USS Emmons

Highly recommended dive point in Okinawa
maximum depth 45m
It is said to have been sunk by the U.S. military itself during World War II to prevent leakage to Japan.
The destroyer Emmons was attacked by five Japanese suicide planes with severe hull damage.
This historic ship lies on the north side of Kouri Island – at a depth of 45 meters. The length is about 106m
Due to the weathering of the hull over the years and typhoons, a part of the bow of the ship collapsed at the end of 2022.
