DRDO and Indian Navy Successfully Test Indigenous Anti-Ship Missile
On February 25, 2025, the Defence Research & Development Organisation (DRDO) and the Indian Navy conducted successful flight trials of a pioneering Naval Anti-Ship Missile (NASM-SR) at the Integrated Test Range (ITR) in Chandipur. This test showcased the missile’s capability to engage ship targets when launched from an Indian Naval Seaking helicopter.
Successful Flight Trials of Anti-Ship Missile
The trials validated the missile’s “Man-in-Loop” feature, achieving a direct hit on a small ship target in sea-skimming mode at its maximum range. The missile employs an indigenous Imaging Infra-Red Seeker for terminal guidance. Additionally, the mission demonstrated a high-bandwidth two-way datalink system, enabling the transmission of live seeker images back to the pilot for in-flight retargeting.
Advanced Guidance and Control Systems
Launched in “Bearing-only Lock-on after launch” mode amidst multiple nearby targets, the missile initially locked onto a larger target within a designated search zone. During the terminal phase, the pilot selected a smaller, concealed target, resulting in a precise strike. The missile’s mid-course guidance is facilitated by an indigenous Fiber Optic Gyroscope-based Inertial Navigation System (INS) and a Radio Altimeter. It also features an integrated avionics module, electro-mechanical actuators for aerodynamic and jet vane control, thermal batteries, and a PCB warhead. Propulsion is provided by a solid system with an in-line ejectable booster and a long-burn sustainer.
Collaborative Development Efforts
The missile’s development involved multiple DRDO laboratories, including the Research Centre Imarat, Defence Research and Development Laboratory, High Energy Materials Research Laboratory, and Terminal Ballistics Research Laboratory. Production is currently underway through Development cum Production Partners, with contributions from MSMEs, start-ups, and other industry collaborators.
Defence Minister Rajnath Singh lauded DRDO, the Indian Navy, and industry partners for the successful tests, highlighting the uniqueness of the “Man-in-Loop” feature, which allows for in-flight retargeting. Dr. Samir V. Kamat, Secretary of the Department of Defence R&D and Chairman of DRDO, also commended the collective efforts of the DRDO team, users, and industry partners in achieving this milestone.
This successful trial signifies a significant advancement in India’s indigenous defense capabilities, particularly in enhancing the Indian Navy’s operational flexibility and precision in maritime engagements.
