1. The F-22 aerodynamic planform is tailored for Mach 2.2 -> 2.4 or whereabouts flight.
It will not
do Mach 3 or anything like it, such thinking is simply ludicrous.
2. Faster, Further, Higher was the old motto for combat aircraft (the last of which would have been the F-4 generation). After Vietnam, much more
emphasis was put on manouvering, initially subsonics, but now transonic and supersonic manouvering are high on the list of priorities.
3. The problem with going much faster than Mach 3/4 is mainly propulsion techniques and propulsive efficiency at speeds. A turbojet runs out of puff
at around Mach 3 or so [see
]. A RAMJET is good to
around Mach 4/5, after which a SCRAMjet is best [even it runs out of puff at around Mach 21 or so IIRC].
While the A-12/SR-71 used RAMjets, it was limited to around Mach 3.3 by heating and aerodynamic planform. NASA investigated making the things a bit
faster, but the return didn't justify the expense, so they decided against it. SCRAMjets are much newer on the scene, and the test of the X-43 was
the first public
flight of the propulsion system [perhaps the military have used it before, but I seriously doubt it due to the duplication of
What is really needed for the things I think you seek is a fundamental change in propulsion techniques, no longer sucking in/shooting out air or
whatever, but something that uses space-time distortions to move along. Unfortunately, we are quite a way off that, although I think some theories of
electro-magnetics allow for interaction with gravity, and indeed, ESA demonstrated this:
Kirkland, WA (PRWEB) March 29, 2006 -- The European Space Agency announced on March 21st the results of an experimental test in which a
superconductor rotating at 6,500 rpm is shown to gain acceleration as the result of what is believed to be a gravity-modification effect. As reported
by the ESA, "The experiment demonstrated that a superconductive gyroscope is capable of generating a powerful gravitomagnetic field, and is therefore
the gravitational counterpart of the magnetic coil. Although just 100 millionths of the acceleration due to the Earth’s gravitational field, the
measured field is a surprising one hundred million trillion times larger than Einstein’s General Relativity predicts."
