MIDAS Series III Infrared Sensor

Infrared sensor with black and white checkered cone with a ring mount.

Aerojet ElectroSystems built this Series III infrared sensor payload for use in Missile Defense Alarm System (MIDAS) satellites. These satellites were one part of a U.S. Air Force program operational in the 1960s to provide early warning of a Soviet missile attack. The Series III was designed to detect and track the hot exhaust gases of missiles at launch and during the boost phase.
