USS THRESHER (SSN 593)

LOST WITH aLL HANDS aND 17 CIVILIANS - 10 APR 1963

Lost on 10 APR 1963 with the loss of 112 officers and crew and 17 civilian technicians during sea trials deep-diving exercises following a prolonged shipyard period for refitting.

Fifteen minutes after reaching test depth, USS THRESHER communicated with USS SKYLARK (ASR 20) that she was having problems and attempting to surface. USS SKYLARK heard noises like air rushing into an ballast tank - then, silence.

Rescue ship USS RECOVERY (ASR 43) subsequently recovered bits of debris, including gloves and bits of internal insulation. Photographs taken by the bathyscape TRIESTE proved that the submarine had broken up, taking all hands on board to their deaths in 1,400 fathoms of water, some 220 miles east of Boston.
