Brilliant Pebbles kinetic orbital strike system

Brilliant Pebbles kinetic orbital strike system is a ballistic missile defence system proposed by Lowell Wood and Edward Teller in 1987. It consists of thousands of small missiles, which are be placed in orbits so that hundreds would be above the Soviet Union at all times. If the Soviets launched its ICBM fleet, the pebbles would detect their rocket motors using infrared seekers and collide with them.
