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.
