US Naval Base Carolines included a number of United States Navy bases on the Caroline Islands in the western Pacific Ocean, to the north of New Guinea during World War II. The bases were built to support the island hopping Pacific War efforts of the allied nations fighting the Empire of Japan. [1]
The Caroline Islands is now the Federated States of Micronesia nation. Micronesia comprises Kosrae State, Pohnpei State, Chuuk State (in past spelled Truk) and Yap State. After the Spanish–American War in 1898, the islands became a German colony and German naval base. At the start of World War I in 1914 British warships destroyed the German colonial plantation owner's radio station. On October 7, 1914, Japan invaded and took over Yap island without a battle. Japan and Britain made a treaty giving Japan the Pacific islands north of the Equator, signed at the Treaty of Versailles in 1919. In the 1930s Japan built naval and airbases on many of the islands. Truk Lagoon was the largest and strongest of these bases. The United States Army Air Forces bombed the Truk base, but it was bypassed in the amphibious landing war. Japan's Truk base had five airfields, fleet anchorage, a few seaplane bases, torpedo boat bases, repair facilities, and later a radar station. Japan also built a large base at Ponape, now Pohnpei. By February 1944, the US bombers destroyed Truk and by sea, the US Navy cut had cut off Truk and the 5,000 Japanese troops. The US also bypassed Ponape in the Senyavin Islands and it 8,000 troops. [2]
The United States Armed Forces built a large base at Ulithi Atoll in the Yap islands, as it had a large fleet anchorage for up to 700 ships. The US Army 81st Division landed unopposed on Ulithi on September 23, 1944. Soon US Navy Seabees started work building the large base at Ulithi. The US Navy survey ship USS Sumner found the lagoon was well protected and usable for fleet anchorage. Japan bombed the US base at Ulithi a few times, with only marginal damage. The Fleet Post Office (FPO) for Caroline Islands was # 3249. [3]
After the war, the Caroline Islands became parts of the Trust Territory of the Pacific Islands administered by the United States. In 1986, the new nation of the Federated States of Micronesia was formed. Independence was proclaimed on May 10, 1979, and Compact of Free Association was established on November 3, 1986. [4]
From the US Naval Base Carolines the US had many missions against Japan bases in the Carolines. Japan's base at Truk, that the US Navy called The "Gibraltar of the Pacific, was invasion bypassed in the island hopping Pacific war efforts. Truk had over 30,000 troops, seaport, five airstrips, a seaplane bases, a torpedo boat station, a submarine base and coastal artillery. Truk was attacked by air and had its supply lines cut off by sea, called Operation Hailstone. [18] [19]
Ulithi is an atoll in the Caroline Islands of the western Pacific Ocean, about 191 km (103 nmi) east of Yap, within Yap State.
Chuuk Lagoon, previously Truk Atoll, is an atoll in the central Pacific. It lies about 1,800 kilometres northeast of New Guinea and is part of Chuuk State within the Federated States of Micronesia (FSM). A protective reef, 225 kilometres (140 mi) around, encloses a natural harbour 79 by 50 km, with an area of 2,130 km2 (820 sq mi). It has a land area of 93.07 square kilometres, with a population of 36,158 people and a maximal elevation of 443 metres (1,453 ft). Weno city on Weno Island functions as both the atoll's capital and the state capital, and is the largest city in the FSM with its 13,700 people.
Operation Hailstone was a massive United States Navy air and surface attack on Truk Lagoon on 17–18 February 1944, conducted as part of the American offensive drive against the Imperial Japanese Navy in the Pacific Ocean theatre.
Operation Inmate was an attack by the British Pacific Fleet against Japanese positions on Truk Atoll in the central Pacific Ocean during the Second World War. The attacks against the isolated islands on 14 and 15 June 1945 were conducted to provide combat experience for the aircraft carrier HMS Implacable and several of the fleet's cruisers and destroyers ahead of their involvement in more demanding operations off the Japanese home islands.
Chuuk International Airport is an airport located on Weno, the main island of the State of Chuuk in the Federated States of Micronesia.
Naval Base Ulithi was a major United States Navy base at the Ulithi Atoll in the Caroline Islands in the western Pacific Ocean, to the north of New Guinea during World War II. The base was built to support the island-hopping Pacific War efforts of the Allied nations fighting the Empire of Japan. In terms of the number of ships at one base, Naval Base Ulithi was the largest naval base in the world in 1944 and 1945, with over 600 ships at times.
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 provide 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.
Peleliu Naval Base was a major United States Navy sea and airbase base on Peleliu island, one of sixteen states of Palau. The United States Marine Corps took the island in the Battle of Peleliu during World War II. Battle of Peleliu was a costly conflict that started September 15, 1944, and ended November 27, 1944. On September 30, 1944, Peleliu is declared occupied. The taking of Peleliu and Morotai gave the sea and air protection needed for the later invasion of the Philippines. US Navy Seabee built a number of facilities at Peleliu Naval Base.
