USS Thresher (SSN-593)

Since 07-27-02

Thresher (SSN-593) represented a new generation of multipurpose nuclear submarine and was the prototype for all subsequent attack submarine classes.

She was the first quiet and deep-diving submarine and had a new, larger sonar array in the bow in place of the torpedo tubes (which were moved amidships).

Thresher was launched in 1960 and commissioned the following year. Tragically, she was lost on 10 April 1963 with 129 crewmembers and civilians during a deep test dive, due to accidental causes still uncertain today.

Lessons from the disaster were incorporated into follow-on nuclear submarines.

After the loss of the Thresher, the class was renamed for the USS Permit (SSN-594).
