The Tungsten "Bomb"

If the government spent as time trying to solve problems at home as the did in finding ways to kill our enemies, we would be living in a utopia by now.

Project Thor was a work around to avoid the apparently all too constraining nuclear treaties that we had signed.  In effect projectiles would be put into earth orbit and released with a small amount of thrust to the intended target.  Essentially it is a solid tungsten telephone pole and not an explosive.

The most described system is "an orbiting tungsten telephone pole with small fins and a computer in the back for guidance". The weapon can be down-scaled, an orbiting "crowbar" rather than a pole.  The system described in the 2003 United States Air Force (USAF) 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, and strike 25-foot accuracy.^[3][4][5]

by John Macneill Space-based weapons have exceptionally disparate advantages and disadvantages: They are extremely powerful and difficult to defend against, but they’re also expensive to launch and maintain and they’re in constant motion above the Earth. John Macneill
This technology is very far out—in miles and years. A pair of satellites orbiting several hundred miles above the Earth would serve as a weapons system. One functions as the targeting and communications platform while the other carries numerous tungsten rods—up to 20 feet in length and a foot in diameter—that it can drop on targets with less than 15 minutes’ notice. When instructed from the ground, the targeting satellite commands its partner to drop one of its darts. The guided rods enter the atmosphere, protected by a thermal coating, traveling at 36,000 feet per second—comparable to the speed of a meteor. The result: complete devastation of the target, even if it’s buried deep underground. (The two-platform configuration permits the weapon to be “reloaded” by just launching a new set of rods, rather than replacing the entire system.)

This is an awesome amount of power with surgical accuracy.   Something like this floating around up there is down right scary when you figure the frequency that satellites fall out of orbit and hurtle towards earth.
