India on Monday successfully flight tested its indigenously developed Supersonic Missile Assisted Release of Torpedo (SMART) from a test range off Odisha coast, defence sources said. The trial, conducted at 1145 hrs from the APJ Abdul Kalam Island, earlier known as Wheeler Island, met all the objectives flawlessly, the sources said.

SMART is a missile assisted release of lightweight anti-submarine torpedo system for anti-submarine warfare (ASW) operations far beyond torpedo range. This launch and demonstration is significant in establishing anti-submarine warfare capabilities, a defence statement said. Defence Minister Rajnath Singh congratulated the Defence Research and Development Organisation(DRDO) scientists for the feat which marks a major breakthrough for stand-off capability in anti-submarine warfare, a DRDO official said.

The flight testing of SMART follows the successful test firing on Saturday of its indigenously developed nuclear capable hypersonic missile ‘Shaurya’ with a strike range of around 1,000 km from the test range. “All the mission objectives (of SMART) including missile flight upto the range and altitude, separation of the nose cone, release of torpedo and deployment of velocity reduction mechanism (VRM) have been met perfectly, the statement said.

Tracking stations including radars and electro optical systems along the coast and telemetry stations, including down range ships monitored all the events. A number of Defence Research and Development (DRDO) laboratories including DRDL, RCI Hyderabad, ADRDE Agra and NSTL Visakhapatnam have developed the technologies required for SMART, the sources said.

Secretary to the department of defence R&D and Chairman DRDO Dr G Satheesh Reddy, said that SMART is a game changer technology demonstration in anti-submarine warfare. The test encompasses hybrid technology which helps to upgrade the present system and also increase the striking range, the defence statement said.

SMART when launched from warship or a truck- based coastal battery, takes off like a regular supersonic missile. It covers most of its flight in the air at lower altitudes with two-way data link from the warship or an airborne submarine target detection system and provides the exact location of the hostile submarine to correct its flight path midway, it said.

Just when it approaches close enough to the submerged submarine, the missile will eject the torpedo system into the water and the autonomous torpedo will start moving towards its target to take out the submarine, it added..
