Japanese battleship Nagato
Raja Ampat · Indonesia
The Japanese battleship Nagato, a veteran of World War II and the flagship of Admiral Isoroku Yamamoto, met its final fate as a target ship during Operation Crossroads nuclear tests in Bikini Atoll in 1946. This massive super dreadnought now rests inverted on the seabed, offering an imposing and historically significant deep wreck dive. Its sheer size and the dramatic events surrounding its sinking make it a poignant underwater monument.
