INS Kursura Submarine Museum

INS Kursura Submarine Museum is a decommissioned naval submarine preserved as a museum on Ramakrishna Beach in Visakhapatnam, Andhra Pradesh. The Soviet-built Kalvari-class submarine INS Kursura (S20) served the Indian Navy from 1969 to 2001 before being converted into a museum in 2002. It is India's first submarine museum and displays original compartments, equipment and naval artifacts, offering insight into submarine life and naval history.

Visitors can explore the preserved interior of the 91.3-metre long submarine beached on RK Beach. Inside, narrow corridors lead through original compartments including the control room, sonar and radar rooms, crew living quarters, engine room and torpedo section with operational instruments, uniforms and models retained. Guided tours explain functions of each section. Outside, the submarine hull is displayed on the beachfront promenade with views of the Bay of Bengal.
