Rolls-Royce has completed a $1 billion, decade-long investment programme across its Indiana manufacturing, assembly and test facilities. The work has modernised advanced manufacturing at the Indianapolis campus and added full engine-test capability, including new ground test facilities and an altitude test facility in West Lafayette. It is the largest investment the company has made in the United States, and more Rolls-Royce defence products are built in Indianapolis than anywhere else in the world.

The campus tests and builds engines for a range of defence and commercial platforms, including future engines for the U.S. Air Force B-52 bomber and the U.S. Army's MV-75 Cheyenne, alongside current engines for the V-22 Osprey, the U.S. Navy's MQ-25A Stingray and the C-130J.

Adam Riddle, President, Defense, and CEO, Rolls-Royce North America, says: “This billion-dollar investment is about more than buildings and test cells, it is about delivering for the American warfighter, on time and at the standard our customers expect. We made this investment because it was the right thing to do for U.S. national security and for the future of Rolls-Royce.”

Rolls-Royce employs approximately 3,500 people in Indianapolis, including a skilled UAW workforce, and supports thousands more jobs through its Indiana supply chain. The Indianapolis campus is also home to LibertyWorks, the company's advanced-research organisation, which has worked at the forefront of high-temperature materials and propulsion for decades, anchored by a $75 million, ten-year alliance with Purdue University.

Across the United States, Rolls-Royce has invested more than $1.5 billion in its facilities and nearly $2.5 billion in research and development over the past decade. In 2024 the company's U.S. operations contributed $6.2 billion to the national economy and, including R&D spillover, supported more than 30,000 jobs across 26 states.
