The U.S. Army transferred its satellite ground stations to the Space Force on Monday as the latest step in establishing the sixth branch of the U.S. military devoted to demonstrating national dominance in space. The U.S. Department of Defense announced the transfer last year, which took effect on August 15. All in all, 15 global units with 319 military and 259 civilian personnel from the Army and Navy will transfer to the Space Force’s Space Delta 8, the unit responsible for satellite communications, as stated in the announcement. Space Delta 8 is now in charge of the Wideband Global Satcom and Defense Satellite Communications System, a constellation of military communication satellites, as well as the Global Positioning System constellation for both military and civilian users, among other communication satellites, according to Space News. These satellites were originally built by the U.S. Air Force, and later operated by the military for decades.
