This is what the F-22 Raptor stealth jet looks like through the thermal camera

Screenshot from the thermal camera used by the EC-135 of the NPAS, based at Filton Aerodrome, west of Swindon, and shows one of the U.S. Air Force F-22 Raptor jets that deployed to RAF Fairford to take part in the Royal International Air Tattoo airshow, on the ground, at RAF Fairford, UK, in 2016.

It’s a screenshot from the thermal camera used by the EC-135 of the NPAS, based at Filton Aerodrome, west of Swindon, and shows one of the U.S. Air Force F-22 Raptor jets that deployed to RAF Fairford to take part in the Royal International Air Tattoo airshow, on the ground, at RAF Fairford, UK.

The photo is somehow funny, as it depicts the stealth 5th generation jet more or less as it would look like in a combat flight simulator, and interesting, because the IR camera caught the parked Raptor’s heat signature more or less in the same way an infra-red search and track (IRST) systems would perform passive detection of a radar evading plane.

In fact, F-22s and other stealth planes have literally no (or extremely little) radar cross-section (RCS) but they do have an IR signature. This means that they can be vulnerable to small, fast non-stealthy planes that feature low observable coatings and using their IRST sensors, hi-speed computers and interferometry, to geo-locate enemy LO (low observability) aircraft.

BTW, no radar test has ever been done to F-22. Some people rumor it has RCS smaller than a bee. But I think not possible, because US don't even have the technology to fight bad weather let alone achieve something like this. You need cloaking device to achieve this.
