Truk Lagoon, Chuuk, discover over 70 authentic World War II wrecks!
Welcome to diving in TRUK LAGOON in Chuuk State, Federated States of Micronesia! This vast oceanic lake with high islands and a 290-kilometer-long barrier reef surrounding it served as a naturally protected base for Japan's conquest of the entire Western Pacific, leading to fierce fighting by Allied forces to end military dominance. A massive Allied attack code-named "Operation Hailstone" in February 1944 and two subsequent attacks in April and June left the floor of the lagoon and islands of Truk with a huge amount of destroyed aircraft and cargoes of sunken warships.
Coral-encrusted WWII shipwrecks and wide varieties of Indo-Pacific aquatic life including sharks and huge schools of tropical fish.
