1° 0' 0S Long 136° 0' 0E Biak Island is the located in the Schouten Island Group (Schouten Archipelago) in Papua Province in Indonesia.
Borders Geelvink Bay (Cenderawasih Bay) and Yapen Strait (Japen Strait) to the south and the northern coast of western New Guinea.
During 1942, occupied by the Japanese Army who constructed three runways on the south coast: Mokmer Drome, Sorido Drome and Borokoe Airfield. During early 1944, the Japanese began strengthening their defensive positions on Biak in anticipation of an American landing at this location.
In late April 1944 after the U. S. Army occupation of the Hollandia area, engineers discovered the soil in the area was too soft for heavy bomber operations and Biak Island was targeted for the coral surfaced runways and deemed better for U. S. Army Air Force (USAAF) operations. Starting in late April 1944, Biak was targeted by American bombers and fighters.
American and Japanese missions against Biak
April 28, 1944–July 9, 1944
On May 27, 1944 the U. S. Army 41st Infantry Division "Jungleers" made an amphibious landing on the southern coast of Biak at Bosnik. A tank versus tank
battle occurred on Biak, when Japanese Type 95 Ha Go tanks
attempted to attack the beachhead. They were destroyed by M4 Sherman tanks. Defending from natural limestone caves including Japanese Cave (Goa Jepang), the Japanese Army were able to attack American forces and delayed their use of Mokmer
Afterwards, the Japanese attempted to land reinforcements elsewhere on Biak to bolster the defense. In total, estimated casualties on Biak were 435 Americans KIA and
2,360 WIA. The
Japanese lost an estimated 6,125 KIA with 460 POWs, and
360 Formosan POWs.
After securing the island, the U. S. Army
designated Biak Island "Base H (Biak)" and developed the southern portion of the island with airfields and base areas. Biak became U. S. Army Post Office 920 (APO 920). Biak Island supported offensive operations in the rest of Dutch New Guinea and late the liberation of the southern Philippines.

Biak Island has a large Indonesian naval base and the island has
better infrastructure than in most other places in the
province. During the 1980-1990s, Biak was developed as a tourist destination when international flights landed at Mokmer Drome to refuel. Today, many parts of the island are
off limits to visitors.
