The Thresher/Permit-class was a class of nuclear-powered fast attack submarines (hull classification symbol SSN) in service with the United States Navy from the 1960s until 1994. They replaced the Skipjack class. They were used primarily in the 1960s and 1970s, until replaced by the Sturgeon and Los Angeles classes.
The Thresher/Permit class resulted from a study commissioned in 1956 by the Chief of Naval Operations (CNO), Admiral Arleigh Burke. In "Project Nobska," the Committee on Undersea Warfare of the United States National Academy of Sciences considered the lessons learned from various prototypes and experimental platforms.

I picked up this model just a few days ago with the hull fully completed and weathered. It is done in 1/96th scale, making the boat approximately 35" long.

Got this unpacked last night and I'm very impressed with the finish. There are some minor blemishes in the paint weathering, but overall its a wonderfully detailed model.
Like my Thor LA, this Thor Permit boat needs to have its linkages reworked, but that should not pose a huge issue. For now, it will go into storage until I can find the time to work on it (or someone really, really wants to buy it!).

This boat was sold along with the LA class to the same person. Sorry for the lack of pics, but it was a whirlwind deal and I just didn't have the opportunity...
