Space Force
A space force is a military branch of a nation's armed forces that conducts military operations in outer space and space warfare. The world's first and, as of 2021, only independent space force is the United States Space Force, established on 20 December 2019. The Russian Federation previously had the Russian Space Forces organized as independent troops from 1992 to 1997 and 2001 to 2011, however it was not organized as a military service. Countries with smaller or developing space forces may combine their air and space forces under a single military branch, such as in the Russian Aerospace Forces, French Air and Space Force, or Iranian Islamic Revolutionary Guard Corps Aerospace Force, or put them in an independent defense agency, such as the Russian Space Forces from 1992-1997 and 2001-2011 or the Indian Defence Space Agency.
