Pratt & Whitney, a unit of RTX Corporation (NYSE: RTX), announced a $100 million investment to expand its facility in Rzeszów, Poland, to increase production capacity for commercial and military engines.

The company will construct a new facility housing specialized capabilities for processing isothermally forged parts, including heat treatment, sonic machining and inspection operations. The expansion supports production of GTF, F135, and F100 engines.

This investment follows a previously announced $200 million investment in a seventh isothermal forging press at Pratt & Whitney's Columbus Forge facility in Georgia. Both projects are expected to be fully operational by 2028 and will enable a 30% increase in output of critical engine parts, including rotating compressor and turbine disks.

"This investment reflects our continued commitment to increase production capacity for our customers and deliver more, faster," said Piotr Owsicki, general manager of Pratt & Whitney in Rzeszów.

Poland represents RTX's largest investment and employee base outside the United States, with more than 9,400 employees across its Collins Aerospace, Pratt & Whitney and Raytheon businesses in the country. Pratt & Whitney's Polish sites manufacture critical engine components including the GTF fan drive gear system and F100 static structures.

RTX reported 2025 sales of more than $88 billion and employs over 180,000 people globally. The company is headquartered in Arlington, Virginia.
