The Department of Defense, specifically the Air Force's KC-135 Program Office, is seeking industry input through a Request for Information (RFI) regarding a 5G emissions filter for the KC-135 aircraft's radio altimeter. The objective is to identify potential commercial-off-the-shelf (COTS) solutions that can protect the aircraft from interference caused by 5G technology, thereby ensuring operational integrity. This initiative is crucial for maintaining a competitive advantage for warfighters and will involve a virtual Industry Day on October 3, 2024, where participants can engage in technical discussions and one-on-one sessions. Interested parties must submit their responses by September 26, 2024, and can contact Jacob Booth at jacob.booth@us.af.mil or Trae Warcup at richard.warcup.1@us.af.mil for further information.
