Chuuk Lagoon: Micronesia's Underwater World War II Museum

Overview

Beneath the calm turquoise waters of the western Pacific lies one of the world's largest underwater museums. Chuuk Lagoon preserves dozens of World War II shipwrecks and aircraft, creating an extraordinary destination where history, marine life, and adventure come together.

Chuuk Lagoon, formerly known as Truk Lagoon, is a large sheltered lagoon in the State of Chuuk within the Federated States of Micronesia. Surrounded by a barrier reef and volcanic islands, the lagoon served as the principal naval base of the Imperial Japanese Navy in the central Pacific during World War II. In February 1944, Operation Hailstone launched by the United States devastated the base, sinking dozens of ships and aircraft that remain beneath the lagoon today.

Today, Chuuk Lagoon is internationally recognized as one of the world's premier wreck-diving destinations. Coral reefs, tropical fish, sea turtles, and other marine life have transformed the historic wrecks into thriving underwater ecosystems, making the lagoon a place of both remembrance and natural beauty.
