The Department of Defense, specifically the Department of the Air Force, is conducting market research to identify potential sources for the procurement of the ALR-56M Radio Frequency (RF) Switch (NSN 5985-01-512-9801EW), which is critical for military applications, particularly in the F-16 C/D and C-130J A/C platforms. The government seeks contractors with the expertise and capabilities to provide depot-level testing and manufacturing of this RF switch, which is currently supplied exclusively by Herley Industries, Inc., due to unique technical data rights that complicate sourcing from alternative manufacturers. Interested parties must maintain facilities for handling classified materials and submit their capabilities and past experiences by September 19, 2024, to Michael Wensjoe or Kylie Ordoyne via email, as participation in this survey does not guarantee future contract awards and the government will not reimburse any associated expenses.
