Location
Located at the northern most tip of Cape Glochester.

Construction
Construction of an airfield was begun by the Australians, finished by the Japanese and improved by the Americans after they occupied the area.

Japanese Occupation
The airfield had two separate strips, defended by 12 heavy and 34 light anti-aircraft batteries, including fake positions (as of October 19, 1943). The airfield was so heavily bombed by the 5th AF, a new term entered the military vocabulary 'to Gloucesterize' a target, from the pot-marked appearance of the airfield from aerial photos.

American Missions Against Cape Gloucester
December 23, 1942 - January 29, 1944

Assault on the Airfield
Col. Kouki Sumiya of the 53rd Infantry had fallen back to the airfield on December 29th to defend the 'Razorback Hill' from bunkers on this ridge that spans across the south-west approaches to the airfield. The 5th Marines, 1st & 2nd Battalions attacked the area on December 30 supported by tanks and artillery. Overpowered, the position was defeated by dusk. The following day, General Rupertus had the US flag raise next to the wreckage of a Betty bomber on Airfield No. 2.

American Use
After Marines captured the strip on December 30, 1943, heavy rains delayed its improvements, and American aircraft did not start operating from the strip until February 1944. At the airfield, they captured the intact Ki-61 263, and sent it to Australia for technical evaluation. The other wrecks were evaluated by ATIU (Air Technical Intelligence Unit) at the strip.

Robert Rocker adds:
"The 36th FS and 80th FS were based at Glocester in March of 1944, but it was raining so much in April they pulled both squadrons back into New Guinea. Bill Wallisch a 35th FS Crew Chief told me the mud was so bad there that they just could not operate properly."

Gloucester Airfields

 

Cape Gloucester I (Old Strip, West Airfield)
This was the pre-war runway first constructed by Australians at Cape Glouchester. This single 3,900' runway extended north to south closest to the sea. A series of Japanese built revetments were located along the eastern edge of the strip. Largely abandoned by the Japanese, it was overgrown when captured by Marines.  Reportedly, this strip was later repaired and used until 1990s, when it was deemed unsafe.

Today
Postwar remained in use for civilian aircraft to service the Cape Gloucester area.  It is not used by larger commercial flights. Volcano eruption nearby temporarily closed the strip.

Brian Bennett adds:
"I found the old dump at Cape Gloucester some years ago but you would need to move a bit of dirt to get at it. I recall that there were bits of Japanese aircraft sticking out of the ground."
