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.

The Air Force will launch a second pair of small security probes 22,300 miles above the Earth using a Delta 4 rocket on Friday to alert ground controllers of impending space collisions and monitor potential meddling with U.S. orbiting assets.
SpaceX called off a planned launch attempt Saturday to deploy the next batch of satellites for the Starlink broadband network. Two commercial Earth-observing satellites for BlackSky are also awaiting a ride into orbit on the Falcon 9 rocket from pad 39A at the Kennedy Space Center in Florida.
United Launch Alliance called off a test-firing of the company’s first flight-rated Vulcan Centaur rocket at Cape Canaveral Thursday to troubleshoot a problem with the booster’s engine ignition system.
