Unsinkable ships was precisely the reason why I stopped using NSM 3.3 and returned to the damage model in TMaru 1.6.4. This problem only occurred with destroyers and subchasers. Sometimes I could easily put as much as 9 torpedoes into a single destroyer, and it would sail away without even a slight list. I'm talking about 9 certain, confirmed with external camera hits here, no prematures or duds. Talk about being scared ****less, when a perfect down the throat shot only shakes the enemy for a moment, after which he continues his attack run like nothing ever happened. Strangely enough I never had problems with merchants or larger warships, only destroyers and subchasers. Other than that, NSM sure has potential and seems to work as advertised
