What Essex Industries does

Essex Industries is a family-owned aerospace and defense manufacturer founded in 1947 in St. Louis, Missouri, specializing in precision electromechanical components, cryogenic liquid oxygen (LOX) systems, and human-machine interface controls. The company serves military aerospace, commercial aviation, air medical transport, and aerospace contractors across more than 100 product SKUs organized into four primary lines: Platform Controls (HOTAS grips, throttle grips, control wheels, and weapons system controllers for F-35, F-22, F-16, F/A-18, C-130J, C-17, KC-46, Bell 525, Abrams M1A2, and Bradley); Liquid Oxygen Equipment (5L to 500-gallon converters, medical oxygen systems such as BMOS and MMOS, and the Battlefield Oxygen Sustainment System); Emergency Breathing Equipment (PBE, EPOS, SCU, and VRU+ smoke hoods, with PBE used by 90% of U.S. commercial airlines); and Aircraft Components (flame arrestors installed across all Boeing commercial aircraft, valves, pulsation dampeners, regulators, and cryogenic fittings).

The company generates revenue through custom-engineered hardware sales on a quote-based pricing model with multi-year contracts, supplemented by build-to-print contract manufacturing services and aftermarket maintenance, repair, and overhaul for LOX converters and platform controls. Distribution is primarily direct enterprise sales to defense primes, government procurement, and commercial airlines, with regional distributors in Europe and Asia-Pacific. Essex holds an unusually dense certification portfolio (AS9100D, ISO 9001:2015, NADCAP, FAA TSO-C116/C99, EASA Part 145, UK CAA Part 145, CAAC, ANAC, FAA PMA PQ3409CE, FDA GMP, DoD Quality System Qualification, ASME U-Stamp) and operates 180,000+ square feet of manufacturing across five U.S. facilities in St. Louis (headquarters plus Chivvis and Sunnen sites), Huntington Beach, California, and Milford, Connecticut, employing 400+ people.

The company has expanded through both organic program wins and three strategic acquisitions since 2019: Momeni Engineering in January 2019, Stevens Manufacturing Company in February 2021, and Precision Aerospace, Inc. on October 24, 2022. Third-generation family member Evan Waldman serves as CEO, with second-generation Keith Guller and Mickey Waldman serving as Board Directors; the company remains independently owned with no external parent or private equity backing. Key customers include the U.S. Army, U.S. Air Force, Japanese Ministry of Defense, major U.S. commercial airlines, and numerous military aircraft platforms; in July 2026 the company secured positions on the MV-75 Cheyenne FLRAA program and an undisclosed next-generation U.S. defense aircraft program, extending its designed-in footprint into the next procurement cycle.
