U.S. Space Force
The history of the United States Army began in 1775. From its formation, the United States Army has been the primary land based part of the United States Armed Forces. The Army's main responsibility has been in fighting land battles and military occupation. Until the 1940s, the Army was relatively small in peacetime.
In 1947, the Air Force became completely independent of the Army Air Forces. The Army was under the control of the War Department until 1947, and since then the Defense Department. (1)
