Truk Lagoon Expedition 2010

Gosei Wreck Engine Room

Exploring the sunken fleet of the infamous Truk Lagoon.

Diving Truk Lagoon is the dream of many divers. But few realise that this is within the reach not only of rebreather and trimix divers. Many of the wrecks lie within recreational diving limits and enable divers with a reasonable level of confidence and experience to enjoy some of the World’s most incredible wrecks.

The 2010 expedition was led by Leigh Bishop and Pete Mesley catering for ALL levels of diving from advanced recreational divers to Trimix rebreathers, with wreck sites chosen to maximise the adventure for all participants. Two further expeditions in 2011 are planned to continue documenting this amazing site. More details coming soon...

  • The Destination

    Truk lagoon Panoramic

    Truk Lagoon (Chuuk) is a very special place that has taken a cruel and ugly part of its history and turned it into something beautiful. During WWII Truk Lagoon was a centre of wartime activity. The heritage it left, buried under the sea, has become a haven for coral and fish life. It is a maze of military wrecks waiting to be explored. Here in this special underwater world you will find every kind of military equipment that you can imagine—ships, submarines, planes, bulldozers, ammunition, cannons, tanks, jeeps, medical supplies and much more.

    Near the end of WWII the US Navy unleashed the full fury of Operation Hailstone on the Japanese Imperial 4th Fleet stationed in Truk Lagoon. In the blaze of battle, 100’s of thousands of tones of Japanese naval ships, tankers, cargo ships, and planes disappeared beneath the sea. Operation Hailstone was six times more powerful than the Japanese attack on Pearl Harbour and these tragic events have created an area that has been declared a national monument.

    For wreck divers, the events have also created a uniquely haunting and enchanting environment. As you sink down the anchor line beneath the warm, 30 degree blue water, history comes to life in the eerie tranquility. The awe inspiring nature of the wrecks, and the tragedy and violence of their arrival at the bottom of the ocean, jarringly contrasts with the beauty and life that now surrounds them. In their destruction, these wrecks have found the most beautiful of graves.

  • Some of the Wrecks in Truk Lagoon

    San Francisco Maru — lying upright at a depth of 48m to 60m, this medium sized freighter carried military equipment. Loaded with so much war material, it is often nicknamed ’the Million Dollar Wreck’. You will also find the bow gun, ship’s bell, and an open safe.

    Nippo Maru—check out the wheelhouse for a great photo stop. This is a deeper dive and dives are limited to the bridge and deck areas.

    Nagano Maru—3800 ton army transport the wreck lies upright on the seabed. Top of the bridge lies in 45m with the deck sitting in 50m, 60m to the sand.

    Oite— One of the deepest wrecks in Truk. A Kamikaze Class Destroyer 1500 tons. Sitting between 60- 70m broken in two. This wreck has been rarely dived and has amazing artifacts.

    Katsuragisan Maru— Cargo vessel of 2400 tons sitting in 60-70m of water, rarely dived by people so again another virginal wreck. This is the deepest wreck in Truk!

    Rio-De Janeiro Maru— 9600 ton ocean liner. This is not a deep ship max depth 34m to 12m!! But we can have the most fun on this vessel exploring the internals. Not all these ships we will be diving will all be deep. And divers will be placed according to their qualifications and experience.
