5° 58' 60S Long 146° 4' 60E Located
at Gusap in the Ramu Valley at the base of the Finisterre Range. Also known as "Gusap Field" or "Gusap Airdrome".
Built by US Army engineers including the 871st airborne engineer battalion, the base was built around
eight grass runways, with 180 revetments in the complex. Known to the US Army as APO 713 unit 1 (bombers) and unit 2 (fighters).
World War II Pacific Theatre History
Used by American fighters, light bombers and liaison aircraft as a forward airfield during late 1943 until the middle of 1944.
On November 11, 1943 the Australian Army, 6 Machine Gun Battalion (6MGB) was sent Gusap Airfield to protect
the area from any ground attack. They were armed with
.303 Vickers Machine Guns and Bren Guns. On their initial landing
in the C-47s they were nervous as they had been told the airstrip
was only suitable for fighter planes. From day one they were
bombed and strafed. They nicknamed one Japanese pilot "The
Milkman" because he was the bane of their existence there as
be bombed them the same time each morning. It was reported
that he was later shot down near Shaggy
Ridge. The 6MGB were camped about two miles from the aerodrome.
They completed numerous patrols in the nearby Finisterre Ranges to establish the presence of any Japanese. The battalion remained at Gusap until until February 25, 1944.
During 1944-1945, Gusap Airfield was used by the Royal Australian Air Force (RAAF).

Seale of the 871st Airborne Engineer Battalion recalls:
were on the ground the day before the 503rd [Parachute Infantry Regiment PIR] jumped [at Nadzab on September 5, 1943]. We watched
them come down. I remember that the 312th
Bomb Group with A-20's operated out of Gusap. Allot of cripples
landed at Tsilli-Tsilli and later Gusap. They were
wither low on fuel or shot-up and couldn't be sure of getting
Shoot down of a Japanese fighter 41st FS veteran James Hillburn recalls:
was an armor, hanging and fusing bombs and putting in 50 cal
ammo. About mid afternoon a Zero [actually a Ki-61 Tony] approached
field at pattern altitude and slow speed. There was no alert
wind, made a left turn and lined up on strip before an alarm
was sounded. We had a P-47 up with a new engine
getting solo time on it. This pilot was in the right place
to get on
his tail. One short burst and then the Jap tried to leave but
it was too late. I am sure that he was lost and wanting down.
There is no other reason he would have been alone and coming
in so low and slow. It was a sad event that did not have to
fly-by 41st FS veteran James Hillburn recalls:
was in a little field hospital which was located in a beautiful
coconut palm grove. We believed it was property of Palmolive
Peat Co. The palm grove was somewhat higher ground and made
visibility good. Anyway I was in the chow line for breakfast
when 5 fighter planes [Ki-61 Tonys] came over heading for the
airfield. They were not Zeros as they did not have radial engines.
flew by people in the chow line wondered what they were. At
that moment tracers filled the air around the airfield.
The 5 planes went right on through it. AA guns were all around
the field and as I remember each battery had 4 x 50s' on a
platform that turned 360 deg. How they all missed is a miracle.
not know if and damage was done but the 41st received
Disused as an airfield postwar. Postwar, the salvage rights for the area were assigned to Arthur Scott who scrapped most of the wreckage left at the airfield.
Gusap No. 5 (Strip 5) remains in use today for light aircraft. The Gusap area is used as a cattle ranch. Most of the aircraft revetments remain and are clearly visible from the air. Although heavily scrapped, many concrete slabs that were the foundation for buildings remain and other debris from the war.
In 2010, a war monument was built near Gusap for ANZAC Day remembrances. Australian, American and Papuan forces are remembered. Thanks to Greg Kirkpatrick for information.
Eleven US Army bulldozers all lined up along the old airstrip. They
were brought in by gliders to build the airfield.
