The 15 can prob sustain a higher speed longer than the Rapter, i could be wrong, dont know, so much truth is behind classified BS, that the media will never know.

The F-15 would have to use afterburners to get anywhere near the speeds of the Raptor, and then it could only do so briefly before reaching Bingo Fuel.

Guys,

A friendly reminder to keep the discussion on topic. The other stuff, and you know what I'm talking about, is off topic. If you really feel the need to talk about those other stuff with some other members, you can always use the PM feature and discuss all you want.

I will not edit or delete what has already been posted for now. However, if it continues, they will be.

All you have to do it coast up to 45000 feet with some bags of gas hit AB and then get as fast as possible with the tanks then drop them and the F-15 should be able to maintain top speed for 15 minutes or maybe more. Why have they not put the 229s in the C model anyway sure that would help a lot?

When i look at the two aircraft, it just appears to me the 15 is built to go fast, while the 22 is more of a sleek sexy turn all over the place cruiser, while the 15 would have "suck my wake" written on the tail pipes lol.

The F-22 and F-35 will be able to sustain higher speeds for much longer periods than the F-15. Which, is vastly more useful than a few minutes at High Mach under ideal conditions. (i.e. > Mach 2)

In short under typical combat conditions. Both LM Types are faster as it relates to ACM's.

All the Eagle would have to do is coast up with two tanks then hit A/B and, then drop the tanks once they are used up, then get up to top speed. It should be able to do it for about 20 minutes that is decent for a 4th generation plane.

But after that 20 minutes you better hope there is a runway directly underneath you 'cause you're not flying 20 minutes (at MACH 2) back from where you came!

Yeah I bet or an airtanker stationed around the area, but with some modified engines it could maintain it and still have some fuel. I know that is not practical for combat but it would still be nice.

(oops wrong thread!) Doh

With full fuel and weapons, the F-22 will beat the F-15's acceleration, cruise speed, and top speed every single time.

I agree, that is why I am saying that I cannot see how the F-15 and F-22 can operate together in the new "hi-lo" mix proposed by the USAF. The F-15 would slow the package down, but I am sure the USAF has found a way to make it work.

What answer are you looking for?
If you are interested in learning - It's OK.
Back around 40 years ago, the F-15 was the F-22 of its day.
I just want you to think about that for just a minute.

Okay, just to clear up some things. First of all, asking whether the F-15 is faster than the F-22 is like asking whether the F-15 is faster than the Concorde. Higher top speed? F-15, obviously. Higher sustained speed? Easily the Concorde. The Concorde LIVED at Mach 2 cruising speed, and each one accumulated thousands of hours at that velocity. An F-15 with 6,000 hours on it may have hit Mach 2 or higher for at most a few minutes, likely in single digits, of its entire airframe life. In just ONE mission, an F-22 probably hits close to Mach 2 for longer than an F-15 will in its entire airframe life. It's just not even close, and silly to discuss it.

Secondly, the F-22 is not Mach limited principally due to its canopy. First of all, no VG inlets, one of the principal limiting factors. Even more so, however, is that its RAM coatings are not designed to survive much past Mach 2. Sure, it may be able to fly beyond Mach 2, but not for long, unless you want to hand back a peeled-off F-22 to one very pissed-off crew chief.

Any further discussion on this topic is silly and unnecessary.

Sure an old plane would not go that fast for that long but a mid or short life F-15 would be able to do it for 15 to 20 minutes. The Raptor was designed for stealth not top speed so it makes sense that it is slower. Sure it it can get to its top speed faster but it is not faster.

Agreed this is a silly discussion. Consider most combat take place well below M1.0 and I would think that speed above M 1.5 are pretty much irrelevant.

Which one is faster - The F-22 or F-15?
