pukaman, I love F-14s as much as anyone... but the F-22 is much better, and all things considered, the F-14 cost too much, and it was becoming obsolete, it had its day. The F-22 is a much better fighter, and anyone in their right mind knows that. Stop trying to argue it!

As for the IRST, it doesn't even match your initial statement in range (100+ nm), I have even founnd an article stating it is only effective up to 25nm (the F-14's AN/AAS-42 at least).

As I said, stealth also means reduced heat signature. As for Jane's, that is not an official source, but even so I couldn't find any estimate of the radar's range there. AFAIK maximum range of the AN/APG-77 has not been officially disclosed. 120nm is extremely low though, even the F-16 which is older and not so much BVR oriented has a radar with a 160nm max range.

Jane's states that it's current range is 120-125 miles, with expected upgrades increasing it to 250 miles eventually. Concerning the IRST, that was only concerning my initial statement of the AP-71 eqalling the APG-77's range. And I do believe it has more to do with the heat signature given off by the plane as opposed to the size.

You should also know that stealth does not mean only reduced radar signature, it also means reduced visual and heat signatures. And you should also know that the F-22 also uses an IRST derived from the AN/AAS-42.

First of all I don't know where you got that the AN/APG-77 has a max range of around 100nm, I believe it is not published but it is reported to have a maximum detection range against a fighter sized target of over 180nm. And it's max range will be even higher.
I also don't know where you got that the IRST has the same range as the AN/APG-71, it is reported to be able to ID a 747 at 100nm, for a fighter sized target it will be significantly less (maybe even half of that).
PukaMan (November 30, 1999 at 12:00 am)
oop correction: The APG-71's range is about 220 miles, so it's almost twice that of the F-22's APG-77.
PukaMan (November 30, 1999 at 12:00 am)
Except that the F-14's APG-71 and the F-22's APG-77 have about the same range, and the Tomcat's IRST matches that.
kosmo177 (November 30, 1999 at 12:00 am)
Not while being outside the F-22's radar range though. And if you're in there you're dead before you know it. So again, no.
PukaMan (November 30, 1999 at 12:00 am)
Except that F-14s are also equipped with a very powerful IRST which would pick up an F-22 easily, and passively (i.e. the Raptor wouldn't know it was being targetted) |
