India Tests Indigenous Naval Anti-Ship Missile in Landmark Flight Trials

The Defence Research & Development Organisation (DRDO) and the Indian Navy have successfully completed flight trials of the Naval Anti-Ship Missile (NASM-SR) at the Integrated Test Range (ITR) in Chandipur, Odisha, marking a significant milestone for India’s defense capabilities.

This first-of-its-kind missile was launched from an Indian Naval Seaking helicopter, demonstrating its operational effectiveness against maritime targets. The trials highlighted the missile's advanced "Man-in-Loop" feature, allowing for in-flight retargeting.

The missile's production is being undertaken by Development cum Production Partners, in collaboration with MSMEs, startups, and other industry partners.

During the test, the missile made a direct hit on a small ship target using sea-skimming mode at its maximum range. It utilizes an indigenous Imaging Infra-Red (IIR) Seeker for terminal guidance, ensuring precise targeting.

A standout aspect of the mission was the successful demonstration of a high-bandwidth two-way datalink system, transmitting real-time seeker images to the pilot. This enables in-flight target selection and retargeting. The missile was launched in "Bearing-only Lock-on after Launch" mode, effectively distinguishing between multiple nearby targets.

Initially locking onto a large target within a defined search zone, the missile was later redirected by the pilot to a smaller, concealed target during the terminal phase, achieving exceptional accuracy.

The NASM-SR integrates cutting-edge indigenous technologies, including a Fiber Optic Gyroscope-based Inertial Navigation System (INS) and a Radio Altimeter for mid-course guidance. It also features an integrated avionics module, electro-mechanical actuators for aerodynamic and jet vane control, thermal batteries, and a PCB warhead. The missile is powered by a solid propulsion system with an in-line ejectable booster and a long-burn sustainer.

Developed by various DRDO laboratories, including the Research Centre Imarat, Defence Research and Development Laboratory, High Energy Materials Research Laboratory, and Terminal Ballistics Research Laboratory, the missile’s production involves Development cum Production Partners, along with MSMEs, startups, and other industry collaborators.

Defence Minister Rajnath Singh congratulated DRDO, the Indian Navy, and industry partners on the successful test, underscoring the importance of the "Man-in-Loop" feature for in-flight retargeting. Secretary of Defence R&D and DRDO Chairman Dr. Samir V. Kamat also praised the DRDO team, the Navy, and industry partners for their role in achieving this technological milestone.
