Unlike the American boat it was single-hulled, and had very large, almost wing-like, hydroplanes on the lower hull. It wasn’t a straightforward copy of the Albacore however. Launched in 1953, this boat featured a revolutionary new hull form which allowed it to go faster underwater than on the surface. The highly streamlined hull and unusual rudder mounted on the aft of the fin were no doubt influenced by the USS Albacore, the design details of which Sweden was privy: Reconstructed from fragments of plans in Swedish archives. One possibility is that, like some of the follow-on designs, this boat did not have any torpedo reloads which allowed the removal of the conventional torpedo room, thus shortening the boat and reducing crew requirements. The first plans for the Swedish nuclear submarine had a hull diameter of 6.1m (20ft) and an overall length of just 42m (138ft), making it small even by Swedish submarine standards. This Covert Shores Recognition Guide Covers over 80 classes of submarines including all types currently in service with World Navies. Get The essential guide to World Submarines Instead nuclear power was seen as a possible answer to speed and endurance, allowing a relatively small submarine to quickly counter an invading (Soviet) fleet.Įarly official sketch of the nuclear powered A-11A concept. Swedish submarines are not ice-hardened and are susceptible to damage if attempting to surface through ice. The motivation for nuclear submarines does not appear to have been under-ice operations in the Northern Baltic. Therefore nuclear power was considered for the next generation A-11 submarine project. Sweden, one of the few submarine building countries at the time, did not want to be left behind. The UK and France quickly began their own nuclear submarine programs, as did Italy (later abandoned). The US Navy launched the world’s first nuclear powered submarine on 21st January 1954, followed by the first Russian NOVEMEBER Class boat on 9th August 1957. It was conceived at a time when it was widely expected that virtually all vessels, cars, planes and trains would be nuclear powered at some point in the future. A-11B – Battery (diesel-electric) propulsionĪll the same the nuclear-powered A-11A should get the most attention.Although they were labelled A-B-C, the order of priority was as follows: The forward half of the boat would be the same, only the propulsion differed. The A-11 program was split into three design streams, each with a different propulsion system. This article summarizes the major features of the nuclear and AIP designs which were part of the journey to the conventionally powered A-11 Sjöormen Class. Yet Sweden was one of the first countries to pursue a nuclear powered submarine, starting development in 1957. Today, Sweden is known for its AIP (Air Independent Power) submarines. Sweden's Nuclear Submarine: The A-11A 'Atomic' In addition to drawing closer to Moscow, Tehran has sought improved relations with China, which brokered an agreement last month to restore diplomatic ties between Iran and Saudi Arabia.Many thanks to everybody who has helped with the research for this article, and in particular to Fredrik Granholm for masses of materials, patience and guidance. The tensions have worsened as Iran has supplied attack drones to Russian forces in Ukraine and as Israel and Iran have escalated their yearslong shadow war in the Middle East. The Biden administration’s efforts to restore the agreement hit a wall last year. U.S.-Iranian tensions have soared since then-President Donald Trump withdrew from a 2015 agreement with world powers that provided sanctions relief in return for Iran curbing its nuclear activities and placing them under enhanced surveillance. They were famously employed during the opening hours of the 2003 U.S.-led invasion of Iraq and in response to a Syrian chemical weapons attack in 2018. Tomahawk cruise missiles launched from ships or submarines can hit targets up to 2,500 kilometers (1,500 miles away). contractor and wounded seven other Americans in that country’s northeast. launched airstrikes against Iran-backed forces in Syria after a rocket attack killed a U.S.
