Harmon Air Force Base is a former World War II United States Army Air Forces airfield, and postwar United States Air Force Base on Guam in the Mariana Islands. Originally named "Depot Field", it was renamed in honor of Lieutenant General Millard F. Harmon. Harmon Air Force Base was closed in 1949 due to budget constraints and was merged with the neighboring Naval Air Station Agana.
