ALQ-131 ECM Pod 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. Click here to return to the Cold War Gallery.
