IMEWS (Integrated Missile Early Warning Satellite)

IMEWS (Integrated Missile Early Warning Satellite) is a program of American military satellites designed to operate from geosynchronous orbit and detect launches of enemy intercontinental and submarine-launched ballistic missiles using infrared and optical sensors. Four were launched – the first unsuccessfully – by Titan IIICs in the early 1970s. The IMEWS program was a successor to MIDAS.
