Flak Guns
 

I'm getting beat to @#$! on the surface at night. Yes I have the only radar detector available. I made it back with 25% hull and the conning tower completely destroyed last patrol. I've just replaced the 3.7 with a C/48 Flakvierling. If I remove the deck gun with Sub Commander can I replace it with additional flak gun on the front. The sub is a IXC with the third conning tower.

Sinking Fast er....Faster

You can replace the deckgun with a flak if you get the U-Flak Conning tower, that the only way I know of.

Depends what your your in your going to get pounded to hell by planes the c/38Flackvierling and the quad are available from late 43 I think the 37mm I trash that as soon as the quad becomes available. but be careful it dies expend a lot of ammo.
