The concept of kinetic-energy weapons has been around ever since the RAND Corporation proposed placing rods on the tips of ICBMs in the 1950s; the satellite twist was popularized by sci-fi writer Jerry Pournelle. Though the Pentagon won’t say how far along the research is, or even confirm that any efforts are underway, the concept persists. The “U.S. Air Force Transformation Flight Plan,” published by the Air Force in November 2003, references “hypervelocity rod bundles” in its outline of future space-based weapons, and in 2002, another report from RAND, “Space Weapons, Earth Wars,” dedicated entire sections to the technology’s usefulness.

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.)
