During the 1960s and 1970s, Air Force space forces were organized within Aerospace Defense Command for missile defense and space surveillance forces, Strategic Air Command for weather reconnaissance satellites, and Air Force Systems Command for satellite communications, space launch, and space development systems. In 1982, U.S. Air Force space forces were centralized in Air Force Space Command, the first direct predecessor to the U.S. Space Force. U.S. space forces were first employed in the Vietnam War, and continued to provide satellite communications, weather, and navigation support during the 1982 Falklands War, 1983 United States invasion of Grenada, 1986 United States bombing of Libya, and 1989 United States invasion of Panama. The first major employment of space forces culminated in the Gulf War, where they proved so critical to the U.S.-led coalition, that it is sometimes referred to as the first space war. The first discussions of creating a military space service in the United States occurred in 1958, with the idea being flouted by President Reagan as well in 1982. The 2001 Space Commission argued for the creation of a Space Corps between 2007 and 2011 and a bipartisan proposal in the U.S. Congress would have created a Space Corps in 2017. On 20 December 2019, the United States Space Force Act, part of the National Defense Authorization Act for 2020, was signed, creating an independent space service by renaming and reorganizing Air Force Space Command into the United States Space Force.
