Star Wars research: test firing of a railgun (Electromagnetic Launcher) at Maxwell Laboratories Inc. ,San Diego,California,as part of the U. S. Government's research programme into space-based weapons capable of intercepting ballistic missiles electromagnetism to accelerate a projectile towards its target,as opposed to rifles or rockets which use chemical energy as a propellant. Here,a 0. 3 pound plastic projectile is fired at about 3 kilometers per second (7,000 miles per hour) to penetrate a 1-inch steel plate (top) | |
