I wouldn't worry too much about mach number, actual speed should interest you guys more. Although mach number is important, it depends on air
density, humidity, altitude, temperature and other factors. So Mach 1.7 at 10,000 feet on a warm day is much faster then Mach 1.7 at 50,000 feet over
the arctic. The "sources" that state these Mach numbers never say the actual speed in MPH or KPH or the altitude these speeds were achieved. Since
most things about the raptor are classified, it would be ridiculous for anyone not personally working with the F-22 to state any speeds, mach numbers
or not as its true performance. Anyway, I got my 2.6 mach number my calculating it based on many assumptions, so it could very well be wrong (I used
mach number because it gives me a margin of error of plus minus 200MPH). Although I am confident that the f-22 might even go faster. Until the
government lifts the vale of secrecy, we (the public) will not know.
IF I knew these numbers I could calculate is top speed:
Weight, drag coefficient, thrust, lift, and exhaust temperatures as well as operating altitudes I could give you a pretty accurate top speed in full
afterburner. These numbers are classified so I dont know....
I can promise you guys one thing though, if it can do over Mach 1.7 under military power (23,000 pounds each engine), it can atleast do Mach
2.15 at the same altitude and air conditions at full afterburner (35,000 pounds each engine).
