Wow...I'm in awe at you guys amd your knowledge
(and slightly jealous!).
Though as Bubblehead Nuke said, if there is a danger there could be pollution if the sub is torn apart in an explosion...do they design torps so it doesn't destroy the sub but just damages it enough to make it sink?
...also related...has anyone ever seen a photo of a nuclear torpedo exploding underwater? Would love to see one...or it's effects on the surface.
