Images of the airmen transferring to the new service branch during a Feb. 17 ceremony were posted Tuesday by Yokota Air Base on the photo-sharing website Flickr. They show the new guardians in formation wearing space blue name tapes in front of a projection of the Space Force’s futuristic delta logo. They join a service that was founded in late 2019 and charged with missions ranging from monitoring early warning systems that track potential threats to the U.S. homeland to ensuring the safety of American satellites.
