Project Thor: Project Thor is an idea for a weapons system that launches kinetic projectiles from Earth’s orbit to damage targets on the ground. The system most often described is “an orbiting tungsten telephone pole with small fins and a computer in the back for guidance.” The system described in the 2003 United States Air Force report was that of 20-foot-long (6.1 m), 1-foot-diameter (0.30 m) tungsten rods that are satellite controlled, and have global strike capability, with impact speeds of Mach 10. The time between deorbiting and impact would only be a few minutes, and depending on the orbits and positions in the orbits, the system would have a world-wide range. There is no requirement to deploy missiles, aircraft or other vehicles. The system is not prohibited by either the Outer Space Treaty or the Anti-Ballistic Missile Treaty. Some systems are quoted as having the yield of a small tactical nuclear bomb.
