On 19 October 1944 the airfield with its 7,000 feet (2,100 m) runway aligned NE/SW together with taxiways and hardstands for 120 aircraft were ready for use.

The 22nd Bombardment Group operating B-24s was based at Angaur from November 1944 until January 1945 when it moved to Guiuan Airfield in the Philippines.

In April 2010 the Palau Senate passed a resolution asking the President to offer Angaur airstrip as a site for the relocation of Marine Corps Air Station Futenma on Okinawa.

The runway improvements give Palau a secondary airfield capable of handling cargo aircraft to back up to Roman Tmetuchl International Airport.

For the 12-month period ending May 23, 1987, the airport had 1,500 air taxi aircraft operations, an average of 125 per month.
