Glomar Explorer

Built at Sun Shipbuilding and Dry Dock Company in Chester in the early 1970s as part of the covert CIA Jennifer Project, this ship played a key role in U.S. Cold War espionage. Its mission was to obtain intelligence by recovering a sunken Soviet submarine three miles deep in the Pacific Ocean. In the summer of 1974, the ship's huge claw raised portions of the submarine, and six Soviet submariners were recovered and given a burial at sea.
