The INS Kursura, a decommissioned Indian Navy submarine, has been beached on the RK Beach promenade and converted into one of the more unusual museums in India. Visitors walk through the full length of the vessel — torpedo tubes, control room, sleeping quarters, and engine room — with exhibits explaining the mechanics of submarine warfare and the vessel's operational history.
The interior is cramped in the way all submarines are — the tour makes viscerally clear how 80 sailors lived and worked in this space during active service. The museum is open daily except Monday; there is a small admission fee. It draws both genuine naval history enthusiasts and families looking for something different from the usual beach activities, and it handles both audiences reasonably well.
