the x-4 missile is in the game and has rudementary controls, not self guiding though.
you fly it with trim, but if you ever manage to hit anything moving with it them kudos to you

Try it against heavy bombers, it was made to bring these down, not to dogfight fighters. And you don't actually need to hit to bring a say B-29 down, it's enough to get it explode near it to knock off a wing.
