Certainly some have gone bang - I don't think that's disputed. Well, there are a few who believe that a Trafalgar or Los Angeles SSN could collide with and sink a much larger Oscar II SSGN and then quietly sail away unharmed, I guess. The question is, has everything gone bang? The need to remove the front section before raising the Kursk means that those in charge think that it is a risk.
The Oscar II's can also carry a bunch of anti-ship cruise missiles. SS-N-19 "Shipwreck"'s IIRC. Not sure what they are going to do about those. Nasty things - scare the hell out of the navy.
Kermit - take a look at
www.bellona.no for some good environmental stuff, if you are interested. Pretty balanced for an environmental group too.
