Thrust Vector Control Systems
Moog leads the industry in the design, development and production of flight control systems for launchers and space vehicles. Our actuators, control electronics and subsystem integration enable reliable thrust vector control (TVC) for several different launch vehicles.
EM TVC systems have been produced for a wide range of applications, implementing a variety of fault tolerant architectures and actuator configurations to meet the specific program needs. EM actuators are capabile of 70+ hp, providing producible scalability for high-powered applications.
The Common EMA (CEMA) System developed for Atlas Centaur and Delta IV EELV upper stage TVC Systems was derived from high-reliability flight systems. This modular architecture allows for common solutions for two+ diferent engines.
Programs: Antares CASTOR 30, LCS I, Atlas Centaur, Delta IV EELV

EH TVC systems have supported critical U.S. space programs and continuously developed, producing systems ranging from simplex, zero fault tolerant systems for commercial launch vehicles to triplex, single fault tolerant systems for NASA launch vehicles.
Programs: Saturn, Titan, Trident, Space Shuttle, Delta, Space Launch System (SLS)
EHA combines the heritage EH piston-cylinder centerline with a selfcontained, electrically driven hydraulic power source. The vehicle-based centralized hydraulic power supply, connecting infrastructure and servovalve(s) are replaced with one or more electric motor/pump assemblies in a closed system. EHAs can be considered an EMA with a hydraulic transmission rather than a mechanical geared transmission.
EHAs are being considered for future human-rated spaceflight.
