and the no aft tubes thing... turn on "Super SPEED", you can run circles around escorts just reorient yourself for a front shot. This thing is a beast!

On the other hand you have a big advantage... You have the advantage of a 6 shot spread on the front, great for that big warship... worry less about a dud or miss and you're likely to stop it in its tracks.

I am surprised nobody has mentioned the range of the Walter at slower speeds.
I just tested and got submerged range of
4500km @ 5knots!
2500km @ 8knots!!

The limiting factor becomes the CO2 build up with no snorkel.

I think the type XVIII is a fascinating prototype that never was and an important step in the development of the type XXI.
It's just preposterous to have them in the pacific in 44.
I would probably play a career if it was 45 in the north sea.

I'm so wrapped up in the American campaign, I haven't even taken the XVIII out for a spin yet.

This makes me very interested in doing so.
