Introduction
The advent of hypersonic weapons signifies a significant advancement in military technology, like the introduction of intercontinental ballistic missiles during the Cold War. These weapons, characterised by their capacity to maintain flight at speeds exceeding Mach 5 (approximately 6,174 km/h or 3,836 mph at sea level), combine extraordinary speed with manoeuvrability, presenting challenges to existing defence systems and influencing strategic planning (Congressional Budget Office, 2023).
The contemporary hypersonic arms race is centred on two categories of weapons: Hypersonic Glide Vehicles (HGVs) and Hypersonic Cruise Missiles (HCMs). HGVs are propelled by ballistic missile boosters, achieving hypersonic velocities before detaching and gliding unpowered through the atmosphere while performing complex manoeuvres, whereas, HCMs employ air-breathing propulsion systems, such as scramjets, to sustain continuous hypersonic flight throughout their missions (National Institute for Defence Studies, 2024).
This paper provides an examination of hypersonic weapon systems by analysing their technical design features, operational capabilities, national development initiatives, and strategic implications. The analysis is based on open-source intelligence, government documents, and technical literature to provide an exhaustive evaluation of this transformative technology. The scope encompasses both the engineering challenges that have been addressed and those that remain, as well as the operational and strategic contexts in which these weapons are deployed.
Technical Design and Engineering Challenges
Aerodynamic Design Principles
The aerodynamic design of hypersonic weapons presents unique engineering challenges that are distinct from those of subsonic/supersonic aircraft and traditional ballistic missiles. At hypersonic speeds, the airflow behaviour is dominated by high-temperature gas effects, chemical reactions, and nonequilibrium thermodynamics, which fundamentally alter the conventional aerodynamic assumptions (Patsnap Eureka, 2025).
HGVs utilise lifting-body configurations optimised for high lift-to-drag ratios during atmospheric gliding. The DF-ZF (China) and C-HGB (United States) feature wedge-shaped or conical aeroshell designs that generate sufficient lift to maintain the altitude while allowing lateral manoeuvrability. These designs must balance competing requirements, such as adequate lift for an extended range, minimal drag to preserve speed, and sufficient control authority for terminal manoeuvring (Jamestown Foundation, 2016).
DF-ZF (China): This vehicle is frequently described as having a lifting body or waverider design. Its wedge-like, flatter aeroshell is designed to harness the shockwaves produced during flight to create lift, thereby greatly enhancing its range and ability to manoeuvre across different trajectories.
C-HGB (United States): This model is characterised by a slender, bi-conical, or tri-conical form instead of a flat wedge. Its conical, axisymmetric aeroshell is designed for high manoeuvrability, with a strong emphasis on aerodynamic stability and thermal management, drawing its lineage from earlier U.S. experimental re-entry vehicles.
The management of shock waves is a critical design consideration. At hypersonic speeds, strong shock waves form at the leading edges, creating areas of extremely high pressure and temperature. Computational Fluid Dynamics (CFD) simulations, validated through wind tunnel testing and flight experiments, guide the shaping of vehicle surfaces to manage shock interactions and minimise aerodynamic heating. The interaction between aerodynamics and vehicle dynamics becomes particularly complex during a manoeuvring flight, where changes in the angle of attack alter the entire flow field (University of Notre Dame Hyperlab, 2024).
Thermal Protection Systems
Thermal management is the most formidable challenge in the design of hypersonic weapons. At speeds exceeding Mach 5, aerodynamic heating generates surface temperatures above 2,000 °C (3,632 °F), with peak temperatures at the leading edges and nose sections reaching 3,000 °C (5,432 °F) during prolonged flights (Congressional Budget Office, 2023).
Carbon-carbon (C/C) composites are the best materials for high-temperature areas. They remain strong in extreme heat and are lightweight. The Space Shuttle used these materials for heat protection, demonstrating their effectiveness; however, hypersonic weapons require even tougher materials because they fly longer in the atmosphere (NASA, 2008). Ultra-High-Temperature Ceramics (UHTCs), such as zirconium diboride (ZrB2) and hafnium diboride (HfB2), are other options for parts such as leading edges and nose caps. These materials resist oxidation and heat well but are brittle, making them difficult to use. Ceramic Matrix Composites (CMCs), especially silicon carbide fibre-reinforced silicon carbide (SiC/SiC), work well under high heat and are less likely to break (Nature Communications, 2024). Ablative thermal protection systems, such as phenolic-impregnated carbon ablator (PICA), are efficient in areas with extreme heat conditions. They absorb heat by breaking down but can only be used once; therefore, they are disposable and suitable for use in weapons (MDPI Polymers, 2025).
