Hi Willie!
I knew someone like you would be familiar with the location!!! It's the U.S.S. Michigan (SSBN727) somewhere off the coast of Alaska.
The first picture is also of the U.S.S. Michigan at USN Submarine Base, Bangor, Washington... As one can see, some of the crew are raising the colors!!!
The second picture is of the U.S.S. Michigan being degaussed at night... However, I cannot tell whether or not it's being performed at Bangor or Kings Bay?
The third picture is of the U.S.S. Pittsburgh (SSN696), a Los Angeles class attack boat, showing some of the crew on top of the "conning tower" or sail even though it does'nt operate as such when it's above the surface... Amongst them is no other than the former quarterback of the Pittsburgh Steelers who has an amazing four Super Bowl Championship rings, Terry Bradshaw!!! He's furthest to the right, wearing the submarine's baseball style cap, and sunglasses underneath, and to the right of the sailors who are both scanning the horizon with their binoculars.
The fourth picture is of the U.S.S. Pittsburgh's conning tower or sail again but this time, they're arriving back at Norfolk, VA after a successful tour of duty during operation "Iraqi Freedom".
As I'm writing this response to you, on the television set "Henry is talking to George Styckle, explaining to him that he's turned into a fish in the the Movie: "The Incredible Mr. Limpet!" I just thought I'd mention it ;)
Respectfully,
Henry
