I remember the conversation with goering and luftwaffe pilots during the battle of britain ...
Goering: What can I do for you?
Moelders: Upgraded engines for my Bf 109s.
Galland: A squadron of Spitfires....!!!

XXI sub help a lot with his 15 knts and fast torpedo loading. but only late in the war ( if you survive enough).
