The missile releases a torpedo after reaching the target area, which can range out to 400 miles from the launch point.
India says that it has successfully tested a new supersonic anti-submarine missile. This missile carries a lightweight torpedo as its warhead and releases it over the designated target area, after which that weapon operates as normal and uses its own guidance system to seek out the enemy submarine. Dubbed the Supersonic Missile Assisted Release of Torpedo, or SMART, this could give Indian warships, and potentially shore-based units, a valuable additional stand-off tool in the face of growing submarine threats from adversaries, especially China.
The Defense Research and Development Organization (DRDO), Indian Ministry of Defense’s top research and development arm, announced the SMART test on Oct. 5, 2020. A ground-based, truck-mounted launcher was used to fire the weapon from Wheeler Island, just off the coast of northeast India in the Bay of Bengal.
