T-sat Demise Poses Bandwidth Challenge

摘要

The U.S. Defense Department's decision to cancel the $26 billion Transformational Satellite (T-Sat) communications system raises questions about how it will meet the military's skyrocketing requirement for secure communications links, particularly for mobile forces.rnIn announcing the decision April 6, Defense Secretary Robert Gates said the Pentagon will instead procure more of the previous-generation Advanced Extremely High Frequency (AEHF) satellites from prime contractor Lockheed Martin Space Systems of Sunnyvale, Calif. The Air Force has also indicated it will procure more Wideband Global Satcom (WGS) craft from Boeing Space and Intelligence Systems of Seal Beach, Calif.
