Central Field or Iwo Jima Air Base is a World War II airfield on Iwo Jima in the Bonin Islands, located in the Central Pacific. The Bonin Islands are part of Japan. Today, the base is the only airfield on the island, operated by the Japan Self-Defense Forces. ==History== : ''See also: Battle of Iwo Jima'' Located south and west of the midpoint between Tokyo and Saipan, the island of Iwo Jima was needed by the United States Army Air Forces Twentieth Air Force as an emergency landing facility for its B-29 Superfortress strategic bombing campaign against the Empire of Japan. United States Marines landed on Iwo Jima February 19, 1945. The first day saw 2,400 American casualties. During the battle U.S. Marines, sailors and soldiers killed an estimated 20,000 Japanese and captured over 1,000 prisoners. On March 25 the Battle of Iwo Jima was declared over and the island secured, although mopping up continued until July. United States Army units, including the 147th Infantry also participated in the battle. Central Field was one of three Japanese airfields built on Iwo Jima. Reconstruction and expansion work was held up by the protracted land battle, on 16 March it too was operational, with the east-northeast to west-southwest runway graded to 5,200-feet (1,585-meters) and the east-west runway to 4,800-feet (1,463-meters). A second runway parallel to the east-northeast to west-southwest runway was also built; both were built to accommodate B-29s. By 7 July 1945, the first B-29 runway had been paved to 8,500 feet (2,591-meters) and placed in operation. During the day, 102 B-29s, returning from a raid on Japan, landed on the field. Several sub-grade failures occurred in the construction because of ground water and soft spots in the sub-grade. In some places the paving sealed off steam which had been generated below the surface and when the steam condensed, the sub-grade became saturated. By 12 July, the B-29 runway had been completed and paved for a length of 9,800-by-200-feet (2,987-by-61-meters). The parallel runway was eventually lengthened to 9,400-feet (2,865-meters), both with a width of 200-feet (61-meters). The east-west runway built by the Japanese was developed into a fueling strip, 6,000-by-570-feet (1,829-by-174-meters), with 60 fueling outlets. For normal operations, this field could accommodate 120 P-51s and 30 B-24s and 20 B-29s. Central Field was also the headquarters for VII Fighter Command (assigned to Twentieth Air Force) from March 1 – December 1, 1945, along with the intelligence-gathering 41st Photographic Reconnaissance Squadron from August though mid-September 1945. Operational fighter squadrons which performed B-29 escort missions from Central Field were: * 506th Fighter Group, April 24 – December 3, 1945 * 414th Fighter Group, July 7 – December 23, 1945 * 21st Fighter Group, July 16 – December 4, 1945 * 548th Night Fighter Squadron, March 5 – June 12, 1945 * 549th Night Fighter Squadron, (Ground Echelon), March 14, 1945 – February 5, 1946 After the war, the 20th Air Force fighter squadrons moved out to Japan, Okinawa or the Philippines and Central Field came under the Jurisdiction of Military Air Transport Service (MATS), becoming a refueling stop for MATS aircraft in the Western Pacific. It hosted various communications, weather as well as Far East Materiel Command units for supply and maintenance activities. It was under the command of the Iwo Jima Base Command, as a satellite of the 6000th Support Wing, Tachikawa Air Base, Japan. It was likely classified as a remote assignment for military personnel, as other than rudimentary medical and personnel living facilities, no family housing or other quality of life facilities were built to accommodate families for accompanied tours. A third Japanese airfield (Motoyama No. 3) was also reconstructed as "North Field". It required much new construction in rough terrain which consisted principally of consolidated volcanic ash. The initial portion of the work in preparing the sub-grade for the runway entailed the moving of about 200,000-cubic-yards (152,911-cubic-meters) of rock and volcanic ash. Seabee construction was stopped on 27 April and the project was turned over to a USAAF aviation engineer battalion for completion. By V-J day a runway 6,000-feet (1,829-meters) long, had been graded and was paved to 5,500-feet (1,676-meters); 10,000-feet (3,048-meters) of taxiways had been graded; and 129 fighter hardstands provided. 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.〔(AFHRA Document 00462016 6100th Support Wing 1 April-30 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「:''"IWO" redirects here.

