You’ve probably seen the headlines about grounded planes and "powder metal" flaws. If you follow the stock market, you know RTX (formerly Raytheon Technologies) has had a wild ride lately. But here’s the thing: most of the noise misses the actual story of what’s happening inside Pratt and Whitney right now. It is 2026, and the aerospace world is looking very different than it did even two years ago.
Honestly, the aviation industry has a short memory. People forget that Pratt and Whitney basically invented the modern jet age. They aren't just a "business unit" of RTX; they are the literal engine—pun intended—driving a $251 billion backlog.
The Powder Metal Crisis: Is It Finally Over?
Let’s address the elephant in the hangar. For a while there, the Geared Turbofan (GTF) engine was the industry’s problem child. A rare microscopic flaw in the powder metal used for turbine disks forced hundreds of Airbus A320neo jets to sit on the tarmac. It was a mess.
Fast forward to today, January 2026. The panic has cooled, but the work hasn't stopped. RTX is still shelling out about $1.2 billion annually in airline compensation, and inspection cycles are expected to stretch through the end of this year. But the "fix" isn't just a patch. It’s a complete overhaul of how they manufacture.
They’ve moved the goalposts.
Pratt and Whitney is currently rolling out the GTF Advantage. This isn't just some marketing rebrand. It’s a core redesign that increases takeoff thrust by up to 8% at high altitudes. More importantly, they’re claiming it will double the time these engines can stay on the wing before needing a shop visit. If you’re an airline like IndiGo or Spirit, that’s the difference between profit and a slow death by maintenance fees.
Why the F-35 Is the Real RTX Pratt and Whitney Powerhouse
While everyone was staring at commercial flight delays, the military side of the house was quietly winning. The F135 engine—the heart of the F-35 Lightning II—is effectively a monopoly. There is no "Choice B" for the most advanced fighter jet on the planet.
Just recently, in December 2025, the Pentagon handed Pratt and Whitney a $1.6 billion sustainment contract. That follows a massive $1.1 billion deal for F100 engine repairs. We’re talking about "generational" money.
The ECU Upgrade
The big talk in 2026 is the Engine Core Upgrade (ECU). The F-35 has a "power and cooling" problem—it’s packed with so much advanced electronics that the original engine is basically sweating to keep up. The ECU is the solution. It’s a mid-life boost that ensures the jet can handle the "Block 4" software updates without melting its internals.
Military analysts like Jill Albertelli have been vocal about this: if you don’t upgrade the engine, the world's most expensive jet becomes a very high-tech paperweight. Pratt won that fight against GE, who wanted to build an entirely new engine from scratch. The Pentagon chose the lower-risk, cheaper upgrade path, and RTX is laughing all the way to the bank.
Hybrid-Electric and the "Net Zero" Dream
Is green aviation a fairy tale? Kinda. But RTX isn't treating it like one.
They’ve been testing a hybrid-electric flight demonstrator on a De Havilland Dash 8. The goal is a 30% reduction in fuel burn. Think about that. A 30% jump in efficiency is unheard of in an industry that usually fights for 1% gains.
They are also betting big on Hydrogen Steam Injected, Inter-Cooled Turbine Engines (HySIITE). It sounds like something out of a sci-fi novel. Essentially, it uses liquid hydrogen's cold temperatures to boost efficiency while emitting zero CO2. It’s still in the "rig testing" phase, but they’ve already proven they can capture water from exhaust at a rate of one gallon every three seconds.
The 2026 Outlook: What’s Next?
If you’re looking for a takeaway, it’s this: the "crisis" years of 2023 and 2024 are in the rearview mirror. RTX has streamlined. They’ve paid down nearly $3 billion in debt recently. They are shifting from "fixing mistakes" to "building the future."

The supply chain is still a headache. Everyone knows it. You can't just order a turbine blade on Amazon. Pratt’s deliveries were lagging by an average of 238 days last year. They’re fixing this by bringing more "casting and forging" work in-house—investing $600 million to stop relying so much on outside vendors who can't keep up.
Actionable Insights for the Industry Watcher:
- Watch the A320neo selection: Keep an eye on whether airlines choose the GTF Advantage over the CFM LEAP. If Pratt regains market share there, the stock volatility will vanish.
- Monitor the F-35 Lot 18/19 contracts: These are expected to be finalized by Spring 2026. These numbers will dictate the military revenue floor for the next decade.
- Don't ignore the aftermarket: Pratt and Whitney makes the most money when engines are old and need parts. The current "shop visit" surge is actually a massive long-term revenue driver, even if the initial groundings were a PR nightmare.
The bottom line is that you can't have global travel or modern defense without RTX Pratt and Whitney. They are too big to fail and, as of right now, too advanced to replace.
To stay ahead of these developments, you should track the upcoming Q4 2025 earnings call scheduled for late January 2026, where the company will likely provide its most detailed guidance on free cash flow and production targets for the remainder of the year.
