Occupied by the Japanese until the official surrender of Japan on September 2, 1945.

The wreckage of several Japanese aircraft damaged during air raids remained to the side of the runway. The ground in this area was at one time littered with airfield debris: spare parts, rusted guns and ammunition.

Don Baer visited in 1976:
"I was on Yap in 1976. At the time there were two Zeros to the side of the runway. They were in fair condition then."
