F22's big time. I was watching something on history that said 1 took out 6 in war games.
Mmm, mayhaps you should read about the results of Northern Edge '06...
Much misinformation in this thread, as has been stated. However, let us make a few things perfectly clear. (Note: This is my field. I WORK on this stuff...)
Radar: JSF and Raptor have the same radar. The exact same one.
Passive dectection: Raptor fully integrated sensor suite. JSF natch.
Maneuever: Raptor has high alpha capabilities (Vector T). Natch for JSF. This point is fairly useless and my personal opinion is that the vector thrust for Raptor is great for airshows, but in a fight mostly ballast.
Armament (internal): JSF 2x AIM-9, 2x multistore; Raptor 2x AIM-9, 6x AIM-120 (or download 4 AIM-120's to get 2x multistore)
RCS (published): Both are less than 0.01 M^2, officially.
To sum, different platforms, different missions. To elaborate:
A2A (Typical): 4-ship Raptors (two-two, mutual support). 6x4= 24 AIM-120's at range. Detection can be passive or active. Targeting is active, but can be delayed until terminal approach. (i.e. Raptor picks up emission from Bogey, sensor suite analyzes total emissions from bogey to characterize as Bandit. Launches on vector from passives, goes active for final corrections until missile terminates. Bandit gets their first threat warning typically <1 sec prior to impact.) Basically, 24 shots at range (+75 miles, pending detection).
For JSF, no integrated passive suite, but same radar, so same active detection range. 4-ship of JSF has max 2x4=8 total AIM-120 shots.
JSF versus Raptor (assume same RCS, heh). JSF must be ACTIVE to detect Raptor. Raptor may launch early, due to passive aquisition of JSF's lit nose. (If you are using a flashlight to find someone in the dark, how far away can THEY see YOUR flashlight, eh?) At launch, 24 shots versus 8 shots, with the Raptor launching early. You do the math...
All that said, JSF has a much better A2G loadout. Makes sense, as that is what it's designed for, a bomb truck that can defend itself.
As for other platforms:
Raphael: No AESA radar. Much higher RCS. Good luck with that..
Typhoon has a decent AESA, but still a pretty high RCS. A better chance than Raphael, but not by much.
Visual range (dogfighting) doesn't mean much. If you're in a Raptor and you've got a target within AIM-9 range, something is wrong with your leadership's ROE. If you are overmatched, push to MIL and extend/disengage. If you MUST engage at a disadvantage, you've got the best E sub S ratio on the planet. Use it. And hope your wingman is doing his job in the Loose Duece.
Raptors die due to stupidity (this includes politics), not technology.
