General Atomics YFQ-42 Dark Merlin
Unmanned combat aircraft under development by General Atomics
From Wikipedia, the free encyclopedia
The General Atomics YFQ-42 Dark Merlin is an unmanned combat aerial vehicle (UCAV) currently under development by General Atomics Aeronautical Systems. The aircraft is one of the winning designs for Increment I of the United States Air Force's Collaborative Combat Aircraft (CCA) program and is intended to augment crewed fighter aircraft such as the F-22 Raptor, F-35 Lightning, and the planned Boeing F-47 fighter for air-to-air missions through manned-unmanned teaming (MUM-T).[2]

Development and design
The YFQ-42 is a member of General Atomics "Gambit" family of UCAVs and derived from the company's XQ-67A Off-Board Sensing Station demonstrator built for the Air Force Research Laboratory.[3][4] The design was selected as one of the two winners of the Increment I CCA alongside the Anduril YFQ-44.[5]
A mockup of the design was showcased during a September 2024 Air Force conference; the aircraft's configuration is similar to the XQ-67A but modified for greater speeds and fighter-like maneuverability, with the airframe having an elongated fuselage with slender wings, a dorsal-mounted inlet, a single engine, V-tails, and internal weapons bay. Planned armament is two AIM-120 AMRAAMs.[6][7] The design is expected to provide the USAF with "affordable mass" to augment its crewed fighters in air-to-air missions. Its low cost nature, while not attritable, enables users and commanders to take greater risks with them.[8]
The aircraft received its formal designation during the 2025 Air & Space Forces Association symposium. On 27 August 2025, the United States Air Force and General Atomics announced the YFQ-42A had begun its flight testing.[9]
On 23 February 2026, in a statement from General Atomics, the YFQ-42 was named "Dark Merlin", named after a type of falcon.[2][10]
Flight Test Mishap
On 6 April 2026 a YFQ-42A crashed during a mishap shortly after takeoff, resulting in the total loss[11] of an aircraft and causing delays in flight testing activities.[12][13] Flight testing resumed on 21 May 2026.[11]
The cause was determined to be an autopilot miscalculation of the aircraft weight & center of gravity.[11]
