Operational Suitability Verified for F-16 Application
Enhanced Encrypted Communications and Cybersecurity
Initial Delivery of 90 Units Planned for This Year

BAE Systems announced on October 1 that its new Identification Friend or Foe (IFF) equipment, the AN/APX-127(V)1 Combined Interrogator Transponder (CIT), has obtained AIMS certification for application on United States Air Force F-16 fighter jets. AIMS certification is a system used to verify the operational suitability of IFF equipment under the interoperability standards between the United States and the North Atlantic Treaty Organization (NATO).

The AN/APX-127(V)1 is a product that integrates the interrogator and transponder into a single device. By applying an open-systems architecture, it allows software upgrades without hardware replacement. It is designed according to the same specifications as existing AN/APX-113(V), AN/APX-125(V), and AN/APX-126(V) units, enabling direct replacement of legacy equipment.


The new equipment supports encrypted data communications by acquiring AIMS Mark XIIB certification in both Mode S and Mode 5. It features a dedicated receive channel that enables reception of Mode 5 Level 2 signals and Automatic Dependent Surveillance-Broadcast In (ADS-B In) signals, improving pilot situational awareness. The latest encryption and cybersecurity standards have also been implemented.


Seth Guannu, Program Director of Combat Identification Products at BAE Systems, stated, "We are focused on supporting the missions of both current and future platforms through next-generation IFF technology," adding, "The new equipment will deliver enhanced security and real-time information in a variety of threat environments."



To date, BAE Systems has supplied approximately 1,500 interrogators, 6,000 combined interrogator transponders, and 16,000 transponders. The AN/APX-127(V)1 is produced at facilities in Greenlawn, New York, and Austin, Texas, with plans to deliver an initial batch of 90 units this year.
