India has achieved a significant milestone in its defence capabilities with the successful flight test of its first helicopter-launched anti-ship missile. Developed by the Defence Research and Development Organisation (DRDO) in collaboration with the Indian Navy, the Naval Anti-Ship missile (short-range), or NASM-SR, was launched from a Sea King helicopter and successfully struck a designated ship target.
According to a statement from the Indian Ministry of Defence (MoD), the missile was employed in a “bearing-only lock-on after launch” mode. This innovative approach involved multiple targets in proximity, allowing the pilot to select the most suitable one for engagement after launch. The missile initially locked onto a larger target within its search zone. However, during the terminal phase, the pilot was able to switch focus to a smaller, concealed target, resulting in a direct hit with remarkable precision.
The NASM-SR is equipped with advanced features that enhance its operational effectiveness. For terminal guidance, the missile utilizes an imaging infrared seeker, offering resistance against radar jamming tactics. Furthermore, it has a two-way data link that allows for inflight retargeting, showcasing its adaptability in combat scenarios.
The missile incorporates a range of indigenous technologies, including a fiber optic gyroscope-based inertial navigation system (INS) and a radio altimeter for mid-course guidance. Its integrated avionics module, along with electro-mechanical actuators, ensure effective aerodynamic and jet vane control. Additionally, the missile is powered by a solid propulsion system, featuring an in-line ejectable booster and a long-burning sustainer, enabling it to fly in a sea-skimming mode. This characteristic significantly complicates interception efforts by enemy defenses.
While the NASM-SR is notable for its features, it is important to contextualize its capabilities within India’s current arsenal. The country currently lacks any air-launched anti-ship missile systems, particularly as the airborne variant of the BrahMos missile is still not operational. The NASM-SR, with a speed of Mach 0.8, is considerably slower compared to the BrahMos, which can reach speeds of Mach 2.8. Furthermore, the range of the NASM-SR is reportedly about one-tenth that of the BrahMos, which boasts a striking distance of 500 kilometers (310 miles).
The NASM-SR is expected to have a warhead weighing approximately 100 kilograms (220 pounds), powerful enough to potentially sink smaller patrol boats or inflict considerable damage on larger warships. Furthermore, while initially launched from helicopters, the missile’s design allows for reconfiguration for use from land-based platforms and smaller naval vessels.
This successful test represents a significant advancement in India’s naval warfare capabilities, enhancing its deterrent posture in a rapidly evolving maritime security landscape.
