Only two nuclear powered US submarines have been unintentionally sunk. The other is the USS Thresher (SSN-593).

She was a 3500ton Skipjack class fast attack submarine comissioned in July 1960 and built in Groton, CT by the General Dynamics Corporation, Electric Boat Division.

Assigned to the Atlantic Fleet, she made several European tours before settling into a schedule of war games to develop tactics for the Skipjack class submarines. Following an overhaul in 1967 she was again placed on Mediteranean deployment in 1968.

On return to Norfolk something catastrophic occurred 22MAY1968 and all hands were lost. What that "something" happens to be has not yet been conclusively determined. Current data generally favors the "hot-running" torpedo hypothesis, with the torpedo exploding either within the tube or being launched and turning on the nearest target in the vicinity- the Scorpion.

A secondary hypothesis, based on the lack of any identifiable debris from torpedo room equipment in the wreckage and the manner in which the sail separated from the hull, suggests that the initial casualty was a hydrogen explosion resulting from an improperly isolated vent valve on the battery compartment.

While the ship carried two tactical nuclear torpedoes and was nuclear powered, continued monitoring has not revealed any evidence of contamination at the site.
