The dummy sailor is inside the INS Kursura, a real submarine of the Indian Navy which was converted into a submarine museum after being decommissioned in 2001. 

INS Kursura (S20) was a Kalvari-class diesel-electric submarine of the Indian Navy. She was India's fourth submarine at the time when she was commissioned on 18 December 1969, The vessel was decommissioned on 27 February 2001, after 31 years of service. She participated in the Indo-Pakistani War of 1971, where she played a key role in patrol missions, in the Arabian Sea. She later participated in naval exercises with other nations and made many goodwill visits to other countries.

After decommissioning, the ship was towed to RK Beach in Visakhapatnam and was established as a museum ship, which is the first submarine museum in South Asia. The idea of the boat's conversion to a museum is credited to Admiral V Pasricha. Kursura has the distinction of being one of the very few submarine museums to retain originality. Despite being a decommissioned submarine, she still receives the navy's "Dressing Ship" honour, which is usually awarded only to active ships. Six retired naval personnel serve as guides and another one as the curator at this unique museum, which has become a famous tourist attraction of the city.
