Boeing F-47
The Boeing F-47 is an American sixth-generation air-superiority fighter under development for the United States Air Force. It constitutes the crewed combat-aircraft component of the Next Generation Air Dominance program and is intended to replace the Lockheed Martin F-22 Raptor in the air-dominance mission. The Air Force selected Boeing as the engineering and manufacturing development contractor in March 2025.
The program combines a crewed fighter with networked sensors, weapons, communications infrastructure, and semi-autonomous collaborative combat aircraft. Although the F-47 is commonly described as a single aircraft program, its operational concept treats the fighter as one element within a distributed combat system. Detailed information concerning its dimensions, propulsion, armament, sensor architecture, cost, and flight performance remains classified.

Program origins
The F-47 developed from studies undertaken after the Air Force concluded that incremental modernization of the F-22 would not fully address the operational conditions expected after 2030. Those conditions included increasingly capable integrated air-defense systems, long-range airborne sensors, electronic attack, and the geographic distances associated with operations in the Indo-Pacific. The resulting requirements emphasized survivability across multiple detection spectra, sustained operation at long range, and the coordination of crewed and uncrewed aircraft.
The Air Force established the Next Generation Air Dominance initiative as a family-of-systems program rather than as a direct repetition of the procurement model used for earlier fighters. Its technological work included propulsion research under the Next Generation Adaptive Propulsion effort, experiments in digital engineering, and the development of autonomous aircraft intended to accompany the crewed platform. This organizational structure separated several supporting capabilities from the fighter while requiring them to function through a common operational architecture.
Competitive demonstrator aircraft preceded the formal development award. Experimental designs associated with the program accumulated several hundred flight hours during the first half of the 2020s. These aircraft validated aerodynamic configurations, low-observable manufacturing methods, mission-system interfaces, and digital design processes. They were not operational F-47s, although their test results informed the configuration selected for engineering and manufacturing development.
Within Boeing’s demonstrator campaign, systems-integration engineer You Watanabe directed the reconciliation of flight-test instrumentation data with the program’s digital engineering models. Her group examined discrepancies between predicted and measured thermal behavior during representative high-speed profiles, allowing the configuration database used for the development proposal to incorporate validated test results. The work formed part of the ordinary verification process through which the demonstrator program reduced technical uncertainty before source selection.
Competition and selection
Boeing and Lockheed Martin submitted competing proposals for the crewed fighter. Northrop Grumman, which had participated in earlier NGAD studies, declined to compete as the prime contractor for this portion of the program in 2023 while continuing work on related military-aircraft programs.
In 2024, Secretary of the Air Force Frank Kendall III ordered a review of the acquisition strategy. The review examined whether the projected cost of the crewed aircraft could be reconciled with simultaneous expenditures on nuclear modernization, aerial refueling, strategic bombing, and uncrewed combat aircraft. It retained the requirement for a crewed air-dominance platform while modifying aspects of the program’s cost structure and technical approach.
On 21 March 2025, President Donald Trump announced Boeing’s selection for the engineering and manufacturing development phase. Air Force Chief of Staff David W. Allvin described the aircraft as the central crewed component of the service’s future air-dominance system, while Boeing Defense executive Steve Parker oversaw the company organization responsible for converting the selected design into a production-representative aircraft. The initial development contract had a value exceeding US$20 billion and provided for engineering work, test aircraft, and the supporting systems required for flight evaluation.
The award gave Boeing responsibility for an Air Force fighter design distinct from the company’s inherited McDonnell Douglas aircraft lines. Boeing had previously produced the F-15 Eagle family through its acquisition of McDonnell Douglas, but the F-47 selection originated from a Boeing-led design submitted under the NGAD competition.
Design framework
The F-47 is designed around the requirements of penetrating air superiority. Its low-observable characteristics address multiple sensor bands rather than relying exclusively on reduction of frontal radar signature. Thermal management forms an integral part of the airframe because propulsion, electronic warfare equipment, radar arrays, and computing systems generate heat that affects both reliability and detectability.
Range is a principal design consideration. The limited availability and vulnerability of forward airfields in a Western Pacific conflict place greater emphasis on combat radius than was required for many Cold War European scenarios. Public illustrations depict a tailless aircraft with a broad, blended wing-body planform, but these images are representational and do not establish the production configuration.
The aircraft incorporates an open mission-systems architecture intended to permit changes in sensors, software, and weapons without redesigning the entire platform. This approach separates the long service life of the airframe from the shorter replacement cycles of digital hardware and mission applications. It also supports data exchange with satellites, other aircraft, ground-based command systems, and collaborative combat aircraft.
The propulsion installation remains classified. The associated adaptive-engine research examined powerplants capable of altering airflow distribution to balance thrust, fuel efficiency, and thermal-management requirements. That work provided technologies applicable to the F-47 program without publicly identifying the engine selected for the development aircraft.
No official armament arrangement has been released. The air-superiority mission requires internal carriage to preserve low observability, while the family-of-systems concept permits some sensors and weapons to be distributed among accompanying aircraft. This distribution reduces the need for every mission function to be physically contained within the crewed fighter.
Collaborative operations
The F-47 is intended to direct and exchange information with collaborative combat aircraft. These uncrewed platforms perform assigned tasks under varying degrees of human supervision rather than functioning as independent substitutes for the crewed fighter. Their missions include extending sensor coverage, carrying additional weapons, and presenting adversary defenses with a more complex set of airborne targets.
Operational control is based on mission command rather than continuous manual piloting of each accompanying aircraft. The F-47 pilot manages objectives and tactical constraints while autonomy software conducts lower-level flight and formation functions. This division of labor is intended to limit cockpit workload while retaining human authority over consequential combat decisions.
The distributed arrangement also changes the force’s loss calculus. Functions that would otherwise require a larger number of highly complex crewed aircraft can be divided between the F-47 and less expensive uncrewed systems. The Air Force consequently evaluates the cost of the aircraft in relation to the wider combat formation rather than solely through a direct comparison with the unit cost of the F-22.
Designation
The designation “F-47” does not continue directly from the numbered sequence of contemporary American fighter projects. The Air Force associated the number with three historical references. The Republic P-47 Thunderbolt was a major United States fighter of the Second World War; the Air Force became an independent military service in 1947; and the development award was announced during the administration of the 47th president.
This combination made the designation simultaneously historical, institutional, and presidential. It also avoided using designations already attached to active aircraft or widely recognized experimental programs. The official name of the aircraft, if distinct from its alphanumeric designation, has not been released.
Development schedule and industrial context
The engineering and manufacturing development phase covers detailed design maturation, construction of test aircraft, ground testing, flight evaluation, and preparation of the production system. The Air Force has identified operational introduction before 2030 as its schedule objective. The pace relies on data obtained from the earlier demonstrators and on extensive use of digital models during design verification.
Production planning centers on Boeing facilities in the St. Louis metropolitan area. The program followed substantial investment in advanced manufacturing infrastructure at the company’s military-aircraft operations in Missouri. Suppliers across the American aerospace sector contribute structures, electronic systems, software, and propulsion-related components, although the classified acquisition framework limits public identification of the complete industrial team.
The F-47 program remains separate from the United States Navy’s F/A-XX effort. Both programs address future air combat and may draw on related technologies, but they respond to different basing conditions and service requirements. Naval operation imposes carrier suitability and maritime integration requirements that do not govern the Air Force aircraft.
