USS Thresher (SSN-593) was the lead nuclear-submarine attack submarine of her class and was commissioned on August 3, 1961, at Portsmouth Naval Shipyard, Kittery, Maine.   Following commissioning, she completed trials in the Atlantic and Caribbean areas testing her new technological systems and weapons.   On April 10, 1963, following overhaul, Thresher began deep-diving tests, along with USS Skylark (ASR-20), about 220 miles east of Cape Cod, Massachusetts.  As the tests proceeded, Skylark received garbled communications from her which eventually stopped.   It became apparent she had sunk taking the lives of the 129 officers, crewmen, and civilian technicians.    Thresher's remains were located about 8,400 feet below the surface on the sea floor by the bathyscaphe Trieste, aided by USS Mizar (AK-272) and other ships.   After a review of evidence, the Court of Inquiry determined she had probably sunk due to a piping failure, subsequent loss of power and the inability to blow ballast tanks rapidly enough to avoid sinking. A model and photographic display onThresher can be seen in the Undersea Exploration exhibit area in Bldg. 76 of our museum.

A memorial to the 129 men who lost their lives aboard submarine USS Thresher (SSN-593) in 1963 will be dedicated this fall at Arlington National Cemetery, after a six-year campaign to win the Army’s approval for the project.

One of the Chiefs on the Nimitz from "M" Division got transferred off the Thresher about a week or two before that happened. He wore one of the Thresher belt buckles at times.

The review indicated that the designers specified electrical enclosures to only be resistant to water spray from above and the sides.  A leak (spray) from a sea water pipe leak from below would short out the electrical systems in an enclosure.
