“The ALQ-131 is an advanced electronic countermeasures (ECM) pod designed to provide an aircraft self-protection against radar threats. The ALQ-131 accomplishes this by responding with a combination of noise, repeater or transponder electronic jamming techniques. The pod weighs 600 pounds, with modular design for multiple frequency band capability. It has an ability to be quickly re-programmed against changing threats. The ALQ-131 is used by A-10, F-16 and F-111 aircraft. Other ECM pod systems being used by USAF aircraft include the ALQ-119 and ALQ-184.” (From the National Museum of the Air Force.)
“The AN/ALQ-131 Electronic Countermeasures (ECM) pod is the most successful ECM system ever built. Northrop Grumman has fielded more than 1,600 ALQ-131 pods, which used state-of-the-art technology to successfully protect aircrews and aircraft in every conflict since becoming operational.
To stay ahead of new and emerging threats with advanced capabilities, Northrop Grumman revolutionized the ALQ-131 through the insertion of digital technology. The architecture is a derivative of technologies from the most capable fighter aircraft, including F-16 Block 60 and F-35 Joint Strike Fighter. This upgrade does not change the pod’s size, weight or power requirements; neither does it induct any mandatory aircraft modification.” (From Northrop Grumman website.)
