General Atomics Aeronautical Systems (GA-ASI) has returned its YFQ-42A Collaborative Combat Aircraft prototype to flight testing, roughly six weeks after a mishap that destroyed one of the airframes built for the US Air Force’s drone-wingman competition.
The company announced the resumption in a statement dated May 21, 2026. Flight operations had been paused since April 6, 2026, when a YFQ-42A crashed shortly after takeoff at a GA-ASI airport in the California desert. No one was injured, but the aircraft was a total loss.
Autopilot miscalculation pinpointed
A joint safety review conducted by GA-ASI and the US Air Force traced the mishap to an autopilot miscalculation of the aircraft’s weight and center of gravity, the company said.
GA-ASI implemented a software remediation, which technical authorities endorsed before clearing the prototype to fly again. Ground testing and other Technology Maturation and Risk Reduction activities continued during the pause, according to the company.
“It’s been said that you learn more from your setbacks than your successes,” GA-ASI President David R. Alexander said in the announcement. “We are applying what we’ve learned to our growing fleet of CCAs.”
A consequential pause for the CCA competition
The interruption came at a sensitive moment for the US Air Force’s Collaborative Combat Aircraft (CCA) program. The YFQ-42A is competing against Anduril Industries’ YFQ-44A Fury, which conducted its maiden flight in late 2025, with an initial production decision expected in fiscal year 2026.
GA-ASI was selected in April 2024 to build production-representative flight test articles for CCA Increment 1. Its YFQ-42A completed its first flight in August 2025 at Gray Butte, California, validating what the company describes as a ‘genus/species’ approach to modular, low-cost uncrewed fighter development. GA-ASI is also positioning the platform for European export, with final assembly planned at GA-ATS in Oberpfaffenhofen, Germany.
