Consider that by 2020, the United States is projected to have nearly 2,500 manned combat aircraft of all kinds. Of those, nearly 1,100 will be the most advanced fifth generation F-35s and F-22s. ... And by 2025, the gap only widens. The U.S. will have approximately 1,700 of the most advanced fifth generation fighters ...

By 2020, only 187 of those 1,100 "most advanced" fighters will F-22s, while the other 913 will be F-35s, many of which will be Navy and Marine variants.

By 2025, out of those 1,700 "most advanced" fighters, only 187 (or less depending on training losses) will be F-22s, while the remaining 1,513 will be F-35s.

The F-35 is only front aspect stealth, and as a strike fighter, it cannot dogfight it's way out of a paper bag against a good 4th generation fighters such as the Su-30, let alone the PAK-FA.

The air environment is very electronic, networked, and skilled operator/support intensive. I don’t really think it matters, if the Russians had the Raptors, and we didn’t.
