If you’re driving through the quiet, wooded backroads of York County, you don't exactly expect to stumble upon a facility that builds the guts of the world’s most advanced fighter jets. But there it is. Pratt & Whitney North Berwick Maine is, quite literally, a behemoth hiding in the pines. Spanning over one million square feet, it is the largest manufacturing plant under a single roof in the entire state of Maine.
Honestly, the scale is hard to wrap your head around until you see the parking lot. Thousands of Mainers cycle through those doors every day, working on tech that most of us only see in Top Gun sequels or at 35,000 feet on the way to a vacation. It’s a place where high-stakes engineering meets the legendary Maine work ethic.
What Actually Happens Inside the North Berwick Plant?
Most people think of "Pratt & Whitney" and imagine the giant engines hanging off the wings of a Boeing 737. While that’s true, the North Berwick site—formally known as North Berwick Aero Systems (NBAS)—is more like the high-tech kitchen where the most difficult "ingredients" are made.
They don't just "make engines" here. They manufacture approximately 850 different part numbers and assemble around 30 different engine sub-assemblies. Basically, they specialize in the rotating parts and complex modules that have to survive extreme heat and pressure without failing. If a part in a jet engine fails, it’s a bad day for everyone. In North Berwick, "good enough" doesn't exist.
The Military Muscle: F135 and Beyond
A huge chunk of the work in North Berwick is dedicated to national defense. They are a primary site for the F135 engine, which powers all three variants of the F-35 Lightning II.
- F-35A: Conventional takeoff.
- F-35B: The one that can hover and land vertically (STOVL).
- F-35C: The carrier version with the tailhook.
Senator Susan Collins recently toured the floor, noting that the work here is "critical to our national security." It’s not just political talk. With the U.S. and its allies ramping up F-35 production into 2026, the North Berwick facility is under constant pressure to deliver. They recently secured a massive $1.6 billion contract for F135 sustainment, meaning this plant isn't just building new stuff—it’s the lifeblood that keeps the current fleet in the air.

The 2026 Shift: GTF Advantage and New Tech
If you've followed aerospace news lately, you've probably heard about the "GTF" (Geared Turbofan) engines. These are the fuel-efficient engines used on planes like the Airbus A320neo. They had some growing pains a couple of years ago involving powder metal issues, but 2026 is the year of the comeback.
Pratt & Whitney is currently rolling out the GTF Advantage. This version is designed to be even more durable, with first production engines hitting the skies right about now. North Berwick is deeply involved in producing the components that make this engine 90-95% more durable in harsh environments compared to earlier versions.
They aren't just stuck in the present, either. The facility is a testing ground for:
- Rotating Detonation Engines: A wild new way to burn fuel that could revolutionize speed.
- Hybrid-Electric Propulsion: Trying to make flying "greener" without losing power.
- Advanced Coatings: Using thermal plasma spray to protect parts from melting.
Working at Pratt & Whitney North Berwick Maine
You’d think you need a PhD in rocket science to get through the door, but that's a common misconception. While they have hundreds of engineers, a huge portion of the 2,300+ employees are skilled technicians and operators.
Kinda cool fact: they actually want to train people from scratch. In early 2026, they've been posting roles for "Manufacturing Operators" where you don't even need machining experience. They put you through a three-week training program and then a couple of months of on-the-job mentoring.

The Perks Are Real:
- The Weekend Shift: Work three 12-hour shifts (Friday-Sunday) and get paid for 40 hours.
- The Scholar Program: They will literally pay for your college degree or certifications from day one. No waiting period.
- The Pay: In a state where wages can be hit-or-miss, P&W is known for being one of the most stable, high-paying employers in Southern Maine.
Why This Place Matters to Maine’s Economy
Maine isn't just about lobsters and L.L. Bean boots. Aerospace is a quiet pillar of the state's economy, and Pratt & Whitney is the anchor.
Think about the ripple effect. When 2,300 people have high-paying jobs in a town of 5,000, it supports every pizza shop, hardware store, and car dealership in the region. They also fuel a massive supply chain. There are dozens of smaller machine shops across Maine and New Hampshire that exist solely to provide specialized bits and pieces to the North Berwick plant.
Common Questions (And the Real Answers)
Is the plant still expanding? Yes. They’ve invested hundreds of millions into their global footprint, and North Berwick stays updated with the latest "Industry 4.0" tech—basically robots and smart sensors that track every single cut a machine makes.
Do you have to be a US citizen? For most roles, yes. Because they work on the F-35 and other "black box" military tech, ITAR (International Traffic in Arms Regulations) rules are strictly enforced.

Is it a "clean" factory? It's surprisingly clinical. It’s not the greasy, dark machine shop of the 1950s. It’s bright, temperature-controlled (to keep the metal from expanding or contracting during precise cuts), and filled with computer screens.
