Sinking 53,443 tons of Japanese shipping, considering the SSN it could be this Lapon's sail was memorialized at American Legion Post 639, in Springfield, Missouri. ? Regards, Che.
I was going to guess the submerged radar attack of SS-260 that actually sank a Japanese ship, but your clue leads me to guess instead the 40 days that SSN-661 trailed a Soviet Boomer in the Atlantic.
ship We really must 'putter' stop to this! Bet there're a lot of birdies on board.! (Not as many as there were, someone putter hole in one!)
I thought that it would be the Type XIV Milchkühe. You know at first I wanted to make this an ironicaly question (Bismarck ), but now, it seems you´re right.
