I saw a discovery wings show on this and it was amazing to see that they pushed this bird so hard the paint ripped off on a regular basis.

If it was closer to November, I bet my offhand remark about the Valk could turn into a liberal vs. conservative argument.

Well, as a general rule, those planes make a lot of noise.  However, there are no anti-aircraft weapons that function acousticly.  Just because they know its there gives them very little offensive options.  The plane relies on stealthy (radar wise) speed to get in and get the job done and get out without a hitch.

The USSR did have accoustic sensors in the Ural Mountains as an 'Early Warning System'. Not exactly accoustic-directed AAA, but for the purpose of alerting conventional AAA

I think the F22 max unloaded speed is mach 2...not for sure.    My aunt works for Lockheed-Martin, maybe i can get her to send me some specs or info on it.

F-18 is only mach 1.8 and can only pass the sound barrier with afterburners

the f-22 was designed with the idea of supercruise, ie. being able to reach speed of sound with just military power (ie no afterburners) so it uses less fuel and can stay faster longer than f-16's, 15's, 18's etc. So a mach speed of 1.5-1.8 for long periods is better than short jumps with todays more conventional aircraft.

One primary reason for the published maximum mach of 1.8 is due to the engine inlet design.  To fly well into the mach 2 speed range, you need fairly complex and non-stealthy movable inlet ramps that help slow the airflow down to the subsonic speed required by the engine to keep running.  A lot of the air that goes through the inlet ends up being dumped overboard at the highest speeds.  The F-14, F-15, SR-71, XB-70 and even the Concorde use(d) such complex inlet designs.

This page http://www.concordesst.com/powerplant.html has a great section on supersonic inlets as they apply to the Concorde.
