Bikini Atoll Diving
The Marshall islands diving liveaboard is a haven for wreck enthusiasts. Diving the Bikini Atoll’s sunken fleet of former naval vessels is an entirely unique experience.
The Bikini Atoll, a UNESCO World Heritage site, is in the Marshall Islands archipelago and is a wreck divers paradise. Underwater, there are a unique collection of historical World War II battleships, the remnants of post-war testing for nuclear bombs.
The Bikini lagoon and atoll first opened to divers and tourism in June of 1996 once the islands original inhabitants returned to Bikini.
A large ‘mock’ naval fleet was assembled to record the impact that the 67 atomic bombs would have on them. Most of the ships sank as a direct result or very soon after. Now 60 years on, the wrecks are now encrusted with corals and surrounded by fish life. Moreover, scuba diving in the Marshall Islands is now high on any wreck diving enthusiast’s destination wish list.
The underwater fleet consists of naval destroyers, submarines, cruisers and attack ships. As a result of the testing, Bikini Atoll has the only aircraft carrier inside the recreational dive limits. This maritime fleet is the only wreckage ever sunk by an atomic bomb, making it truly unique.
Divers can expect to see torpedo tubes, depth charges, flight decks on Japanese and United States wrecks. The USS Lamson sits upright and some diving operations may visit it.
Divers must be advanced to join, and many wrecks are beyond recreational depths.

In 1946 Bikini’s inhabitants were moved to another atoll so it could become the site for explosives testing on a large scale in the post-war years under Operation Crossroads.
Tourism began in 1996 when Bikini Atoll was opened to the public for divers to experience some of the most historic wrecks in history.
Best Places to Dive in Bikini Atoll
The unique shipwrecks of Bikini Atoll were formed by the ‘mock’ naval fleet being created for nuclear weapons testing on a large scale fleet. Not less than 23 atomic bombs were tested in the area between 1946 and 1958 under the Operation Crossroads framework and several other code names.
This includes the infamous March 1954 Castle Bravo hydrogen bomb 1000 times more powerful than that used at Hiroshima. This particular test left a crater 2km wide and 76m deep.
There has been some resistance to the Marshall Islands and Bikini Atoll being opened up to tourism. The Island residents themselves decided to invite tourists as a way to tell their story and keep it alive. Guests on board will view historical footage of documentaries telling their story as well as island tours of the atoll area.
Best Dive Sites in Bikini Atoll
This is the most famous dive in Bikini Atoll. The Saratoga is the only aircraft carrier that is within diveable limits and the largest wreck. Less than 10% of the vessel has been explored so far with no penetration inside the engine room.
Parts of the wreck are less than 20m deep and within easy reach of divers.
A German cruiser was scuttled due to being radioactive as she survived some test explosions. Part of her is still visible above the water line, and her port propeller was salvaged and is at the German Naval Memorial at Laboe. Her bell was also removed and is at the Naval Museum in Washington DC.
A Japanese battleship that was the first to have 16-inch guns to her hull. She lies capsized at 48-50m of depth with the bridge area at 45m. She was one of the most powerful and versatile war vessels during her time and was the flagship of the Imperial Japanese Navy during the Pearl Harbour attack.
She was an American dreadnought and is 171m in length. She was capsized in 55m of depth in nuclear test Baker in 1946. She lies on her starboard side, and the propeller shafts are visible as are two submarines one in pristine condition.