For normal operations, this field could accommodate 120 P-51s and 30 B-24s and 20 B-29s.Central Field was also the headquarters for VII Fighter Command (assigned to Twentieth Air Force) from March 1 – December 1, 1945, along with the intelligence-gathering 41st Photographic Reconnaissance Squadron from August though mid-September 1945. Operational fighter squadrons which performed B-29 escort missions from Central Field were:* 506th Fighter Group, April 24 – December 3, 1945* 414th Fighter Group, July 7 – December 23, 1945* 21st Fighter Group, July 16 – December 4, 1945* 548th Night Fighter Squadron, March 5 – June 12, 1945* 549th Night Fighter Squadron, (Ground Echelon), March 14, 1945 – February 5, 1946After the war, the 20th Air Force fighter squadrons moved out to Japan, Okinawa or the Philippines and Central Field came under the Jurisdiction of Military Air Transport Service (MATS), becoming a refueling stop for MATS aircraft in the Western Pacific. It hosted various communications, weather as well as Far East Materiel Command units for supply and maintenance activities. It was under the command of the Iwo Jima Base Command, as a satellite of the 6000th Support Wing, Tachikawa Air Base, Japan. It was likely classified as a remote assignment for military personnel, as other than rudimentary medical and personnel living facilities, no family housing or other quality of life facilities were built to accommodate families for accompanied tours.A third Japanese airfield (Motoyama No. 3) was also reconstructed as "North Field". It required much new construction in rough terrain which consisted principally of consolidated volcanic ash. The initial portion of the work in preparing the sub-grade for the runway entailed the moving of about 200,000-cubic-yards (152,911-cubic-meters) of rock and volcanic ash. Seabee construction was stopped on 27 April and the project was turned over to a USAAF aviation engineer battalion for completion. By V-J day a runway 6,000-feet (1,829-meters) long, had been graded and was paved to 5,500-feet (1,676-meters); 10,000-feet (3,048-meters) of taxiways had been graded; and 129 fighter hardstands provided. 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.(AFHRA Document 00462016 6100th Support Wing 1 April-30 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.」の詳細全文を読む Iwo Jima Air Base''' is a World War II airfield on Iwo Jima in the Bonin Islands, located in the Central Pacific. The Bonin Islands are part of Japan.Today, the base is the only airfield on the island, operated by the Japan Self-Defense Forces.==History==: ''See also: Battle of Iwo Jima''Located south and west of the midpoint between Tokyo and Saipan, the island of Iwo Jima was needed by the United States Army Air Forces Twentieth Air Force as an emergency landing facility for its B-29 Superfortress strategic bombing campaign against the Empire of Japan.United States Marines landed on Iwo Jima February 19, 1945. The first day saw 2,400 American casualties. During the battle U.S. Marines, sailors and soldiers killed an estimated 20,000 Japanese and captured over 1,000 prisoners. On March 25 the Battle of Iwo Jima was declared over and the island secured, although mopping up continued until July. United States Army units, including the 147th Infantry also participated in the battle.Central Field was one of three Japanese airfields built on Iwo Jima. Reconstruction and expansion work was held up by the protracted land battle, on 16 March it too was operational, with the east-northeast to west-southwest runway graded to 5,200-feet (1,585-meters) and the east-west runway to 4,800-feet (1,463-meters). A second runway parallel to the east-northeast to west-southwest runway was also built; both were built to accommodate B-29s. By 7 July 1945, the first B-29 runway had been paved to 8,500 feet (2,591-meters) and placed in operation. During the day, 102 B-29s, returning from a raid on Japan, landed on the field. Several sub-grade failures occurred in the construction because of ground water and soft spots in the sub-grade. In some places the paving sealed off steam which had been generated below the surface and when the steam condensed, the sub-grade became saturated. By 12 July, the B-29 runway had been completed and paved for a length of 9,800-by-200-feet (2,987-by-61-meters). The parallel runway was eventually lengthened to 9,400-feet (2,865-meters), both with a width of 200-feet (61-meters).
