Re: Type XXI and the Atlantic battle?

I'd say having reliable acoustic homing torpedoes from the start would have been a far larger advantage than the Type XXI.  That way escorts could be taken out easily enough; firing an acoustic down a...

They didn't have acoustic homers from the beginning though, plus they could always have worked on them and given them more sensitive seekers as the war went on (plus a deeper firing depth).  Making...

Not sure that even that lower level of high tech is what was needed. Looking at the figures on the Subs forum on how many U-boats to win the answer seems to be Germany should not start a tonnage war...

Re: Type XXI and the Atlantic battle?

I suppose what it boils down to is this: for all the German's vaunted reputation for technological innovation, did they actually deploy anything (prior to the XXI) that was any more effective, or even...

Re: Type XXI and the Atlantic battle?

Much of the KM's weapons development for its submarines was driven by the Allies success in countering the U-boats. This means more U-boat success means less effort for things like homing torpedoes....

"in 35 of those 45 months, US subs were operating with defective torpedoes." You're saying the torpedo problem wasn't fixed until November '44? I don't think so.

Re: Type XXI and the Atlantic battle?

Germans counted on high submerged endurance and deep diving from the early war on, not late 1943. This allowed them to survive most counter attacks- after they had mounted attacks on Convoys. Germans...
