France has nothing to do with the Eurofighter-They are building their own aircraft,the Rafale,which is'nt doing great either.Anyway,by the time the F-35 comes online,the full multi-role version of the Eurofighter will be ready.The EF-2000 is a better air defense aircraft than the JSF.
Except you can buy about 3 for the cost of 1 Typhoon. The F-35 is a strike aircraft, it is not optimized for air defense although it should do it well, because of its stealth and small size, the Typhoon would have a hard time fighting it, especially the VSTOL version (you can use it like vectored thrust, like with the Harrier). The Typhoon is a good air defense aircraft against the Flanker, but too expensive. The F-35 is a much better strike aircraft, and far more versatile. Modernized, F-16s, F-15s or Grippens are a much better buy if you want non-stealth aircraft for air defense that can also do ground well. attack.
Brother please.
Well, the MiG-29 is a much better airplane than the F-16 - but that doesn't really matter when you have a radar cross-section of that looks like a giant flying mirror. The AIM-120C, launched from an F-16, has claimed two very proficient Serbian pilots and their MiG-29s.
Same thing with the EuroFighter. It might be a "better" air defense aircraft, but it was built as a gun fighter or boresight fighter. Its agility in the furball isn't really going to matter when it looks like a "shoot me" sign to a Sidewinder or Slammer. That's the big thing about stealth - not only is it hard for the enemy to find you in the first place, it's very hard for his self-guided munitions to track you.
