The US Air Force is accelerating Boeing’s F-47, a NGAD fighter engineered for stealth, supercruise, and CCA drones to counter China.
Summary
The F-47 is not a mere successor to the F-22 Raptor. It is the centerpiece of an aerial combat architecture designed for the Indo-Pacific, Chinese air defenses, and networked warfare. Selected in 2025, Boeing receives a strategic role with this program that Lockheed Martin seemed almost destined to retain. The US Air Force is committing very high budgets: approximately $3.45 billion in FY2026, over $5 billion in FY2027, and a projected peak around $5.25 billion in FY2028 for the F-47 and its associated technologies. The public objective is ambitious: a first flight around 2028, a combat radius exceeding 1,852 kilometers (1,000 nautical miles), speeds above Mach 2, advanced stealth, adaptive propulsion, and cooperation with more than 1,000 CCA drones. The reality is clear: the United States wants to preserve its air superiority before China frontally challenges it.
The F-47 program marks a strategic choice embraced by the US Air Force
In March 2025, the F-47 became the new face of American air superiority. The US Air Force awarded Boeing the engineering and manufacturing development contract for the Next Generation Air Dominance program, better known by the acronym NGAD. This choice surprised a portion of the sector. Lockheed Martin had designed the F-22 and the F-35. Northrop Grumman masters heavy stealth with the B-2 and B-21. Boeing, meanwhile, remained primarily associated with the F-15EX, the F/A-18E/F Super Hornet, and sometimes difficult programs like the KC-46.
The decision is therefore not only technical. It is industrial. It revitalizes Boeing Defense, Space & Security. It protects the St. Louis production line. It also avoids an excessive concentration of American air superiority in the hands of Lockheed Martin. In a future war, the US Air Force does not want to depend on a single industrial ecosystem.
The F-47 replaces the F-22 in the most demanding mission: entering contested airspace, surviving against modern radars, commanding a group of drones, detecting before being detected, and striking or intercepting at long range. This is not a classic multirole aircraft. This is a sixth-generation fighter jet, designed to gain the upper hand in the opening hours of a major conflict.
The budgetary message is sharp. The US Air Force is not reducing the F-47 to a technological showcase. It is funding it as a wartime priority.
The budget reveals an acceleration rather than mere posturing
The numbers show the true hierarchy of priorities. The F-47 program receives approximately $3.45 billion in FY2026. The request climbs to $5.04 billion in FY2027, then to $5.25 billion in FY2028. This curve indicates a heavy development phase, moving close to trials, initial test articles, and the integration of critical subsystems.
This level of investment is considerable. It far exceeds the funding of an isolated demonstrator. It indicates that the US Air Force wants to move fast, while accepting a high financial risk. Budget documents subsequently project a gradual decline toward $4.12 billion in FY2029, $3.29 billion in FY2030, and $2.95 billion in FY2031. This trajectory suggests that the most difficult expenditures are concentrated around 2027–2028, at the moment when the aircraft must enter a visible maturation phase.
Propulsion follows a similar logic. The NGAP program, for Next Generation Adaptive Propulsion, goes from approximately $326 million in FY2026 to $513.7 million in FY2027, then nearly $905.7 million in FY2028. This detail is paramount. The engine is not a secondary element. It dictates the operational radius, supercruise, electrical capacity, sensor cooling, and thermal survivability.
The US Air Force aims for more than 185 F-47s, with the possibility of going beyond. This figure corresponds to the order of magnitude of the F-22 fleet, whose production was halted too early. Washington does not want to repeat that mistake. The F-22 was exceptional but too rare. The F-47 must be more available, more sustainable, and easier to deploy.
F-47 technology responds primarily to the Pacific war
The requirements for the F-47 are not abstract. They respond to a specific theater: the Indo-Pacific. In this region, distances are immense. American bases are vulnerable. Tankers are targets. Chinese radars cover growing volumes. Long-range surface-to-air missiles, J-20 fighters, air-to-air missiles, and detection networks make the approach more dangerous than in the days of the F-22.
