| | 1 | Title: | The USS Thresher, lead boat in the Thresher class | Add | | | Summary: | The USS Thresher underway. The Thresher, the lead submarine in her class, was designed and built by the Portsmouth Naval Shipyard. This was a change from earlier practice; lead boats for earlier nuclear-powered sub classes were constructed by Electric Boat. The Thresher was lost at sea on 10 April 1963 with 129 crew members and civilian specialists on board. The precise reason for the submarine's loss was never determined. A court of inquiry found the most likely cause was a seawater leak in the engine room that started a chain of events that led to a loss of propulsion power. | | | | Source: | http://www.steelnavy.com/BWNssn593.htm | | | | Reference: | Rockwell, Theodore.

| 2 | Title: | The USS Thresher underway | Add | | | Summary: | Aerial view of the USS Thresher underway. The Thresher was constructed at Portsmouth Naval Shipyard. Her construction was plagued by difficulties, in part due to the use of HY-80 hull welds (needed to enable deeper submerged operations) and Portsmouth's lack of experience and proficiency, relative to Electric Boat, in building nuclear subs. The Thresher was lost at sea on 10 April 1963. A Navy court of inquiry found that engine room flooding, perhaps caused by the failure of a silver-brazed joint, resulted in a loss of electrical power and (following a reactor scram), a loss of proplusion power. | | | | Source: | http://www.history.navy.mil/photos/sh-usn/usnsh-t/ssn593.htm | | | | Reference: | Duncan, Francis.

| 4 | Title: | USS Thresher, bow view | Add | | | Summary: | A bow view of the USS Thresher (showing the sail and diving planes), taken in July 1961. The Thresher was the lead boat in her class, designed to support operations at a depth greater than that possible with submarines of the Skipjack class. The Thresher was built at the Portsmouth Naval Yard and was powered by an S5W reactor plant. | | | | Source: | http://www.history.navy.mil/photos/sh-usn/usnsh-t/ssn593.htm | | | | Reference: | Duncan, Francis.

| 5 | Title: | Brass pipe recovered from wreckage of USS Thresher | Add | | | Summary: | Photograph of a brass pipe recovered from the wreckage of the USS Thresher in 1963. The pipe was recovered by the bathyscaph Trieste, and it has the information "593 Boat" etched on the pipe. The Thresher was lost on 10 April 1963, with the loss of 129 crewmen and civilian workers. A court of inquiry determined that the most probable cause of the Thresher's loss was a seawater leak that led to a loss of electrical and propulsion power. | | | | Source: | http://www.history.navy.mil/photos/sh-usn/usnsh-t/ssn593-k.htm | | | | Reference: | Polmar, Norman.
