AEHF-4 Mission Launches

The Atlas V / Advanced Extremely High Frequency-4 mission lifted off in the early morning of October 17, virtually jumping off the launch pad as five solid rocket motors delivered nearly three million pounds of thrust.

The Atlas V in the 551 configuration lifted off at the beginning of the launch window at 12:15 a.m. Eastern time from Space Launch Complex-41 from Cape Canaveral, Florida. The AEHF-4 adds another satellite to a secure military communications constellation.

This launch was the 131st mission for ULA, the 50th ULA launch for the U.S. Air Force, and the 79th Atlas V.

This was a transition of sorts for Aerospace as well, as two leaders switch roles between launch and spacecraft programs: Susan Herbulock, the former principal director for the AEHF program, has been promoted to general manager of the Enterprise Ground and Launch Division; replacing her is Bryan Cooley, the former principal director for Atlas and Delta programs.