Propulsion
Scramjet Technology helps hypersonic missiles fly by compressing air with shock waves, mixing it with fuel, and burning it at high speeds. This method does not require complex machinery, making it simpler and lighter for speeds over Mach 5 (Johns Hopkins APL, 2005). The main challenge is burning fuel quickly because air moves through the engine rapidly at Mach 6. This is like “keeping a match lit in a hurricane” (Congressional Budget Office, 2023). Hydrocarbon fuels, such as JP-7 and JP-10, are practical but burn slower than hydrogen. The X-51A Waverider showed scramjet flight for about 200 seconds in 2010, paving the way for future weapons. Current projects, such as the Hypersonic Attack Cruise Missile (HACM) and Hypersonic Air-Launched Offensive Anti-Ship Missile (HALO), build on these successes while solving integration issues (Forecast International, 2025).
Hypersonic Glide Vehicles (HGVs) need rocket boosters to reach high speeds for gliding. Two-stage solid rocket motors are optimal for ground and sea launches because they are powerful, easy to store, and simple to use. The U.S. Army’s Long-Range Hypersonic Weapon (LRHW) and the Navy’s Conventional Prompt Strike (CPS) use a common booster for launching from ships, submarines, and ground launchers (Defence Security Monitor, 2025). Air-launched HGVs, such as the AGM-183A Air-Launched Rapid Response Weapon (ARRW), use smaller boosters for bombers and fighter jets. These systems trade range for flexibility, allowing for quick deployment in different situations. Despite these challenges, the ARRW program successfully tested boosters in 2022, proving that air-launched systems also work (National Institute for Defence Studies, 2024).
Navigation, Guidance, and Onboard Computing
Inertial Navigation Systems
Hypersonic weapons employ Inertial Navigation Systems (INS) to ascertain their position during flight. INS utilises precise instruments, such as gyroscopes and accelerometers, to measure movement and rotation, and integrates these data to determine velocity and position. This method remains effective even when external signals are obstructed, such as during plasma blackouts that affect radio-based systems during hypersonic travel (SIPRI, 2022). Ring Laser Gyroscopes (RLGs) and Fiber Optic Gyroscopes (FOGs) are essential for detecting rotation in these scenarios. They exhibit remarkable stability, with errors as minimal as 0.001 deg per hour, thereby facilitating accurate weapon targeting. Accelerometers, such as those composed of quartz and silicon, measure linear motion with exceptional precision (Pugwash Foundation, 2020).
GPS Integration and Plasma Effects
The integration of the Global Positioning System (GPS) enhances navigation accuracy when signals are accessible. However, the plasma layer surrounding hypersonic vehicles can obstruct GPS signals; this plasma consists of charged air particles and free electrons that attenuate signals, particularly those below a specific frequency (Defence Technical Information Center, 2005). Recent research indicates that modifying vehicle shapes and employing specialised materials can mitigate plasma effects, enabling GPS signal penetration. Additionally, robust antennas and advanced signal processing facilitate signal reception during partial blackouts. The combination of GPS with INS using Kalman filtering maintains navigation accuracy even when GPS is intermittently available (Genesys Defence, 2025).
Onboard Computing Architectures
Hypersonic weapons encounter challenging conditions that constrain onboard computing systems. Temperatures can exceed 200 °C, and the high forces experienced during manoeuvres necessitate specialised hardware. Radiation-resistant processors, high-temperature electronics, and durable packaging provide the requisite computing power for guidance and control (Pugwash Foundation 2020). The application of neural networks represents a novel approach for enhancing guidance and flight control. Machine learning can adapt to unforeseen conditions and optimise trajectories in real time to extend the range, reduce thermal loads, or evade defences. These strategies leverage the increasing computational capabilities of aerospace systems (SIPRI 2022).
Target Detection, Acquisition, and Attack Sensor Systems and Seeker Technologies
For terminal guidance, hypersonic weapons employ multiple sensors to identify targets despite their defences and obstacles. Radio Frequency (RF) seekers, such as radars, operate under all weather conditions and possess long ranges. However, plasma effects can degrade the RF sensor performance during high-speed flight (Genesys Defence, 2025). Infrared (IR) seekers offer precision and resistance to electronic interference; however, they encounter challenges from the heat of the vehicle and atmospheric effects. Advanced seekers utilize multiple IR wavelengths to differentiate targets from complex backgrounds. The integration of RF and IR sensors with fusion algorithms enhances the system performance and reliability (Raytheon, 2024).
