During early 1942, the Australian Civil Construction Corps built two surfaced crossed runways, completed in a record six weeks while working day and night to complete the runways. On March 25, 1942 the first aircraft to land on the new runway was an A-24 Dive Bomber from the 3rd Bombardment Group (3rd BG).

During World War II, Charters Towers was also the location of RAAF No.9 Inland Aircraft Fuel Depot (IAFD), completed in 1942 and closed on 29 August 1944. Usually consisting of 4 tanks, 31 fuel depots were built across Australia for the storage and supply of aircraft fuel for the RAAF and the US Army Air Forces.
Beginning in June 1943, Charters Towers was also the location for a major USAAF chemical bomb depot operated by the 760th Chemical Depot Company (Aviation). The depot contained bombs filled with mustard agent, cyanogen chloride and other toxic chemicals. In addition to maintaining the depot, the 760th cooperated with the Australian Chemical Warfare Research Unit to conduct research on bomb design and delivery techniques. Late in 1944, the depot and its contents were moved to Oro Bay, New Guinea.
