I think all this stealth stuff is overrated myself. RAF Tornados have reportedly intercepted (not aggressively, of course) USAF B2's flying across the Atlantic, having detected them miles away. And the F-117... personally I think it's a bit of a joke... not only is it really ugly, it isn't that stealthy (I read that the French-supplied radar systems used by the Iraqis in the Gulf detected them routinely, but the radar-guided missiles were foiled by chaff usually, as the jet does admittedly have a smaller RCS than a normal jet).
Perhaps the F-22 will be different though, with all the Emmisions Control (EMCON) systems reducing incoming and outgoing detectable transmissions and signals, and all the trimmings, like thrust-vectoring, internal missile bays, and a supersonic cruise speed without the use of afterburners... and it looks really sexy too.
Not that I'm sexually attracted to aircraft. Oh no.
