Atoll in the Federated States of Micronesia

Chuuk Lagoon, previously Truk Atoll, is an atoll in the central Pacific. It lies about northeast of New Guinea and is part of Chuuk State within the Federated States of Micronesia (FSM). A protective reef, around, encloses a natural harbour , with an area of It has a land area of , with a population of 36,158 people and a maximal elevation of Weno city on Weno (formerly Moen) 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. Chuuk Lagoon was the Empire of Japan's main naval base in the South Pacific theatre during World War II. It was the site of a major U. S. attack during Operation Hailstone in February 1944, and Operation Inmate, a small assault conducted by British and Canadian forces during June 1945.

Chuuk means mountain in the Chuukese language. The lagoon was known mainly as Truk (a mispronunciation of Ruk), until 1990. Other names included Hogoleu, Torres, Ugulat, and Lugulus.

Chuuk Lagoon is part of the larger Caroline Islands group. The area consists of eleven major islands (corresponding to the eleven municipalities of Truk lagoon, which are Tol, Udot, Fala Beguets, Romanum, and Eot of Faichuk group, and Weno, Fefen, Dublon, Uman, Param, and Tsis of Nomoneas group) and 46 smaller ones within the lagoon, plus 41 on the fringing coral reef, and is known today as the Chuuk islands, part of the Federated States of Micronesia in the Pacific Ocean.

It is not known when the islands of Chuuk were first settled, but archaeological evidence indicates that islands of Feefen and Wééné had human settlements in the first and second century BC. Later evidence indicates that widespread human settlements appeared in Chuuk during the 14th century AD.

The first recorded sighting by Europeans was made by Spanish navigator Álvaro de Saavedra on board the ship Florida during August or September 1528. They were later visited by Spaniard Alonso de Arellano on 15 January 1565 on board of galleon patache San Lucas. As part of the Caroline Islands, Truk was claimed by the Spanish Empire, which made an effort to control the islands in the late 19th century. Chuuk Lagoon was inhabited by several tribes that engaged in intermittent warfare, as well as a small population of foreign traders and missionaries. Spanish control over the islands was nominal. The Spaniards stopped to raise a flag over Chuuk in 1886 and returned in 1895 as part of an attempt to assert control and negotiate peace between warring Chuukese tribes. No permanent Spanish settlement was established, and tribal violence continued until the German colonial era. The Caroline Islands were sold to the German Empire in 1899, after Spain withdrew from the Pacific in the aftermath of the Spanish–American War. During the First World War, The Japanese Navy was tasked with pursuing and destroying the German East Asia Squadron and protection of the shipping lanes for Allied commerce in the Pacific and Indian Oceans. During the course of this operation, the Japanese Navy seized the German possessions in the Marianas, Carolines, Marshall Islands and Palau groups by October 1914. Chuuk then became a possession of the Empire of Japan under the South Seas Mandate following Germany's defeat.

