Hardware for the ALR-56s, developed in the 1980s and early 1990s, “has been upgraded extensively to extend their usable life spans,” according to the J&A for the ALR-56. “The systems have undergone continuous modernization through circuit card redesigns to address parts obsolescence and the integration of Line Replaceable Units for enhanced capability. Each upgrade has incorporated new or revised TPS [Test Program Sets].”

“BAE Systems’ unique expertise has been instrumental in resolving past challenges and implementing improvements, resulting in increased workforce efficiency,” the Air Force said in the J&A. “This follow-on effort necessitates BAE Systems’ continued support in addressing target hardware DRs, resolving hardware/TPS anomalies, and ensuring test verticality. The increasing age of these systems has led to a rise in DRs, negatively impacting the supply chain by requiring the removal of repairable assets for investigation. This acquisition is therefore essential to ensure the uninterrupted sustainment of this highly specialized system.”

In 2024, BAE Systems said that it was meeting commitments to supply upgraded ALR-56Ms for Air Force C-130Js under a 10-year, $495 million contract awarded by the Defense Logistics Agency in September 2019.
