On March 21, 2025, the United States formally acknowledged the existence of a new combat aircraft program that has remained largely hidden for more than a decade. Designated the F-47, the aircraft is described as the world’s first sixth-generation air superiority fighter. While the public reveal was limited to a small scale model and brief official statements, the actual aircraft remains concealed at undisclosed test facilities, likely within highly secured sites in Nevada or Missouri.

Almost every detail surrounding the F-47 is classified. What is known comes from limited official disclosures, defense budget documents, congressional testimony, and intelligence assessments. Together, these fragments outline an aircraft intended to replace the F-22 Raptor and serve as the central pillar of the U.S. Air Force’s Next Generation Air Dominance (NGAD) program.

A Strategic Replacement for the F-22

The F-47 is designed to assume the role of America’s primary air superiority fighter. Its mission profile is clear: penetrate heavily defended airspace, defeat advanced enemy aircraft and air defenses, and operate deep inside contested regions while remaining survivable.

Unlike previous fighters, the F-47 is not built to operate alone. It is designed as a command platform for semi-autonomous systems, coordinating drones, sensors, and electronic warfare assets in combat zones considered too dangerous for conventional aircraft.

The name “F-47” carries layered symbolism. It references the historic P-47 Thunderbolt of World War II, acknowledges 1947—the year the U.S. Air Force became an independent service—and aligns with the 47th presidency, during which the program received final approval.

The push for a new aircraft is driven by changes in the global security environment. The F-22, once unmatched, was designed for Cold War-era conflicts over Europe. Modern strategic realities are different, particularly in the Indo-Pacific.

A key limitation of existing fighters is combat radius. The F-22’s range, roughly 590 nautical miles, and the F-35’s approximate 670 nautical miles, are insufficient for operations across the Pacific without heavy reliance on aerial refuelling. Refuelling aircraft, however, are highly vulnerable in modern missile-saturated environments.

The F-47 is intended to solve this problem. Its required combat radius exceeds 1,000 nautical miles, allowing it to operate from distant bases while keeping vulnerable support aircraft out of enemy missile range.

At the same time, potential adversaries have advanced significantly. China fields the J-20 stealth fighter in large numbers and is reportedly testing next-generation, tailless aircraft prototypes. Integrated air defence systems have also become more sophisticated, combining layered radar networks and long-range missiles. Survival in this environment requires not just speed and stealth, but overwhelming situational awareness and networked combat capability.

Origins of the Program

The F-47 program traces its roots to research initiated around 2014 under the Defense Advanced Research Projects Agency (DARPA). Early efforts focused on “penetrating counter-air” concepts—aircraft capable of operating deep within the most heavily defended airspace on Earth.

These efforts evolved into the NGAD program, which remained largely opaque for years. In September 2020, the Air Force revealed that a full-scale NGAD demonstrator had already flown and achieved undisclosed performance milestones. By 2025, multiple experimental aircraft were reportedly logging flight hours at classified test ranges.

The development competition initially involved Lockheed Martin, Boeing, and Northrop Grumman. Northrop exited the race in 2023, leaving Boeing and Lockheed Martin as the final contenders. In 2025, Boeing was awarded the contract, marking a critical win for its defense division.

Cost and Procurement Challenges

Internal estimates place the cost of each F-47 at approximately $300 million, making it one of the most expensive combat aircraft ever conceived. The Air Force maintains that advanced digital engineering and manufacturing techniques will ultimately reduce costs, potentially bringing the aircraft below the inflation-adjusted price of the F-22.

The planned procurement target is 185 or more aircraft, roughly matching the size of the current F-22 fleet. This limited number underscores the aircraft’s intended role: reserved for the most demanding missions rather than broad deployment.

However, cost remains a central risk. The F-22 program itself suffered from shrinking production numbers, driving up unit costs and limiting operational use. Defense analysts warn that a similar “death spiral” could affect the F-47 if budgets tighten or procurement numbers are reduced.

What Is Known About the Design of F-47

Although no official specifications have been released, several characteristics are widely assessed:

• Range: Over 1,000 nautical miles combat radius
• Speed: Greater than Mach 2, with sustained supersonic cruise
• Stealth: Labeled “Stealth++” in Air Force graphics, implying broadband stealth across multiple radar frequencies
• Airframe: Tailless, blended wing-body design optimized for low observability
• Production Size: Approximately 185 aircraft

The aircraft is expected to be powered by next-generation adaptive cycle engines, capable of altering airflow configurations in flight to balance fuel efficiency and high thrust. These engines promise increased range, greater power, and improved thermal management for advanced sensors and weapons.

The F-47 is also built around a modular open systems architecture, allowing sensors, software, and weapons to be upgraded throughout its service life without dependence on a single contractor.

A Drone-Centered Combat Model

One of the most significant aspects of the F-47 is its integration with Collaborative Combat Aircraft (CCAs)—semi-autonomous drones designed to operate alongside the fighter. These drones are expected to perform reconnaissance, electronic warfare, missile carriage, and decoy roles.

The Air Force plans to acquire hundreds, potentially thousands, of CCAs to support the NGAD fleet. Two early demonstrators, the YFQ-42A and YFQ-44A, are already under development. These systems shift the role of the pilot from direct combat maneuvering to battlefield management, coordinating multiple assets simultaneously.

Global Competition

The F-47 emerges amid a global race for sixth-generation airpower. China is widely believed to be testing advanced stealth aircraft concepts, while the United Kingdom, Japan, and Italy are pursuing the Global Combat Air Programme (GCAP). France, Germany, and Spain are developing a parallel system under the Future Combat Air System (FCAS) initiative.

All of these efforts share common design traits—large, stealth-optimized airframes capable of commanding drone formations—reflecting converging solutions to the same technological and strategic challenges.

Risks and Strategic Implications

The F-47 program carries significant technical, financial, and strategic risk. It combines new airframe designs, revolutionary propulsion, advanced autonomy, and compressed development timelines. Any major delay or cost overrun could jeopardize production goals.

Beyond engineering concerns, analysts increasingly view the F-47 as potentially the last manned U.S. air superiority fighter. Its operational concept positions the human pilot as a decision-maker overseeing autonomous systems rather than a traditional dogfighter. Future platforms may remove the cockpit entirely.

Secrecy remains both a strength and a vulnerability. Limited transparency complicates oversight but also forces adversaries to plan against worst-case capabilities that remain unseen.

What Remains Unknown

Despite official confirmation of the program, critical questions remain unanswered:

• The aircraft’s exact configuration and dimensions
• Which adaptive engine design will be selected
• The true extent of its stealth capabilities
• Whether procurement targets can be met within budget

If the F-47 performs as intended, it could secure U.S. air dominance well into the mid-21st century. If it fails, it risks becoming an ultra-expensive, limited-use asset.

For now, the F-47 exists largely in secrecy—an aircraft designed to be unseen, shaping the future of air combat long before it ever appears in public view.
