CAPE CANAVERAL AIR FORCE STATION, Fla., Aug. 8, 2019 (ULA PR) – A United Launch Alliance (ULA) Atlas V rocket carrying the fifth Advanced Extremely High Frequency (AEHF) communications satellite for the U.S. Air Force Space and Missile Systems Center lifted off from Space Launch Complex-41 on August 8 at 6:13 a.m. EDT.

This marked the 80th successful launch of an Atlas V rocket, which has successfully launched and precisely delivered the entire AEHF constellation on orbit. ULA has a track record of 100 percent mission success with 134 successful launches.

ULA Delays Atlas V, Delta IV Missions

CAPE CANAVERAL AIR FORCE STATION, Fla. (ULA PR) — The United Launch Alliance (ULA) Atlas V551 rocket carrying the Lockheed Martin-built Advanced Extremely High Frequency 5 (AEHF-5) satellite for the U.S. Air Force Space and Missile Systems Center is delayed, due to an anomaly during component testing at a supplier which has created a cross-over concern. 

Additional time is needed for the team to review the component anomaly and determine if any corrective action is required to the launch vehicle. Launch of the AEHF-5 mission is now targeted for no earlier than Thursday, Aug. 8, 2019.

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.

The AEHF-5 launch will mark the 80th Atlas V mission since the inaugural launch in 2002 and the 10th in the 551 configuration. The rocket features a kerosene-fueled common core booster, five solid rocket boosters, the hydrogen-fueled Centaur upper stage and a five-meter-diameter payload fairing.

The ULA Delta IV rocket carrying the GPS III SV02 mission for the U.S. Air Force Space and Missile Systems Center is delayed, due to an anomaly during component testing at a supplier which has created a cross-over concern. 

Upon further evaluation, additional time is needed to replace and retest the component on the launch vehicle. Launch of the GPS III SV02 mission is now targeted for no earlier than Thursday, Aug. 22, 2019.

Design Evolution: Lockheed Martin is using 3-D Printed Parts for U.S. Military Satellites

New process cuts more than four months out of the manufacturing lead time for a component onboard the U.S. Air Force’s AEHF-6 satellite

SUNNYVALE, Calif. (Lockheed Martin PR) — When the U.S. Air Force’s sixth Advanced Extremely High Frequency (AEHF-6) satellite launches into space, a 3-D printed part will be along for the ride. A Remote Interface Unit, an aluminum electronic enclosure designed to hold avionic circuits, will be the first 3-D printed part certified for use on a Lockheed Martin (NYSE: LMT) military satellite.
