The AN/ALE-50 Towed Decoy System was developed by Raytheon to protect multiple US military aircraft from radar-guided missiles. The AN/ALE-50 Towed Decoy System is an anti-missile countermeasures decoy system used on multiple U.S. Air Force, Navy, and Marine Corps aircraft, and by certain non-United States air forces. 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 (usually on a wing pylon), and one or more expendable towed decoys. Each decoy is delivered in a sealed canister and has a ten-year shelf life.