Kill Chain Dynamics
The deployment of hypersonic weapons encompasses several critical stages, including detection, tracking, targeting, engagement, and outcome assessment. These stages are executed within minutes because the rapid velocity of hypersonic systems necessitates expedited decision-making and advanced control mechanisms (Joint Advanced Warfighting School 2023). Prior to launch, intelligence and surveillance operations identify target locations and assess the defensive measures. Planning systems then determine the optimal flight trajectories, considering potential threats and terrain features. During flight, hypersonic weapons adhere to predetermined paths but can be adjusted based on updated targeting information (Northrop Grumman, 2026). In the terminal phase of the attack, these weapons employ sharp manoeuvres to evade defences and achieve precise target engagement. Hypersonic glide vehicles (HGVs) can move laterally over extensive distances, rendering them unpredictable and challenging to intercept. Their velocity and manoeuvrability significantly complicate defensive efforts (Wikipedia 2025).
Warhead Design and Explosive Effectiveness
Conventional Warhead Configurations
Hypersonic weapon warheads leverage high-speed impacts to enhance their destructive potential. At velocities exceeding Mach 5, the kinetic impact can surpass the efficacy of traditional explosives, allowing for reduced explosive payloads while maintaining their effectiveness. This capability facilitates the penetration of fortified targets and minimises collateral damage compared to slower weapon systems (Congressional Budget Office, 2023). Penetrator warheads are engineered with robust casings and specialised geometries to engage subterranean and reinforced targets. Hypersonic speeds enable penetration depths exceeding 10 m in concrete. Blast-fragmentation warheads are optimised for extensive area effects on soft targets, utilising high-speed impact to amplify the blast pressure (Defence Security Monitor, 2025).
Nano energetic materials (nEMs) are revolutionising the capabilities of hypersonic warheads by employing ultrafine fuel and oxidiser powders. These materials enhance the reactive surface area, resulting in much higher energy densities and faster reaction rates compared to traditional explosives. This allows substantial structural damage without increasing the payload weight or size. Key Advantages of nEMs in Hypersonic Warheads:
Mass-to-Destruction Multiplier: Hypersonic missiles depend on immense kinetic energy to breach heavily fortified targets, making warhead space and weight critical constraints in their design. nEMs offer explosive power that far surpasses that of conventional materials within the same volume.
Tailored Reaction Rates: The combustion efficiency and energy release rate of nEMs can be adjusted at the molecular level. This enables warheads to decide whether to deliver explosive energy as a rapid, high-pressure shock wave for deep penetration or as prolonged heat and gas for maximum incendiary impact.
Enhanced Insensitivity: Despite their high reactivity, many nEM composites show reduced mechanical sensitivity, meaning they are less likely to accidentally detonate owing to friction, impact, or the intense aerodynamic vibrations of Mach 5+ flight compared with traditional microsized formulations.
Operational Applications
Kinetic Energy Penetrators: Incorporating nEMs into the tips of kinetic energy penetrators allows the warhead to pierce through hardened bunkers before detonation, creating a combined kinetic and chemical breach.
Reactive Material (RM) Warheads: When hypersonic fragments or fragments infused with nEMs hit a target, the impact triggers an intense, localised energy release. This transforms kinetic fragmentation into extremely hot incendiary reactions capable of destroying unarmoured vehicles or detonating secondary fuel or ammunition supplies within the target.
Miniaturised Initiation: The high surface-to-volume ratio of nEMs is crucial for micro-electro-explosive devices (MEEDs), enabling the safe, precise, and instantaneous initiation of complex multi-stage warheads.
Nuclear Warhead Integration
Russia and China are integrating nuclear warheads with hypersonic systems, thereby altering their strategic implications. The Russian Avangard HGV, equipped with a 2-megaton nuclear warhead, can achieve speeds of Mach 20, circumvent existing missile defences while traversing vast distances (National Institute for Defence Studies 2024). The dual capability to carry both conventional and nuclear warheads introduces ambiguity, complicating the identification of the warhead type in flight. This ambiguity reduces decision-making timeframes and increases the risk of inadvertent conflict. Such uncertainty poses significant challenges to arms control and strategic stability (Congressional Research Service 2025).
