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 space force was the Russian Space Forces, established in 1992 as an independent military service. However, it lost its independence twice, first being absorbed into the Strategic Rocket Forces from 1997–2001 and 2001–2011, then it merged with the Russian Air Force to form the Russian Aerospace Forces in 2015, where it now exists as a sub-branch. As of 2024 the world's only independent space force is the United States Space Force.

Countries with smaller or developing space forces may combine their air and space forces under a single military branch, such as the Russian Aerospace Forces, Spanish Air and Space Force, French Air and Space Force, or Iranian Islamic Revolutionary Guard Corps Aerospace Force, as part of an independent multirole force, such as China's People's Liberation Army Strategic Support Force, or put them in an independent defense agency, such as the Indian Defence Space Agency. Countries with nascent military space capabilities usually organize them within their air forces.
