text: 1918–1941 During World War I, the U.S. Army acquired  of land in the Miramar Ranch area, on a mesa north of San Diego. Camp Kearny was opened on 18 January 1917 and was named after Stephen W. Kearny, who was commander of the Army of the West during the Mexican–American War. The base was primarily used to train infantrymen on their way to the battlefields of Europe. During World War I, an airstrip was never built on the property, although Army and U.S. Navy aircraft from Naval Air Station North Island did land on the parade deck. Following the Armistice, the base was used to demobilize servicemen and was closed on 20 October 1920. More than 1,200 buildings were demolished when the camp closed.
  Charles Lindbergh's Spirit of St. Louis airplane was built in nearby San Diego. Lindbergh used the abandoned Camp Kearny parade field to practice landings and take-offs before making his historic solo flight across the Atlantic Ocean.
  During the 1930s, the Navy briefly used the air base for helium dirigibles. In 1932, a mooring mast and hangar were built at the camp for the dirigibles, but when the program was abandoned, the base was quiet again.
