Maareech ATDS

Maareech Advanced Torpedo Defence System (ATDS) is a torpedo detection and countermeasure system used by the Indian Navy. The system offers a complete solution to detect and locate an incoming torpedo and to apply countermeasures to protect naval platform against torpedo attack. It was developed as a joint project of the Naval Physical and Oceanographic Laboratory (NPOL), Kochi and the Naval Science and Technological Laboratory (NSTL), Visakhapatnam.[1][2][3] [4]

It is an anti-torpedo system with towed and expendable decoys. The system is capable of detecting, confusing, diverting and decoying the incoming torpedoes. The decoy helps in exhausting the energy of the torpedo by running the later through long and ineffective course and prevents them from homing in to the targeted platform with its advanced counter-measure capabilities.

Two production grade MAAREECH systems have been developed and user evaluation trials completed on board two Indian Navy ships.[1]

The Indian Navy has already placed orders for three torpedo defence systems that would be installed on ships at the Mazagon Dock Limited.
