Reference excerpt

While the United States Space Force was established in December 2019, the history of the U.S. Department of Defense in space can be traced back to the aftermath of the Second World War. General Henry H. Arnold, chief of the United States Army Air Forces, identified space as a crucial military arena decades before the first spaceflight. The United States Air Force gained its independence from the Army on 18 September 1947. The Air Force began developing space and ballistic missile programs, while competing with the United States Army and United States Navy for space missions. In 1954, the Air Force created its first space organization, the Western Development Division, under the leadership of General Bernard Schriever. The Western Development Division and its successor organization, the Air Force Ballistic Missile Division, were instrumental in developing the first United States military launch vehicles and spacecraft, competing predominantly with the Army Ballistic Missile Agency under the leadership of General John Bruce Medaris and former German scientist Wernher von Braun. The launch of Sputnik 1 spurred a massive reorganization of military space and the 1958 establishment of the Advanced Research Projects Agency was a short-lived effort to centralized management of military space, with some fearing it would become a military service for space, with authorities being returned to the services in 1959. The establishment of NASA in 1958, however, completely decimated the Army Ballistic Missile Agency, resulting in the Air Force Ballistic Missile Division serving as the primary military space organization. In 1961, the Air Force was designated as the Department of Defense's executive agent for space and Air Research and Development Command was reorganized into Air Force Systems Command, with the Air Force Ballistic Missile Division being replaced by the Space Systems Division - the first Air Force division solely focused on space. In the 1960s, military space activities began to be operationalized, with Aerospace Defense Command taking control of missile warning and space surveillance on behalf of NORAD, Strategic Air Command assuming the weather reconnaissance mission, and Air Force Systems Command operating the first generations of communications satellites on behalf of the Defense Communications Agency. In 1967, the Space Systems Division and Ballistic Missiles Division were merged to form the Space and Missile Systems Organization, which began to develop the next generation of satellite communications, space-based missile warning, space launch vehicles and infrastructure, and the predecessor to the Global Positioning System. Space forces also saw their first employment in the Vietnam War, providing weather and communications support to ground and air forces. The disjointed nature of military space forces across three military commands resulted in a reevaluation of space force organization within the Air Force. In 1979, the Space and Missile Systems Organization was split, forming the Space Division, and in 1980, Aerospace Defense Command was inactivated and its space forces transferred to Strategic Air Command. Resulting from internal and external pressures, including an effort by a congressman to rename the Air Force into the Aerospace Force and the possibility that President Reagan would direct the creation of a space force as a separate military branch, the Air Force directed the formation of Air Force Space Command in 1982. During the 1980s, Air Force Space Command absorbed the space missions of Strategic Air Command and the launch mission from Air Force Systems Command. Space forces provided space support during the Falklands War, United States invasion of Grenada, the 1986 United States bombing of Libya, Operation Earnest Will, and the United States invasion of Panama. The first major employment of space forces culminated in the Gulf War, where space forces proved so critical to the U.S.-led coalition, that it is sometimes referred to as the first space war. Following the end of the Gulf War, the Air Force came under intense congressional scrutiny by seeking to artificially merge its air and space operations into a seamless aerospace continuum, without regard for the differences between space and air. The 2001 Space Commission criticized the Air Force for institutionalizing the primacy of aviation pilots over space officers in Air Force Space Command, for stifling the development of an independent space culture, and not paying sufficient budgetary attention to space. The Space Commission recommended the formation of a Space Corps within the Air Force between 2007 and 2011, with an independent Space Force to be created at a later date. The September 11 attacks derailed most progress in space development, resulting in the inactivation of United States Space Command and beginning a period of atrophy in military space. The only major change to occur was the transfer of the Space and Missile Systems Center from Air Force Materiel Command to Air Force Space Command. Following the inactivation of U.S. Space Command in 2002, Russia and China began developing sophisticated on-orbit capabilities and an array of counter-space weapons. On 29 August 2019, United States Space Command was reestablished as a geographic combatant command. In response to advances by the Russian Space Forces and Chinese People's Liberation Army Strategic Support Force and frustrated by the Air Force's focus on fighters at the expense of space, Democratic Representative Jim Cooper and Republican Representative Mike Rogers introduced a bipartisan proposal to establish the United States Space Corps in 2017. While the Space Corps proposal failed in the senate, in 2019, the United States Space Force was signed into law, with Air Force Space Command becoming the United States Space Force.

Early military space development (1946–1957) On 18 September 1947, the Army Air Forces gained their independence as the United States Air Force. While the Air Force claimed that military space was its domain, the new service prioritized conventional aircraft over ballistic missile and space development.

Worked examples

Example 1 — a first encounter with History of the United States Space Force

Start with the simplest possible case. Write down what History of the United States Space Force claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to History of the United States Space Force before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about History of the United States Space Force ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of History of the United States Space Force

In research: History of the United States Space Force appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses History of the United States Space Force in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: History of the United States Space Force is common in secondary-school and first-year university syllabi. It links to neighbouring topics History of spaceflight, History of the United States Armed Forces by service branch, History of the United States Space Force, so understanding it makes those chapters shorter.
In everyday life: Look for History of the United States Space Force outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
