Moog Inc. (NYSE: MOG.A and MOG.B) Space and Defense Group recently demonstrated its advanced Electromechanical Thrust Vector Control (EM TVC) system on the U.S. Air Force and Orbital ATK ground level static fire test of the Medium-Class Stage III (MCS-III) solid rocket motor. This test demonstrated the advanced Moog EM TVC technology being studied for the forthcoming Air Force Ground-Based Strategic Deterrent (GBSD) system.

"The Electro Mechanical Thrust Vector Control system was a key technology advancement demonstrated during the MCS-III test,” said Tom Stack, program manager of Orbital ATK’s Air Force Programs. “The system provided by Moog performed flawlessly during this test."

The test validates and supports one of several Moog thrust vector control architectures being evaluated under a two-year BAA award for GBSD Strategic Open Architecture Thrust Vector Control (TVC) System technology study. A key part of this effort is for Moog to build on its extensive TVC experience to develop state-of-the-art systems for nuclear survivability. EM TVC systems are proven to reduce life cycle cost because the technology has lower maintenance requirements and can be tested in silo unlike alternative technologies.

The EM TVC system used in this test is similar to the EM TVC systems Moog provides for the Orbital ATK Castor 30 rocket engine and the uppers stages of Delta IV and Atlas V expendable launch vehicles. Moog has successfully flown over fifty similar EM TVC systems and is proud to be a trusted partner to Orbital ATK and the U.S. Air Force.

Moog Inc. is a worldwide designer, manufacturer, and integrator of precision control components and systems. Moog’s high-performance systems control military and commercial aircraft, satellites and space vehicles, launch vehicles, missiles, automated industrial machinery, wind energy, marine and medical equipment.
