Primary Industries in St. Louis

St. Louis’s strongest manufacturing sectors — and the precision parts we machine for each.

Aerospace

Flight-critical precision parts

St. Louis is Boeing's military aircraft headquarters — the F-15 Eagle, F/A-18 Super Hornet, EA-18G Growler, and T-7A Red Hawk trainer are all designed and assembled here. The MQ-25 Stingray autonomous refueling drone also originates from Boeing's St. Louis campus, driving massive demand for flight-critical aerostructures, avionics housings, and weapons system components.

Automotive

Performance & aftermarket parts

St. Louis sits at the center of a major auto-assembly corridor — the GM Wentzville Assembly builds mid-size trucks and vans, Ford's Claycomo plant (Kansas City side) builds the F-150, and Stellantis' Belvidere operations are within supply reach. Tier 1 players like Hussmann (Panasonic), Energizer Holdings, and a network of precision machining shops serve powertrain and interior-trim programs across the metro.

Medical Devices

Surgical tools & implant components

St. Louis's medical device sector is anchored by Benson Hill's biomedical platform, Mallinckrodt Pharmaceuticals' device-drug combination products, and Sigma-Aldrich's (MilliporeSigma) laboratory instrument manufacturing. Stereotaxis develops robotic navigation systems for cardiac procedures, Washington University School of Medicine and BJC HealthCare drive clinical trial demand, and a network of precision manufacturers serves the region's growing medtech cluster.
