A2100 satellite reaches milestone

The Lockheed Martin A2100 communications satellite series has reached a milestone by chalking up over 400 cumulative years of successful, in-orbit operations. The orbiting fleet consists of 45 commercial and U.S. government communication satellites equipped with over 1,500 transponders transmitting data, video and audio for operators worldwide. In addition to commercial applications, the A2100 satellite is the platform for communications programs for the U.S. government, including the Advanced Extremely High Frequency and Mobile User Objective System.
