Not swept wing, but adjustable wing...My buddy told me of the terrain radar when I asked him why he sold a Corvette he had. He replied that after going supersonic while 200 feet above a desert floor, fast cars weren't much of a thrill. It was a kick ass aircraft in it's day...during it's time, faster than most.
