Tinian, with its sister islands of the Marianas, had passed through Spanish and German hands prior to becoming a protectorate of Japan following World War I. Under Japanese administration, Tinian was largely a sugar plantation. The island had two good airfields with a third under construction by the Japanese in 1944. West Field originated as the Japanese Gurguan Point Airfield, having two parallel runways.

West Field is a former World War II airfield on Tinian in the Mariana Islands. Today, West Field is used as the civilian Tinian International Airport. West Field at Tinian Naval Base was a base for Twentieth Air Force B-29 Superfortress operations against the Japanese Home Islands in 1944–45 and the base for the B-29 Superfortress 58th Bombardment Wing.

The airport covers an area of 1,416 acres which contains one paved runway (8/26) measuring 8,600 x 150 feet.
