Recently, the Defence Research and Development Organisation (DRDO) and the Indian Navy successfully conducted flight trials of the Naval Anti-Ship Missile Short Range (NASM-SR) at the Integrated Test Range in Chandipur, Odisha. This milestone marks a significant advancement in India’s defence capabilities. The trials highlighted the missile’s cutting-edge features, particularly its “Man-in-Loop” capability, allowing in-flight retargeting for greater operational flexibility.
Advanced Missile Specifications and Features
The NASM-SR missile incorporates an indigenous Imaging Infra-Red (IIR) seeker for terminal guidance, ensuring precise target engagement. Additionally, it boasts a high-bandwidth two-way datalink system, transmitting real-time images back to the pilot, enabling dynamic mid-flight target selection.
Launch and Target Engagement
During the test, the missile was launched from an Indian Naval Seaking helicopter. Initially, it locked onto a large target within a designated search area. In the terminal phase, the pilot retargeted it to a smaller concealed target. This demonstrated the missile’s ability to accurately strike targets in sea-skimming mode at maximum range.
Guidance and Navigation Systems
The NASM-SR integrates a Fiber Optic Gyroscope-based Inertial Navigation System (INS) and a Radio Altimeter for mid-course guidance. It also features an advanced avionics module and electro-mechanical actuators for enhanced control. The missile is powered by a solid propulsion system, which includes an in-line ejectable booster and a long-burn sustainer, ensuring optimal range and efficiency.
Development and Production
The NASM-SR is developed through collaboration between various DRDO laboratories, including the Research Centre Imarat and the Defence Research and Development Laboratory. The production process involves partnerships with micro, medium, and small enterprises (MSMEs) and startups, underlining India’s commitment to self-reliance in defence manufacturing.
Strategic Significance of the Trials
Defence Minister Rajnath Singh lauded the successful trials, emphasizing the game-changing “Man-in-Loop” feature, which enhances operational effectiveness by allowing real-time adjustments during a mission. These successful trials not only demonstrate the missile’s technical prowess but also significantly bolster India’s maritime defence strategy, reinforcing its capability to counter emerging threats effectively.
