As per a 2005 cable, now on wikileaks, the submarine Rescue offered to the Indian Navy works only for HDW Sishumar class submarines. It states

Indian navy was unable to provide required technical data on Russian KILO and FOXTROT class submarines. NAVSEA efforts to perform metallurgical testing and measurements to create the necessary data has proved expensive and the case is now out of funds with only the 209 class submarines certified to mate with US rescue equipment. ODC has arranged a VTC between NAVSEA and Indian Navy SMEs to determine the way forward. In 2004 the Indian Navy signed a LOA with US for Deep Submergence Rescue Vehicle services worth $700,000. As per another cable Deep Sea Rescue Vehicle (DSRV) case was initially opened in 1997 but was suspended in 1998 due to sanctions. The case was restarted after September 2001.
