The Project 940 Lenok class (a type of salmon) (known in the West by its NATO reporting name India class) was a military submarine design of the Soviet Union. Two vessels of this class were built for the Soviet Navy; both were scrapped in the 2000s.

The submarines of this class were designed to function as mother ships for two India-class deep-submergence rescue vehicles (DSRVs), and had decompression chambers and medical facilities on board. While India-class boats were seen going to the aid of Russian submarines involved in incidents, they had also been observed working in support of Russian Spetsnaz operations.
