The F-35 Joint Program Office, U.S. Air Force, and Lockheed Martin have started integrating the Automatic Ground Collision Avoidance System (Auto-GCAS) onto Air Force F-35As in the fleet. The joint government and industry team successfully fielded the technology seven years earlier than previously planned.

"This is a great day for the warfighter, as the Auto-GCAS is a proven system that is long overdue," said Lt. Gen. Eric Fick, F-35 program Executive Officer. "Expediting this life-saving technology into the F-35 across the global fleet will bring more warfighters home. Over the service life of the F-35 fleet, having Auto-GCAS is estimated to prevent more than 26 ground collisions from happening. It is indeed a remarkable achievement in aeronautics which will improve the performance, efficiency, and safety of the F-35. The time and effort expended to deliver this critical warfighting capability is worth it—it will save lives."

Originally developed for the F-16 in partnership with NASA and the Air Force Research Laboratory, Auto-GCAS uses terrain mapping, geolocation, and automation to detect and avoid potential ground collisions. When the program recognizes imminent impact, it will prompt the pilot to take action. If the pilot is unresponsive, Auto-GCAS assumes temporary control to divert the aircraft out of harm's way and then returns control of the aircraft to the pilot once on a safe trajectory.

The system has been operating successfully aboard the F-16 for more than five years and has already been credited with saving eight F-16 pilots' lives since 2014.

"Early integration of Auto GCAS in the F-35 is bringing game changing safety capability to a rapidly growing fleet. It couldn't have come at a better time as we near full rate production resulting in more aircraft and pilots exposed to rigorous missions," said Lt. Col. Darren Wees of the Air Force's F-35 Integration Office.

Auto-GCAS was originally slated for delivery in the 2026 timeframe. To accelerate the technology, Air Force Research Laboratory and Lockheed Martin conducted positive feasibility studies, and the F-35 Joint Program Office and Lockheed Martin then implemented an agile approach to develop the technology for integration on the F-35. The 412th Test Wing at Edwards Air Force Base then completed a rigorous flight testing program to validate its performance and safety, which led to the wing's formal recommendation to field Auto-GCAS aboard the F-35.

U.S. Air Force F-35As are the first to receive Auto-GCAS, and the system will next be integrated aboard the F-35B and F-35C variants. The Auto-GCAS team was recently recognized with the National Aeronautic Associations' 2018 Robert J. Collier Trophy, and received the prestigious award in June 2019.