Country-Wise Development Status
United States
The United States is advancing hypersonic weapon development in its various military branches. The Army’s Long-Range Hypersonic Weapon (LRHW) underwent its inaugural test in December 2024, employing the Common-Hypersonic Glide Body (C-HGB) with a two-stage booster. The Navy’s Conventional Prompt Strike (CPS) program also utilises the C-HGB and is progressing towards integration with Zumwalt-class destroyers and Virginia-class submarines (Defence Security Monitor, 2025).
The United States Air Force’s Hypersonic Attack Cruise Missile (HACM) initiative, awarded to Raytheon, is projected to become operational by 2027. This project employs scramjet engines to facilitate rapid deployment from aircraft, distinguishing it from the AGM-183A Air-Launched Rapid Response Weapon (ARRW), which has encountered developmental challenges (Popular Mechanics 2026). Concurrently, the Defence Advanced Research Projects Agency (DARPA) is advancing hypersonic technology through initiatives such as the Hypersonic Air-breathing Weapon Concept (HAWC) and Tactical Boost Glide (TBG), which emphasise scramjet propulsion, thermal protection, and guidance systems for hypersonic vehicles. The fiscal year 2026 budget allocates approximately $2.1 billion to hypersonic projects, underscoring their strategic significance (Forecast International, 2025).
Russia
Russia possesses several advanced hypersonic systems. The Avangard Hypersonic Glide Vehicle (HGV), deployed on SS-19 Intercontinental Ballistic Missiles (ICBMs), became operational in December 2019 with the 13th Guards Rocket Division at Dombarovsky. Russia claims that Avangard can achieve speeds of Mach 20 and evade missile-defence systems (National Institute for Defence Studies, 2024). The 3M22 Zircon (Tsirkon) missile exemplifies Russia’s scramjet capabilities, reaching speeds of Mach 9 and ranges exceeding 1,000 km. Tests conducted between 2021 and 2022 demonstrated its sea-launch capabilities. President Putin announced the induction of Zircon into the Navy in July 2022, although its current operational status remains uncertain (National Institute for Defence Studies 2024). The Kinzhal (Dagger) missile, although not a true hypersonic glide vehicle, attains hypersonic speeds during its terminal phase and has been deployed in Ukraine, providing empirical data on hypersonic weaponry and defence systems (WION, 2025).
China
China is recognised as a leader in hypersonic technology, demonstrated by the DF-17 missile, which carries the DF-ZF glide vehicle, which was showcased during the 2019 military parade. The DF-ZF can reach speeds between Mach 5 and 10 and circumvent regional defence systems, with a range of 1,800 to 2,500 km, targeting areas such as Taiwan, Japan, and South Korea (Jamestown Foundation, 2016). China’s hypersonic test in August 2021, which involved a Fractional Orbital Bombardment System (FOBS) and a glide vehicle, raised significant concerns owing to its demonstrated capability to strike the United States from the southern hemisphere, thereby bypassing the northern defence systems. General Mark Milley described the test as alarming and indicative of China’s rapid technological advancements (National Institute for Defence Studies, 2024). The Starry Sky-2 (Xing Kong-2) represents China’s waverider-type missile, achieving Mach 6 in tests. China’s hypersonic program encompasses glide vehicles, cruise missiles, and supporting technologies, such as wind tunnels (AIVON, 2025).
Other Nations
India is advancing the development of a Hypersonic Technology Demonstrator Vehicle (HSTDV) in collaboration with the Defence Research and Development Organisation (DRDO). Successful tests conducted in 2020 and 2023 demonstrated the effective operation of scramjet engines. Additionally, India is collaborating with Russia on hypersonic cruise missiles while simultaneously enhancing its capabilities (WION, 2025).
France’s V-max program conducted its inaugural flight test in June 2023 to gather data for future advancements, underscoring the significance of hypersonic technology in its defence strategy. In July 2023, the United Kingdom established a dedicated department for hypersonic technology, with plans to allocate contracts worth up to GBP 1 billion over seven years (AIVON, 2025).
Australia is partnering with the United States in the SCIFiRE program and leveraging its robust aerospace research expertise.
Japan’s HVGP program aims to achieve operational readiness by 2030 to safeguard its remote islands.
North Korea claims to have tested hypersonic missiles, although Western experts are sceptical about their full capabilities (WION, 2025).
