INS Kursura Museum

INS Kursura (S20) is a Soviet-built Kalvari-class submarine that served in the Indian Navy from December 1969 until decommissioning in February 2001 after 31 years of distinguished service. Now permanently berthed on RK Beach in Visakhapatnam, it is the first submarine museum in Asia and the second in the world. Visitors can walk through the interior and explore the cramped living quarters, torpedo rooms, and control systems used by its crew.
