The U.S. Space Force (USSF) is a new branch of the Armed Forces. It was established on December 20, 2019 with enactment of the Fiscal Year 2020 National Defense Authorization Act and will be stood-up over the next 18 months. The USSF was established within the Department of the Air Force, meaning the Secretary of the Air Force has overall responsibility for the USSF, under the guidance and direction of the Secretary of Defense. The official flag of the Space Force is derived from key and central elements of the Seal of the United States Space Force presented on a black field fringed in platinum with the words United States Space Force and Roman numerals MMXIX (2019) below the imagery.