Testing and Evaluation of Hypersonic Weapons
The development of hypersonic weapons necessitates extensive testing, which is challenging because of the extreme conditions involved. Ground test facilities, such as wind tunnels, aid but cannot fully replicate real flight conditions, as they offer only short test durations, which limits long-duration flight testing (Johns Hopkins APL, 2005). Flight tests are essential but entail significant expenses and complexity, requiring extensive preparation, including safety checks and data collection. Initial tests often encounter failures, as evidenced by the U.S. X-51A program, which achieved approximately 50% success, compared to China’s DF-ZF, which attained about 83% success (Jamestown Foundation, 2016).
Computer modelling and simulation are increasingly pivotal in hypersonic development, enabling virtual testing prior to expensive flight tests. Advances in simulation tools have enhanced engineers’ ability to predict performance; however, the intricate nature of hypersonic flows continues to challenge these tools (Patsnap Eureka, 2025). Model-based systems engineering is employed to manage the complexity of hypersonic weapon development, facilitating the integration of subsystems and optimising performance prior to physical testing. The Mayhem program, led by Leidos with support from Draper Laboratory and the University of Michigan, utilises virtual ecosystems for hypersonic designs (AIVON, 2025).
Cost Considerations and Industrial Base
The development and procurement of hypersonic weapons entail significant financial expenditure, influencing program planning and military organizational structures. According to the Congressional Budget Office, the cost of each hypersonic weapon system ranges from $10 million to $30 million, depending on its design and production volume. These costs exceed those of conventional cruise missiles, which are priced between $1 million and $3 million. Nonetheless, hypersonic weapons possess unique capabilities that conventional systems lack (Congressional Budget Office 2023). The hypersonic industry requires specialised expertise in high-temperature materials, precision manufacturing, advanced propulsion systems, and system integration. Sustaining this industry requires ongoing investment in research, testing, and workforce training. Over time, the number of companies capable of managing hypersonic programs has diminished, potentially leading to production delays (Congressional Research Service 2025). International collaboration can facilitate cost- and risk-sharing and expedite development. The United States and Japan are collaborating on the Glide Phase Interceptor, with Japan concentrating on engine development and the United States focusing on system integration and technology. Similar partnerships with Australia, the United Kingdom, and other nations are under consideration to leverage each country’s strengths and distribute the development responsibilities (Raytheon, 2024).
Future Developments
The field of hypersonic weapons is rapidly evolving, with emerging trends shaping their future trajectory. Rotating Detonation Engine (RDE) technology has the potential to enhance the fuel efficiency and power of hypersonic missiles. DARPA’s Gambit program, led by Raytheon, is investigating RDE for air-launched weapons, which could result in smaller and more advanced hypersonic weapons (AIVON, 2025). The U.S. The Air Force’s ARMD program, which utilises Ursa Major’s Draper engine, aims to produce cost-effective, liquid-fuelled hypersonic missiles expeditiously. The Draper engine combines the storage advantages of solid fuels with the control offered by liquid systems, thereby providing flexibility. Brigadier General Jason Bartolomei of AFRL described this program as “a new path towards a cost-effective, mass-producible deterrent for the nation” (Popular Mechanics, 2026). Space-based hypersonic systems may emerge as future options with significant strategic implications. Hypersonic Glide Vehicles (HGVs) in Low Earth Orbit could enable global strikes without the conventional warnings associated with missile launches. Although these systems would contravene existing space weapon treaties, they present strategic challenges. China’s 2021 test of the Fractional Orbital Bombardment System (FOBS) indicates that space-based hypersonic concepts are under exploration (Joint Advanced Warfighting School, 2023).
Hypersonic defence systems
Advancements in hypersonic defence systems are progressing in tandem with the development of offensive capabilities. The Glide Phase Interceptor (GPI), currently under development by Raytheon and Northrop Grumman in collaboration with Japan, is designed to target hypersonic weapons during their most vulnerable phases. Space-based sensors, such as the Hypersonic and Ballistic Tracking Space Sensor (HBTSS), are intended to monitor hypersonic threats throughout their trajectory. These defensive measures are anticipated to influence the efficacy of hypersonic weapons (Raytheon 2024). Emerging technologies, including artificial intelligence, quantum sensing, and directed energy, have the potential to transform hypersonic weapons and their defences. Artificial intelligence systems may enhance target identification and engagement, whereas quantum sensors can offer navigation solutions that are resistant to jamming. Directed energy weapons present a potentially cost-effective defence against hypersonic threats, although they continue to encounter technical challenges (Loop, 2025).
