The supersonic missile assisted release of torpedo (SMART) test was successfully carried out in flight by the Defence Research and Development Organization (DRDO).
What is SMART?
A lightweight torpedo delivery system based on next-generation missiles is called SMART (Supersonic Missile Assisted Release of Torpedo).
The missile system consists of: o a lightweight torpedo with a 20 km range; o a long-range supersonic missile carrier with a maximum speed of 643 kph; and o a payload of a 50 kg high explosive warhead.
The missile has a two-stage solid propulsion system, precise inertial navigation, electromechanical actuators, and a datalink for torpedo terminal homing and mid-course upgrades.
