This airport is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a general aviation facility.HistoryLerdo Field, as the airport was initially known during World War II was first opened in June 1941 when the United States Army Air Corps (USAAC) dispatched a small garrison of airmen to open an airfield at Shafter.The name was derived from close proximity to the highway of the same name. The airfield commander utilized Bakersfield College as his headquarters, while airmen were quartered in temporary facilities from Bakersfield to Wasco while barracks and other structures were being built. As construction proceeded though the rest of the year, the Minter Sub-Depot was established as a branch of the Sacramento Air Depot.
