The Department of Defense, through the Defense Logistics Agency at DLA Aviation in Warner Robins, GA, is conducting market research to identify manufacturers capable of producing the Transfer Switch Assembly (5930-01-199-1073), part number 439505-1. This assembly is a specialized RF transfer switch used to route high-frequency signals in microwave test systems, and it is critical for ensuring compatibility with the ALQ-161 system. The government currently recognizes L3Harris Technologies, Inc. as the sole manufacturer with the necessary capabilities, as the item has not been produced since 1983, raising concerns about diminishing manufacturing sources. Interested manufacturers are encouraged to express their capabilities by emailing Daniel Gochenaur or April Walls by October 25, 2024, as the government plans to pursue Full and Open Competition for this procurement.
