On June 18, 2018, President Donald Trump directed the Pentagon to begin planning for Space Force: a 6th independent military service branch to undertake missions and operations in the rapidly evolving space domain. The U.S. Space Force would be the first new military service in more than 70 years, following the establishment of the U.S. Air Force in 1947.
Vice President Mike Pence and the Department of Defense released more details about the planned space force on August 9, 2018, citing plans to create a separate combatant command, U.S. Space Command, in addition to an independent service overseen by a civilian secretary. It's not yet clear how many troops will serve in U.S. Space Force or how much it will cost to create. The new military service is set to be established by 2020, officials have said.
