I think that its quite a stretch to assume that Allies could have and therefore would have developed effective counter measures in a matter of months. It still took them years to tackle the problem of the Type XXI even after they had examined and tested actual Type XXI's directly.LeopardTooth wrote: If Type XXIs had appeared in large numbers in, say, 1943, and convoys across the Atlantic started taking unacceptable losses, developing such technologies would have been the highest, emergency-level national priority for Allied scientists, and would presumably have been introduced before too long..
5 The Type XXI had retractable Hohtenweil PPI radar (FuMO 63u). However a water proof version of the Berlin 9cm radar which could be used underwater was to be used.
.This radar which saw some use on Torpedo Boats (very small German destroyers), e-boats as well as Prinz Eugen used dielectric rod radiator arrays in a disk shaped antenna perfectly suited for encapsulation in a streamlined lenticular antenna for extension while the submarine was underwater
the non 'abandonment' of the German microwave program in late 1942
The Kriegsmarine did opperate its "Monsun Gruppe" in Malaysia. (Penang or Georgetown).RF wrote:I might add to the discussion that if the Type XXI was operational in 1943 then its impact would not be confined to the Atlantic or Arctic convoy battles, though those would be the critical battle areas.
It is likely that a number of these subs would be sent further afield, into the Indian Ocean and the Pacific. Imagine the impact of a few Type XXI's if they got among the US carrier forces at Leyte Gulf?

The Germans were working in Wh materials into the pressure hull in place of regular ST-52 construction steel. Wh has ~ twice the strength.alecsandros wrote:Theoretical crush depth 290meters...RF wrote: Am I right in thinking that they could also run deeper than the normal U-boats?
In reality, it could probably go deeper...
The KM's use of this wave length may have been so that it would not interfere with listening for Allied 9cm and 3cm emissions using radar detectors such as Tunis, Naxoz ZM, and Athos. Another possible factor is that 6cm magnetrons produced more power (15kw) than the 9cm magnetrons (10kw).Siegfried wrote:The 5.8cm Frequency seems odd, neither 3cm or 9cm but almost exactly in between. ...
Apart from Lorenz, which used anode modulation there was a sluggish move to anode modulation at GEMA and Telefunken which left the German radars precise but as little weak even though they found other ways of extending range and evading Jamming.
HMMM...''had Germany been afforded time'' - there is another aspect to this. Namely Hitler and the way Germany was run from 1933 onwards. Nazi rule was based on divide and rule, physical strength rather than brain power.... not really conducive to scientific and technological development, or to raising labour productivity, or to achieving an optimum allocation of resources....Byron Angel wrote:A stupendous amount of cutting edge technology was clearly involved with the Type XXI. Had Germany been afforded time to get all the systems working as advertised, the XXI would have been a great threat to seaborne comerce......
