“A thorough safety review isolated the cause to an autopilot miscalculation for the weight and center of gravity of the aircraft, prompting a software remediation,” General Atomics said in a news release.
The mishap: April 6 crash and immediate consequences
On April 6, a YFQ-42A “Dark Merlin” collaborative combat aircraft crashed at General Atomics’ company airport in California. No one was injured, but the company described the aircraft as a “total loss.” The mishap paused flight testing of the company’s production-representative collaborative combat aircraft (CCA) while General Atomics and the Air Force conducted a joint investigation.
Investigation findings and the software remediation
The joint probe identified a software problem: an autopilot miscalculation tied to the aircraft’s weight and center of gravity. General Atomics said the issue prompted “a software remediation,” and that the company continued ground testing and other evaluations while flight testing was on hold. Following what the company characterized as a “stringent evaluation,” technical authorities endorsed the software changes and the YFQ-42A was cleared to fly again.
Return to flight and company statements
Nearly seven weeks after the mishap, General Atomics announced that flight testing had resumed. C. Mark Brinkley, a General Atomics spokesperson, said testing resumed on Wednesday. Company leadership framed the setback as a learning opportunity: General Atomics President David R. Alexander said, “It’s been said that you learn more from your setbacks than your successes,” adding that the company is “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.”
Program context: competition, procurement timing, and budget
The YFQ-42A is one of several production-representative CCAs being built for the Air Force’s drone wingman competition. General Atomics is competing against Anduril and Northrop Grumman for the service’s business. An Increment 1 production decision is expected before the end of September, and 2027 budget documents released last month show the Air Force is requesting nearly $1 billion to buy its first CCAs.
How the Air Force and Anduril responded
Air Force Col. Timothy Helfrich, portfolio acquisition executive for fighters and advanced aircraft, framed the episode as part of an acquisition and test approach that accepts risk in testing to avoid operational risk. In an emailed statement he said, “The USAF and General Atomics response to the YFQ-42 mishap validates our approach to accept acquisition/test risk instead of operational risk allowing us to accelerate the program towards fielding.” Helfrich added that the service “pushed the envelope, identified a risk, learned from the data, and have cleared the YFQ-42A to return to flight.”
Helfrich also noted that the pause on General Atomics’ platform did not stall CCA progress: the service’s Experimental Operations Unit at Edwards Air Force Base flew several sorties with Anduril’s YFQ-44A Fury the same week General Atomics had paused test flights. “Despite the pause on one platform, we executed this critical exercise that same week using the YFQ-44A to validate core operational and deployment concepts,” Helfrich said, adding that a resilient, multi-vendor approach kept “overall CCA progress” moving.
What this means for General Atomics, the Air Force, and Anduril
- General Atomics: The company says it will apply lessons from the mishap across its growing CCA fleet while resuming flight testing and continuing ground evaluations; the firm emphasizes reliability and cost-efficiency as it advances its Dark Merlin design.
- The Air Force: Col. Helfrich’s remarks underscore a test regimen that accepts acquisition/test risk to accelerate fielding, and the service is proceeding with multi-vendor exercises even when a single platform is paused.
- Anduril: With the Experimental Operations Unit flying the YFQ-44A Fury during the same week, Anduril’s platform was used to validate core operational and deployment concepts while other platforms were temporarily grounded.
The immediate technical fix is described in unambiguous terms: an autopilot calculation tied to weight and center of gravity was corrected, technical authorities endorsed the software changes, and the YFQ-42A returned to flight. Program milestones remain concrete and near-term — an Increment 1 production decision expected before the end of September and a nearly $1 billion procurement request in the 2027 budget documents released last month — making the next months a pivotal interval for both testing and acquisition.
