A submarine emergency communication transmitter (SECT) buoy Mark 9 Mod O is loaded aboard a simulated submarine hull section during testing at the Naval Ordnance Laboratory. When put into fleet use the SECT, which will ride outside the submarine's pressure hull and inside the submarine's outer hull, will be released and act as a surface marker if and when the ship is sunk
