Central Field or Iwo Jima Air Base( IATA : IWO, ICAO : RJAW) is a former 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.
The Japanese had constructed the airfield near the center of island laid out as an "X" of two intersecting runways one 5,225 feet (1,593 m) and the other 4,425 feet (1,349 m). [1] : 370
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 as an emergency landing site for its B-29 Superfortress strategic bombing campaign against the Empire of Japan. The purpose of the assault was to take the island for the three Japanese airfields so that the U.S. Navy Seabees could turn them in to United States facilities. Prior to the assault NCB 133 was assigned to get the southern Motoyama #1 airfield operational and NCB 31 was assigned the central Motoyama #2. On D-plus 5 that was changed because of the casualties the 133rd had taken and the 31st CB was assigned to Motoyama #1. [2] On D-plus 6 the assignments were changed again. The 62nd CB attached to the reserve in V Amphibious Corps was given Motoyama #1, the 31st CB was given Motoyama #2 and the 133rd was given the barely started Motoyama #3. However, the Seabees and elements of the 2nd Separate Engineer Battalion worked together until the Marine ground forces had taken possession of their respective airfield construction assignments. [2] [3]
Reconstruction and expansion work was held up by the protracted land battle, on 16 March the airfield, named Central Field, became operational, with the east-northeast to west-southwest runway graded to 5,200 feet (1,600 m) and the east–west runway to 4,800 feet (1,500 m). 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 (2,600 m) 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 feet (3,000 m) by 200 feet (61 m). The parallel runway was eventually lengthened to 9,400 feet (2,900 m), both with a width of 200 feet (61 m). [1] : 371–2 The east–west runway was developed into a fueling strip, 6,000 feet (1,800 m) by 570 feet (170 m), with 60 fueling outlets. [4] : 596 For normal operations, this field could accommodate 120 P-51 Mustangs, 30 B-24 Liberators and 20 B-29s.[ citation needed ]
Central Field was headquarters for VII Fighter Command of the Twentieth Air Force from March 1 – December 1, 1945, [5] : 445 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:
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.[ citation needed ]
The third incomplete Japanese airfield (Motoyama No. 3) 24°47′37″N141°19′29″E / 24.79361°N 141.32472°E was built as the "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.[ citation needed ] By V-J Day a runway 6,000 feet (1,800 m) long, had been graded and was paved to 5,500 feet (1,700 m); 10,000 feet (3,000 meters) of taxiways had been graded; and 129 fighter hardstands provided. [1] : 372 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.[ citation needed ]
Central Field stayed in American hands until being turned over to the Japanese Government on 27 June 1968. [6] 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.[ citation needed ]
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.[ citation needed ]
Of the three WWII airfields, Central Field is the only one that remains in use today. [7]
The Battle of Iwo Jima was a major battle in which the United States Marine Corps (USMC) and United States Navy (USN) landed on and eventually captured the island of Iwo Jima from the Imperial Japanese Army (IJA) during World War II. The American invasion, designated Operation Detachment, had the purpose of capturing the island with its two airfields: South Field and Central Field.
1st Battalion, 23rd Marines (1/23) is one of 32 infantry battalions in the United States Marine Corps, and one of only eight battalions found in the reserve. It is located throughout Texas and Louisiana consisting of approximately 1000 Marines and Sailors. They fall under the command of the 23rd Marine Regiment and the 4th Marine Division.
When World War II broke out the United States Naval Construction Battalions (Seabees) did not exist. The logistics of a two theater war were daunting to conceive. Rear Admiral Moreell completely understood the issues. What needed to be done was build staging bases to take the war to the enemy, across both oceans, and create the construction force to do the work. Naval Construction Battalions were first conceived at Bureau of Yards and Docks (BuDocks) in the 1930s. The onset of hostilities clarified to Radm. Moreell the need for developing advance bases to project American power. The solution: tap the vast pool of skilled labor in the U.S. Put it in uniform to build anything, anywhere under any conditions and get the Marine Corps to train it. The first volunteers came skilled. To obtain these tradesmen, military age was waived to age 50. It was later found that several past 60 had managed to get in. Men were given advanced rank/pay based upon experience making the Seabees the highest paid group in the U.S. military. The first 60 battalions had an average age of 37.
In anticipation of the Battle of Iwo Jima, Lieutenant General Tadamichi Kuribayashi prepared a defense that broke with Japanese military doctrine. Rather than defending the beaches, Kuribayashi devised a defense that maximized enemy attrition. The American plan of attack was made in anticipation of a standard defense.

It was redesignated the 20th Fighter Wing and later, the 46th Fighter Wing before inactivating on 24 August 1948.
The XXI Bomber Command was a unit of the Twentieth Air Force in the Mariana Islands for strategic bombing during World War II.
