"Just looking" is often a deceptive activity. For RCS, the devil is in
the details.

That's true BUT RAM ingredients aside all that shaping and stuff is
pretty much open and using those criteria the Eurofighter comes up
short in MANY ways. In Ben Rich's book "Shunk Works" he mentioned
that during the developement of Have Blue there was an incident where
ONE screw was protruding an eight of an inch and it made the
difference between not being detected to having the RCS blown to ****
and being easily detectable. One screw an eight of an inch. Just
speaking from looking at the two aircraft visually and comparing
surfaces, discontinuaties and edges, there is no comparison.
