Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, announced today it has been awarded a follow-on Rocket Motor Technical Services (RMTS) contract from the U.S. Missile Defense Agency (MDA) Targets and Countermeasures Directorate. Under the contract, Orbital ATK will primarily support MDA in the sustainment of Trident I (C4) and Orion motors for use in MDA targets and interceptor vehicles. Orbital ATK also provides services for CASTOR®, Orbus 1A and Oriole motors as well as various specialty support services such as radar signature testing and specialty tooling.

“Orbital ATK has more than 50 years of demonstrated performance providing aging and surveillance support of strategic motors for MDA, the Air Force and the Navy,” said Charlie Precourt, Vice President and General Manager of Orbital ATK’s Propulsion Systems Division. “As such, our world’s leading solid rocket motor expertise is helping ensure reliability and mission success for our customer.”

Under the RMTS contract, Orbital ATK will provide sustaining engineering, aging and surveillance testing and analysis, motor logistics, motor storage, motor disposal, static test support and flight test motor preparations for a five-year period. Target vehicles using C4 motors are on MDA’s flight manifest through the mid-2020s. Orion motors are used on both target vehicles and the Ground-Based Interceptor vehicle for the foreseeable future.

The majority of the work for this contract will be conducted at Orbital ATK’s Bacchus facility in Magna, Utah, with support as needed from several other Orbital ATK facilities across the country.
