Orbital ATK s Medium-Class Upper Stage Motor Provides New Capability
to Air Force
DULLES, Va.Nov. 11, 2015--
The U.S. Air Force and Orbital ATK (NYSE:OA) successfully conducted a
ground level static fire test of the Medium-Class Stage III (MCS-III)
solid rocket motor on November 5. This test was a demonstration of
advanced technologies being studied for use in the forthcoming Air Force
Ground-Based Strategic Deterrent (GBSD) system.

The new advanced technologies demonstrated are important stepping
stones for the future GBSD program, said Charlie Precourt, vice
president and general manager of Orbital ATK s Propulsion Systems
Division. This test of new propulsion technologies is a significant
achievement for our company and the Air Force.
Orbital ATK developed the high-performance upper stage motor for the
MCS-III program. The objectives of the static fire test were to
demonstrate an advanced strategic grade propellant, validate feasibility
of motor thrust reversal/thrust termination system in a graphite epoxy
case, and demonstrate a performance enhancing, vectorable nozzle with
electro-mechanical thrust vector control. Preliminary test results
indicate the motor performed within predictions.
The Air Force plans to replace Minuteman III propulsion elements with a
modern propulsion system as part of the GBSD program. The Air Force is
preparing for the upcoming development work by maturing and
demonstrating available technologies in a medium-class solid rocket
motor, applicable to the GBSD propulsion systems.
Orbital ATK has a successful history of designing, fabricating,
integrating, testing and delivering more than 3,800 motors in direct
support of Department of Defense missions. Orbital ATK s medium-class
stage motors could support multiple missions such as GBSD, Conventional
Strike Missile and Operationally Responsive Space.
The MCS-III program, which is managed by the Air Force Nuclear Weapons
Center at Hill Air Force Base in Utah, is conducted under the
Intercontinental Ballistic Missile Demonstration/Validation Propulsion
Application Program funding to support the demonstration of technologies
applicable to future strategic programs.
