Piva Airfield

Piva Airfield is a former World War II airfield on Bougainville Island in the Solomon Islands archipelago.

World War II
The 3rd Marine Division landed on Bougainville on 1 November 1943 at the start of the Bougainville Campaign, establishing a beachhead around Cape Torokina. Small detachments of the 25th, 53rd, 71st and 75th Naval Construction Battalions landed with the Marines and the 71st Battalion was tasked with establishing a small fighter airfield that would become Torokina Airfield.

On 26 November 1943 the 36th Naval Construction Battalion arrived on Bougainville and on 29 November they started work on a 8000 ft by 30 ft bomber strip. The first plane landed on the bomber strip on 19 December and it was put into operation on 30 December, after several weeks of operation it was extended by an additional 2000 ft. The 71st Battalion built three taxiways with 35 hardstands, a shop area, seven nose hangars, three prefabricated steel huts, and 26 frame buildings. Aviation camps consisted of a 5,000-man camp for Marine Aircraft Group 24. The 77th Battalion arrived on Bougainville on 10 December 1943 and began constructing a fighter airfield parallel to the bomber field. The airfield was completed on 3 January and the first plane landed on 9 January. Several weeks later, the 77th Battalion was instructed to extend the strip by 2000 ft. Both airfields were connected by taxiways and shared fuel tank farms and other facilities. The construction of the airfields frequently took place under Japanese harassing fire such as the Bougainville counterattack, as the US forces never sought to occupy the entire island.

The bomber airfield became known as Piva 1, Piva North Airfield, Piva Uncle Airfield or Piva Bomber Strip while the fighter airfield became known as Piva 2, Piva South Airfield, Piva Yoke Airfield or Piva Fighter Strip. US Navy units based at Piva included:

On 8 March 1944 Japanese artillery opened up on Piva Airfield and destroyed one B-24 Liberator and three fighters and damaged nineteen other aircraft.

By early 1945 base roll-up and salvage operations had commenced and were completed by the end of June 1945.

Postwar
The bomber airfield remains usable as Torokina Airport (IATA: TOK) (not to be confused with Torokina Airfield), while the fighter airfield is completely overgrown with vegetation.
