Construction of Fairmont State Airfield by the United States Army Air Forces began on September 17, 1942. It was one of eleven training airfields built in Nebraska during World War II. Shortly after construction began, a railroad spur was built from Fairmont to the site to haul materials for the construction. About 1,000 laborers were hired to build the base, and the small towns of Geneva (pop. 1,888) and Fairmont (pop. 800) were hard pressed to find housing for the workers. Early in the construction, the facility was referred to as the Fairmont Satellite Airfield, and was designated a satellite of the Topeka Army Air Base in Kansas, however by early 1943, the name was changed to the Fairmont Army Airfield, as its mission was determined to be a training facility for heavy bomber groups. The first military personnel arrived in November 1942
