Location
Truk Lagoon is located in Chuuk State (Truk) in the Federated States of Micronesia. Also known as "Chuuk Lagoon". Truk consist of eleven major islands and many smaller islets within a forty mile wide lagoon surrounded by a protective reef. To the southeast is Kuop Atoll (Neoch Atoll).

Wartime History
On November 15, 1939, the Imperial Japanese Navy (IJN) Fourth Fleet (4th Fleet) under the command of Admiral Katagiri Eikichi is established at Truk. Chitose is assigned as flagship with tenders Kamoi and Kinugasa Maru of the 17th Sentai for the new fleet. During December, twenty-four H6K Mavis flying boats from the Yokohama Kokutai were stationed at Truk Lagoon.

Allied missions against Truk
January 15, 1941 - June 30, 1945

Operation Hailstone
On February 17, 1944 during the morning, U. S. Navy (USN) carrier aircraft from USS Intrepid CV-11 and USS Essex conducted a surprise attack against Japanese ships anchored in Truk Lagoon, dropping 400 tons of bombs and torpedo. Attacks continued February 18, 1944. In total, forty ships were sunk and thousands of Japanese died. Ten weeks later, a second raid sank more ships. Truk was strategically bypassed and neutralized by island hopping and aerial attack by Allied aircraft.

Postwar
For more than two years after the Pacific War, oil from the sunken ships covered the beaches and reefs.

Today
For more than two years after the war, oil from the sunken ships covered the beaches and reefs. Truk is best wreck diving in the world overall because of the numerous wrecks and their preservation and beauty. Depths vary from the surface in excess of 200 feet. You can penetrate into the wrecks but you can't remove any artifacts. Caustic substances like high octane aviation fuel, oils, gasoline and acid exist on many of the wrecks. Explosives, mines, munitions, detonators, torpedoes and shells are still "live". The wrecks of Truk Lagoon are war graves. Strict policies exist that prevent the removal of any artifacts or marine life from the wrecks. Fines and a possible jail sentence await those who disobey. The Trukese hope preserve their lagoon as an underwater living monument and museum of the war.
