Rolls-Royce has completed a $1 billion, decade-long investment in its manufacturing, assembly and testing facilities in Indiana, strengthening its role in the US defence industry and expanding advanced manufacturing capabilities in the state. The investment is the largest Rolls-Royce has made in the United States. It has modernised manufacturing operations at the company’s Indianapolis campus and added full engine-testing capabilities, including new ground test facilities and an altitude test facility in West Lafayette.
Indianapolis now produces more Rolls-Royce defence products than any other location in the world. The campus manufactures and tests engines for a range of defence and commercial platforms, including future engines for the US Air Force B-52 strategic bomber and the US Army’s MV-75 Cheyenne. It also supports current programmes including the V-22 Osprey, US Navy MQ-25A Stingray and C-130J.
“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,” said Adam Riddle, President, Defense, and CEO, Rolls-Royce North America. “We made this investment because it was the right thing to do for US national security and for the future of Rolls-Royce.”
The investment has also strengthened employment and the company’s wider supplier network in Indiana. Rolls-Royce employs approximately 3,500 people in Indianapolis, including a skilled UAW workforce, while supporting thousands of additional jobs through its Indiana supply chain.
Indiana Governor Mike Braun said the investment reflected confidence in the state’s manufacturing workforce and economic capabilities. The project has also received support from Indiana’s congressional delegation. Senator Todd Young said the investment demonstrated the importance of producing advanced military technology in the United States, while Senator Jim Banks highlighted the role of Indianapolis-built engines in supporting American military aircraft.
Members of the Indiana congressional delegation, including Representatives André D Carson, Marlin Stutzman, Erin Houchin and Jefferson Shreve, also welcomed the investment and its expected contribution to manufacturing and defence-related employment. Indianapolis Mayor Joe Hogsett said the investment reinforced the city’s position in advanced manufacturing and recognised the strength of its skilled workforce.
Rolls-Royce has invested more than $1.5 billion in US facilities and nearly $2.5 billion in research and development over the past decade. In 2024, its US operations contributed $6.2 billion to the US economy and, including research and development spillover, supported more than 30,000 jobs across 26 states.
Rolls-Royce employs more than 5,000 people in the United States and works with hundreds of American suppliers across 34 locations in 26 states. Globally, Rolls-Royce serves customers in more than 100 countries, including airlines, aircraft leasing companies, armed forces, navies, marine operators and industrial customers.
The company reported $27.05 billion in underlying revenue and $4.7 billion in underlying operating profit in 2025. Through its transformation programme, Rolls-Royce is focused on strengthening its competitiveness, resilience and capacity to develop technologies for its customers.
