SUBSIM Radio Room Forums - USS Stickleback found

On May 28, 1958, Stickleback was participating in an antisubmarine warfare exercise with the destroyer escort USS Silverstein (DE 534) and a torpedo retriever in the Hawaiian area.
In the course of these drills, the submarine had just completed a simulated torpedo run on Silverstein and was diving to a safe depth when she lost power and descended uncontrolled to close to 800′. Emergency buoyancy ballast was added, and the boat ascended rapidly only to breach approximately 200 yards (180 m) ahead of the destroyer escort. On the assent a flare could not be fired as crew had evacuated the aft torpedo room. The collision alarm sounded, and Silverstein backed full, put its rudder hard left but could not avoid a collision. The result of which was a hole to the submarine on its port side and loss of the submarine.
