That report dosen't reflect the true picture of F22the main problem of F22 is:-
1)can't engage in DOG fights..
2)vunerable to RAIN
3)ist skin is hitech but can even with stand rifiles bullets..
4)will have criticall failure for every 1.7 hours of flying..
5)cant communicate with its friendly USAF fighter because it STEALTHY....
and very costly plane...but not cost-effective...
You are partially correct , but airframe is not coated as you speak .he airframe is coated with emission absorbing material ....during flying the airframe beame hot and due to air frection this coating gets damaged...to make a ture stealth aircraft , inplace of coating we would be needing a emission absorbing matrial to
Radar absorbent material (RAM) is needed mostly on intake lips and wing leading edges ."Radar absorbant materials, or RAM is applied sparingly on the F-22 airframe as opposed to the entire airframe on the F-117. This is because designers have incorporated curves on crucial surfaces and edges, which lessens the need for RAM"
