You've probably seen the clickbait. Maybe you stumbled across a grainy, gray-scale thumbnail on YouTube or a frantic tweet claiming the Air Force just "unveiled" the F-47. It sounds sleek. It sounds futuristic. But if you’re looking for a spec sheet on the USAF sixth generation F-47 fighter, I have some bad news for you: it doesn't exist. Not yet, and maybe not ever under that specific name.
In the world of military aviation, names matter. We had the F-22 Raptor and the F-35 Lightning II. Naturally, people want to know what comes next. But the Pentagon isn't following a simple "add one to the number" logic anymore.
Right now, the United States is pouring billions into something called NGAD. That stands for Next Generation Air Dominance. It’s a "system of systems," not just a single plane. While some hobbyists and speculative illustrators have slapped the "F-47" label on their 3D renders, the Air Force hasn't actually assigned that designation to any airframe. Honestly, the obsession with the F-47 name is a classic example of how internet rumors outpace actual defense procurement.
Why the F-47 name is basically a myth
Military naming conventions are a bit of a mess, but they generally follow a pattern. After the F-22 and F-35, the next logical steps in the sequence were already mostly taken or skipped. We had the YF-23 (the Raptor’s rival) and the X-32 (the F-35’s rival). Some people jumped to F-47 because it sounds "advanced," but there is zero official documentation from the Department of the Air Force or companies like Lockheed Martin or Boeing using that tag.
If we look at the actual history of the "47" slot, it’s mostly empty in the modern fighter sequence. We had the P-47 Thunderbolt in World War II. It was a beast. A juggernaut of a plane. Maybe that’s why the rumor mill loves the F-47 moniker—it carries that historical weight. But in reality, the NGAD program is currently a classified competition.
Secretary of the Air Force Frank Kendall has been pretty vocal lately about the costs. He’s mentioned that a single manned fighter in this new generation could cost "hundreds of millions" of dollars. That’s triple the price of an F-35. When you’re spending that much, you aren't just building a "new F-22." You’re building a quarterback for a team of drones.

NGAD is the real USAF sixth generation fighter
Forget the F-47 for a second. Let's talk about what is actually happening in the hangars at Area 51 and the Skunk Works facilities. The Air Force is looking for a successor to the F-22, which is aging faster than most people realize. The Raptor is still the king of the skies, but its "skin" is a nightmare to maintain, and its computer architecture is basically a time capsule from the 90s.
The real sixth-generation effort is focused on five key technologies:
- Variable Cycle Engines: This is huge. Engines like GE’s XA100 can switch between high-thrust modes for combat and high-efficiency modes for long-range cruising. It’s like having a Prius and a Ferrari in the same engine bay.
- Digital Engineering: They aren't just sketching these on napkins. They are building "digital twins." They fly the plane millions of times in a simulator before a single piece of titanium is cut.
- The Loyal Wingman: This is where the F-47 rumors usually get mixed up. The manned fighter will be surrounded by CCA (Collaborative Combat Aircraft). These are high-performance drones that carry extra missiles or act as decoys.
- Advanced Stealth: We’re talking about "broadband" stealth. Current stealth is great against certain radar frequencies but vulnerable to others. The sixth-gen goal is to be invisible to almost everything.
- Open Architecture: You know how you can update your iPhone apps? The Air Force wants to be able to swap out the radar software or the electronic warfare suite on a Tuesday and have it ready for combat on Wednesday.
The program took a weird turn in mid-2024. Kendall announced a "pause" to look at the design. Why? Because drones are getting better so fast that the Air Force started wondering if they even needed a massive, expensive manned fighter at the center of the web. They’re re-evaluating the requirements to make sure they aren't building a dinosaur.
The China Factor
Why do we even need a USAF sixth generation F-47 fighter (or whatever it ends up being called)? Because China is moving incredibly fast. Their J-20 is a legitimate fifth-generation threat, and they are openly working on their own sixth-gen platform.
The Pacific is a big place. A really big place. If a conflict breaks out over Taiwan or the South China Sea, our current fighters don't have the "legs" to get there without a ton of tankers. And tankers are big, slow targets. The sixth-gen plane needs massive internal fuel tanks. It needs to be able to fly thousands of miles, fight, and come back without needing a mid-air refuel every 30 minutes.

This is why the design might end up looking less like a traditional fighter and more like a "flying wing" or a tailless delta. Tails are bad for stealth. If you can get rid of them and use "thrust vectoring" or fancy air-flow tech to turn, you become much harder to see on radar.
What's actually in the air right now?
In 2020, Will Roper, who was then the Air Force's tech chief, dropped a bombshell. He said a full-scale flight demonstrator for the next-gen program had already flown. It broke records.
People lost their minds. "Is it the F-47?" they asked.
Probably not. It was likely a "technology demonstrator"—a franken-plane used to test specific parts like the new engine or a specific wing shape. It’s a long way from a prototype to a production line. Think of it like a concept car at an auto show. It looks cool and it drives, but you can’t buy it at a dealership yet.
The Air Force is currently in a "quiet period" regarding the contract award. Lockheed Martin and Boeing are the likely finalists, especially since Northrop Grumman (the folks who make the B-21 Raider) bowed out of the lead contractor spot for the manned fighter portion.

The cost of dominance
Let’s be real: the price tag is terrifying.
If the F-35 program was a "trillion-dollar" headache, the NGAD program is going to be a wallet-breaker. We’re looking at $200 million to $300 million per plane. Some analysts think that’s optimistic. If the USAF only buys 200 of them, the unit cost skyrockets.
This is where the F-47 enthusiasts get it wrong. They imagine a swarm of thousands of these planes. In reality, we might only see a handful of the "manned" ships acting as command centers for hundreds of much cheaper drones. It’s a shift from "dogfighting" to "system management." The pilot isn't just a flyer; they are a battlefield commander sitting in a cockpit.
Actionable Insights for Defense Watchers
If you want to stay ahead of the curve on what the next generation of air power actually looks like, stop searching for "F-47" and start looking at the real indicators.
- Follow the CCA (Collaborative Combat Aircraft) contracts. Companies like Anduril and General Atomics are winning these. These drones will fly alongside the next fighter, and their development is moving much faster than the manned plane.
- Watch the B-21 Raider test flights. The tech being used on the new stealth bomber—the coatings, the sensors, the engines—is a direct cousin to what will be in the sixth-gen fighter.
- Monitor the engine tests. Keep an eye on the AETP (Adaptive Engine Transition Program). If the engine works, the plane follows. If the engine hits a snag, the whole program slides.
- Ignore the renders. Unless it comes from an official .mil source or a Lockheed/Boeing press kit, that sleek "F-47" image you saw on Instagram is just fan art.
The future of American air superiority isn't about a cool number like 47. It’s about whether we can integrate AI, stealth, and long-range sensors into a package that can survive a modern battlefield. The "F-47" might be a ghost, but the technology being built to replace the F-22 is very, very real. It's just going to look a lot different than the movies led us to believe.
To see where this is going, look at the recent budget requests for 2025 and 2026. The Air Force is shifting money away from old airframes to fund these "black programs." When the money moves, the metal eventually follows. We are currently in the "dark years" of the program where everything is classified, but the first official photos of the real sixth-gen prototype will likely leak or be "accidentally" shown in a recruitment video by 2027 or 2028. Keep your eyes on the Edwards Air Force Base flight lines. That’s where the truth usually lands.
