A typo, Al. Relax. The line should have read YF-23. Second, the Type
XXI and XXIII U-boats that did employ the Alberich covering were
undetected, so were Type VIIs with the stealth schnorkel raised. The
radar absorbing paint became the basis for the type found on the
latter U-2s and yes, we did steal the entire radar defraction scheme
from a single Russian source.

Well now given that most Type XXI's never left the shipyard I suppose
its accurate to say they werent detected. U-Boats that dont make
operational patrols are rather hard to spot.

Despite the fact that the design was completed in June 1943
and the first boat launched in May 1944 only 2 type XXI's ever
went on war patrol IRC and the first such patrol was on 30th April 1945 !

The Germans never detected any DeHavilland Vampires on radar
either, does that make it a stealth aircraft do you think ?
