Given that I think I may be right in saying that more IX boats where
built than fleet boats; the Americans could scuttle all of the VII's and still
have a bigger fleet after they swapped with the Germans if they didn't
fancy supply boats.
The IX boats did fine in the tropics with out air conditioning and ice
cream machines too.

Did the Germans ever figure out how good the Allies got at tracking
active radar? Would they have turned it off?

Would the American Torps been much of a problem in the Atlantic campeign?
