Primary Industries in Los Angeles

Los Angeles’s strongest manufacturing sectors — and the precision parts we machine for each.

Aerospace

Flight-critical precision parts

Los Angeles is the birthplace of American aerospace — SpaceX builds Falcon and Starship hardware in Hawthorne, Northrop Grumman assembles the B-21 Raider in Palmdale, Boeing operates satellite programs in El Segundo, and Relativity Space and Rocket Lab push next-gen launch vehicle manufacturing across the metro. JPL in Pasadena drives deep-space exploration machining demand.

Defense

Mil-spec components & assemblies

Los Angeles remains the nation's largest defense manufacturing hub — Northrop Grumman's B-21 Raider program in Palmdale, Raytheon's El Segundo missile division, Boeing's satellite operations in El Segundo, and L3Harris sensors in the South Bay generate billions in annual machining demand.

Medical Devices

Surgical tools & implant components

Los Angeles is home to Edwards Lifesciences' transcatheter heart valve operations in nearby Irvine, Masimo's patient monitoring systems in Irvine, and ICU Medical's infusion therapy devices in San Clemente. UCLA Health, Cedars-Sinai Medical Center, and the Keck School of Medicine at USC fuel clinical research demand for prototype surgical instruments and implantable devices across the region.
