Marines Select GA-ASI YFQ-42A For MUX TACAIR Collaborative Combat Aircraft Evaluation
The U.S. Marine Corps has selected General Atomics Aeronautical Systems’ YFQ-42A platform for evaluation under its Marine Air-Ground Task Force Uncrewed Expeditionary Tactical Aircraft (MUX TACAIR) Collaborative Combat Aircraft (CCA) program, marking a key step in testing uncrewed combat aircraft working with crewed fighters.
USMC Moves Forward With Uncrewed Aircraft Evaluation
Under the contract, GA-ASI will integrate a Marine Corps mission kit, supplied by the government, onto its YFQ-42A uncrewed aircraft to serve as a surrogate testbed. The work focuses on assessing how autonomous aircraft equipped with advanced sensor and mission systems operate within Marine Air-Ground Task Force (MAGTF) expeditionary operations and alongside manned fighters.
The Marine Corps contract calls for rapid development of autonomy for the government-provided mission kit. That suite is expected to include software-defined systems and sensors capable of delivering both kinetic and non-kinetic effects. Evaluations will feed into future MUX TACAIR capability decisions.
Platform Background and Integration Goals
The YFQ-42A was first flown in August 2025 during testing under the U.S. Air Force’s Collaborative Combat Aircraft program, where it was chosen in 2024 to build production-representative flight test articles. Its design follows a modular “genus/species” concept that lets a common airframe integrate different mission systems rapidly.
GA-ASI brings its autonomy and uncrewed aircraft systems experience to the USMC effort. The company says its autonomy architecture, backed by multiple live flight tests, will help form the foundation for human-machine teaming in complex contested environments.
Mike Atwood, vice president of advanced programs for GA-ASI, noted that the company’s autonomous systems in service today and its integration expertise position the firm to provide an affordable CCA test solution that enhances Marine Air-Ground Task Force effectiveness.
Broader MUX TACAIR Context
The Marine Corps launched the MUX TACAIR program to explore how uncrewed aircraft can support and complement crewed tactical aviation, including integration with F-35s and other fighters. The effort aligns with wider Department of the Air Force CCA initiatives that emphasize crewed-uncrewed teaming to extend sensor reach and mission flexibility in contested airspace.
Northrop Grumman and Kratos also received awards related to the MUX TACAIR effort, with a team focusing on an XQ-58 Valkyrie-based platform to integrate Marine-specific systems.
What Comes Next
Over the coming months, the Marine Corps and GA-ASI will work on mission kit integration and autonomy development, with evaluation flights and testing planned as part of MAGTF operational experimentation. Insights from this phase will help inform future CCA acquisition and operational plans for Marine aviation.
