The first an enemy aircraft should know that an F-22 is there is when a missile comes up their tailpipe.
Lousy tactics to let the an enemy eyeball our aircraft. Should intercept with F-15s supported by F-22s in case sh!t hits the fan.
Last week there was an F-22 at the Air Races in Reno. One could be within 40 feet of it and take all the images you wanted. I am sure that the Russians have all the info they want on it and have for sometime. The still got intercepted by an F-22 that flew under them and counted the rivets on the belly. That is nerve racking for an aircrew.
