Sindhughosh-class submarines are Kilo-class diesel-electric submarines in active service with the Indian Navy. Their names are in Sanskrit, but in their Roman-alphabet forms sometimes a final short -a is dropped.

The Sindhughosh submarines, designated 877EKM, were designed as part of Project 877, and built under a contract between Rosvooruzhenie and the Ministry of Defence (India).

The submarines have a displacement of 3,000 tonnes, a maximum diving depth of 300 meters, top speed of 18 knots, and are able to operate solo for 45 days with a crew of 53. The final unit was the first to be equipped with the 3M-54 Klub (SS-N-27) antiship cruise missiles with a range of 220 km.

Incidents

On 10 January 2008, the INS Sindhughosh collided with cargo ship MV Leeds Castle. The submarine is reported to have sustained superficial damage to its conning tower. As a result, the submarine was out of service for a month. The cargo ship was in restricted shallow waters.

On 26 February 2010, a fire on board INS Sindhurakshak killed one sailor and injured two others. The fire was due to a defective battery. On 14 August 2013 an explosion, followed by a fire, was reported to have occurred on the Sindhurakshak. The Sindhurakshak sank in the dock.

INS Sindhuvijay has been upgraded with the hydro acoustical USHUS complex and the CCS-MK radio communications system.
