INS Sindhukirti (S61) (Glory of the Sea)[4] is the seventh Sindhughosh-class diesel-electric submarine of the Indian Navy. She was built at the Admiralty Shipyard and Sevmash in the Soviet Union.

Sindukirti was commissioned on 9 December 1989 in the Soviet Union, with Cdr. Ramdas signing her commissioning orders. She underwent a protracted "medium refit" from June 2006 until May 2015 at the Hindustan Shipyard at Visakhapatnam. The midlife upgrade was projected to be completed in 3 years but numerous delays postponed the submarine's return.[5] Having spent one third of her life in refit, she finally returned to service on 23 May 2015.[6]
