CAPE CANAVERAL AIR FORCE STATION, Fla., June 28, 2019 (ULA PR) — The United Launch Alliance (ULA) Atlas V rocket carrying the fifth Advanced Extremely High Frequency (AEHF-5) mission for the U.S. Air Force Space and Missile Systems is now targeted for Wednesday, July 17, 2019 at 7:12 a.m. ET, with a two-hour launch window.

The AEHF-5 mission will launch from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla.

Mission Information: An Atlas V 551 rocket will launch the fifth communications satellite in the Lockheed Martin-built AEHF series for the U.S. Air Force Space and Missile Systems Center. AEHF satellites provide highly-secure, jam-proof connectivity between U.S. national leadership and deployed military forces. Atlas V rockets successfully launched the first four AEHF satellites in 2010, 2012, 2013 and 2018.

Launch Notes: The AEHF-5 launch will mark the 80th Atlas V mission since the inaugural launch in 2002 and the 10th in the 551 configuration.

About Atlas V 551: ULA’s Atlas V rocket is a workhorse for the U.S. military, intelligence community and scientific researchers. Developed as a modular vehicle, each Atlas V is tailored to the needs of its passenger by adding as many as five side-mounted solid rocket boosters for increased lift performance and a variety of available payload fairings in various diameters and lengths to protect satellites during atmospheric ascent.

The high-energy Centaur upper stage, which has been used to send spacecraft to every planet in our solar system, is incorporated into Atlas V to deliver the payloads to their intended destinations.
