Indian Navy Successfully Tests NASM-SR Missile with In-Flight Retargeting Capability

The Indian Navy and the Defence Research & Development Organisation (DRDO) achieved a significant milestone on February 25, 2025, by successfully conducting flight trials of the Naval Anti-Ship Missile – Short Range (NASM-SR) from the Integrated Test Range (ITR), Chandipur. This cutting-edge missile was launched from an Indian Naval Sea King helicopter, showcasing its advanced capabilities against ship targets.

What makes the NASM-SR stand out is its Man-in-Loop feature, allowing pilots to retarget in mid-flight. During the trial, the missile locked onto a large ship-sized target but was later redirected to strike a smaller, concealed target with pinpoint precision. This real-time decision-making ability is made possible through a high-bandwidth two-way data link, transmitting live seeker images back to the pilot.

The missile employs an Indigenous Imaging Infra-Red Seeker for terminal guidance, ensuring high accuracy in engagements. It also incorporates a Fiber Optic Gyroscope-based Inertial Navigation System (INS), a radio altimeter for mid-course guidance, electro-mechanical actuators for aerodynamic and jet vane control, and an integrated avionics module. Additionally, it features solid propulsion with an in-line ejectable booster and a long-burn sustainer, providing optimal speed and range.

Developed by multiple DRDO laboratories, including the Research Centre Imarat, Defence Research and Development Laboratory, High Energy Materials Research Laboratory, and Terminal Ballistics Research Laboratory, the NASM-SR represents a major leap in India’s indigenous missile technology. The production of these missiles is being carried out by Development cum Production Partners (DcPP) with contributions from MSMEs, start-ups, and other industrial partners.

The successful test has drawn praise from Defence Minister Rajnath Singh, who highlighted the game-changing in-flight retargeting capability that significantly enhances operational flexibility. DRDO Chairman Dr. Samir V. Kamat also congratulated the DRDO team, the Indian Navy, and industry partners for their contributions to the successful demonstration.

This achievement reinforces India’s commitment to developing next-generation indigenous defence technologies, strengthening the Navy’s firepower and operational readiness in maritime warfare.
