The Shishumar-class vessels are diesel-electric attack submarines, currently in active service with the Indian Navy. These submarines are a lengthier and heavier Indian variant[3] of the Type 209 submarines developed by the German yard Howaldtswerke-Deutsche Werft (HDW) under the internal designation Type 1500. The first two vessels were built by HDW at Kiel, while the remainder were built at Mazagon Dock Limited (MDL), Mumbai under a technology transfer agreement.[4] The submarines were commissioned between 1986 and 1994. These submarines have a displacement of 1660 tons when surfaced, a speed of 22 knots (41 km/h), and a complement of 40 including eight officers.

History

India signed the agreement for these submarines with HDW on 11 December 1981. The agreement called for building of two submarines in West Germany, supply of knocked-down kits for building two more submarines in MDL, training for construction and logistics services. A subsequent agreement announced in 1984 for the construction of 2 more submarines in MDL was cancelled due to economic crisis in the late 1980s.[1] The four submarines form the 10th submarine squadron based at Mumbai.[2]
