The ALQ-131 electronic countermeasure (ECM) system has provided the United States Air Force with proven self protection for many of its tactical fighter aircraft. The reliability and maintainability improvements of the ALQ-131 Block II has produced a system with a mean time between failures (MTBF) of 120 to 180 hours and greater than 95 percent availability for the 390 systems in theater during the Persian Gulf war. None of the aircraft carrying the ALQ-131 Block II was shot down, and at least 60 percent of the ALQ-131 Block IIs never needed maintenance and stayed on the aircraft throughout the air campaign. Due to classic reliability and maintainability approaches, the ALQ-131 has reached this high standard, but improved understanding of the environment experienced by the system will provide the next steps in reliability improvements. The capture of measured response data, as detailed in this paper, will provide a basis for developing life cycle and customer warranty tests which will guarantee to the customer that the ALQ-131 system will continue to perform reliably from takeoff to landing, and from mission to mission through the life of the system.
