not "based", i should have stated that different im sorry sir, the 22 was the start of all of the new superiority 5th gen fighters... the design is somewhat incorporated into the 35, all anyone has to do is look to see that... but you are correct, they are not anywhere near the same besides the looks, the 22 is a twin engine, and the 35 is a single engine, that moves, the 22s are fixed like that of the f-14 and F-15, they both have stealth capability tho.. to me, its as if the F-22 is to replace the mighty Tomcats, and F-15s, and the Lighting is to replace the F-16, fully... cant wait to see what they come out with to replace the F-18s, the Superhornets are cool, but alot more can be had IMO...