Hypersonic Weapons and Strategic Stability
Hypersonic weapons hold significant importance in contemporary warfare, impacting deterrence strategies by reducing decision-making time and challenging existing defences. Their speed and agility enable rapid target engagement, providing capabilities that were previously exclusive to nuclear weapons (Joint Advanced Warfighting School, 2023). The influence of hypersonic weapons on strategic stability remains debatable. Some argue that they provide credible deterrence below the nuclear threshold, thereby enhancing the stability of crises. Conversely, others contend that ambiguous warheads and compressed timelines may elevate these risks (The Loop, 2025). The Atlantic Council posits that hypersonic weapons introduce uncertainty into deterrence dynamics, potentially prompting pre-emptive actions during crises. Their velocity may embolden adversaries to consider non-nuclear strikes, thereby affecting political decisions and heightening the risk of conflict (Joint Advanced Warfighting School 2023). Hypersonic weapons fulfil dual roles within Anti-Access/Area Denial (A2/AD) strategies, both reinforcing one’s own denial capabilities and facilitating the penetration of enemy zones. For nations such as China and Russia, hypersonic systems complicate U.S. power projection by threatening critical assets, including aircraft carriers and military bases. Conversely, U.S. hypersonic capabilities can counteract adversarial A2/AD systems (Congressional Budget Office, 2023). Russian General Valery Gerasimov’s doctrine emphasises “long-distance, contactless actions” to achieve strategic objectives in warfare. Hypersonic systems are integral to Russia’s non-nuclear deterrence strategy, which aims to avoid large-scale confrontations while achieving strategic effects through precise strikes (Joint Advanced Warfighting School, 2023).
Impact on Alliances
The proliferation of hypersonic weapons poses significant challenges to the United States’ commitment to safeguarding its allies. Nations possessing these weapons have the capability to threaten U.S. forces and allied nations, thereby casting doubt on U.S. security assurances. This situation has prompted allies such as Japan, Australia, and European countries to pursue the development of their own hypersonic weapons (Militaire Spectator, 2020). In response, alliances are collaborating on initiatives such as the US–Japan GPI partnership and sharing intelligence for early warning systems. NATO’s strategic plans now incorporate hypersonic threats, underscoring their increasing significance. However, integrating hypersonic defence into security strategies remains a complex task (Raytheon, 2024). The challenges of integration include the following aspects:
– Radar and Horizon Constraints: Hypersonic Glide Vehicles (HGVs) operate at significantly lower altitudes than conventional ballistic missiles. Consequently, they remain below the detection range of traditional ground-based radar systems until shortly before they strike.
– Plasma Disruption: The intense speeds generate a plasma sheath around the vehicle, posing technical difficulties for onboard navigation and maintaining real-time communication with the missile.
– Constellation Needs: To counteract this, continuous 360-degree monitoring is essential, prompting defence agencies to invest in costly space-based sensor networks, such as the United States’ hypersonic and ballistic tracking space sensor (HBTSS) initiatives.
– Manoeuvrability: Unlike the predictable paths of ballistic missiles, hypersonic weapons can change their course, complicating the calculation of interception points during flight and rendering space-based defence systems ineffective.
– Cost-Exchange Imbalance: The expense of developing and deploying sophisticated interceptors far exceeds the cost of hypersonic threats. Protecting large areas with interceptors is financially impractical, leading militaries to focus on strategically fortified “point defence” zones.
At the tactical level, hypersonic weapons provide commanders with the capability to engage critical targets rapidly. These weapons can strike within minutes, targeting mobile assets, command centres, and essential infrastructure before adversaries can respond to them. This capability is particularly advantageous against anti-access systems, command hubs, and locations housing weapons of mass destruction (Joint Advanced Warfighting School 2023). However, these weapons also complicate force protection and logistical management. The rapidity of attacks reduces the time available for defensive preparations, rendering bases and ports more susceptible to threats. Consequently, there is a need for enhanced defensive measures and improved protection systems. The threat to aircraft carriers has necessitated adjustments to naval strategies (Congressional Budget Office, 2023).
The emergence of hypersonic weapons has compelled naval forces to transition from close-range power projection to “standoff” operations. To ensure survival, strike groups disperse their formations, emphasise long-range capabilities, and employ AI-enhanced early warning systems, depending on speed and layered kinetic and directed-energy defence strategies. These changes are categorised into the following areas.
