The AFLCMC/WLNK agency requires 217 AN/APX-119 Transponders (P/N: 4079100-0541) at a firm-fixed price. These transponders enable Mobility Air Force (MAF) aircraft to utilize existing Traffic Alert and Collision Avoidance System (TCAS) capabilities while selectively inhibiting

This Statement of Work (SOW) outlines requirements for procuring AN/APX-119 Transponders (P/N: 4079100-0541) for the Mobility Air Force (MAF) to upgrade C130J fleets. These transponders enable Traffic Alert and Collision Avoidance System (TCAS) capabilities while selectively inhibiting

This Request For Information (RFI) is for market research to identify potential sources for procuring the C-130J Avionics Identification Friend of Foe (IFF) AN/APX-119 Transponder (NSN 5841-01-693-3952, P/N 4079100-0541). The government seeks manufacturing services for 217 units over a two-year contract through FY27. This upgrade addresses AMC 22-042, UON 25-008, and mitigates Diminishing Manufacturing Sources and Material Shortages (DMSMS) for the legacy IFF Transponder. The AN/APX-119 enables TCAS capabilities while inhibiting "open air" position reporting systems. The RFI encourages both large and small businesses, including joint ventures, to submit capability surveys by December 1, 2025. Responses should detail business information, general capabilities (e.g., past experience, classified material handling, quality assurance), manufacturing capabilities (e.g., procedures, capacity, inventory), and engineering services. The government does not own or have access to data for these commercial items and will not reimburse participants for survey expenses.
