In fact, the US projected and near developed a hypersonic nuclear powered cruise missile-unmanned bomber back in the 50-60s under the "Project Pluto". It was called SLAM (Supersonic Low Altitude Missile), and it was powered by a nuclear ramjet . The range of the thing was supposed to be almost unlimited. And it probably had been as destructive simply flying around and leaving a trail of fallout as attacking the target with nuclear warheads. Sometimes i wonder how humanity managed to survive those crazy kerbalian years...Hehehe the Tsar Bomba is so amazing. It was supposed to be a 100 megaton explosion, but the designer felt so uneasy about the specter of radiation contamination that he dialed it back to 50 on his own.
Oh, I think it was the US that had a nuclear powered bomber. They never hooked up the reactor to a propulsion system, but they did fly an active reactor on a bomber in a few test flights. In the Space Cadet threads VR and I talked about it on one of the first pages.
Very Kerbal indeed.
