The Fairmont Army Airfield, with its well maintained hangars, support buildings, and commander's house, was the best remaining example, as a collection of buildings, of the Army Airfields in the State of Nebraska. Due to the rural location, unencumbered by surrounding development, and the good condition of the remaining buildings, particularly the hangars, the Fairmont Army Airfield was placed on the National Register of Historic Places as an historic district. The District includes the hardstands, aprons and existing runways, all remaining buildings, extending to the edges of the roads where buildings remain. This encompasses historic landscape features such as roads and World War II-era planted trees.
