You probably thought the age of the "old school" fighter was over. For a decade, the narrative was simple: if it isn't stealth, it’s a target. But walk onto the tarmac at Boeing’s St. Louis facility or visit the 142nd Wing in Portland, and you'll see something that defies that logic. The Boeing F-15EX Eagle II isn't just an old jet with a new coat of paint. It is a massive, twin-engine statement that raw power still has a place in a world of invisible planes.
Honestly, the F-15 should have retired years ago. The original C-models were literally falling apart, with some pilots restricted from pulling high G-loads because the airframes were tired. But then the Air Force realized something terrifying. The F-35, for all its "magic" stealth, can't carry enough weight to win a massive shooting war alone.
It needs a big brother.

The Eagle II is that brother. It’s the guy who stays in the back with a truckload of ammo while the stealthy guys go in and kick the door down.
What Actually Makes it an "Eagle II"?
If you look at an F-15EX and an old F-15C side-by-side, you might not notice the difference at first. Don't be fooled. Under the skin, this is a completely different animal.
Most people don't realize that the F-15EX is basically a "digital" jet. The old Eagles used a mess of pulleys and cables—mechanical connections that felt "heavy" to the pilot. The Eagle II uses fly-by-wire technology. Everything is electronic. This doesn't just make it easier to fly; it allows the computer to push the jet to its absolute aerodynamic limits without the pilot accidentally snapping a wing off.
Then there is the "brain."
Boeing packed in the Advanced Display Core Processor II (ADCP II), which is essentially the fastest mission computer in any fighter jet today. It can process 87 billion instructions per second. Why does that matter? Because modern war is just a competition of who can process data faster.
The Standoff Weapon "Magazine"
Here is the real kicker. An F-35 carries maybe four to six missiles internally if it wants to stay stealthy. The Boeing F-15EX Eagle II can carry up to 12 air-to-air missiles on its standard racks. If they use the new AMBER (Advanced Missile and Bomb Ejector Rack) systems, that number could theoretically jump toward 22.
That is an insane amount of firepower.

The Air Force's plan is simple: use the F-35 and F-22 as "quarterbacks." They sneak in, find the targets, and then "hand off" the targeting data to the F-15EX loitering miles away. The Eagle II then unleashes a barrage of missiles from a safe distance. It is a "missile truck" strategy that actually makes a ton of sense when you're facing hundreds of enemy drones or aircraft.
The Survivability Myth
"But it isn't stealthy!"
That’s the first thing everyone says. And they’re right. On a radar screen, the F-15EX looks like a flying barn door. But Boeing and BAE Systems have a workaround called EPAWSS.
The Eagle Passive Active Warning Survivability System is a mouthful, but it’s the jet’s secret weapon. It’s an all-digital electronic warfare suite that samples the entire electromagnetic spectrum. It doesn't just tell the pilot someone is looking at them; it can actively jam, spoof, and deceive enemy radars.
In some ways, being "loud" and having great jamming is better than being "quiet" and having no way to fight back once you're spotted. The EPAWSS system allows the Eagle II to operate in "contested" environments that would have been suicide for the older models.
Why 2026 is a Massive Year for the Eagle II
As of right now, in early 2026, the program is finally hitting its stride after some rocky years. You might remember the Boeing strike in late 2025—that 105-day standoff really gummed up the works. But the production line in St. Louis is back to humming.
Boeing is aiming to hit a delivery rate of two jets per month by the end of this year.
- Portland is the hub: The 142nd Wing of the Oregon Air National Guard was the first to get these birds. They’ve been proving that a pilot can transition from the old C-model to the EX in just a couple of weeks because the cockpits are similar enough.
- The Kadena Shift: This is the big news for 2026. The Air Force is moving 36 Eagle IIs to Kadena Air Base in Japan. Replacing the old Eagles in the Pacific is a massive priority because of the growing tensions in the region.
- The Cost Factor: Each F-15EX costs roughly $90 million to $97 million. That’s not cheap—honestly, it’s about the same price as an F-35. But the operating cost is where the Eagle wins. It uses the same hangars, the same tools, and many of the same parts as the thousands of F-15s already in service globally.
It’s About the "Outsized" Stuff
You can't fit a hypersonic missile inside an F-35. They are just too big.
The Boeing F-15EX Eagle II has a massive centerline pylon that can carry weapons up to 22 feet long and weighing 7,000 pounds. This makes it the primary candidate for the Air Force's future hypersonic programs, like the ARRW (Air-launched Rapid Response Weapon).

If we ever need to sink a carrier from 1,000 miles away, this is the jet that will carry the "big stick" to do it.
The Verdict on the Eagle II
Is it a replacement for stealth? No. It’s a partner.
The F-15EX is for the missions where you don't need to hide. It’s for homeland defense, where you need to intercept a stray aircraft at Mach 2.5. It’s for maritime patrol in the Pacific where you need to stay in the air for hours and carry a dozen harpoon missiles.
It is the ultimate "insurance policy" for the U.S. Air Force.
If you want to track the progress of the program, keep an eye on the deliveries to the 18th Wing at Kadena this spring. That deployment will be the real-world test of whether the Eagle II can actually handle the heat in a high-stakes environment. You should also watch for news regarding the "Collaborative Combat Aircraft" (CCA) program; the F-15EX is being prepped to act as a "mother ship" for swarms of loyal wingman drones, which would totally change how we think about aerial dogfighting.
Actionable Insights for Aviation Enthusiasts and Defense Analysts
- Monitor the Kadena Deployment: The arrival of the first 36 jets in Japan this spring will reveal how the Air Force intends to integrate the EX into its Pacific strategy.
- Watch the EPAWSS Upgrades: This system is being retrofitted into older F-15E Strike Eagles. Success there means the tech is mature and reliable.
- Track Production Rates: Boeing needs to hit that 2-per-month target by December 2026 to stay on budget. Any slip-up there could lead to further quantity cuts by Congress.
The Eagle II isn't a relic. It’s a 20,000-hour airframe designed to fight into the 2040s and beyond. Not bad for a jet people thought was "finished" twenty years ago.
