History Willmar Air Force Station was initially part of Phase II of the Air Defense Command Mobile Radar program. The Air Force approved this expansion of the Mobile Radar program on October 23, 1952. Radars in this network were designated “SM.” The station became operational on 1 July 1956 when the 721st Aircraft Control and Warning Squadron was moved to the station by the 31st Air Division. This site became operational in 1957 with the 721st AC&W Squadron operating a variety of radars including AN/FPS-6, AN/FPS-8, AN/MPS-7, and AN/FPS-3 sets, and initially the station functioned as a Ground-Control Intercept (GCI) and warning station.

Air Defense Command
Aerospace Defense Command was a major command (military formation), command of the United States Air Force, responsible for continental air defense. It was activated in 1968 and disbanded in 1980. Its predecessor, Air Defense Command, was established in 1946, briefly inactivated in 1950, reactivated in 1951, and then redesignated ''Aerospace'' rather than ''Air'' in 1968. Its mission was to provide air defense of the Continental United States (CONUS). It directly controlled all active measures, and was tasked to coordinate all passive means of air defense. Air defense during World War II Continental United States air defense forces during World War II were initially under the command of the four air districts – Northeast Air District, Northwest Air District, Southeast Air District, and Southwest Air District. The air districts were established on 16 January 1941, before the Pearl Harbor attack. The four air districts also handled USAAF combat training with the Army Ground F ...

Snelling AFS
Fort Snelling is a former military fortification and National Historic Landmark in the U.S. state of Minnesota on the bluffs overlooking the confluence of the Minnesota and Mississippi Rivers. The military site was initially named Fort Saint Anthony, but it was renamed Fort Snelling once its construction was completed in 1825. Before the American Civil War, the U.S. Army supported slavery at the fort by allowing its soldiers to bring their personal enslaved people. These included African Americans Dred Scott and Harriet Robinson Scott, who lived at the fort in the 1830s. In the 1840s, the Scotts sued for their freedom, arguing that having lived in "free territory" made them free, leading to the landmark United States Supreme Court case ''Dred Scott v. Sandford''. Slavery ended at the fort just before Minnesota statehood in 1858. The fort served as the primary center for U.S. government forces during the Dakota War of 1862. It also was the site of the encampment where eastern Dako ...

Military Installations Established In 1956
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ...

Aerospace Defense Command Military Installations
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space R ...

7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear.
