The U.S. Air Force is accelerating its CCA drone program to support the F-47, but their cost, range, and stealth capabilities remain risky bets.
The US Air Force is significantly accelerating its CCA combat drone program, short for Collaborative Combat Aircraft. The stated goal is now to deploy more than 150 autonomous aircraft by fiscal year 2031. These drones are intended to support the F-35, F-22, F-15EX, and especially the future F-47, developed under the NGAD program. Two prototypes are drawing particular attention: General Atomics’ YFQ-42A Dark Merlin and Anduril’s YFQ-44A Fury. Testing is progressing rapidly, with autonomous flights, weapons integration tests, and an open software architecture. But the gamble remains precarious. If these drones become too sophisticated, too stealthy, and too expensive, they will lose their raison d’être. Their strategic value rests on a delicate balance: powerful enough to survive in contested airspace, yet affordable enough to be mass-produced.
The CCA Program Moves from Concept to Operational Planning
The U.S. Collaborative Combat Aircraft program is no longer just an experiment with futuristic drones. It is entering a more concrete phase. The U.S. Air Force has informed Congress of its intention to acquire more than 150 CCAs by fiscal year 2031. This figure marks a significant shift. For several years, Washington had primarily discussed a conceptual goal of up to approximately 1,000 collaborative drones, based on a ratio of about two drones for every advanced fighter jet. Now, the discussion is shifting toward an initial fleet that is funded, tested, and integrated into the force structure.
The timeline is tight. Prototypes are already flying. Evaluations are no longer limited to the airframe or engine. They also cover autonomy, control interfaces, weapons integration, maintenance, deployment, and operational procedures. The U.S. Air Force wants to avoid the classic pitfall of military programs: spending fifteen years perfecting a technology before deploying it. Here, it is testing the aircraft, the software, the doctrine, and the organization in parallel.
The CCA addresses a simple problem. Modern fighter jets have become very expensive. There are also few of them. Pilots take a long time to train. Missile stocks can be depleted very quickly in a high-intensity conflict. In the Pacific, facing China, distances are vast and air defenses are dense. An F-35 or a future F-47 cannot do everything on its own. It needs remote sensors, jammers, decoys, communication relays, and platforms capable of carrying additional missiles.
This is precisely the role expected of CCA. They must increase airpower without proportionally increasing the number of pilots, manned aircraft, and vulnerable bases.
The F-47 becomes the center of a system, not just a new aircraft
The F-47 is presented as the U.S. Air Force’s future sixth-generation fighter.
It is intended to eventually replace the F-22 Raptor, of which only 187 production units were built. The F-47 will not merely be a more modern stealth fighter. It is intended to become the central hub of a broader air system, in which CCA drones can fly ahead, on the flanks, or in support.
The budget highlights the program’s significance. U.S. budget documents allocate over $5 billion for research, development, testing, and evaluation of the F-47 in 2027, compared to approximately $3.45 billion in 2026. Projections reach nearly $5.25 billion in 2028. Added to this is the NGAP engine program—short for Next-Generation Adaptive Propulsion—with over $513 million requested in 2027 and a projection of nearly $906 million in 2028.
These figures make one thing clear: the F-47 is not a secondary program. It already consumes a budget comparable to major U.S. strategic programs. But it is arriving in a tight budgetary environment. The B-21 bomber, Sentinel intercontinental missiles, munitions, missile defense, and nuclear modernization all weigh heavily on the Pentagon’s budget. The F-47 must therefore prove that it can deliver decisive superiority without becoming an uncontrollable financial drain.
CCAs are supposed to solve part of this problem. They should allow the F-47 to be fewer in number but more effective. A manned fighter could command or coordinate multiple drones. These drones could take risks that would be avoided with a pilot on board. They could also expand the detection range, overwhelm the enemy, or fire missiles from a forward position. The F-47 thus becomes less of an isolated aircraft and more of a stealthy conductor.
The YFQ-42A Dark Merlin focuses on endurance and open architecture
The first major competitor in the CCA Increment 1 program is the YFQ-42A Dark Merlin, developed by General Atomics. It conducted its first flight tests in California in 2025. The U.S. Air Force states that the aircraft contributes to the evaluation of airworthiness, flight endurance, and mission systems integration.
The Dark Merlin is designed as a modular platform. General Atomics draws on its experience with MALE drones, but the CCA is not a modernized MQ-9. It is a jet-powered drone, designed to operate alongside fighter jets in more dangerous environments. Its likely roles include advanced surveillance, passive detection, carrying air-to-air missiles, data relay, and electronic warfare.
