Second AEHF delivered

Lockheed Martin delivered the second Advanced Extremely High Frequency (AEHF) military communications satellite to Cape Canaveral Air Force Station, Fla., where it will be readied for an April 2012 liftoff aboard an Atlas V. The AEHF system will replace the five-satellite Milstar constellation. One AEHF satellite will provide greater total capacity than the entire Milstar system. Individual user data rates will be five times improved, providing transmission of tactical military communications, such as real-time video, battlefield maps and targeting data.
