Kalvari-class submarines were the first submarines inducted into the Indian Navy. They were variants of the early Soviet Foxtrot-class submarines. Four of the class served in the Indian Navy. Four additional variants of the later Foxtrot class were inducted as the Vela class.

INS Kursura has been preserved as a museum on Ramakrishna Mission Beach in Visakhapatnam.[2] The sail of the lead vessel, INS Kalvari is also on display at the Visakhapatnam city museum.
