The AN/ALE-50 towed decoy system is an electronic countermeasure system designed and manufactured by Raytheon to protect multiple US military aircraft from air-to-air and surface-to-air radar-guided missiles. The ALE-50 towed decoy system is an anti-missile countermeasures decoy used on U.S. Air Force, Navy, and Marine Corps aircraft, and by air forces of other countries. The system is manufactured by Raytheon Space and Airborne Systems at its facility in Goleta, California. The ALE-50 system consists of a launcher and launch controller installed on the aircraft, with one or more expendable towed decoys. Each decoy is delivered in a sealed canister with a ten-year shelf life.
