Scorpion was lost on 22 May 1968, with 99 crewmen dying in the incident. It was one of four mysterious submarine disappearances in 1968, the others being the Israeli submarine INS Dakar, the French submarine Minerve and the Soviet submarine K-129.

The secondary Navy investigation – using extensive photographic, video, and eyewitness inspections of the wreckage in 1969 – suggested that Scorpion's hull was crushed by implosion forces as it sank below crush depth. The Structural Analysis Group, which included Naval Ship Systems Command's Submarine Structures director Peter Palermo, plainly saw that the torpedo room was intact, though it had been pinched by excessive sea pressure. The operations compartment collapsed at frame 33, this being the king frame of the hull, reaching its structural limit first. The conical/cylindrical transition piece at frame 67 followed instantly. The boat was broken in two by massive hydrostatic pressure at an estimated depth of 1,530 feet (470 m). The operations compartment was largely obliterated by sea pressure, and the engine room had telescoped 50 ft (15 m) forward into the hull due to collapse pressure, when the cone-to-cylinder transition junction failed between the auxiliary machine space and the engine room.
