Fail.
You can’t have a supersonic stealth aircraft because due to the friction caused by the air rubbing against the skin of the plane the aircraft will heat up and light up on infrared tracking devices quite easily.
A supersonic stealth aircraft would be take. Out in short order.
I was at an air show that had a B-2 flyby. Besides looking like something out of science fiction what was most impressive was how quietly it flew. At a couple thousand feet directly over the crowd it made about as much sound as a bus passing by. Eerie quiet. Supersonic, or rather mach 5+ hypersonic, is what the next generation cruise missiles and bombers they’re simply not going to tell us about yet will be about.
