Adventure Travel – Bikini Atoll
Bikini Atoll – Marshall Islands
Bikini Atoll is part of the Republic of the Marshall Islands, which covers nearly 1 million square miles of idyllic emerald-green coral atolls, surrounded by the crystal-blue waters of the Pacific. A one of a kind diving paradise, as it features not only beautiful reefs, corals and wonderful marine life. Above all, it is the final resting place for some of the most significant warships in history. Bikini Lagoon is the first UNESCO World Heritage site for the Marshall archipelago and is undisputedly ranked first on any serious wreck divers’ bucket-list. This is well justified; nowhere else on earth you will be able to dive such a unique collection of historic battleships, cruisers, as well as the world-famous USS Saratoga aircraft carrier with its 270m (888ft.) flight deck.
As most wrecks at Bikini Atoll are beyond recreational depth limits, this itinerary is recommended only for technical divers with previous wreck experience.
Generally, there are two dives per day and the typical schedule will be as follows:
- Breakfast followed by a briefing & Dive 1
- Lunch, relaxation followed by briefing & Dive 2
- Snack, relaxation,
- Dinner
Explosive history
In 1946, following the end of World War II, the United States gathered together a “mock” naval fleet in order to test the effects of atomic bomb blasts on a large naval fleet. They named it Operation Crossroads and designated Bikini Atoll to be one of the sites for the explosive tests, with the local inhabitants displaced to another atoll. More Operations followed suit; from land, on the reef, on the sea, from the air and underwater. Between 1946 and 1958, the United States tested a grand total of 67 nuclear weapons on the Marshall Islands, of which ‘Castle Bravo’ on Bikini Lagoon in 1954 is the best-known. This 15-megaton TNT hydrogen atomic bomb was a thousand times more powerful than the bomb dropped on Hiroshima. It left a crater in the lagoon of 2 kilometres wide and 76 metres deep. Bikini Atoll was opened for diving in 1996, allowing divers to experience some of the most historic and unparalleled wreck diving in the world.
What does the package include?
11 days/ 10 nights/6 days technical diving on M/V Truk Master, double occupancy, transfer to the boat, daily breakfast, lunch, dinner, snacks, non-alcoholic beverages daily, cylinders, weights, and trip brochure and packet, trip shirt, and travel leaders,
Eric Keibler will lead the group. This is a Technical Diving Location.
Is there Technical Diving?
As most wrecks at Bikini Atoll are beyond recreational depth limits, this itinerary is recommended only for technical divers with previous wreck experience. The average depth of the wrecks is around 50 meters (150 ft). To get the most out of your dives in Bikini Atoll, highly recommended minimum certifications are:
- SSI XR – Technical Extended Range
- IANTD – Technical Nitrox
- TDI – Advanced Nitrox & Deco Procedures
- NAUI – Tech Nitrox & Deco Techniques
- ANDI – Technical Nitrox and
- PADI – Tec 50
Depth limits given by the Cruise Director must be followed and wreck penetration is not allowed without a dive guide. The boat has decompression mixes available at an additional charge. Technical divers w
ill be permitted to extend their bottom times to the extent of their training and certification.
While the boat offers helium on-board, due to the logistical difficulties of obtaining it and the resultant costs, Trimix is only available to CCR divers but you must have the appropriate certification.
May I dive my rebreather?
This is a rebreather friendly trip and using rebreathers is encouraged. There will be an additional charge for rebreather cylinders, oxygen fills, helium and sorb. Rebreather divers need to notify us as soon as possible to make sure the boat brings the sorb and cylinders to the boat.
Where will we be diving?
Between 1946 and 1958, not less than 23 atomic bombs were tested at Bikini Atoll only, which resulted in a unique selection of shipwrecks consisting of war battleships, cruisers, and an aircraft carrier. In March 1954, the notorious dry fuel hydrogen bomb ‘Castle Bravo’ was detonated in Bikini. This bomb was the US’ most powerful nuclear device ever; 1000 times more powerful than the atomic bomb dropped on Hiroshima. It left a crater of 2km wide and 76m deep in the lagoon of Bikini.
More than 60 years later, the shipwrecks remain equally as impressive while they have become home to many kinds of corals and fish species.
