Pratt & Whitney Rzeszów Engine Parts Facility Expansion, Rzeszów, Poland

Jet engine output is limited by a few parts, and Pratt & Whitney is putting $100 million into one of them. On Oct. 23, 2026, the RTX business broke ground on a 6,500-square-meter (about 70,000-square-foot) facility at its Rzeszów campus in southeastern Poland. The building will process isothermally forged rotating parts, the compressor and turbine disks that have been a choke point for engine deliveries.

The company priced the project at 375 million zloty. It expects the plant to be operating in 2028 with more than 120 new jobs.

Project Scope

The new building sits within Pratt & Whitney’s existing Rzeszów site on Hetmańska Street, one of the company’s largest outside North America. When the company first announced the investment in April, it said the facility would house heat treatment, sonic machining and inspection for isothermally forged parts. That’s a step up from what Rzeszów does today. The site already makes the GTF fan drive gear system, F100 static structures and F135 components, and it builds whole engines for helicopters, business jets and general aviation in the PT6, PW200, PW500/600 and PW800 families.

The Polish plant is half of a paired investment. In February, Pratt & Whitney committed $200 million to a seventh isothermal forging press at its Columbus Forge in Georgia. The press makes the raw forgings and Rzeszów will finish them. The company says the two projects, both due in 2028, should lift output of critical rotating parts by about 30%.

RTX hasn’t named a designer or general contractor for the Rzeszów building, and it hasn’t released a floor-by-floor program. Heat-treat furnaces and precision machining lines usually drive the structural and utility design for this kind of plant, with heavy slab loads, high power draw and tight temperature control for inspection rooms.

Why It Matters

Airlines have spent three years waiting on engines, and a big part of the delay traces back to forgings and the finishing steps that come after them. Adding a press in Georgia doesn’t help much if the heat-treat and machining capacity downstream can’t keep up, so the Rzeszów building is the less glamorous half of the fix.

It also deepens a long bet on Poland. RTX says the country is its largest investment and employee base outside the U.S., with roughly 9,500 people across Pratt & Whitney, Collins Aerospace and Raytheon. For U.S. aerospace suppliers and builders, the takeaway is that capacity for military and commercial engine parts is going up on both sides of the Atlantic at once, and the 2028 finish lines for Columbus and Rzeszów are tied together.
