"Everything starts as somebody's daydream. And, when you're daydreaming, it is science fiction. It's when you start work out how you put it together, true science fiction becomes real science."
- Larry Niven

I think human beings have always known that you have a special ally when you are fighting people who are below you.
The general concept can be traced back to the 1960s. At the annual meeting of the American Astronautical Society, in January, 1962 Dandridge M. Cole warned that as early as 1970 the Soviets could develop the technology to divert a near earth asteroid to impact a target on earth.
Ivan's Hammer, as it was called, is the idea to use a natural asteroid or meteoroid as a weapon of mass destruction in a first-strike role.
| "Project Thor was recommended by a strategy analysis group back in the eighties," Curtis said. "Flying crowbars." He sketched rapidly. "You take a big iron bar. Give it a rudimentary sensor, and a steerable vane for guidance. Put bundles of them in orbit. To use it, call it down from orbit, aimed at the area you're working on. It has a simple brain, just smart enough to recognize what a tank looks like from overhead. When it sees a tank silhouette, it steers toward it." |

Pournelle described a weapons system like this in 1964; he published a more complete description in 1975. He describes it this way:

Robert Heinlein used this general idea in The Moon is a Harsh Mistress; see the article for mass driver catapult.
The basic weapon system consists of an orbiting element some 20 to 40 feet long. It requires a GPS receiver to locate itself; a means of taking it out of orbit; an atmospheric guidance system, such as a means of changing its center of gravity (moving weights, small fins, etc.), and a communication system to give it a target and activate the system. No warhead is wanted or needed. Thor will impact a target area at about 12,000 feet per second; that is sufficient kinetic energy to destroy most hard targets, with minimum collateral damage and of course no fall-out. Achievable accuracy has been estimated at ten to twenty feet CEP (circular error of probability).
