Megaprojects (AKA Simon Whistler) takes a look at the forthcoming, radically advanced F-47 stealth fighter.
“The F-47 is the United States Air Force’s new sixth generation air superiority fighter.”
“It’s being built by Boeing as the centerpiece of the Next Generation Air Dominance program, or NGAD. Because the military loves a good acronym almost as much as they love overspending.”
“It is designed to be the successor to the F-22 Raptor, which means its primary job is simple: Go to a place where the enemy has absolute control of the air, kill everything flying, and then come home safely.”
“It’s built to operate as the quarterback of a swarm of semi-autonomous drones fighting in environments that are far too dangerous for today’s aircraft.”
“Why F-47? Well, it turns out the designation is a piece of triple layered symbolism. Historically, the F-47 designation was used in 1947 for the legendary P47 Thunderbolt, the unkillable heavy fighter of World War II. It also conveniently nods to 1947, the year the US Air Force was founded as an independent branch. And perhaps most importantly for the people signing the checks, it lines up oh so perfectly with the 47th president who pushed the program over the finish line.”
The F-22 was designed for the Cold War, but the Cold War ended.
“The threat shifted to the vast empty expanse of the Pacific. And in the Pacific, the Raptors got a bit of a problem. In military speak, it’s called combat radius. Basically how far the jet can go, do its job, and then get back home without running out of fuel. The F-22’s got a combat radius of about 590 nautical miles. The F-35 is a little bit better at around 670. That sounds like a lot until you look at a map of the Pacific Ocean, which is really big. In that theater, 600 mi gets you from your air base to, well, the absolute middle of nowhere.”
“The requirement for this new jet is a combat radius of over 1,000 nautical miles.” That’s a 70% increase over the F-22. “It means this jet can take off from London, fly a combat mission over Moscow, and fly back to London without needing to refuel.”
“The F-47 isn’t just a super fighter designed to go out and dogfight alone. It’s that quarterback we mentioned of a family of systems. It’s designed to fly into battle surrounded by loyal wingman drones, sensors, and electronic warfare platforms.”
“Internal estimates from the Air Force have put the price of a single F-47 around $300 million. For context, that’s roughly three times the price of an F-35. It is a staggering amount of money.”
“By the time President Trump announced the F-47 name, there hadn’t just been one prototype. There had been multiple X-planes flying hundreds of hours in secret test ranges.”
Boeing beat out competing finalist Lockheed Martin for the contract.
“But in 2024, the whole program almost drove off a cliff. Air Force Secretary Frank Kendall looked at that $300 million per jet price tag and hit the pause button. The service spent months frantically studying alternatives. Could they just buy more F-35s? Could they upgrade older F-15s? By early 2025, the answer came back. No, that’s not going to be enough. If they want to beat China in the 2030s, they need this plane.”
“The timeline here is super aggressive. The Air Force claims that the real F-47, not just the demonstrators, will take its first flight around 2028. The goal is to have the first operational units ready by early 2029.”
Top speed is over Mach 2, and it’s capable of supercruise (i.e., fly over Mach 1 without afterburners for fuel efficiency).
The planned buy is 185 units, roughly the size of the current F-22 fleet. “This tells us the Air Force isn’t planning to replace every F-16 with an F-47. This is a plane that is going to be reserved for the absolute hardest missions”
“And finally, there’s the most controversial spec of all, its stealth rating. On the official Air Force graphic, the F-35 is labeled as stealth. The F-22 is labeled as stealth+. The F-47 is labeled as stealth++.”
“The F-47’s shape suggests that it’s designed to be invisible to everything.” Including low-frequency radar.
“Every official rendering shows a blended wing body, a shovel-nosed diamond-shaped wedge with no tail fins. This is the holy grail of stealth.”
“Without computers making micro adjustments a thousand times a second, a tailless fighter is just going to flip over and have a bad time.”
“The new adaptive engines, likely either GA’s XA102 or Prattt & Whitney’s XA103, can literally change their internals in mid-flight. They use a third stream of air flow to switch between a fuel sipping cruise mode and a high thrust combat mode. It gives you 30% more range and 20% more thrust from the same tank of gas.” Sort of like how the SR-71 engine switched internal configurations during different phases of flight.
“The F-47 is built with a modular open systems [computer] architecture…The hardware is just a shell for software that could be constantly updated. If a new missile or sensor is invented in 2035, well, you can just plug it in.”
Some speculate it could carry nuclear weapons if need be.
“But the most radical part of the F-47 isn’t the plane itself. It’s its mates. The F-47 is designed to never fight alone. It is the leader of a pack of robotic wingmen called collaborative combat aircraft, or CCAs. These are semi-autonomous drones that fly alongside the manned fighter. They’re jet powered, stealthy, and crucially, they’re affordable. The Air Force is targeting a price of $25 to $30 million per drone, which does sound like a lot, but compared to the $300 million mothership, these things are practically disposable. In March 2025, the Air Force designated the first two demonstrators for this program: The YFQ42A from General Atomics and the YFQ44A from Anduril.”
“The pilot in the F-47 is not flying them with a joystick. They’re just giving them commands like a quarterback calling a play. Drone One, jam that radar. Drone Two, fly ahead and scout. Drone Three, shoot anything that moves. The onboard AI is going to do the rest, which is pretty cool. This completely changes the job of the pilot. You’re no longer just an ace looking through a HUD. You’re essentially a sort of distributed air battle manager commanding a small robot squadron from the cockpit.”
“You can use the drones as missile trucks carrying extra weapons so the F-47 doesn’t have to ruin its stealth. You can send them ahead as decoys to trigger enemy defenses. You can even have them sacrifice themselves to save the manned jet. Like we said, they’re disposable $30 million drones.”
The Boeing contract for the F-47 is structured differently than Lockheed Martin’s was for the F-35, which was a walled garden. “If the Air Force wants to upgrade the F-35, they’ve got to go and pay Lockheed to do it, which is fantastic for Lockheed, but not so much for the Air Force. Secretary of the Air Force Frank Kendall has publicly called that arrangement a quote serious mistake. For the F-47, the government is demanding government purpose rights for all that data.” It’s going to be a much more plug-and-play option, allowing different defense contractors to upgrade different components.
Unlike the F-22, Boeing might be allowed to sell slightly less capable versions of the F-47 to allies.
Snipping the section on potential rivals, like China, since right now it’s vaporware, and China’s capabilities always seem to radically lag their outsized boasts.
“The level of technical risk here is honestly pretty terrifying. The Air Force is trying to develop a new stealth airframe, a revolutionary adaptive cycle engine, a brand new mission system architecture, and a fleet of autonomous AI drones all at the same time. And they are trying to do it on a schedule that is significantly faster than the F-35s.” All true. But we’re radically far ahead of anyone else.
“Many aviation analysts, including those at the Warzone, have described the F-47 as likely being the Air Force’s last manned tactical jet.”
“There’s a human in the cockpit, but they’re not really there to pull Gs and dog fight. They’re there to make moral decisions and manage the swarm. It’s less Maverick and more systems administrator in a G-suit.”
“The pilots training today might be the last generation to ever actually sit inside the weapon that they are flying. After the F-47, the human likely moves to a ground control station and the cockpit becomes empty forever.”
Very possibly. Technology improves by leaps and bounds, while humans remain human. Plus an unmanned aircraft can pull radically more Gs than a manned one can…
