The U.S. Air Force’s fifth Advanced Extremely High Frequency satellite, designed for secure, jam-resistant communications, is set for launch aboard a United Launch Alliance Atlas 5 rocket. These photos show the AEHF 5 satellite during encapsulation inside the Atlas 5’s payload shroud.
The AEHF 5 satellite, built by Lockheed Martin, will join four other satellites in the Air Force’s protecting communications network providing secure data, voice and video links to the military and government leaders.
The spacecraft weighs around 13,600 pounds (6,168 kilograms) fully fueled. The Atlas 5 rocket set to launch with the AEHF 5 satellite will fly in the “551” configuration — the most powerful Atlas 5 variant — with a 5.4 meter (17.7-foot) diameter payload fairing produced by Ruag Space and five solid rocket boosters from Aerojet Rocketdyne.

A European-built Ariane 5 rocket launched Tuesday with a U.S.-made communications satellite for Tokyo-based Sky Perfect JSAT and a South Korean environmental observatory. The heavy-lift Ariane 5 launcher took off from the Guiana Space Center in Kourou, French Guiana, at 5:18 p.m. EST (2218 GMT; 7:18 p.m. French Guiana time).
SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Thursday, heading due east over the Atlantic Ocean to deliver the Es’hail 2 communications satellite into orbit around 32 minutes later.
SpaceX’s first upgraded Falcon 9 “Block 5” rocket was raised vertical at launch pad 39A early Thursday in preparation for liftoff from the Kennedy Space Center, debuting enhancements aimed at making the booster more reusable and more reliable.
