US Air Force Launches First Uncrewed Fighter Jets — YFQ-42A and YFQ-44A Begin Flight Testing

US Air Force Unveils First Uncrewed Fighter Jets in CCA Program

On March 3, 2025 the US Air Force formally designated two jet-powered unmanned fighters — YFQ-42A and YFQ-44A — under its newly launched Collaborative Combat Aircraft (CCA) initiative.

Less than a year later, both prototypes have taken to the skies: YFQ-42A achieved its maiden flight in August 2025, followed by YFQ-44A on October 31, 2025.

Together these jets mark the first time the service has fielded uncrewed platforms with a formal “fighter” designation.

Background: An Evolving Vision for Air Combat

The CCA program emerged as part of the Air Force’s broader push toward the next generation of air dominance, blending human-piloted aircraft with autonomous drones to expand mission flexibility and survivability in contested environments.

Under the official US military aircraft designation system, the “Y” prefix denotes prototype status, “F” indicates a fighter mission, and “Q” signals an uncrewed system. Thus YFQ-42A and YFQ-44A are the first uncrewed jets to carry a formal fighter label.

The aim is to complement existing frontline aircraft — such as the F-35 Lightning II — with swarms of lower-cost, high-performance drones that can assume risky roles, extend sensor coverage, conduct electronic warfare or strike missions, and multiply combat mass without putting pilots in danger.

YFQ-42A and YFQ-44A: What We Know

YFQ-42A (General Atomics)

• Built by General Atomics Aeronautical Systems (GA-ASI), the YFQ-42A traces its roots to the earlier XQ-67A demonstrator from the Air Force Research Laboratory’s Off-Board Sensing Station program.
• The jet features a stealth-informed design with a streamlined fuselage, dorsal-mounted air intake, and twin canted V-tails. It carries weapons in internal bays — including air-to-air missiles such as the AIM-120 AMRAAM.
• Its architecture is modular, built to support different mission profiles including air-to-air combat, strike, electronic warfare, and surveillance — depending on payload and configuration.
• According to GA-ASI, the design provides “affordable mass” — lower unit cost and higher deployability than manned fighters — making it suitable for high-risk missions where attrition is possible.
• Flight testing kicked off in August 2025 at a classified site in California.

YFQ-44A (Anduril “Fury”)

• Developed by Anduril Industries, YFQ-44A — internally known as “Fury” — represents a clean-sheet, jet-powered combat drone design. Anduril acquired the original design from Blue Force Technologies in 2023.
• The aircraft incorporates swept trapezoidal wings, a chin-mounted air inlet, a cruciform tail, and external hardpoints. It relies on a Williams FJ44-4M turbofan engine, giving thrust around 4,000 lbf (roughly 17.8 kilonewtons).
• Estimated performance puts it at near-supersonic speed (around Mach 0.95) at altitudes up to 50,000 feet, and capable of withstanding up to 9 g maneuvers.
• On Oct 31, 2025, YFQ-44A completed its first semi-autonomous flight at Southern California Logistics Airport. During the flight the aircraft carried out its mission plan, managed flight control and throttle autonomously, and returned to land under operator supervision.
• Anduril says the development from clean-sheet design to first flight took just 556 days, showing a rapid development pace unusual in modern military aviation.

What This Means: Redefining Air Combat

With the introduction of YFQ-42A and YFQ-44A, the Air Force is signalling a shift toward manned-unmanned teaming. These drones are not meant just as remote-controlled recon platforms, but as fully capable combat assets that can fly alongside — or ahead of — crewed fighters.

The fighter designation alone marks a doctrinal change. According to Air Force leadership, the move reflects a broader transition to what some call “affordable mass” — deploying larger numbers of cheaper, attritable platforms rather than fewer high-cost, high-risk manned jets.

Additionally, these uncrewed fighters could expand mission flexibility. They might handle dangerous strike or suppression tasks, act as decoys, perform electronic warfare, or extend sensor and weapons coverage — all while reducing risk to pilots.

By pairing with existing fighters such as F-35, the drones could offer significant force multiplication — potentially enabling one pilot to control multiple unmanned wingmen in future combat formations.

What’s Next: Testing, Production, Planning

Both YFQ-42A and YFQ-44A remain in a developmental phase. After their first flights, the next steps will involve more flight tests, integration trials with manned fighters, and evaluation of autonomy, weapons delivery, sensor packages, and survivability in contested environments.

If testing proceeds successfully, the Air Force may move toward production later in the decade under the CCA program’s Increment 1 deliverables. Observers expect future CCAs may number in the hundreds — or possibly thousands — providing a radically expanded air-combat force structure.

Implications

The successful flight tests of YFQ-42A and YFQ-44A mark the start of a new chapter in U.S. airpower. As these uncrewed fighters advance through evaluation and integration, they could significantly reshape how air combat is fought — blending human-led decision-making with autonomous execution, increasing force flexibility, and lowering risk to pilots.

If adopted at scale, CCAs may shift military investment away from expensive, high-end manned jets toward fleets of attritable, capable drones that deliver combat mass with lower cost per unit and higher operational risk tolerance.
