What is the maximum speed of the F-22 Raptor

over 1,600 MPH!!!

top speed is around mach 2.5, i've also heard mach 3 which translates to 2000+ mph

The F-22 is top speed has not been released but some educated guesses can be made based on its inlet structure & what is known about its engines. One of the biggest problems with supersonic flight is with shockwaves interfering with engine operation. A turbojet or turbofan engine cannot use supersonic air. This is overcome in most supersonic arcraft with some form of variable inlet. One examole of this is the inlet on an F-15. If u look closely, u will notice that the inlet can angle downward. Just below supersonic speeds, such an inlet will adjust to force shockwaves away from the inlet & slow the icoming air down to subsonic speeds. The higher the mach, the more difficult this becomes. The F-22 does not have variable inlets, which means that engine management above mach 2 is bound to become impossible or at least much, much more difficult. Furthermore, the F-22 is engines r optimized for supercruise & greater acceleration, not top speed. This means that the F-22 is not likely to be quite as fast as the F-15 (the F-15 was designed to be as fast as possible without titanium & steel construction) & definitely not a mach 3 aircraft. This is more than made up for by its ability to supercruise. The F-22 will cover more ground in less time, with a lot less fuel than an F-15 could. Even if the F-22 is as fast as an F15, it is definitely not a mach 3 aircraft. There r major reasons for this. First is engine design. The SR-71 cruised at more than mach 3. At such speeds, the variable inlets converted the jet to ramjet operation to gain the neccessary efficiency to operate at such speeds. This required a massive, complex, & heavy sytem. The F-22 has a surprisingly simple inlet & engine configuration that simply cannot deal with those speeds. The second major problem with mach 3+ flight is structural. The SR-71 did its mach 3 cruising at 80,000 ft. Even in such frighteningly thin air, the skin recieved enough friction to heat it to several hundered degrees. This required an all titanium skin, among other design traits like expanding panel joints & special hydraulic fluid. The F-22 is made of aluminum, composites, & a comparatively small amount of titanium. The titanium is also internal structure, not skin. The F-22 is airframe simply could not withstand mach 3 flight without damage. It is possible that there r some undisclosed engineering tricks in the internal inlet channels and/or possibly some unknown design traits in the engines themselves allowing such high performance, but this is very unlikely. All available information indicates the F-22 should have a maximum speed of mach 2.2 or 2.3 at altitude & around mach 1.3 at sea level. The truth is, it does not need to go any faster. With supercruise, it will still outrun anything else out there.

The actual top speed is classified, but it is in excess of Mach 2.

As demonstrated by the YF22A,max;level speed ''clean'' at 36,000 ft; Mach 1.58 in supercruise mode and Mach 1.70 with afterburning at 30,000 ft;

Actual speed at altitude is still Secret, but a 2.0-2.2Mach is a good estimate. Keep in mind that absolute speed is no longer a prime factor in air combat. AGILITY is primary: acceleration, ability to load up both instantaneous & sustained G. Maximum speeds above 1.0 Mach use tremendous amounts of fuel, & limit maneuvering. The majority of kills since Korea have been against aircraft that r trying to separate due to fuel; also nearly every air-air engagement has been subsonic-transonic.
EDIT: Somewhere else someone mentioned that pilots go through their entire career without flying at max mach. This is very true. In my case even though the Rhino was ''2.0 Mach capable'' the fastest I've ever gone is 1.65Mach.
Finally the F22 is ''supercruise'' is still after a year problematic at best, & has issues datalinking with assets other than AWACS.

mach 2,1 l know l have one l garage.. ha . offcource there is a little diference depending you r fly at cloudy or sunny day>)