– Extended Strike Distances: Carrier aircraft operate farther offshore to stay beyond the reach of land-based hypersonic missiles’ Anti-Access/Area Denial (A2/AD) zones.
– Autonomous Refuelling: The use of unmanned platforms, such as the carrier-launched MQ-25 Stingray, provides mid-air refuelling for strike aircraft, enabling carriers to project air power from safer standoff distances.
– Over-the-Horizon Detection: Navies are incorporating space-based infrared satellite constellations (such as the US Space Development Agency’s tracking layers) and airborne sensors to immediately detect hypersonic launches and track their changing trajectories.
– Coordinated Command and Control: Distributed sensor networks, such as the Naval Integrated Fire Control-Counter Air (NIFC-CA), link various ships, and aircraft, allowing interceptors to engage targets beyond the radar range of the launching ship.
– Decentralised Formations: Instead of operating in tightly grouped, heavily protected formations, Carrier Strike Groups (CSGs) are increasingly using dispersed formations. This complicates enemy targeting, making it challenging to locate high-value assets in real time.
– Offensive Strategy: Focus is shifting towards offensive “left-of-launch” deterrence, which neutralises enemy missile sites, launch platforms, and command nodes through cyber, electronic warfare, or pre-emptive strikes.
– Terminal Interception: The U.S. The Navy and allied forces are concentrating on terminal-phase interception with systems such as the SM-6 missile, which are updated to track and engage highly manoeuvrable threats in their terminal moments of flight.
– Directed Energy: Given the extremely short reaction times for hypersonic weapons, navies are testing and deploying Directed Energy Weapons (DEWs), such as high-energy shipboard lasers, to disrupt or destroy incoming threats.
The employment of hypersonic weapons in joint operations necessitates the development of new tactics and coordination among intelligence, command systems, and strike platforms. The rules of engagement must be adapted to accommodate swift decision-making and the potential for rapid escalation (Joint Advanced Warfighting School, 2023).
Hypersonic Weapons and International Arms Control Frameworks
The rapid advancement of hypersonic weapons has outpaced international arms control frameworks, resulting in security breaches. The 1987 Missile Technology Control Regime (MTCR) was not designed to address hypersonic systems, focusing instead on ballistic and cruise missiles. This leaves the regulatory framework for HGVs and HCMs ambiguous (SIPRI 2022). The New START treaty between the U.S. and Russia does not encompass hypersonic weapons, creating a regulatory loophole. While it imposes limits on ballistic missile launchers and warheads, it may not fully account for hypersonic glide vehicles on intercontinental ballistic missiles (ICBMs). This undermines the treaty’s control over strategic systems and highlights the necessity for updated arms control measures (Altrinsic, 2025).
To effectively regulate hypersonic weapons, experts advocate the revision of existing treaties to encompass these weapons, the establishment of new multilateral agreements, and the implementation of transparency measures. However, the verification of these weapons poses significant challenges because of their high velocity and the difficulty in distinguishing between nuclear and conventional warheads, complicating treaty formulation. Additionally, geopolitical competition among major powers renders swift agreements improbable (Congressional Research Service 2025).
Conclusion
Hypersonic missiles and glide vehicles are revolutionizing military technology, influencing global security and military strategy. Technological challenges, such as heat management and navigation, have been addressed, transitioning these weapons from experimental stages to operational capabilities. Russia and China are at the forefront of deploying these weapons, while the United States is actively developing its arsenal. Countries such as India, France, and Japan are also engaging in this domain, which has implications for regional security and global stability. The impact of hypersonic weapons extends beyond military applications and affects deterrence, crisis stability, and alliances. The rapid decision-making required, uncertainty regarding warhead types, and inadequate defences present risks that necessitate careful consideration by policymakers. Current arms control agreements have not kept pace with these advancements, resulting in gaps that require renewed diplomatic initiatives. Future advancements in hypersonic technology, including enhanced propulsion systems and space-based platforms, will continue to reshape the strategic landscape of military operations. The integration of these weapons into military strategies signifies a long-term transformation of warfare. A comprehensive understanding of their technical specifications and strategic implications is crucial for formulating defence policies and ensuring global security. As the proliferation of these weapons continues, the international community must manage the associated risks while harnessing their potential to enhance stability.