The announced combat radius, exceeding 1,852 kilometers (1,000 nautical miles), is therefore one of the most critical figures. The F-22 is generally credited with a combat radius around 1,093 kilometers (590 nautical miles). The F-35A sits around 1,241 kilometers (670 nautical miles). The F-47 must go further to reduce dependence on tankers, penetrate deeper, and remain useful across an immense airspace.
Speeds exceeding Mach 2 are not just a matter of prestige. They serve to dictate the place of combat. They allow for the rapid interception of a threat. They also improve the initial energy of air-to-air missiles fired from the aircraft. A missile launched at high speed and high altitude starts with a kinematic advantage. It can travel further, faster, and with more energy margin in its terminal phase.
The F-47 is therefore not envisioned for a romantic duel between fighters. It is engineered to kill from a distance, coordinate effectors, survive, and return.
Supercruise changes the way of entering combat
Supercruise refers to the ability to fly at supersonic speeds without afterburners. This is an essential difference. Afterburning provides high thrust, but it consumes large amounts of fuel. It also increases the infrared signature. In a modern environment, this can compromise the aircraft’s discretion.
A fighter capable of maintaining supersonic speed without afterburners can cover vast distances faster, conserve its fuel, and maintain a more controlled thermal signature. For the F-47, this quality is consistent with the Pacific theater. The aircraft must cross vast expanses, reach a combat point, launch missiles, and then reposition before the adversary locks in their response.
Supercruise also serves defense. A faster aircraft can exit a threatened zone more quickly. It can change axes. It can force the adversary to recalculate their firing geometry. In a war of missiles, speed is not a luxury. It is a margin of survival.
Advanced stealth targets modern radars, not radars of the past
The advanced stealth of the F-47 remains largely classified. But the logic is clear. The F-22 and F-35 were designed to reduce their radar signature, especially in certain frequency bands and certain angles. The F-47 must go further. It must confront radars that are more numerous, more mobile, more connected, and sometimes capable of cooperating with one another.
Modern stealth is not limited to the shape of the aircraft. It includes materials, air intakes, edge treatment, electromagnetic emission management, infrared discretion, low-probability-of-intercept data links, and the internal integration of weapons. Every detail counts. A poorly placed antenna, an open bay door, or an overly visible radio emission can reveal the aircraft.
The F-47 will therefore need to be stealthy, but also disciplined. It must see without emitting excessively. It must receive data, command drones, and maintain a low signature. This is more difficult than classic stealth. This is a networked stealth.
The F-47 is not an aircraft alone, but the leader of a system
The term NGAD is often misunderstood. It does not refer only to an aircraft. It refers to a family of systems. The F-47 is its manned center. Around it, the US Air Force wants to deploy Collaborative Combat Aircraft, or CCAs. These drones are often described as loyal wingmen. The expression is useful, but somewhat reductive. Their role will not only be to fly alongside a fighter. They will have to detect, jam, carry missiles, draw fire, extend radar coverage, penetrate dangerous zones, and sometimes be sacrificed.
American prototypes already carry official names. The YFQ-42A is developed by General Atomics. The YFQ-44A is developed by Anduril. Their designation is revealing: Y for prototype, F for fighter, Q for unmanned aircraft. For the first time, the US Air Force is giving a fighter designation to unmanned aircraft.
The announced target exceeds 1,000 CCAs. Their public combat radius is given as over 1,296 kilometers (700 nautical miles). The unit cost remains fluid, but initial estimates spoke of around $30 million per drone for the first increments, which is far less than a manned fighter. In FY2027, the US Air Force is requesting nearly $1 billion to begin purchasing CCAs.
The logic is brutal. An F-47 is too expensive to be exposed unnecessarily. A CCA can take more risks. It can fly ahead. It can carry missiles. It can serve as a decoy. It can force the enemy to reveal its radars. It can multiply mass without multiplying pilots.
This is the core of the concept: a small number of highly advanced manned aircraft, surrounded by a mass of semi-autonomous drones.
