Role in World War II

Isley Field, Saipan, 1945

Today's Saipan International Airport was a prewar airfield on Saipan that was originally constructed by the Japanese in 1934 and named Aslito Field. During World War II, the Imperial Japanese Navy Air Service (IJNAS) assigned two squadrons of Mitsubishi A6MT Zeros to the airfield in mid-June 1944. These squadrons took part in their defense of the Mariana Islands during the Battle of the Philippine Sea later that month, being almost wiped out by the American forces during the battle.

The airfield was seized by the United States Army 27th Infantry Division on the night on June 16-17, 1944 during the Battle of Saipan. During the battle, a Zero from Guam actually landed at Aslito Airfield, the pilot being unaware that the field had fallen to the Americans. As it landed it was fired upon and it crashed at the end of the runway. The pilot survived and the plane was captured. The field was renamed Isley Field after United States Navy Commander Robert H. Isley who was killed on June 13, 1944 while strafing the base.

Once in American hands, Isley Field was expanded considerably to support Twentieth Air Force B-29 Superfortress operations. The XXI Bomber Command had been assigned the overall responsibility of the B-29 operations out of the Marianas bases, and Isley Field was to be used by the 73rd Bombardment Wing (which consisted of the 497th, 498th, 499th, and 500th Bombardment Groups).

The first B-29 arrived on Saipan on October 12, 1944, and by November 22, over 100 B-29s were at Isley. The XXI Bomber Command was assigned the task of destroying the aircraft industry of Japan in a series of high-altitude, daylight precision attacks.

After several months of disappointing high level bombing attacks from Isley (and the other Twentieth Air Force airfields on Guam and Tinian), General Curtiss LeMay, Commander of Twentieth Air Force issued a new directive that the high-altitude, daylight attacks be phased out and replaced by low-altitude, high-intensity incendiary raids at nighttime, being followed up with high explosive bombs once the targets were set ablaze. These nighttime attacks on Japan proved devastatingly effective, and the superfortress missions from Isley Field led to massive destruction of industrial targets in Japan, with large industrial areas of Tokyo, Nagoya, and Osaka being repeatedly attacked by waves of American bombers flying from the Marianas until the war's end.

With the end of the war the wing's four bomb groups were all returned to the United States, with their B-29s either being flown to Clark Air Base in the Philippines for scrapping, or were flown to storage facilities in Texas or Arizona. The 73d Bomb Wing was reassigned to the United States in December 1945. The airfield was returned to civil control and it reverted back to being called Aslito Field.