Naval Base Milne Bay, also called Naval Advance Base Milne Bay, was new major United States Navy sea and airbase base built on Milne Bay in Milne Bay Province in south-eastern Papua New Guinea. By spring 1943, the build up of the US Navy to support the Pacific War had caused overcrowding at the ports on the east coast of Australia. To help, Seabees departed Naval Base Brisbane on June 19, 1943 to set up a new base in Milne Bay. Naval Base Milne Bay headquarters was at Ladava Navy Base. The Royal Australian Navy already had a small base in Milne Bay: HMAS Ladava. Australians were able to defend and keep Milne Bay in the Battle of Milne Bay in 1942. Naval Base Milne Bay was built during World War II to support the many ships and aircraft fighting and patrolling in the South West Pacific theatre of war. Ladava Navy Base provided a large protective US Navy fleet anchorage at Gahora Bay next to Ladava. At Naval Base Milne Bay, Seabees built a large Naval facility.
Naval Base Manila, Naval Air Base Manila was a major United States Navy base south of the City of Manila, on Luzon Island in the Philippines. Some of the bases dates back to 1898, the end of the Spanish–American War. Starting in 1938 civilian contractors were used to build new facilities in Manila to prepare for World War II. Work stopped on December 23, 1941, when Manila was declared not defendable against the Empire of Japan southward advance, which took over the city on January 2, 1942, after the US declared it an open city. US Navy construction and repair started in March 1945 with the taking of Manila in the costly Battle of Manila ending on March 2, 1945. Naval Base Manila supported the Pacific War and remained a major US Naval Advance Base until its closure in 1971.
Naval Base Brisbane was a major United States Navy base built in the early part of World War II at Brisbane, Queensland, Australia. At first, operated as a base for patrol aircraft and convoy escort aircraft to protect the last leg of the Pacific War to the Southwest Pacific. As the US Navy expanded in the island hopping campaign, Naval Base Brisbane expanded to include a submarine base, repair depot, seaplane base and other facilities. US Navy operations started on April 14, 1942, and ended after the war in 1945.
Naval Base Tarawa was a naval base built by the United States Navy in 1943 to support the World War II effort. The base was located on Tarawa atoll in the Gilbert Islands in the Central Pacific Ocean. The base was built as one of many advance bases in the island-hopping campaign towards the Empire of Japan. At Naval Base Tarawa the Navy built a seaport, seaplane base and two airbases. Construction started after the Battle of Tarawa ended November 23, 1943, part of Operation Galvanic.
Naval Base Fiji was a naval base built by the United States Navy in 1942 to support the World War II effort. The base was located on Fiji in the Central Pacific Ocean. The base was built as one of many advance bases in the island-hopping campaign towards the Empire of Japan. The US Navy built seaports, seaplane bases and airfields used for staging in the Pacific War.
Naval Base Gilbert Islands were naval bases built by the United States Navy in 1943 to support the World War II effort. The bases were located on in the Gilbert Islands in the Central Pacific Ocean. The bases were built as part of the many advance bases in the island-hopping campaign towards the Empire of Japan. The largest base was the Naval Base Tarawa. At Tarawa the Navy built a seaport, supply depots, a small ship repair depot, Carrier Aircraft Service Unit, seaplane base and two airbases. Construction started after the Battle of Tarawa ended on November 23, 1943, part of Operation Galvanic. The bases were built by the US Navy's Seabees, Naval Construction Battalions. After the war the bases were abandoned. Some of the airfields became civilian airports.
Naval Base Kwajalein was United States Navy base built on Kwajalein Atoll, in the Marshall Islands to support the World War II efforts in the Pacific War. The base was built after the Battle of Kwajalein ended 3 February 1944. The US Navy built airfields, a seaport and a craft repair depot on the captured islands. The base was part of the vast Naval Base Marshall Islands.
Naval Base Majuro was a major United States Navy base built on Majuro Atoll, in the Marshall Islands to support the World War II efforts in the Pacific War. The base was built after the Battle of Majuro-Kwajalein ended 3 February 1944. Majuro was found to be unoccupied and abandoned when the United States Army arrived. The US Navy built airfields, a seaport, and other facilities on the captured islands. The base was part of the vast Naval Base Marshall Islands.
Naval Base Marshall Islands were United States Navy advance bases built on the Marshall Islands during World War II to support the Pacific War efforts. The bases were built by US Navy after the Marshall Islands campaign that captured the islands from the Empire of Japan. By February 1944 the United States Armed Forces had captured the islands. Most of the airfields and other facilities Japan had built were destroyed in allied bombing raids and naval bombardment. US Navy Seabee Construction Battalions arrived as soon as the area was secured and remove the debris. The Seabees quickly repaired, built and improved the airfield/runways and seaport. Seabees often worked around the clock to get airfields operational so that fighter aircraft and bombers could start operating. The bases were used for staging upcoming campaigns and for repair.
US Naval Base Solomons was a number of United States Navy bases in the Solomon Islands in the Pacific Ocean. Most were built by the US Navy Seabees, Naval Construction Battalions, during World War II as part of the Pacific War. In August 1942 the United States Armed Forces took the Guadalcanal in the Solomon, in the Battle of Guadalcanal. US Navy Seabees built a new base at Guadalcanal, Naval Base Guadalcanal and then on other islands in the Solomons.
Naval Base Eniwetok was a major United States Navy base located at Enewetak Atoll in the Marshall Islands, during World War II. The base was built to support the island-hopping strategy used by allied nations fighting the Empire of Japan in the Pacific War. During 1944-5 Eniwetok was one of the busiest naval bases in the world with over 488 ships.