Naval Base Truk in the Truk Lagoon was the Empire of Japan's main base in the South Pacific theatre of World War II. Truk was a heavily fortified base for Japanese operations against Allied forces in New Guinea and the Solomon Islands, serving as the forward anchorage for the Imperial Japanese Navy (IJN). Truk Lagoon was considered the most formidable of all Japanese strongholds in the Pacific. On the various islands, the Japanese Civil Engineering Department and Naval Construction Department had built roads, trenches, bunkers and caves. Five airstrips, seaplane bases, a torpedo boat station, submarine repair shops, a communications center and a radar station were constructed during the war. Protecting these various facilities were coastal defense guns and mortar emplacements. Because of its heavy fortifications, both natural and manmade, the base at Truk was known to Allied forces as "the Gibraltar of the Pacific". Some have described Truk as Japan's equivalent of the Americans' Pearl Harbor. In 1944, Truk's capacity as a naval base was destroyed through naval air attack in Operation Hailstone. Forewarned by intelligence a week before the US raid, the Japanese had withdrawn their larger warships (heavy cruisers and aircraft carriers) to Palau. Once the American forces captured the Marshall Islands, they used them as a base from which to launch an early morning attack on 17 February 1944 against Truk Lagoon. Operation Hailstone lasted for three days, as American carrier based planes sank 12 smaller Japanese warships (light cruisers, destroyers, and auxiliaries) and 32 merchant ships, while destroying 275 aircraft, mainly on the ground. The consequences of the attack made "Truk lagoon the biggest graveyard of ships in the world". The attacks for the most part ended Truk as a major threat to Allied operations in the central Pacific. The Japanese garrison on Eniwetok was denied any realistic hope of reinforcement and support during the invasion that began on 18 February, greatly assisting U. S. forces in their conquest of that island. Truk was isolated by Allied forces, as they continued their advance towards Japan by invading other Pacific islands, such as Guam, Saipan, Palau, and Iwo Jima. Truk was attacked again from 12 to 16 June 1945 by part of the British Pacific Fleet during Operation Inmate. Cut off, the Japanese forces on Truk and other central Pacific islands ran low on food and faced starvation before Japan surrendered in August 1945.

Most of the roads and transportation systems are poor or in disrepair; an extensive infrastructural redevelopment plan began, consisting of a five phase project to completely reconstruct the existing sewer, water and storm drainage systems as well as pour concrete roadways in the majority of the villages of Weno. Chuuk International Airport (IATA airport code TKK) is on the administrative island of Moen. It is served by United Airlines. The government operates a radio station. Interisland communication is often accomplished using citizens' band radio. Telephone services are limited on Chuuk, though a cellular network is established within some islands of the lagoon and in the near future on the outer islands. High speed Internet access via ADSL has been made available on a monthly subscription basis on the Island of Moen from May 2010. Tourism, especially scuba diving among the many wrecks of Truk Lagoon, is the island's main industry. Copra (dried coconut meat) is the only cash crop, and output is relatively insignificant. Most of the inhabitants of outlying islands engage in subsistence activity only.

In 1969, William A. Brown and French oceanographer Jacques Cousteau and his team explored Truk Lagoon. Following Cousteau's 1971 television documentary about the lagoon and its ghostly remains, the atoll became a scuba diving lure, drawing wreck diving enthusiasts from around the world to see its numerous, virtually intact sunken ships. The shipwrecks and remains are sometimes referred to as the "Ghost Fleet of Truk Lagoon". Scattered mainly around the Dublon (Tonowas), Eten, Fefan and Uman islands within the Truk group, several shipwrecks lie in crystal clear waters less than below the surface. In waters devoid of normal ocean currents, divers can easily swim across decks littered with gas masks and depth charges, and below decks can be found evidence of human remains. In the massive ships' holds are the remnants of fighter aircraft, tanks, bulldozers, railroad cars, motorcycles, torpedoes, mines, bombs, boxes of munitions, radios, plus thousands of other weapons, spare parts, and other artifacts. Of special interest is the wreck of the submarine I 169 Shinohara which was lost when diving to avoid the bombing. The submarine had participated in the attack on Pearl Harbor in December 1941. The coral encrusted wrecks attract a diverse array of marine life, including manta rays, turtles, sharks and corals. In 2007, 266 species of reef fish were recorded by an Earthwatch team, and in 2006 the rare coral Acropora pichoni was identified. On 12 April 2011, the Australian Broadcasting Corporation program Foreign Correspondent screened a report on Chuuk Lagoon likening the effect of the impending massive release of tens of thousands of tonnes of oil from the rusting Japanese warships into the coral reef to that of the Exxon Valdez spill in Alaska. However, given the poor state of the Japanese war effort in 1944, many of the ships may have had relatively small amounts of fuel in their bunkers. Environmental protection organizations are surveying the wrecks while also consulting with Japanese researchers to try to determine how much oil is likely to be in the hulls, particularly in three sunken oil tankers. The ships are classified as a Japanese war grave, requiring Japanese government involvement in the eventual clean up.
