Its main function is the research and development of underwater weapons and associated systems.
[1] NSTL was established on 20 August 1969 to undertake research and development of major naval systems and underwater weapons for the Indian Navy to make it self-reliant.
[2] These include torpedoes, mines, decoys, targets, simulators, Fire Control Systems and weapon launchers.
The lab is also involved in investigating hydrodynamic parameters and structural design of surface and submerged naval platforms and in evolving design criteria through model studies and simulation.
NSTL also develops specialized materials for Marine Applications, including materials for mitigation of Radar, IR, Magnetic, Acoustic and ELFE Signatures leading to stealthier platforms.