USS Saratoga
The signature dive of Bikini Lagoon: the USS Saratoga CV-3. This 270 metres (888ft) long and 29 metres (95ft) wide American aircraft carrier weighs 39,000 tons and rests in Bikini Lagoon at a depth of 52 meters. Her bridge is easily accessible at 18 metres depth, her flight deck at 28 metres, and the hanger for the Helldivers at 32 metres. These Helldivers and bombs are still on display complete with all dials and controls. Remarkable detail: the Japanese reported her sunk 7 times during World War II. The Saratoga did, however, suffer damage on multiple occasions during the war and was therefore chosen to be used as a testing target in Bikini
Nagato
This battleship was built for the Imperial Japanese Navy as the first super-dreadnought to mount 16-inch (406 mm) guns. With a cruising speed of 26.5 knots, this made her the Imperial Navy’s flagship as well as one of the most powerful and versatile warships in the world at that time. She measures 221 metres (725ft) in length and 29 metres (95ft) wide and her crew used to comprise of 1734 men. After the Japanese surrender, the Nagato was seized, used for testing and sank during Operation Crossroads in July of 1946.
USS Arkansas
An American dreadnought, measuring 171 metres (562 ft) long and armed with twelve 12-inch guns and capable of a top speed of 20.5 knots. The USS Arkansas served in both World War I and World War II; escorting convoys in the Atlantic and bombarding shore targets during the invasions of Normandy, Iwo Jima and Okinawa. She was moored only 500 ft. away from the intended atomic bomb detonation in 1946 and was supposedly lifted up vertically within the blast column. She sank completely only 19 minutes after the blast, ending almost completely upside down on the sandy bottom at 55 metres depth.
USS Pilotfish
An American Balao-class submarine; she measures 95 metres (311 ft) in length and 8.3 metres (27 ft) wide and was previously used to perform lifeguard and offensive patrolling duty all over the Pacific. In 1946, the Baker underwater atomic bomb test compressed her hull and forced all the ledges and valves to open and made her sink completely.
USS Lamson
The American Mahan-class Destroyer ship appears almost like a pirate ship underwater. With her length of 104 metres, she might not be the biggest of the Bikini wrecks but nevertheless very interesting to explore as she features several guns, torpedoes, bombs and generally provides good access to divers in water with great visibility.
Prinz Eugen – Kwajalein Atoll
Being a war prize awarded to the USA by Britain after WW II resulted in the atomic fate for this German heavy cruiser. She survived the blasts of Operation Crossroads, even though she was already damaged, and she was towed to Kwajalein where she ultimately capsized and sank to her final resting place in December 1946. Nowadays, a part of the ship is still visible above water.
USS Anderson
The Sims-class destroyer of 106 metres (348ft.) long by 11 metres (36ft) wide was built in 1939. She served at different locations in World War II; she participated in fighting battles in the Atlantic and the Pacific using her machine guns, anti-aircraft missiles and torpedoes, taking down many enemy aircraft. USS Anderson also helped in anti-submarine warfare.
USS Apogon
A second submarine of the Balao-class that headed straight for Hawaii and the Marshall Islands after her launch in 1943. Patrolling designated areas in the South Pacific and attacking enemy (i.e. Japanese) ships were her duties. The Apogon lies completely intact at a depth of 48 meters with an average depth of 43 metres. Explore the conning tower, viewing binoculars on the bridge, and propellers covered by red sponges.
USS Carlisle
A Gilliam-class attack support boat, 130 metres (426 ft) long and 18 metres (58 ft) wide that served as merchant vessel transporter within the US Navy in the Second World War. Finished and acquired by the Navy in 1944, she arrived late into the war and was assigned to transport operations; of which she only performed 3. Hence, she never participated in any combat situations. She sank in 1946 during the Operation Crossroads, resting upright in the sand at 51 metres depth and her deck at 40 metres.
Sakawa
The Japanese Agano-class light cruiser (162 metres, 532 ft long by 15 metres, 49 ft wide) was armed with ‘second hand’ guns previously fitted on other war ships. She was the only survivor of her class after the war and was surrendered to the United States in 1945 who used her for repatriation duties. She was heavily damaged by the atomic tests Able and Baker in 1946; everything after the bridge was squashed flat as if stepped on by a giant foot. She was positively re-identified after the atomic bomb blasts only in 1992.
