The company said no one was injured in the incident, although the aircraft was a total loss. Other parts of the YFQ-42A program, including ground testing and Technology Maturation and Risk Reduction activities, continued without interruption.
A safety review found that the mishap was caused by an autopilot miscalculation involving the aircraft’s weight and center of gravity. The finding led to a software remediation effort.
The Air Force and GA-ASI conducted a joint review after the incident. Following a stringent evaluation, technical authorities endorsed the software changes and cleared the YFQ-42A to return to flight.
“We’re excited to have YFQ-42A flying again,” said GA-ASI President David R. Alexander. “It’s been said that you learn more from your setbacks than your successes.”
“We are applying what we’ve learned to our growing fleet of CCAs, as we continue building the most dependable and cost-efficient unmanned fighters in the world,” Alexander added.
The YFQ-42A is a purpose-built Collaborative Combat Aircraft platform developed as part of broader investment in next-generation semi-autonomous combat aircraft. Its modular design is intended to support rapid integration of mission systems and mission autonomy software.
GA-ASI said its software architecture has been demonstrated through multiple live flight tests on multiple airframes. The company said the architecture provides a foundation for human-machine teaming in complex combat scenarios.
The U.S. Air Force selected GA-ASI in April 2024 to build production-representative flight test aircraft for the Collaborative Combat Aircraft program. The YFQ-42A completed its first flight in August 2025.
That maiden flight validated what GA-ASI described as a “genus/species” concept for rapid, modular and low-cost uncrewed fighter development. The approach uses a common core aircraft design that can be adapted quickly for different mission sets and service requirements.
