Moog (rhymes with "rogue") makes precision-control components and systems used in aerospace products, industrial machinery, and medical equipment. Servoactuators, Moog's core product, receive electrical signals from computers and then perform specific actions. Using its servoactuators, Moog builds flight and control systems for commercial and military aircraft, as well as hydraulic and electrical controls for automated industrial machinery, wind turbines, and control systems for satellites and spacecraft, launch vehicles, and missiles. It also makes infusion therapy pumps, slip rings for CT scanners, and motors used in devices for sleep apnea. Customers in the US make up more than half of sales.
