Cobra manouvre ain't much.
I appreciate much more the plane that is stealthy, with far better onboard computer systems, than that that could execute cobra manouvre! And the Su was made to rival the F-15. In some things it exceeded F-15, but the F-15E is much better thatn it's predecessor, even there are some experiments that are made on F-15 about 3D vectoring systems, since the Raptor won't probably get more money from Congress, and the project will probably be abandoned. It's not a very bright decission on my opinion, but the plane is still classified so maybe the Congress knows probably more than I do. Anyway the new F-15 will certainly exceed most of the planes in therms of manouverability (maybe not Gripen and the F-16).
1) The cobra manoeuvre
is much. It’s an indication of how controllable an airplane is. The aerodynamics on those Sukhoi fighter planes are brilliant. Don’t say “it aint much” it makes you look like you don’t know what you’re talking about.
2) there's more then one type of su, Sukhoi is a manufacturer, not a type, so
it wasn't "made to rival the F-15"
3) stealth is nice, but if the enemy fighter pilot sees you with his own eyes, it's useless, a good handling, manoeuvrable plane is what you need at shorter range.4) I know of the vectoring systems tested on f-16, and that works great, but it's not in production, so it won't do anything in real life right now.
5) I didn't know that the f-22 project would be abandoned, how do you know that?
6) What the new f-15
probably will or will not exceed is not the point, although I doubt that it will be more manoeuvrable then a new type
Sukhoi. The fact that you say that it probably won't outperform the f-16 is a good indication for that.
My point is, the world isn't black & white, it's grey tones. The US isn't "the best" at everything. That's no shame, it's just that people not born in the US can be intelligent too, even if they work for a Russian aircraft manufacturer. ( Don't forget how the US became the first country to have the a-bomb) Stop pushing the US military products to be the best. Oh and Redneck warned you to provide sources. I'd like that, 'cause for now it looks like you get your facts mixed up a little.
sorry Sherman....
