59--MARK XIIA Mode 5

The Air Force plans to upgrade its Air Traffic Control Radar Beacon System (ATCRBS) Identification Friend or Foe (IFF) Mark XII system to the Mark XIIA version, incorporating the next-generation secure IFF Mode 5 and Mode S capabilities. This upgrade aims to enhance surveillance and identification by implementing secure communication modes that comply with international standards, including EUROCONTROL requirements. Mode S Elementary Surveillance is already being fielded using equipment from the ESC/GAT ID/IQ catalog, and the Air Force intends to begin deploying Mode 5 by fiscal year 2008 to align with ongoing Mode S enhancements and cryptographic modernization efforts. This contract opportunity, designated as "59--MARK XIIA Mode 5," was posted in early 2004 as a presolicitation with the solicitation number FA8707-04-R-0006. Although specific details such as the place of performance and point of contact are not provided, the contract focuses on supporting the Air Force’s transition towards more secure and interoperable IFF systems within their radar infrastructure. This modernization effort is vital to maintaining effective air traffic control and defense identification capabilities in coordination with international aviation surveillance frameworks.
