AN/ALQ-156A MAWS Missile Approach Warning System

The Army's AN/ALQ-156(V)1 Missile Approach Detector / Missile Approach Warning System (MAWS) an airborne radar system carried on the CH-47D which is designed to warn of a threat missile actually targeting the aircraft, thus enabling the effective employment of evasive maneuvers and electronic warfare and infrared countermeasures. It was developed as part of the Integrated Defensive Avionics Program (IDAP), along with the AN/ALE-50. The AN/ALQ-156(V)2 Missile Approach Detector provides protection for the EH-60A, RC-12, C-23B aircraft, and the AN/ALQ-156(V)3 is used on the OV-1D.

The AN/ALQ-156(V)1 Missile Approach Detector consists of a receiver/transmitter (RT), a control indicator and two identical blade antennas. The RT is equipped with a built-in-test capability for the system. The total system weight is 49.5 pounds. Upon detection of an on-coming missile, the missile detector automatically initiates a signal which triggers the M-130 General Purpose Dispenser System. The dispenser system then releases a flare to decoy the infrared missile(s) away from the aircraft. The AN/ALQ-156 and M-130 Dispenser with flares are designed to provide protection against present and near-term infrared homing missile threats.

This system has been transitioned to Communications-Electronics Command (CECOM). The program is currently in Engineering and Manufacturing Development (EMD) with work being conducted by Lockheed Martin, Nashua, NH.

The AN/ALQ-156(V)2 Missile Approach Detector is an airborne radar system which provides infrared homing protection to the EH-60A and RC-12 aircraft by detecting the approach of anti-aircraft missiles. Upon detection of an on-coming missile, the missile detector automatically initiates a signal that triggers the M-130 General Purpose Dispenser System. The dispenser system then releases a flare to decoy the infrared missile(s) away from the aircraft. The AN/ALQ-156(V)2 Missile Approach Detector and M-130 Dispenser with flares are designed to provide protection against present and near-term infrared homing missile threats. The AN/ALQ-156(V)2 Missile Approach Detector consists of a receiver/transmitter (RT), a control indicator and four identical circular horn antennas. The RT is equipped with a built-in-test capability for the system. The total system weight is 55.8 pounds.

The AN/ALQ-156(V)3 Missile Approach Detector is an airborne radar system which provides infrared homing protection to the C-23B aircraft by detecting the approach of anti-aircraft missiles. Upon detection of an on-coming missile, the missile detector automatically initiates a signal that triggers the M-130 General Purpose Dispenser System. The AN/ALQ-156(V)3 Missile Approach Detector and M-130 Dispenser with flares are designed to provide protection against present and near-term infrared homing missile threats. The dispenser system then releases a flare to decoy the infrared missile(s) away from the aircraft. The AN/ALQ-156(V)3 Missile Approach Detector consists of a receiver/transmitter (RT), a control indicator and four identical planar slot antennas. The RT is equipped with a built-in-test capability for the system. The total system weight is 63.8 pounds.
