Mit der amerikanischen USS Nautilus wurde am 30. Ein Atom-U-Boot ist ein Unterseeboot, das die Energie für seinen Antrieb und seine Bordsysteme aus einem oder mehreren Kernreaktoren bezieht. Atomic submarines have the advantage of an almost unlimited range compared to the usually smaller and more cost-efficient submarines with conventional drives, such as the electric drive, and the fact that in the case of atomic submarines, the duration of the dives can only be reduced by The food supplies on board is limited. At present, six nations are operating nuclear-powered boats These are the United States of America, Russia, France, Great Britain, the People's Republic of China and India. The first nuclear submarine was put into service on Septemwith the American USS Nautilus. It took five weeks until U9 was ready for exhibition and accessible to visitors.Atom-U-Boot An atomic submarine is a submarine that refers to the energy for its propulsion and its system of one or more nuclear reactors. Thousands of people came out for the transport and gave the U9 an "escort", so to speak. Once arrived in Speyer, the submarine was taken on a special low-loader at walking pace along the main road to the museum. Some of the transport also took place over night due to time pressure. The Dutch special ship "Sirius" pushed the "Lastdrager" with the submarine in front of it. Then the 606-kilometre journey to Speyer began. After this, the pontoon and cargo resurfaced, with a total weight of 1,875 tons, and the ballast water was bailed. The pontoon was lowered into the harbour basin and two tugs towed the submarine on top of it.ĭivers adjusted the U9 submarine for "swimming into" the transport saddles, which were specially manufactured and attached to the pontoon. Loading the 420-tonne submarine onto the "Lastdrager 14" pontoon was a feat. After 36 hours of travel time, the tug arrived at the Dutch naval port of Rotterdam. The 280 nautical miles to Rotterdam needed to be covered. The attempt then started on 13 August 1993, three days late. North of the island of Wangerooge, the tug had to turn around at wind force 9 and sail back to Wilhelmshaven. The deep-sea tug boat Apollo, under the leadership of Captain Rypkema, was attached to the submarine with a hook and towed it through the North Sea to Rotterdam. The endeavour had begun in the Wilhelmshaven naval arsenal, where the boat had been located since it was taken out of service on 3 June 1993. The submarine was powered by two MB four-stroke diesel engines and two propulsion generators.Īfter an extraordinary voyage of 1,000 kilometres, the former German Navy U9 submarine arrived in Speyer on 20 August 1993. The 21 crew members were able to stay underwater for days with the modern underwater location system and snorkelling facilities. Thanks to the special shape of its hull, the U9 travelled faster underwater than above the surface. The exhibit on display in Speyer was registered with Nato as S-188. The ship spent 16,478 hours and 11 minutes submerged, which corresponds to a year and 11 months spent underwater. During its service, the U9 travelled 174,850 nautical miles, which is equivalent to eight trips around the world. It was decommissioned in 1993 as part of the reduction in military capacity. The U9 dates from 1966 and was put into service in Kiel's Tirpitzhafen harbour. In addition to the U9, many small submarines can also be seen in the museum. The nominal dive depth was 100m and it was armed with eight bow torpedo tubes. It weighs 466 tonnes, is 46m long, 5m wide and had a draught of 4m. It belongs to submarine class 205, making it part of the third generation of German submarines. The U9 submarine was built by Howaldtswerke in Kiel and put into service on 11 April 1967. One highlight of the Technik Museum Speyer is an original German Navy submarine, which visitors to our museum can also view from the inside.
