We feel curious of many things regarding fighter aircrafts. I had a question if we have any fighter plane which is deadly enough to not detected on radar. There has been some instances of F-22 not detecting on radar.
“I can’t see the [expletive] thing. It won’t let me put a weapons system on it, even when I can see it visually through the canopy. [Flying against the F-22] annoys the hell out of me.”
– Stephen Chappell, RAAF Squadron Leader, F-15 exchange pilot in the 65th Aggressor Squadron.
Raptors wield ‘unfair’ advantage at Red Flag-
May not be exactly related to your question but some real-world instances of F-22 getting extremely close without being detected. The first is of F-22 interrupting an Iranian F-4 on mission to intercept an USAF drone. (2013)
He [the Raptor pilot] flew under their aircraft [the F-4s] to check out their weapons load without them knowing that he was there, and then pulled up on their left wing and then called them and said ‘you really ought to go home’.
The whole time Iranian pilot nor the ground controllers (who were guiding the F-4 on an intercept mission) had any idea about the F-22, till the Raptor pilot broke the radio silence.
The second one was in Syria, 2016.
The F-22 came within 2,000 feet of the aircraft without the Syrians aware they were being shadowed.
“All I needed at that point to shoot them down was a report from the ground that they were being attacked”
“We were in a perfect position to execute that with some pretty advanced weaponry.”
