I know you can't keep phyiscs a secret. So you are right in that aspect. All im saying is that as far as we know(which we don't) it has a fixed air inlet.
I remebering seeing a show about the F22 and they speculated that the 2 small squares on the nose were being used as addtional variable air inlets. Grated it's just sepculation.
But mach 2.5 just seems to slow to me for a Air Domaniance jet fighter.
The F-22 does not have variable intakes. The leading edges are fixed, and you can't have them internally without the plane literally exploding. This is a fact. Look at the inlets yourself and find a hinge point for them.
You're also confusing the F-22's (or F/A-22, if you buy the current mission tasking) mission. It is not a high-speed interceptor. It's an air superiority fighter and now they're claiming a multi-role fighter. Supercruise, which it has, is more desirable than max speed. It is also, because of the stealth characteristics, a very slow aerodynamically.It is well known that the F-22's engines are capable of easily overspeeding the airframe. The engines aren't the limiting factor in the top speed equation, the airframe is.
Now, the bleed doors on the spine look suspicious, but an understanding of how they work eliminates them from being able to allow the 22 to break the 2.5ish barrier.
Finishing blow: I've been inside the Marrietta, GA plant where F-22s are assembled. Because I don't have the need to know and wasn't made to sign anything, I can tell you that I saw the intakes under construction and there certainly was no variable intake mechanics. If such a thing was passed Classified in nature, I would not have been able to even see it from a distance, much less touch it (which I was still looked at sternly for, but common, F-22!). They also make the C-130J models there. Stupid C-130Js.
