Thanks to both replies. I was thinking of the F15, so I thought it
might be the center of gravity. I'm going to see if I can find photos
of the other models mentioned.

Yes, a fighter speed brake is completely different from most of the replies
you got. A fighter has the speed brake on the fue forward of the tail and
it is only similar in name to a "spoiler deployed as a speedbrake".
