The Vought SLAM was a proposed Nuclear Ramjet Powered Supersonic Cruise Missile in the 1950s. It would have to be launched using Solid Rocket Boosters, then it would power itself using the Ramjet powered by a Nuclear reactor after reaching a certain velocity. Initially it would cruise at high altitudes, then after getting close to enemy territory it would fly at lower altitudes to avoid the risk of detection and interception. Being nuclear powered, it had an almost indefinite range and could fly for days or weeks. Its maximum speed of mach 3 and ability to maneuver made it difficult to intercept. It carried 14 nuclear weapons onboard which would be individually deployed at seperate targets. After ejecting all weapons, it would loiter around enemy territory spewing all the radioactive air and dust around, making whatever soil it flew over virtually uninhabitable. After all that it would crash itself onto a target.
