Anti-Submarine Warfare (ASW)

The Defence Research and Development Organisation (DRDO) has successfully test-fired a missile assisted release of lightweight anti-submarine torpedo system for Anti-Submarine Warfare (ASW), Missile Assisted Release of Torpedo (SMART) from Wheeler Island off the coast of Odisha.

Anti-submarine warfare is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, and/or destroy enemy submarines
INS Kiltan is an indigenously-built anti-submarine warfare stealth corvette.

SMART is a missile assisted release of lightweight Anti-Submarine Torpedo System for anti-submarine warfare (ASW) for operations beyond the range of torpedo
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.
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.
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Varunastra is the first indigenous state-of -the-art heavy weight ship launched anti-submarine electric torpedo

Maritime capabilities will increase– can counter China’s String of Pearls or a blockade by Pakistan
It will also help Project 28 (class of anti- submarine warship corvettes currently in service with the Indian Navy- INS Kamorta, INS Kadmatt, INS Kiltan and INS Kavaratti) and Project 75 (building six Scorpene-Class attack submarines- Kalvari, Khanderi, Karanj, Vela, Vagir and Vagsheer).
