History

The City of Duluth purchased the original property for the airport in 1929 from St. Louis County. The airport was constructed on 640 acres (2.6 km²) of land with two 2650 feet (807.7 m) sod runways. Subsequently, in 1930, the airfield was dedicated as a public airport. The airport was called the Williamson-Johnson Municipal Airport until 1963 at which time it was renamed Duluth International Airport. Note: The U.S. Air Force occupied the largest portion of the airport (designating its area "Duluth Air Force Base") until its mission termination in in the 80's.

The Air Force provided Fire Fighting services for the entire airport as well as runway extensions and runway improvements to allow for larger and faster aircraft. The civillian terminal was built on the southeastern corner of the Air Force Base, below the National Guard Facilities.

 (SAGE) Data Center (DC-10) was established at Duluth under the 37th AD. The SAGE system was a network linking Air Force (and later FAA) General Surveillance Radar stations into a centralized center for Air Defense, intended to provide early warning and response for a Soviet nuclear attack . Both the DuADS and the DC-10 SAGE center were placed under the 30th Air Division. DC-10 became operational on 15 November.

In 1960, ADC deployed CIM-10 Bomarc surface-to-air missiles to Duluth. The Bomarc was the only surface-to-air missile ever deployed by the United States Air Force. All other U.S. land-based SAMs were and are under the control of the United States Army. The Bomarc site was located 10 miles NE of the station at 46°55′56"N 091°53′00"W, and was manned by the 74th Air Defense Missile Squadron. The 74th ADMS was activated on 1 April 1960, putting 28 IM-99B Bomarcs on operational status, being networked into the SAGE DC-10 and equipped with W40
