This field could normally accommodate 50 P-51s and 14 B-24s (and eight B-29s in an emergency). North Field was abandoned after the war; its facilities were used for revetments and munitions storage in support of the other two airfields. Central Field stayed in American hands until being turned over to the Japanese Government on 27 June 1968. It then became a navigation and weather station of the Japan Maritime Self-Defense Force (Nihon Kaijo Jieitai), and is still used by the U.S. military as an aircraft refueling depot and as a U.S. Navy special pilot training facility. At any given time about 350 JSDF personnel are posted to Iwo Jima and though the airfield is strictly for military use, commercial flights carrying veterans are frequent visitors.
