Look more like diesel boats. I saw a couple Delta IIIs way back in '84 when I was (ahem) 12 miles off the coast of Kamchatka right across from the inlet to Petropovlosk. Previous lifetime.
Seriously, you do _not_ want any of the old soviet nuc boats. Of course if someone wanted to give me one of the 637s rather than scrapping them I'd be first in line. Heck, I'd even take a 593 boat, though when I was on the 594 (Ballast Pt. sub base back in '80) there were baggies taped in the overhead to collect leaking hydraulic fluid.
For the record I was a Navy nuc for 6 years. I'd rather have been an aviator, but there was this thing about my vision
