Project Excalibur was a United States government nuclear weapons research program to develop a nuclear pumped x-ray laser for ballistic missile defence. It became part of the Strategic Defense Initiative (SDI). Conceived by nuclear scientist Edward Teller, the concept involved packing large numbers of expendable x-ray lasers into a nuclear bomb. When it detonated, the bomb would fire laser beams in many directions. The intention was to shoot down enemy nuclear missiles. The plan was to place the whole apparatus on a satellite in orbit. It would have actually required many satellites in orbit, since there needed to be at least one between the U.S. and its enemies when a massive launch of intercontinental ballistic missiles (ICBMs) occurred. The Soviet Union was the only foe technologically able to accomplish a massive simultaneous launch.
