A United Launch Alliance Atlas V rocket successfully launched the Advanced Extremely High Frequency-1 (AEHF-1) satellite for the Air Force from Space Launch Complex- 41 on August 14, 2010. The AEHF constellation of four satellites will provide 10 times greater capacity and channel data rates six times higher than that of the existing Milstar II communications satellites. AEHF-1 will be joined by the next two AEHF satellites to be launched during the next two years by ULA.
