Flight testing of an autonomous KC-135 Stratotanker may begin next year.
Boston’s Merlin Labs, Inc. and the U.S. Air Force’s 6th Air Refueling Wing at MacDill AFB, Fla., have been testing the Merlin Pilot system to provide autonomy and automation for the KC-135 tanker to reduce aircrew and allow crew members to focus on critical mission tasks.
In February, Merlin said that it had signed a multi-year Cooperative Research and Development Agreement with Air Mobility Command (AMC) and Air Force Materiel Command to develop and integrate the Merlin Pilot on the KC-135 to inform the Next Generation Air Refueling System and “pave the way for autonomous uncrewed operations of the KC-135–an unprecedented new capability for AMC and the USAF.”
Merlin said on Monday that its “airworthiness plan for the Merlin Pilot KC-135 testing has been accepted by the United States Air Force.”
“This joint USAF and Merlin project will evaluate the viability of scaling the Merlin Pilot to large transport aircraft, especially its innovative AI capabilities,” the company said. “Achieving this milestone demonstrates that Merlin’s system engineering processes are consistent with the airworthiness standards set by the USAF, and allows Merlin to progress towards aircraft integration, design completion, and testing operations.”
Air Force acceptance of the Merlin Pilot KC-135 airworthiness plan “is the first major milestone to be executed under this collaboration, and lays the groundwork for the Merlin Pilot’s certification basis and eventual Military Flight Release (MFR),” Merlin said. “Integrating the Merlin Pilot on the KC-135 kickstarts Merlin’s Part 25 airworthiness programs and is material to continued advancements on this class of aircraft. Merlin is targeting the end of 2024 for its design completion, with ground testing, flight testing, and demonstrations to occur in 2025.”
In June, the company said that it had received a $105 million contract from U.S. Special Operations Command to provide advanced automation for the Air Force C-130J airlifter by Lockheed Martin as a step toward such features for other special operations forces (SOF) fixed wing aircraft over the next five years.
Merlin said that it has had a two-year partnership with the Air Force and that this summer’s C-130J contract will provide advanced automation design and integration on the C-130J; ground testing; Test Readiness Review and flight test; full takeoff to landing demonstration; and integration on other SOF aircraft.
