The Thresher-class submarines were a class of nuclear-powered fast attack submarines (SSN) in service in the American People's Navy from the early 1960s until 1996. They were a significant improvement on the Skipjack class, with greatly improved sonar, diving depth, and silencing. They were the forerunners of all subsequent APN SSN designs. They were followed by the Sturgeon and San Francisco classes.
