Pratt & Whitney Invests US$25 Million to Expand Engine Manufacturing Facility in Niepołomice, Poland

Pratt & Whitney is investing US$25 million (PLN 95 million) to expand its manufacturing facility in Niepołomice, Poland, increasing production capacity for complex tubular assemblies used in commercial and military engines. The expansion is expected to be operational in 2028 and will create more than 120 jobs.

The Niepołomice site currently produces precision components for several engine programmes, including the GTF engine for commercial aircraft, the PW800 for business jets, and the F135, which powers all variants of the F-35 Lightning II fighter. Dariusz Stopa, general manager of Pratt & Whitney in Niepołomice, said "Poland plays a vital role as a key hub in Pratt & Whitney's global engine production," adding that "growing this team will increase our ability to meet global demand for advanced aircraft engines."

The Niepołomice investment is part of a broader US$125 million commitment to Pratt & Whitney facilities in Poland this year. It follows a recently announced US$100 million investment in Pratt & Whitney facilities in Rzeszów, aimed at increasing production capacity and adding advanced capabilities for processing isothermally forged parts for the GTF, F135 and F100 engines. The investment is supported by the Polish government through its Polish Investment Zone Programme. Poland is RTX's largest investment and employee base outside the United States, with more than 9,500 employees across its Collins Aerospace, Pratt & Whitney and Raytheon businesses in the country.

This expansion reflects how engine manufacturers concentrate specialised, capital-intensive processes like tubular assembly and isothermal forging in a small number of dedicated sites rather than spreading them across many plants, since the tooling and qualification costs favor scale at fewer locations. Pairing the Niepołomice expansion with the earlier Rzeszów investment shows a single supplier base serving three distinct engine families at once, meaning capacity added for one programme can flex to cover demand spikes in another.

Government incentive programmes such as Poland's Investment Zone Programme are a recurring feature of where OEMs choose to locate new capacity, since they lower the effective cost of the buildout without the manufacturer disclosing how much of the US$25 million the incentive offsets. What comes into view next is whether the 2028 completion date holds against current GTF and F135 delivery schedules, since a facility timed to open years out is a bet on demand that has to be validated by actual order intake between now and then.
