Indian Navy's Hypersonic Strike Capability Set to Triple with Long-Range Missile Upgrade

India's LR-AShM Programme Takes a Giant Leap Forward

The Defence Research and Development Organisation (DRDO) is reportedly working on a long-range variant of the Long Range Anti-Ship Missile (LR-AShM), which could potentially strike aircraft carriers up to 3,500 km away. This significant upgrade would transform the missile's role, extending its use beyond traditional coastal anti-ship operations to include a strategic long-range maritime strike capability.

The proposed upgrade is expected to be based on the LR-AShM's current boost-glide design, which is a hypersonic system being developed for the Indian Navy. The system is designed to give the Navy the ability to engage targets at long range from a maritime position, making it an invaluable asset for the country's maritime strike capabilities.

However, increasing the range of the LR-AShM to 3,500 km would require significant modifications to the missile's propulsion system, aerodynamic shape, thermal protection, guidance system, and flight profile. The booster would need to provide the hypersonic glide vehicle with enough initial speed and altitude to complete the extended-range flight path. This could be achieved by using higher-energy solid propulsion and optimising the boost phase.

• Key Challenges Ahead
• Thermal Management: The hypersonic glide vehicle would need to be protected from serious aerodynamic heating, which could be achieved through advanced thermal-protection materials, better high-temperature structures, and aerodynamic optimisation.
• Navigation: The system would need to use a highly resilient navigation architecture that combines accurate inertial navigation with assistance from satellite navigation and possibly other autonomous navigation methods.
• Electronic Warfare: The system would need to be capable of carrying out its mission even in difficult electronic-warfare situations.

The development of a 3,500-km range LR-AShM would have significant strategic consequences for India. It would enable the country to place distant maritime areas at risk from launch sites on land, resulting in a wider anti-access/area-denial zone around the Indian coastline and its strategically important island territories. The system could also be used to supplement rather than replace existing systems such as BrahMos, which offers a mature capability for supersonic cruise missiles.

• Potential Applications
• Maritime Strike Capabilities: The long-range LR-AShM could provide a hypersonic boost-glide option with a much greater range, making it more difficult for an adversary to predict and defend against India's maritime strike capabilities.
• Distributed Maritime Strike Network: The system could be used to establish a distributed maritime strike network, which would enable the Indian Navy to keep hostile surface forces at a distance.

While the 3,500-km range mentioned is a development goal, not an officially confirmed operational specification, the programme has the potential to be one of India's most important future developments in long-range missiles. The Indian Navy's emphasis on keeping hostile surface forces at a distance and establishing a distributed maritime strike network makes the development of a long-range LR-AShM a crucial step forward in enhancing the country's maritime strike capabilities.
