US Air Force Completes XQ-67A Flight Test of Mission Systems and Beyond Line-of-Sight Drone Control

The Air Force Research Laboratory (AFRL) and Air Combat Command’s (ACC) Experimental Operations Unit (EOU) have flown the XQ-67A Autonomous Collaborative Platform (ACP) over the Nevada Test and Training Range with integrated sensors, mission computers, and power and thermal management hardware, AFRL announced on October 27, 2026. The sortie, flown under the Demonstration of ACP Performance and Effectiveness (Demon APE) project, also combined Beyond Line-of-Sight (BLOS) datalinks with live, virtual and constructive (LVC) simulation. AFRL did not disclose the flight date or the specific sensors carried.

The flight follows the Air Force’s June 17, 2026, award of Collaborative Combat Aircraft (CCA) Increment 1 production contracts to General Atomics Aeronautical Systems Inc. (GA-ASI) and Anduril Industries for the FQ-42A and FQ-44A. The XQ-67A sits directly upstream of that decision: GA-ASI has stated that its CCA design is based on the AFRL demonstrator. With airframes now under contract, the testbed matters for the mission systems and control layers that will govern how those aircraft fight.

XQ-67A Flight Test Pairs Mission Systems With Power and Cooling

According to AFRL, the onboard sensors, mission computers, and power and thermal management hardware were designed to work collaboratively in demanding combat environments. That combination defines Demon APE. AFRL awarded GA-ASI a sole-source Demon APE contract on January 17, 2025, following a Phase 1 award in June 2024. The government’s justification stated that the contractor would integrate specific mission systems and upgrade the vehicle to provide adequate power generation and thermal management capacity. The contract value has not been disclosed.

The focus is operational. Sensors and autonomy processors draw electrical power and shed heat, and a compact single-engine jet has limited margin for both. An uncrewed aircraft that cannot power and cool its payload cannot perform the forward sensing role that justifies its place ahead of a crewed formation.

Released specifications remain sparse: AFRL and GA-ASI have not published dimensions, weights, engine details or performance figures. The aircraft is remotely piloted but capable of autonomous flight, and the Demon APE justification stated in early 2025 that only one airframe existed. In July 2025, GA-ASI reported that the XQ-67A had flown at the High Desert Test Range in California with government reference autonomy and an active tactical datalink.

Beyond Line-of-Sight Datalinks and LVC Simulation Test Layered Command and Control

AFRL said the BLOS datalinks and LVC simulation demonstrated management of uncrewed platforms across distributed theaters through resilient, layered command and control. The laboratory did not identify the BLOS pathway used.

Both elements address CCA employment constraints. The Air Force wants Increment 1 aircraft to have a combat radius of at least 700 nautical miles, a distance at which uncrewed wingmen operating ahead of crewed fighters will fly beyond the line-of-sight coverage of ground stations. LVC simulation surrounds a single live airframe with synthetic aircraft, threats and network nodes, loading the control architecture with force densities that would be impractical to generate on the range.

Trenton White, an aerospace engineer in AFRL’s Air Warfare directorate who previously managed the Off-Board Sensing Station (OBSS) program, said the flight showed that AFRL’s autonomous architectures can reliably process and relay combat-relevant data in real-world scenarios. He tied that result to two government-owned standards. The Autonomy Government Reference Architecture (A-GRA), validated in February 2026 and integrated on both CCA prototypes, lets mission autonomy from different vendors run on different airframes. The Agile Mission Suite Government Reference Architecture (AMS GRA) applies the same vendor-agnostic logic to mission suites.

From OBSS Demonstrator to FQ-42A Dark Merlin Production

The XQ-67A originated in the OBSS program, under which AFRL awarded initial design contracts to GA-ASI and Kratos in October 2021 before the GA-ASI design advanced to flight. Designed, built, ground tested and flown in just over two years, it first flew on February 28, 2024, from GA-ASI’s Gray Butte Flight Operations Facility near Palmdale, California. It was the first aircraft built under the genus/species concept from AFRL’s Low Cost Attritable Aircraft Platform Sharing (LCAAPS) effort, in which a common core chassis supports multiple mission variants.

That chassis logic fed the YFQ-42A, which first flew on August 27, 2025, and was named Dark Merlin in February 2026. A YFQ-42A crash on April 6, 2026, paused flight testing until the aircraft returned to flight in May; the Air Force said it did not affect the production decision.

The EOU’s presence changes who flies AFRL’s testbed. Activated as a squadron-equivalent within the 53rd Wing at Nellis Air Force Base, Nevada, on June 5, 2025, the unit led end-to-end YFQ-44A operations during testing at Edwards Air Force Base, California, in April 2026, according to Anduril. “By pairing AFRL’s rapid prototyping with ACC’s operational test units, the Air Force is shortening the timeline between concept and warfighter capability,” said Col. Matthew Caspers, Department of the Air Force Deputy Technology Executive Officer for Air.

Analysis: The XQ-67A’s value no longer rests on its airframe, whose design lineage has already entered production. It rests on retiring integration risk in the layers above it: power and thermal margins for mission payloads, control links that hold across dispersed theaters, and software portability between vendors. With a primary Increment 1 mission autonomy provider due by summer 2027 and EOU flight activity expected to inform Increment 2 requirements, a single government-controlled testbed lets AFRL mature those layers outside production configuration control. AFRL has not stated whether Demon APE hardware is destined for the FQ-42A, Increment 2, or neither.

Anduril, Collins Aerospace and Shield AI entered the first of two six-month competitive rounds for the Increment 1 mission autonomy award in June, and the fiscal 2027 budget request is the first to seek CCA procurement funds. AFRL has not said how many further Demon APE flights are planned, or whether XQ-67A sorties will feed EOU tactics development alongside the FQ-42A and FQ-44A test fleets.
