Naval Base Upolu was a naval base built by the United States Navy in 1942 to support the World War II effort. The base was located on Upolu Island, Samoa in the Western Pacific Ocean, part of the Samoan Islands's Naval Base Samoa. After the surprise attack on Naval Station Pearl Harbor on December 7, 1941, the US Navy was in need of setting up more advance bases in the Pacific Ocean. At Naval Base Upolu the Navy built a sea port, an airbase and a seaplane base. [1] [2]

After the World War II's Pacific War war the airstrip was converted to civilian use. Today it is the Faleolo International Airport.

History

Upolu Island, a Polynesia island, is 708 miles east of Fiji, 2,400 miles (3860 km) to the north-east of Sydney, and 2,300 miles (3700 km) south of Hawaii, giving it a key location for both ships and planes to refuel. The US Navy was tasked with building both harbor facilities and an airbase on Upolu. The first to arrive was the 7th Marine Defense Battalion on April 1, 1942. On May 10 the US Navy landed 4th Construction Detachment and work began. The existing pier and seawall were not able to handle the upcoming needs. The Navy build a floating dock with 3-by-7-pontoon barges to begin unloading cargo. Type B ship barges and native scow barges were used also. Existing buildings became temporary warehouses, offices, and a dispensary. Tents were set up for hospital wards, mess hall, and quarters. The base became part of Naval Base Samoa.

The Navy built a 4,000 feet by 200-foot runway on Upolu at Faleolo, an auxiliary field. After removing coconut palms, the runway was paved with crushed and rolled volcanic ash on a lava rock base. The runway was found to be able to support heavy bombers. The runway was operational by July 1942. U.S. Marine Fighting Squadron VMF-111 operated from the Faleolo auxiliary field. In March 1943 the US Navy Seabees lengthened the runway to 6,000 feet and widen it to 350, now the Faleolo International Airport. The Seabees also installed taxiways and parking for 58 planes. Also at the airbase, they built two hangars, quonset hut shops, and quonset hut housing.[ citation needed ]

In May 1942 a seaplane base was built by the Seabees began. Five 30-foot seaplane ramps were built of rock fill and a concrete surface was installed. In the port, six mooring buoys and one nose hangar were built. The seaplane base had storage, a workshop, barracks, and a refueling station. Two anti-aircraft artillery battalions camps were built for protection. US Navy Sea Navy Scout Squadron VS-51 operated out of Naval Base Upolu. VS-51 operated Vought OS2U Kingfisher and Grumman J2F Duck planes under Fleet Air Wing Two. The USS Chandeleur (AV-10), a seaplane tender was stationed at Apia Harbor, to service the planes.[ citation needed ]

Seabees built a 108-bed hospital, operating room, and a dental office at the base. Also added to the base, Seabees built a new 600-by-20-foot wharf with lave rock and concrete road on top. A short distance from the base ammunition storage magazines were built. Construction Seabees depart May 20, 1943, as Construction Battalion Maintenance Unit, CBMU 506. Construction Battalion Maintenance took over the operations of a sawmill and constructed carpenter, plumbing, and sheet-metal shops. CBMU 504 arrived on February 16, 1944, and took over the operations, with CBMU 506 departed on February 27, 1944, for work at Tulagi. The US Navy did beach landing training at Upolu, the SS American Legion and other ships did the training 1943. Closure of the base started in February 1944 and was completed by November 1944, with the base moved to move forward location, closer to the fighting action. [3]

Upolu Island is a tropical forest, that is 75 kilometres (47 miles) long and 1,125 square kilometres (434 square miles). The Island is made from an ancient basaltic shield volcano. Upolu had two ports Apia and Sava, both did not have good natural fleet anchorage. The city of Apia is on the north coast with the small Apia Harbour. [2]

Upolu is an island in Samoa, formed by a massive basaltic shield volcano which rises from the seafloor of the western Pacific Ocean. The island is 75 kilometres long and 1,125 square kilometres in area, making it the second largest of the Samoan Islands by area. With approximately 145,000 inhabitants, it is by far the most populous of the Samoan Islands. Upolu is situated to the southeast of Savai'i, the "big island". Apia, the capital, is in the middle of the north coast, and Faleolo International Airport is at the western end of the island. The island has not had any historically recorded eruptions, although there is evidence of three lava flows, dating back only to between a few hundred and a few thousand years ago.

<span class="mw-page-title-main">US Naval Advance Bases</span> Overseas US Naval Bases

US Naval Advance Bases were built globally by the United States Navy during World War II to support and project U.S. naval operations worldwide. A few were built on Allied soil, but most were captured enemy facilities or completely new. Advance bases provided the fleet with support to keep ships tactically available with repair and supply depots of facilities, rather than return them to the continental United States. Before Japan declared war on the United States the U.S. Navy had a single fleet-sized advanced base in the Territory of Hawaii at Naval Station Pearl Harbor. During the war the U.S. Navy Seabees built over 400 advance bases categorized by size. Naval bases were either Lions or Cubs while airfields were either Oaks or Acorns. Lions and Oaks were major facilities while Cubs and Acorns were minor. PT Boats typically would get a Cub and airfields with single runways were Acorns. The larger bases could do refueling and overhaul; loading of troopship and cargo ships; and preparing amphibious assault ships. Some became major repair depots. The Seabees developed auxiliary floating drydocks were able to repair battle damage and do regular maintenance in the field saving ships trans-pacific trips for repair. A few bases also were developed to be R and R for all U.S. personnel. Most Advance Bases were built by the US Navy's Seabees in Naval Construction Battalions (CBs). At the start of the war civilian contractors were employed in construction. The Seabees in World War II built most of the airfields used by the United States Army Air Forces and United States Marine Corps, as they had the ships and cranes needed to transport the vast amount of equipment needed at the advance bases. The US Army and United States Coast Guard also operated out of many of these facilities. Seabees could build new or repair damaged runways, and with advancements in heavy bomber technology lengthen runways as needed. A few Naval Advance Bases were built for the Korean War and Vietnam War.
