SMART SYSTEM (Syllabus: GS Paper 3 – Sci and Tech)

Context: DRDO successfully flight tested the Supersonic Missile-Assisted Release of Torpedo (SMART) system from Dr APJ Abdul Kalam Island off the coast of Odisha.

Supersonic Missile Assisted Release of Torpedo (SMART)

• Developed by: The Defence Research and Development Organization (DRDO) engineered the SMART for the Indian Navy.
• Objective: To bolster the Indian Navy's anti-submarine warfare capabilities, extending beyond the typical range of lightweight torpedoes.
• Features

o The missile boasts a two-stage solid propulsion system, electromechanical actuator system, and precision inertial navigation system.

o Launch Capabilities: The SMART system can be deployed from surface ships or truck-based coastal batteries, ensuring versatility in launch platforms.

o Propellant Composition: Fueled by solid propellant and powered by a silver zinc battery, the SMART is engineered for efficiency and reliability.

o Range: 643 km, the SMART can carry a lightweight torpedo equipped with a 50 kg high explosive warhead up to 20 km.

o Acoustic Homing: Utilizing acoustic signals from the target, the SMART employs acoustic homing to guide itself effectively to its destination.

o Guidance System: Armed with an inertial navigation system (INS), the SMART offers real-time course corrections and target updates via datalink.
