submarine hatch
Underwater entry point
A submarine hatch is a watertight door or opening in the hull of a submarine, typically circular and sealed with heavy latches to withstand underwater pressure.
Hatches allow crew to enter and exit, access compartments, or load supplies and torpedoes.
The conning tower hatch is the main entry point when surfaced: The captain climbed through the submarine hatch onto the deck.
