Indiana’s aerospace and aviation sector combines advanced manufacturing, aircraft propulsion, maintenance, engineering, and research. Rolls-Royce operates major manufacturing, assembly, testing, and engineering activities in Indianapolis, while GE Aerospace assembles and overhauls commercial jet engines in Lafayette. Purdue University further strengthens the sector through aerospace education and advanced flight research.

Indiana’s aerospace ecosystem is anchored by major propulsion manufacturers and supported by university research, aviation training, maintenance operations, and a deep advanced-manufacturing base.
Rolls-Royce Corporation
Rolls-Royce’s Indianapolis operations employ approximately 4,000 people in manufacturing, assembly, testing, engineering, and support roles. The site works across defense, civil small and medium engines, helicopters, marine systems, and advanced technology, and Rolls-Royce states that more of its products are built in Indianapolis than at any other location.
GE Aerospace
GE Aerospace’s Lafayette facility supports new assembly of LEAP and Passport jet engines as well as overhaul work for the LEAP engine. The plant connects Indiana technicians directly with commercial aircraft-engine manufacturing, inspection, assembly, testing, and maintenance operations.
Purdue University & Purdue Applied Research Institute
Purdue supports Indiana’s aerospace ecosystem through aerospace engineering, aviation technology, propulsion research, hypersonics, and advanced manufacturing. Its 65,000-square-foot Hypersonics and Applied Research Facility includes the HYPULSE shock tunnel, the Hypersonics Advanced Manufacturing Technology Center, and development of a Mach 8 quiet wind tunnel.
