HTMS Sattakut (LCI-742) Shipwreck on Koh Tao
Koh Tao, Thailand
Big Blue Tech observed the Thai navy sink one of their own ships today on Koh Tao to provide an artificial reef and wreck diving resource just off the shore from our resort.
The HTMS Sattakut was origionally owned by the US Navy. During World War II USS LCI(L)(G)(M)-739 was assigned to the Asiatic-Pacific Theater and participated in the assualt and occupation of Iwo Jima and Okinawa in 1945.
Plans to dive the new wreck are already underway with undoubtedly hundreds of divers just waiting for the conservation society to finish counting the sea stars and let us have at it. We’re expecting a chance to dive it within the week.
The ships unique bow design allowed troops to assault beaches in the security and shelter of it’s forward guns and Armour. This gives the wreck an unusual appearance.
