Contract Part of Multi-Year Study and Demonstration of Post-Boost
Propulsion System Technologies
DULLES, Va.Mar. 15, 2016--
Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense
technologies, announced today that its Defense Systems Group has signed
a contract with the U.S. Air Force (USAF) to research design and
development options for its intercontinental ballistic missile system
(ICBM). Part of a multi-year USAF Ground-Based Strategic Deterrent
program (GBSD), the award will be used to explore enhanced propulsion
capability through improvements and/or alternatives to current
post-boost propulsion systems.
Orbital ATK s effort will focus on trade studies and hardware
demonstrations aimed at improving post-boost propulsion system
effectiveness, reducing life-cycle costs, and increasing safety and
reliability for future ground-based strategic missile systems.
Orbital ATK s post boost technology offers the GBSD community with
years of experience supporting numerous systems, including the U.S. Navy
Trident II, said Pat Nolan, Vice President and General Manager of
Orbital ATK's Missile Products division of the Defense Systems Group.
In service since the 1960s, the current Minuteman III represents the
land-based component of the U.S. nuclear triad which, along with its
sea- and air-based counterparts, supports the nation s strategic
defense. Once development is completed for the new GBSD system, it will
begin replacing the Minuteman III starting in the late 2020s.
Orbital ATK Defense Systems Group is an industry leader in providing
innovative and affordable ammunition, precision and strike weapons,
electronic warfare systems, and missile components across air-, sea-,
and land-based systems.
