Rods from God
Nothing else comes close.
Thor !!!!!!!
From Wikipedia:
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 deorbit 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 would be no need to deploy missiles, aircraft or other vehicles
Ya beat me to it.
“Rods from God
Nothing else comes close.”
Oh yeah, how about anti-matter weapons?
Absolutely!
A 3” rod, 3 feet long, dropped from space packs about 12 kilotons of energy. And you can store a LOT of those rods in a very small space! Something the size of a refrigerator could hold 100 units. That’s a megaton of highly directed energy that will strike individual buildings, sites, etc.
And zero fallout to deal with!
