Well if they make DCS-10 that is only a close air support plane way wouldn't they make a SR-71, is just a which like any other.
But more than a SR-71 they could make a Recon version of all the planes and then yo get to do a recon mission and a bombing or intercept to.
All they have to include is the camera, ENLINT, SIGINT etc... pod's, the aircraft recon missions is alway cool to do cause you have to penetrate the enemy defenses, and no the sat aren't always in site for recon, and some time they are blinded by clouds or the enemy.