The adaptive engine will be one of the program’s arbiters
The propulsion of the F-47 is one of the most critical points. The NGAP program must deliver an engine capable of altering its configuration depending on the mission. An adaptive architecture can prioritize thrust in combat, fuel economy in transit, or cooling during a phase of heavy electronic load.
This cooling is an underappreciated topic. A sixth-generation aircraft carries powerful sensors, computers, data links, electronic warfare systems, and potentially, eventually, directed-energy weapons. All this equipment produces heat. In a stealth aircraft, one cannot simply vent this heat without consequences. The infrared signature becomes a tactical problem.
The adaptive engine therefore serves multiple objectives. It gives range. It supports speed. It provides energy. It helps manage heat. It makes a heavier, more connected mission architecture possible.
It is also a risk. New engines are expensive. They take time. They create industrial dependencies. If the NGAP slips, the F-47 slips. The US Air Force knows this. That is why propulsion budgets are rising alongside those of the fighter.
The F-47 positions itself above the F-35, not in its place
The F-47 does not replace the F-35. It primarily replaces the F-22 in the air superiority mission. The F-35 remains an aircraft for strike, intelligence, data fusion, and joint-force cooperation. The F-47 must be faster, longer-ranged, stealthier, and more specialized in first-entry and aerial dominance.
The difference is political and military. The F-35 is produced on a large scale and exported. The F-47 will be much more sensitive. Its technologies will likely remain highly controlled. It will not easily become an export aircraft. It will primarily be an American tool to retain a breakthrough capability in the most contested environments.
The F-15EX plays yet another role. It brings payload, range, and availability. It can carry many missiles, but it is not stealthy. It is useful behind a front line of stealth platforms. The F-47 opens, the F-35 connects and strikes, the F-15EX brings mass. The CCAs multiply the whole.
This positioning shows that the US Air Force does not believe in a single solution. It is building a tiered fleet.
American competition lost, but it remains influential
The choice of Boeing is a clear defeat for Lockheed Martin. The company had direct experience with the US Air Force’s most critical stealth fighters. It seemed naturally placed. Yet, Boeing won. This means its bid convinced on several counts: maturity, cost, architecture, industrial potential, or a combination of these factors.
Northrop Grumman withdrew from the competition as a prime contractor but remains a major player in stealth, sensors, and mission architectures. Its role as a supplier may remain significant.
Real competition therefore does not disappear. It shifts. Lockheed Martin continues to dominate the F-35 and is developing its own collaborative drone concepts. Northrop Grumman produces the B-21 Raider and works on autonomous systems. General Atomics and Anduril are disrupting historical industrial players in the CCA space. The F-47 opens a new phase: American air warfare will no longer be dominated solely by traditional large airframers. It will integrate more software, autonomy, drones, and companies originating from the technology world.
This is a cultural mutation as much as a change of platform.
The duel with China explains the American urgency
The F-47 targets China first. It would be hypocritical to claim otherwise. Russia remains a threat, but it does not dictate the requirements of the F-47 as much as the Indo-Pacific does. China combines stealth aircraft, anti-aircraft missiles, ballistic missiles, space-based sensors, drones, jammers, and an immense geographical depth.
Images appearing in late 2024 of new tailless Chinese aircraft heightened the pressure. Western experts noted two distinct designs, including a larger, diamond-shaped aircraft with an unusual air intake configuration. The actual performance is not known. Stealth, maneuverability, sensors, and engines remain impossible to judge from public images. But the signal is strong: China is experimenting seriously.
This is where the analysis must be frank. The United States likely retains the most comprehensive lead in systems integration, engines, sensors, operational experience, proven stealth, and networked warfare. But China is moving fast. It is no longer just imitating. It is testing original forms. It accepts risk. It puts pressure on the American timeline.
The F-47 is therefore less a response to the J-20 than a response to the next Chinese aerial system.
