ARLINGTON, Va., Jan. 7, 2013 /PRNewswire/ --ATK (NYSE: ATK) announced today
it was awarded a contract from the U.S. Air Force Space and Missile Systems
Center (SMC) Defense Weather Systems Directorate to execute a study of
Network-Centric Small Satellites as an element of SMC's Weather Satellite
Follow-On Activities.

This study will provide comprehensive insight into the capabilities and
characteristics of a 21st century weather data service that can systematically
augment the legacy Defense Meteorological Satellite Program (DMSP). The study
will focus on two aspects of such a mission system: 1) net-centric
architectures, and; 2) small, agile, cost-effective heritage spacecraft buses
that can be used to support a variety of future weather payloads.

Net-centric architectures can enable an orderly transition from historically
stove-piped systems to a true 21^st century system that provides for rapid
processing and dissemination of key weather data directly to the warfighter.
Systems engineering trade studies will define a distributed ground system that
utilizes commercial infrastructure to the greatest extent possible to enable
cost-effective, robust, faster data distribution for weather and other

Small and agile spacecraft concepts based on the heritage ATK A200 spacecraft
bus (previously used for both the TacSat-3 and ORS-1 spacecraft) will be
developed to demonstrate ATK's ability to host candidate Weather Satellite
Follow-on (WSF) instruments and to provide a path to affordable and reliable
spacecraft. ATK has, through the success of NASA's EO-1 and THEMIS, and the
military's TacSat-3 and ORS-1 programs, proven itself as an industry leader in
the design, fabrication, integration, and test of innovative and
cost-effective spacecraft systems.

"ATK is delighted to have this opportunity to play a key role with Space and
Missile Systems Center in an early exploration of disaggregated, affordable,
resilient architectures," said Tom Wilson, ATK Space Systems vice president
and general manager. "We support the U.S. Air Force Space Command and SMC
Space Modernization Initiative that could change the future of military space
