In the early 1940s, the U.S. Navy purchased the grounds for what is now called Smartt Field from Ruth Neubeiser. The Navy constructed an octagonal, 8-runway airfield complete with an outer circular taxiway, hangars and barracks utilized the field as an auxiliary training field during the early years of World War II.

The facility, originally named Neubeiser Field, was renamed as Field #34512 by the Navy and then later renamed again as Smartt Field, in honor of Ensign Joseph Smartt from Robertson, Missouri, who was killed in the Japanese attack on Kaneohe Bay, Hawaii on December 7, 1941.

Federal Government Deeds Ground to Local Governments
In 1957, the federal government deeded the airport grounds, then consisting of 184 acres, to the City of St. Charles and St. Charles County. The city subsequently released their portion of the airport in 1976 to the county.
