The U.S. Space Force was established Dec. 20, 2019 when the National Defense Authorization Act was signed into law (with bi-partisan support), creating the first new branch of the armed services in 73 years. The establishment of the USSF resulted from widespread recognition that Space was a national security imperative. When combined with the growing threat posed by near-peer competitors in space,it became clear there was a need for a military service focused solely on pursuing superiority in the space domain.
