Made a Sea Lance for myself, the MK50 torpedo skin is not too bad I think. The missile is.. meh... but well it works.
The problem with the game is ofc 1. the torp doesn't hit surface ships - devs made it like this in the patches. 2. AI subs don't attempt to evade the air dropped torp. 3. It takes at least 2 torps to sink a SSN so if it's used often on SSNs in campaigns it's more returning port for reloads.
But well it's still fun to drop it on a diesel SS, or once is a blue moon, that SSN trying to flee 30k yds out - yep it's happened to me..
