I always thought it would be 60nm with the supercruise or am I wrong?

Hm. That's an interesting idea.

I don't know - these things are more or less classified. Keep in mind that the weapon steers itself so you lose some range from the drag this creates too.

Edit: I take the classified thing back. You can with -reasonable- accuracy model a ballistic shot of this type by computer. It will likely be optimistic to some degree but no big deal.

nm? Nanometers?

Nautical miles.

gunnut

You're off by a few factors...

A nautical mile is what...1850 meters?

I have a quesiton: why do aviators use nautical miles?

Nautical miles translate directly to longitude- 1 nm is 1 minute of longitude at the equator. So it's a convenient unit of measure for sailors and aviators who navigate great circle routes.

agreed with highsea on that 1

here is some more info

How did you calculate thrust to weight ratio? Using the website you gave, I have the F-15C with 47,660 lbs thrust over a normal takeoff weight of 44,630 lbs. for a ratio of 1.07. The F-22 has 70,000 lbs. of thrust and a normal takeoff weight of 60,000 lbs., for a ratio of 1.17.

gunnut

That's pretty much it. As you can see the thrust to weight ratio can change with stores and fuel load. A clean F-15C with half fuel can hit a pretty high t-w ratio while a fully loaded F-15E at take off might be below 1.

LOL I forgot about antenna receiver size you needa large seeker for that and even then its inaccurate. So TVM is imposible for such a missile. Command link guidance is fine but with the few nm the active seeker can detect it at plus the inaccuracy of the longwave not to mention the Raptors supercruise speed.I probabaly wasn't thinkin............

HAve you seen videos on YouTube of the F-22? It is pretty damn maneuverable for being a stealth aircraft: Thanks TVC!

Also, Paul Metz himself (test pilot for the F-22) said the F-22 is unstable by design, as well.

If memory is correct, instability has a lot to do with changing around the fly-by-wire system. (?)

The F-22 has almost the best of both worlds (stealth - maneuverability) so far, compared to ANY fighter ever designed.

Don't forget: The US has studied up on super maneuverability for many years. Remember HiMAT UAV back in 1979? Check out the X-29 in 1984; then we have the X-31, F-15 ACTIVE, X-36, F-16 MATV and AFTI, F-18 HARV. A lot of what we learned from those aircraft, went into the F-22 Raptor.

The PAK-FA is more of a challenger to the F-35 not the F-22. The thing the F-22 can do no other aircraft can do is to maneuver well above 60,000 ft at supersonic speeds! So just because the F-22 gets into a WVR fight, it doesn't mean the opposition stands much of a chance.

It is a form of reverse engineering. Intelligence can get you a lot of information but, to use descriptive geometry, exact measurements of distances and angles can be obtained on anything that can be seen by photos. All modern intelligence services use this.


In the red flag type exercise in Alaska (earlier this year) "Northern Edge" the F-22's killed an AWACS then the two F-15C escorts! The AWACS did not know it was shot down until the ground controllers told them. In that exercise the F-22 had a kill ratio of 108:0 and acted as an mini-AWACS and directed friendly fighters to a kill ratio of 32:1.
It also acted as a River Joint and detected mobile SAMs as they started operations. It then passed on the information by way of the data link so the attackers could destroy them. In test, the F-22 traveling at Mach 1.5 at 50,000 feet dropped a JDAM on a simulated S-300 target from 24 miles away! The F-22 has been cleared for operations at 65,000 ft.


The F-22 'exceeded' its spec and can cruise at Mach 1.5 for more than 600 miles. This is based upon the base for the F-22 is 410 miles from the forward edge of the battle area without tanker support.

In response to the statement that the F-15 is somehow superior to the F-22 is using flawed data. Its fuel fraction is higher, indicating the percentage of the overall weight that is fuel. Thrust to weight is greater, wing loading is less, etc. [SEE NOTE] The F-22 has the lowest drag co-efficient of any fighter ever produced. It weapons load/pylons cost no drag. Acceleration, climb and many other parameters are greater than the F-15 and F-16 anywhere in their envelope.
NOTE;
Most fighters have stablators the produce a down force or negative lift, to help control the pitch axis of a fighter. The F-22's stablator produces positive lift just like the wings and the area of the stablator is normally not counted in wing loading figures.

In test the F-22 had a knife fight with three F-16C's. They were equipt with high off boresight missiles with HMDS. The F-22 killed two of the F-16's and the third was killed but, the F-16 had already launched a missile into the F-22. So, all four aircraft died.
In other test one F-22 went against four F-16C's and killed them. Another test five F-15C's went against one F-22. All five F-15's died. None of theses opponents ever saw the F-22. In Northern Edge, F-14D's participate and dispite the IRST & TCS, it died like all the other aircraft.

And the F-22 can hit mach 1.7+ without afterburner now!

“Today I flew the Raptor at speeds exceeding (Mach 1.7) without afterburners,” General Jumper said. “To be able to go that fast without afterburners means that nobody can get you in their sights or get a lock-on. The aircraft’s impressive stealth capability, combined with its super cruise (capability), will give any adversary a very hard time.”

General Jumper qualifies in F/A-22 Raptor
