German advanced systems firm Atlas Elektronik has been selected by the Indian Navy to upgrade 64 German-built AEG SUT-66 Mod.1 heavyweight torpedoes deployed on the HDW Class 209 submarines, each of which has a capacity for 14 such weapons. The upgrade programme will essentially extend the life of the torpedoes by at least 15-17 years. The Indian Navy has selected the WASS BlackShark heavy torpedoes for its Scorpene submarines, a prospective deal in which Atlas Elektronik was defeated, though the company remains bullish on the Indian market, with expected wins in contracts for active towed array sonars (ATAS) for frontline Indian warships, as well as other crucial weapons programmes that remain to be defined formally by Naval HQ. Other equipment Atlas will be looking to pitch to India include submarine systems, mine counter measures and advanced combat systems for ships and submarines.