GCAP is advancing more cleanly than the European FCAS
Faced with the F-47, Europe is divided. The GCAP program, led by the United Kingdom, Italy, and Japan, appears better structured today. Its official objective remains an entry into service in 2035. It relies on BAE Systems, Leonardo, Mitsubishi Heavy Industries, and the Edgewing joint venture. Italy approved 8.77 billion euros in funding in 2026 for the initial phases, with early costs now estimated at 18.6 billion euros.
GCAP also aims for a connected architecture, featuring manned and unmanned platforms, advanced sensors, and a combat cloud. It is coherent. It is moving forward. But its timeline remains more distant than that of the F-47.
FCAS is more fragile. The French-German-Spanish program carries a comparable ambition: a next-generation fighter, drones, a combat cloud, sensors, and connected armaments. However, industrial tensions between Dassault Aviation and Airbus run deep. The sticking point is clear: who commands the fighter? Dassault wants clear prime contractorship. Airbus, representing mainly Germany and Spain, wants a more balanced distribution. This political architecture slows down technical decision-making.
FCAS may survive in a partial form, notably regarding drones and the combat cloud. But its fighter pillar is uncertain. This is a strategic problem for continental Europe. While the Americans fund the F-47 with billions, Europe is still debating industrial governance.
The United States has more of a systemic lead, but not a monopoly on innovation
The answer to the question of advancements is nuanced. The United States appears ahead on the complete architecture: manned aircraft, adaptive engine, CCA drones, massive budget, prototypes accumulating flight hours, a first flight schedule around 2028, and an already envisioned doctrine of employment.
China might be ahead regarding the public visibility of demonstrators. Its new aircraft have been seen in flight. But this does not prove operational maturity. A prototype that flies is not enough. You need a reliable engine, sensors, weapons, software, maintenance, trained pilots, data links, a doctrine, and production.
GCAP appears solid but slower. FCAS remains technologically ambitious but politically hampered. Australia is moving forward with the MQ-28A Ghost Bat, showing that collaborative drones are not an exclusively American domain. But the American scale remains superior.
The true advantage of the United States therefore lies in the combination: money, experience, industrial bases, secret trials, engines, software, drones, doctrine, and the ability to make a decision. This is the combination that others struggle to reproduce.
The F-47 bet remains risky despite its ambition
The F-47 could become the most important aircraft for the US Air Force since the F-22. It could also become an expensive, complex program vulnerable to delays. The risks are obvious. Boeing must prove it can execute a top-tier stealth program after difficult years across several military contracts. The NGAP engine must deliver on its promises. The CCAs must become autonomous enough to be useful without creating uncontrollable legal, tactical, or political risks.
Cost remains the other threat. An aircraft announced as cheaper than the F-22 can nevertheless become too expensive if requirements multiply. The sixth generation can easily fall into the trap of over-complexity. The more the aircraft tries to do everything, the more fragile it becomes budgetarily.
But the US Air Force does not have many alternatives. Modernizing the F-22 is not enough. Buying more F-35s does not solve the problem of very long-range air superiority. Relying solely on drones would be premature. CCAs need a flight leader, a decision node, and a survivable platform.
This is the role the F-47 must fill.
The new age of air superiority begins with a rupture
The F-47 is not just a faster, longer-ranged stealth aircraft. It is proof that the US Air Force accepts a profound rupture. The pilot will no longer be alone at the center of combat. They will command a pack of systems. Speed will serve range. Stealth will serve the network. The engine will serve electronic power as much as thrust. The drone will no longer be an accessory. It will become a component of firepower.
This shift does not guarantee an American victory. China is progressing rapidly. Europe retains major capabilities. Costs can overrun. Deadlines can slide. But the F-47 shows that Washington does not want to endure the next aerial revolution. It wants to impose it.
The air superiority of the future will no longer be played out merely between two aircraft. It will be played out between two industrial systems, two sensor networks, two decision chains, and two capabilities to produce intelligent mass. In this competition, the F-47 is the most ambitious American bet. It is also the most revealing: the fighter aircraft of the future will only be powerful if it knows how to command what flies around it.
