Instead of an accidental torpedo strike, the new group suggested a mechanical failure caused an irreparable leak that flooded the submarine. In 1970 a Navy panel completed a classified report that disavowed the Court of Inquiry's conclusion. While some portions of the Scorpion's hull were never found, the wreckage that was examined did not exhibit the conditions expected from the hydrostatic implosion of a submarine hull structure. A six-month expedition in 1969 by Trieste II found no direct evidence to support the theory that the Scorpion was destroyed by a torpedo. Investigation of the boat's wreckage on the ocean floor found no evidence of torpedo damage. A six-month search eventually located the Scorpion's wreckage some 400 miles southwest of the Azores. Based on prior experience with such problems and an analysis of the accoustic signature of the Scorpion loss, the Navy initially concluded that the most probable cause of the loss of the Scorpion was the launch of an inadvertently activated torpedo, which turned and struck the submarine. SSN 589 SCORPION was lost on with 12 officers and 87 enlisted men - one of the worst casualties in the Navy's history. This reactor became the US Navy’s standard until the Los Angeles class joined the fleet in the mid-1970’s. Deep-diving and high speed capabilities were the result of HY-80 construction and a new reactor design, the S5W. Placement of the bow planes on the sail greatly reduced flow noise at the bow-mounted sonar. ![]() USS Skipjack was also unique in that it was the first nuclear submarine with a single shaft. The first submarine class to combine nuclear power with the new hull design was the USS Skipjack. In 1958 the the USS Albacore entered service with a "tear drop" hull design to reduce underwater resistance and allow greater submerged speed and maneuverability. ![]() Nuclear power enabled this submarine to become the first true "submersible" - able to operate underwater for an indefinite period of time. In 1954 the USS Nautilus, the world's first nuclear powered submarine, was launched. Skipjack Class was the first "top to bottom" new attack submarine design using nuclear propulsion.
