Glomar Explorer

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