The "YF-22" has not been canceled, it is in
production, the German "stealth" project was a complete failure, the
RAM on the Nazi's U-Boats was completely in-effective.

Note that the German WWII sub coatings *did* work a bit. At least,
until they were exposed to sea water, which deposited a lot of
microscopic material on them which screwed up their stealth properties.
They also didn't "stick" very well.

They also had some stealth coatings for airframes. Which had the
unfortunate tendency to peel off in flight...
