the southeastern side. These two islands have a long sandbank Suheli Pitti between them.

Criterion for selection of the island of Minicoy and Suheli par

Some of the criterion for selection of the islands of Minicoy and Suheli par are:

Minicoy and Suheli Par would synergistic-ally straddle the 9-degree channel, one of the most important SLOC not only for India, but also for the Indo-Pacific region and also for China. The security of the SLOC would be ensured pro-actively by developing the defense structure at both islands.

·                     Minicoy is inhabited and Suheli Par is not, thus providing two distinct classes of islands.

·                     Minicoy is geologically different from other islands in the Lakshadweep.

·                     Both have large lagoons.

·                     Both need to be developed for prosperity and connectivity of the region with main land.

·                     Both have poor connectivity with mainland.

·                     Both can provide security structures for EEZ and its regulation

·                     Main Features of Proactive Defense of Islands.

The main features of the conceptual structures include:

·                     Airstrips for use by tourists as well as defense.

·                     Small harbor facilities

·                     Submarine piers

·                     Mini/midget pens

·                     Staging facilities

·                     Coastal gun and missile batteries

·                     Mooring Buoys

·                     Off Shore ammunition storage

·                     Air defense capability

·                     Radar and underwater sensors

·                     Strategic Oil Storage Facility

·                     Command, Communications, and Control Center for Indian Navy

·                     Strategic Communication facility

·                     Storm Warning and Fisheries information center

·                     Ocean Surveillance stations and cabled Oceanic Information Observatories

·                     Floating sun power panels

·                     Offshore Desalination plants

·                     Facilities for Tourists

Linkages with MDA, ODA, and OICZ

It is important that any academic exercise for development of a proactive defense infrastructure of island territories consider concepts of Maritime Domain Awareness (MDA), Oceanic Domain Awareness (ODA), and Ocean Information Consciousness Zones (OICZ). MDA focuses upon the maritime security environment specific to naval operations; the ODA focuses upon the overarching oceanic environment. Both are technology intensive and require sophisticated sensors and computational capabilities.MDA has tactical, regional, and strategic components whereas the ODA is strategic knowledge based architecture. Both require elaborate data and information fusing interface with myriad of interconnected agencies. The MDA primarily needing vast inputs from commercial, intelligence and security agencies and the ODA from advanced research, academic and scientific communities. The ODA is conceptualized as a comprehensive 3D+ knowledge zone up to India’s EEZ, the OICZ on the other hand is a collaborative approach at sharing oceanic information, processing it as required and archiving it for use at a later date. ODA can be established by a country individually, but OICZ requires transfer / sharing of scientific knowledge and technology between nations. Benefits of ODA accrue to the nation whereas OICZ would empower the region. Both are strategic in nature.

The usage of “geo-spatial tools” behind the “Conceptual Proactive Defense Infrastructure Plan” for Minicoy and Suheli Par

In the field of geopolitical studies, spatial analysis driven by various geographic information system (GIS) technologies helps strategic experts in computing required and desired solutions. In this analysis of Minicoy Island and Suheli Par, Google My Map API is used to perform a variety of geo-spatial calculations by using a set of easy to use function calls in the data step. In layman’s term, a layer-by-layer computational analysis of geographic patterns to finding optimum routes, site selection, and advanced predictive modeling to substantiate this analysis has been carried out. These concepts are formulated by considering the land reclamation factors and available details of Integrated Island Management Plan of Government of India (GoI) for Lakshadweep Islands. However, there are certain limitations associated with this analysis with respect to bathymetric data, which has not been considered for evaluation purpose due to lack of availability of such data in open/public domain. Further, these interactive custom maps can be easily exported into KMZ format and can also be embedded seamlessly with other websites for further distribution.

Considering all the factors discussed hitherto the maps are embedded in this article, depicting the proactive defense infrastructure plan for Minicoy and Suheli Par have been developed.


India’s EEZ and island territories face threats of disruption of energy supplies, piracy, and acts of terrorism, in addition to the fact that other nations are keen to poach in to the fisheries and seabed wealth. The security of the EEZ and island territories is therefore a matter of India’s national interest and need exists for boosting the surveillance and augmenting security arrangements of EEZ’s and island territories. Even though, an ambitious plan for coastal security and maritime domain awareness has been put in place, it needs to be further strengthened and stitched together so that the security of EEZ and Island territories functions as a comprehensive entity with synergies across the various agencies involved.

The academic exercise undertaken above in respect of Minicoy and Suheli Par islands demonstrates that it is feasible to provide effective SLOC protection, achieve maritime dominance in a limited area of interest, provide support to second strike capability and utilize space and oceans for surveillance, intelligence, science, and communications purposes.

Time for a proactive approach to plan the defense of EEZ and island territories is now!
