Chuuk was originally part of the colonial territory of the Caroline Islands, and as such Chuuk has been a part of the Spanish Empire, then the German Empire and finally the Japanese empires.
During World War II, Chuuk Lagoon was the Japan’s main naval base in the South Pacific theatre. A significant portion of the Imperial Japanese fleet was based there, with its administrative center on Tonoas (south of Weno). Due to its heavy fortifications, both natural and manmade, the base at Chuuk was nicknamed by the Allied forces as “the Gibraltar of the Pacific”. In 1944 the U.S. forces attacked Chuuk under code name Operation Hailstone. The attack culminated in one of the most important naval battles of the war. Twelve Japanese warships, thirty-two merchant ships and 249 aircraft were destroyed.
After the War, Chuuk was one of six districts of the Trust Territory of the Pacific Islands which were administered by the United States under charter from the United Nations from the end of the Second World War to the early 1990s. Now Chuuk is a state within the independed Federated States of Micronesia.

In 1944 the US Navy conducted Operation Hailstone, the largest surface bombing campaign in history, wiping out a Japanese fleet stationed at the island. The seabed around Chuuk is now littered with nearly 70 wrecks of ships and planes, all protected from deep sea currents by a reef system, and most within depths appropriate for scuba divers.
Although Truk Lagoon contains a number of spectacular wrecks, the Fujikawa Maru is often singled out by diving magazines and travel guides as one of the top 10 wreck dives in the world.
However, apart from scuba diving, there is not very much to do in Chuuk. There are no real beaches on Weno (although some of the outer islands which can be reached by boat do have beaches). None of the hotels on Chuuk even has a swimming pool. For non-diving spouses, a trip to Chuuk can be a dull and tiresome affair.
