Picture of B-2 "non existent" IR emissions: http://media.defenseindustrydaily.com/i ... _IR_lg.gif

Even the website posting that pic describes it as, "Speaking of which, see the graphic below of a B-2 Spirit stealth bomber at relatively close range, lifted from EADS Eurofighter’s presentation to the Norwegian government as they touted their own aircraft’s advanced IRST cueing sensor with 70 km range." What's a "relatively close range"? According to http://www.pprune.org/archive/index.php/t-276700.html it's a B-2 flying a known course straight down the Farnborough runway, at a range of half a mile and 500 ft. altitude from the IRST. And the tracking was actually optical, not by the IRST itself. For all that, this the kind of difference you see between the airplane and the background in the IRST image of a normal aircraft:

Absolutely zero IR signature? Of course not. But so little that you'll see it with your eyes before your IRST will be able to distinguish it from empty sky? Looks like that's a real possibility.

unrelated, but while the discussion is about IR signatures, this is pretty neat....

Yeah, but that's only when it takes off. If an enemy aircraft gets close enough to see that, it should be a smoking wreck on the ground. Thumb