The 548th Combat Training Squadron is a United States Air Force squadron assigned to the 57th Operations Group at Fort Johnson, Louisiana. It is geographically separated from the 57th, whose headquarters are at Nellis Air Force Base, Nevada. At Fort Johnson, the squadron controls multi-service close air support and forward air control aircraft and tactical air control assets in combat exercises with the US Army Joint Readiness Training Center.
The 549th Combat Training Squadron is a non-flying United States Air Force unit. It is assigned to the 57th Operations Group, and is stationed at Nellis Air Force Base, Nevada. It conducts air support and air interdiction sorties in "Green Flag (West)" exercises to train USAF fighter pilots and the aerospace power component to the US Army's brigade combat training.
South Field was a World War II airfield on Iwo Jima in the Volcano Islands, located in the Central Pacific. The Volcano Islands are part of Japan. The airfield was located on the southern corner of Iwo Jima located on the Motoyama plateau, to the north of Mount Suribachi. South Field was significant to the overall Battle of Iwo Jima.
East Field is a former World War II airfield on Saipan in the Mariana Islands, part of Naval Advance Base Saipan.
North Field was a World War II airfield on Tinian in the Mariana Islands. Abandoned after the war, today North Field is a tourist attraction. Along with several adjacent beaches on which U.S. Marines landed during the Battle of Tinian, the airfield is the major component of the National Historic Landmark District Tinian Landing Beaches, Ushi Point Field, Tinian Island.
During World War II, a series of Japanese air attacks on the Mariana Islands took place between November 1944 and January 1945. These raids targeted United States Army Air Forces (USAAF) bases and sought to disrupt the bombing of Japan by Boeing B-29 Superfortress heavy bombers operating from the islands. The Japanese lost 37 aircraft during this operation, but destroyed 11 B-29s and damaged a further 43. Preparations were also made for commando raids on the bases in early and mid-1945 but these did not go ahead.
Nanumea Airfield is a former World War II airfield on the island of Nanumea in the Ellice Islands.
Naval Base Saipan or Naval Advance Base Saipan or Naval Air Base Saipan was a United States Navy Naval base built during World War II to support Pacific Ocean theater of war and the many warships and troops fighting the war. The base was on the island of Saipan in the Northern Mariana Islands. The base was part of the Pacific island hopping campaign. The base construction started after the Battle of Saipan ended on July 9, 1944. US Naval Advance Base Saipan was constructed by the Seabees Naval Mobile Construction Battalions. The base was under the Commander Naval Forces Marianas. Saipan is 12 miles (19 km) long and 5 miles (8.0 km) wide. About 70% of the island was sugarcane cultivation at the start of the base construction. At the start of the Battle of Saipan, the island's population had about 30,000 Japanese troops and about 20,000 Japanese civilians. The city of Garapan was the administrative center for the Saipan governmental district.
Tinian Naval Advanced Base was a major United States Navy sea and air base on Tinian Island, part of the Northern Mariana Islands on the east side of the Philippine Sea in the Pacific Ocean. The base was built during World War II to support bombers and patrol aircraft in the Pacific War. The main port was built at the city and port of San Jose, also called Tinian Harbor. All construction was carried out by the Navy's Seabees 6th Naval Construction Brigade, including the main two airfields: West Field and North FieldUnited States Army Air Forces's long-range Boeing B-29 Superfortress bombers. The Navy disestablished the Tinian Naval Advanced Base on 1 December 1946.
Peleliu Naval Base was a major United States Navy sea and airbase base on Peleliu island, one of sixteen states of Palau. The United States Marine Corps took the island in the Battle of Peleliu during World War II. Battle of Peleliu was a costly conflict that started September 15, 1944, and ended November 27, 1944. On September 30, 1944, Peleliu is declared occupied. The taking of Peleliu and Morotai gave the sea and air protection needed for the later invasion of the Philippines. US Navy Seabee built a number of facilities at Peleliu Naval Base.
Naval Base Iwo Jima was a naval base built by United States Navy on the Japanese Volcano Island of Iwo Jima during and after the Battle of Iwo Jima, that started on February 19, 1945. The naval base was built to support the landings on Iwo Jima; the troops fighting on Iwo Jima; and the repair and expansion of the airfields on Iwo Jima. United States Navy Seabee built all the facilities on the island.
Naval Base Okinawa, now Naval Facility Okinawa, is a number of bases built after the Battle of Okinawa by United States Navy on Okinawa Island, Japan. The naval bases were built to support the landings on Okinawa on April 1, 1945, and the troops fighting on Okinawa. The Navy repaired and did expansion of the airfields on Okinawa. United States Navy Seabees built or repaired the facilities on the island. The bases on Okinawa put the United States Armed Forces only 350 miles from Japan's home islands. Most facilities closed after the war, but some are still in use today by all branches of the United States Armed Forces.
