Atlas V launches secret satellite for US Space Force

Two satellites are on their way to orbit to assist the U.S. military monitor fast-moving threats.

First and second stages separated 4.5 minutes after liftoff, followed by a 6-minute Centaur engine burn

Two additional Centaur fires put the two satellites in geosynchronous orbit, 22,300 miles (35,900 km) above Earth. 

ULA reported on Twitter early Saturday that everything occurred as expected six hours after launch.

One of the two spacecraft, the Wide Field of View (WFOV) satellite, is a testing platform for new missile-surveillance technologies.

WFOV and USSF-12 Ring are secret payloads for national security, hence nothing is known about them.