The challenge is not just aerodynamic. It is software-related. The U.S. Air Force is promoting an open architecture called the Autonomy Government Reference Architecture. Its goal is to prevent a drone from being locked into a single software provider. In short, Washington wants to be able to install different algorithms, sensors, or autonomy modules on different airframes. This is a crucial point. If each drone becomes a closed system, the program will lose speed, competitiveness, and flexibility.
This approach is more reminiscent of smartphones than traditional aircraft. The airframe must fly. The engine must be reliable.
But value will also lie in updates, mission applications, targeting algorithms, communication modes, and the ability to quickly integrate new sensors.
The YFQ-44A Fury embodies the new U.S. military industry
The second prototype is Anduril’s YFQ-44A Fury. Its first flight was announced for October 2025. The drone flew in semi-autonomous mode. According to Anduril, it can manage its flight controls and thrust without direct manual piloting, then land with limited human intervention. This point is important. The goal is not to build a conventional remotely piloted drone. The goal is to build a system capable of executing a mission with a high degree of autonomy, under human supervision.
Anduril also represents an industrial shift. The company comes from the world of defense technology and software, not the old traditional aerospace complex. It relies on rapid production, short cycles, high digital integration, and its Lattice autonomy system. This model appeals to the Pentagon, which wants to accelerate programs and reduce dependence on a few major historical prime contractors.
The YFQ-44A Fury is often described as closer to a small cockpit-less fighter than a slow drone. It must be capable of accompanying fast aircraft, operating at high altitudes, and performing tactical maneuvers. This ambition comes at a price. The faster, stealthier, more maneuverable, and survivable a UAV becomes, the closer it gets to the cost of a piloted aircraft. This is the program’s central paradox.
The U.S. Air Force wants a drone robust enough to survive in a sky protected by radars, surface-to-air missiles, and enemy fighters. But it doesn’t want to pay for a second unmanned F-35. The Fury is therefore as much an industrial test as a military one. It must demonstrate that a new generation of manufacturers can produce faster, better, and cheaper.
Autonomy remains the core technical risk
The word “autonomous” is often misunderstood. A UCAV must not decide on its own to wage war. The U.S. Air Force emphasizes that a human retains authority over firing decisions. But between takeoff, navigation, formation flying, detection, threat avoidance, target prioritization, and returning to base, autonomy will have to handle a massive number of situations.
This is where the program gets difficult. A loyal wingman drone must understand the pilot’s intent, maintain formation, react to a communication failure, avoid a collision, preserve its stealth, manage its fuel, and interpret an electronic warfare environment. It must do so without overwhelming the human pilot. If the pilot must constantly correct three drones, the operational benefit disappears.
The challenge is also legal and doctrinal. In congested airspace, communications can be jammed. What does the CCA do if the link with the F-47 is lost? Does it continue the mission? Does it return to base? Does it change altitude? Does it fire only upon prior authorization? These questions are not theoretical. They determine the actual use of drones in combat.
Autonomy is expensive, as it must be tested in thousands of scenarios. It is not enough for a drone to simply be able to fly. It must be reliable in the face of adversaries who will attempt to deceive it, jam it, or hack its communications. Software robustness can become as important as radar stealth.
Stealth Can Turn an Affordable Drone into an Overly Expensive Aircraft
The main obstacle to the CCA program lies in a contradiction. To be useful in a conflict against China or Russia, the drone must survive in a highly contested environment. This requires stealth, specialized materials, careful antenna integration, optimized shapes, internal cargo bays, and a reduced infrared signature. But all of this is expensive.
A drone with low stealth capabilities may be useful as a decoy or as a disposable platform. But it will struggle to survive near enemy defenses. A highly stealthy drone will be more effective, but it will become more expensive to produce, repair, and maintain. The U.S. Air Force wants to break free from this dilemma. It is no longer talking solely about “expendable” drones—that is, drones meant to be sacrificed. It is seeking aircraft that can be deployed in higher-risk situations than a manned aircraft, but that won’t be discarded after every mission.
This distinction is essential. The CCA is not a reusable cruise missile. Nor is it an unmanned F-35. It must occupy a middle ground. This space is very narrow. If it’s too simple, it will be shot down. If it’s too complex, it will be too rare. If it’s too cheap, it will be vulnerable. If it’s too high-performance, it will be over budget.
The real question, therefore, is not whether the United States can build an autonomous combat drone. It can. The real question is whether it can build hundreds of them, maintain them, update them, arm them, and lose them if necessary without breaking the economic model.
