How about a nuclear fueled, ramjet powered supersonic low altitude missile (SLAM)?
Project Pluto was perhaps the most horrifying idea of the entire Cold War:
"
SLAM was perhaps the most fearsome weapon ever conceived. The missile was designed to deliver as many as 26 nuclear bombs over the Soviet Union in a single mission. It would do this while flying at Mach 3 and less than 1,000 feet above ground level. SLAM’s shock wave overpressure alone (162 dB) would devastate structures and people along its flight path. And, as if that were not enough, the type’s nuclear-fueled ramjet would continuously spew radiation-contaminated exhaust all over the countryside."
Let that sink in, this thing would be conventionally launched and then at a safe distance and altitude the nuclear reactor would kick in and fuel the craft for an almost unlimited amount of time. The plan was for them to circle over the oceans until being ordered "down onto the deck" to make their dashes in the Soviet Union.
So not only does it deliver 26 nuclear warheads, but its speed and low altitude destroys buildings with its pressure wave and it spews out deadly radioactive exhaust along its path.
Jesus. If that doesn't send chills down your spine you are one cold operator.
