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 absorbed into the Strategic Rocket Forces between 1997 and 2001 and between 2001 and 2011. Then it merged into the Russian Air Force to form the Russian Aerospace Forces in 2015, where it is a sub-branch. As of 2026, there are two independent space forces: the United States Space Force and China's People's Liberation Army Aerospace 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, 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.

History

The first artificial object to cross the Kármán line, the boundary between air and space, was MW 18014, an A-4 rocket launched by the German Heer on 20 June 1944 from the Peenemünde Army Research Center. The A4, more commonly known as the V-2, was the world's first ballistic missile, used by the Wehrmacht to launch long-range attacks on the Allied Forces on the Western Front during the Second World War. The designer of the A4, Wernher von Braun, had aspirations to use them as space launch vehicles.