Cost becomes the deciding factor for the program
The key word for the CCA is affordable mass production. The U.S. Air Force wants to restore its fleet size. It cannot do so with manned fighters alone. Fifth- and sixth-generation aircraft are too expensive, require too much maintenance, and impose too many human constraints. CCAs must therefore offer more sensors, more missiles, and more tactical options at a lower cost.
But the actual cost remains unclear. U.S. officials are avoiding giving a credible final price until requirements are finalized. This is prudent. Military programs often spiral out of control when capabilities are added during development. A drone initially designed to be affordable can be upgraded with better stealth, a more powerful engine, a more secure link, a more advanced radar, and a more complex payload bay—and end up costing much more than anticipated.
The danger is well known. The military first asks for a simple tool. Then each command wants to add a mission. The drone must perform air-to-air combat, electronic warfare, intelligence gathering, data relay, decoy operations, strikes, and penetration. By piling on roles, we end up with a brilliant platform, but one too costly to be mass-produced.
The U.S. Air Force seems aware of the risk. It is working with multiple suppliers, mandating an open architecture, and promoting continuous competition. This is a sound approach. But it will need to resist its own technological temptation. The CCA must not become a perfect aircraft. It must become a useful, readily available aircraft produced on a large scale.
The Pacific demands a focus on volume and attrition
The CCA program is inextricably linked to China. The United States is preparing for the possibility of a conflict in the Indo-Pacific, particularly around Taiwan or the First Island Chain. In this theater, distances are considerable.
A mission from Guam to Taiwan represents several thousand kilometers round trip. U.S. bases would be vulnerable to Chinese missiles. Refueling aircraft would be essential, but also exposed.
In this context, every manned aircraft becomes valuable. Losing an F-35 or an F-47 would mean losing an expensive machine, a pilot trained for years, and a rare capability. UAVs allow for greater risk-taking. They can clear the way, absorb part of the enemy’s defenses, carry missiles, detect targets, or jam radars.
They can also complicate the enemy’s decision-making. A Chinese radar will have to distinguish manned aircraft from drones, decoys from armed platforms, and sensors from potential missiles. The denser the airspace, the more ammunition and attention the defense must expend. Mass then becomes a weapon in itself.
But this logic only works if there are many UCAVs. A fleet of a few dozen aircraft will be useful for experimentation. It will not change aerial warfare. A fleet of several hundred, supported by a robust industrial base, can shift the balance of power.
The program also sparks an industrial battle
UAVs are not just a military innovation. They are a test for the U.S. defense industry. General Atomics, Anduril, RTX Collins, Shield AI, and other players are vying for a place in an ecosystem that the U.S. Air Force wants to be more open. The Pentagon seeks to avoid industrial lock-in. It does not want a single supplier to control the airframe, autonomy, sensors, and software development.
This strategy can accelerate innovation. It can also create integration challenges. Operating multiple software systems, airframes, and mission standards in a combat environment requires very strict technical governance. Openness is useful only if it is disciplined. Otherwise, it creates complexity.
Production is the other critical issue. Building a few prototypes is one thing. Building 150 drones, and eventually several hundred, is another. It will require engines, materials, sensors, computers, test benches, technicians, maintenance lines, and inventory. The United States has rediscovered, through its experiences in Ukraine and the Middle East, that modern munitions can be consumed very quickly. UCAVs will teach the same lesson to the aerospace industry: without production, innovation remains merely a demonstration.
The next breakthrough will be as much doctrinal as it is technological
The success of UCAVs will not be measured solely by the first missile launch or the first autonomous flight. It will be measured by pilots’ ability to employ them without mental overload. We will need to train crews capable of commanding drones as teammates, without piloting them like remote-controlled aircraft. We will also need to define clear rules of engagement, procedures in case of loss of communication, levels of autonomous authority, and responsibilities in the event of an error.
The change will be cultural. For a century, combat aviation has placed the pilot at the center of the narrative. UCAVs shift that center to a hybrid team: pilot, drone, software, sensors, and network. The prestige may remain in the F-47’s cockpit. But part of the lethality will lie elsewhere, in machines without canopies, without ejection seats, and without human instinct.
This is what makes the program both promising and dangerous. Promising, because it can restore scale to a Western air force that has become too small. Dangerous, because it can create a dependency on complex, costly autonomous systems vulnerable to jamming. The U.S. gamble is clear: accept this complexity now to avoid facing Chinese scale later.
The F-47 may be the most visible aircraft of this revolution. But UCAVs could be its most decisive component. If the U.S. Air Force manages to keep costs under control, ensure reliable autonomy, and ramp up production quickly, it will profoundly change aerial warfare. If it fails, it will have merely added yet another expensive program to an already long list.
