And, if you had not noticed, the SU is about as stealthy as a 747.

If you had still not noticed, f22 and B2 are about as stealthy to multistatics
as a B52 to backscatterers.

Heck,in year 2004 we have still difficulty to explain some things that the
Germans and Brits knew in 40s to some people.

You can reduce backscaterers by hard body shaping very significantly,but
unfortunately you CANNOT do the same for the forward scatterers.That was the
lesson that Germans and Brits learned in 40s.
Thats also the reason why multistatic RCS of B2 is even greater than frontal
backscatterer RCS of B52.

Even Yale graduates should be able to understand that.
