There's a LOT of Submarines in Washington State, for those interested. Have a look at Bangor Naval Submarine Base and Bremerton Naval Base. You can also clearly see the nuclear weapons storage facility and one SSBN in drydock on the delta pier. There's about 15 subs at Bremerton, several of which are moored outboard of each other.
I was stationed on USS Chicago, SSN 721 in San Diego, and while I was there, there were subs everywhere! I couldn't find any in the imagery, however - very odd. I know most of them moved to Hawaii (PH) after I got out...
