Moog Inc.

Moog started with a single idea in 1951, when Bill Moog patented the electrohydraulic servo valve that let a small electrical signal control a much larger hydraulic force with precision. That patent became the seed of a company now built around motion control across four segments: Aircraft Controls, Space and Defense, Industrial, and a smaller Components business that supplies slip rings and related hardware to the other three. Aircraft Controls remains the largest of the group, supplying flight control actuation for commercial airliners including the Boeing 787 and Airbus A350, work that runs alongside its military business rather than in a separate division. On the defense side, Moog's footprint spans air, land, sea, and space.

In air defense, it builds actuation and missile steering systems for guided munitions and interceptors, along with the flight control actuators used on the F-35 Lightning II. In land defense, the company supplies turreted weapon systems, fast ammunition handling hardware, and components for counter-unmanned aerial system platforms, positioning it as a motion-control supplier to combat vehicle and force protection programs rather than a vehicle builder itself. Its naval defense work centers on undersea actuation systems and motion control hardware built to survive the pressure and corrosion of shipboard and submarine environments, an area where reliability matters as much as precision. Space is where Moog's history runs deepest outside aviation.

The company has supplied propulsion, positioning, and actuation hardware for NASA missions going back decades, and its space business today includes satellite buses, hexapod positioning systems, and slip rings that let satellites rotate solar arrays and antennas without tangling their wiring. That space and defense combination sits under one roof at Moog in a way that mirrors how the company thinks about its business generally: less about a signature product and more about a core competency, precise motion and force control, applied wherever a customer needs something to move exactly as commanded under demanding conditions. The company operates manufacturing, engineering, and sales facilities across roughly two dozen countries, reflecting decades of growth built on winning content on individual programs rather than prime contracting whole platforms. Its work spans commercial aviation, military aircraft, missile systems, naval vessels, spacecraft, and industrial machinery, with the defense and space portion of the business consistently representing a substantial share of total revenue alongside its aerospace commercial work.
