I read an article some time ago about how the US Air Force was more interested in fighters that looked like what they felt fighters should look like, rather than simply effective fighters; designed for missions that they wanted to be important, rather than missions that are actually used in reality; and of course big orders with manufacturers, because that's where the top of the air force retires.
That article also pointed out that for those reasons, the air force hates the A-10, despite the fact that it's actually the most effective planes for one of the most common mission types that they have. But it's not what they want to do, and it doesn't look like an F-15, so it's no good.
