Stridsbåt 90 H(alv) (Strb 90 H, literally: Combat Boat 90 Half; the ''90'' refers to the year of acceptance and ''Half'' refers to the fact that it can carry and deploy a half platoon of amphibious infantry (18 men) fully equipped) is a class of fast military assault craft originally developed for the Swedish Navy by Dockstavarvet. In addition to the many variants in service with the Swedish Navy under the "Stridsbåt 90H" designation, the CB 90 has been adopted by the navies of several countries, including Norway (as the S90N), Greece, Mexico (as the CB 90 HMN), and Malaysia. Also the German Navy plans to equip the ''Berlin''-class replenishment ships with the CB90. The CB90 is an exceptionally fast and agile boat that can execute extremely sharp turns at high speed, decelerate from top speed to a full stop in 2.5 boat lengths, and adjust both its pitch and roll angle while under way. Its light weight, shallow draught, and twin water jets allow it to operate at speeds of up to in shallow coastal waters. The water jets are partially ducted, which, along with underwater control surfaces similar to a submarine's diving planes gives the CB90 its manoeuvrability. == History == In 1988, Dockstavarvet won a competition to design and manufacture a replacement for the aging Tpbs 200 class. Two prototypes, with pennant number 801 and 802, were delivered in 1989. After completion of field trials, the Swedish Navy signed a purchase order for 120 boats in June 1990. In 2002, the Swedish Navy ordered an additional 27 boats of a slightly different type, designated Stridsbåt 90 HS - where S refers to ''Skydd'' (''protected'')〔 as the Strb 90 HS is armoured and features CBRN protection (the whole boat can be over-pressurized) - intended for use in international peace-keeping operations. Apart from the addition of armour, it sports air-condition for deployment in tropical conditions, fuel cooling system, 220V generator and more powerful engines. The manufacturer sometimes refers to the model as the ''CB 90 HI'', where the I probably stands for International. Several of the tasks carried out by the Strb 90 H-variants, were originally intended for the Strb 90 E, which is now almost completely phased out. The Royal Norwegian Navy evaluated the Strb 90 H in early 1996, and subsequently purchased a total of 20 boats, designated 90 N (for ''Norsk utgave'', literally ''Norwegian version''). The Mexican Navy acquired 40 units (designated CB 90 HMN) between 1999 and 2001, and obtained a production license in 2002, allowing further units to be manufactured in Mexico. Since then eight additional units have been built. The German Water Police rented a Combat Boat 90H from the manufacturer Dockstavarvet for the 33rd G8 summit in Heiligendamm, Germany. This boat was involved in a high speed chase with three Greenpeace RIBs which were trying to enter the restricted area near the hotel where the meeting was being held. A video clip of the incident was later widely spread around the internet.〔(SvD article )〕〔(Greenpeace-Boote dringen in G-8-Sperrzone ein )〕 In July 2007 The United States Navy Expeditionary Combat Command (NECC) specified the CB90 for testing as its Riverine Command Boat. Safeboat International of Port Orchard, Washington, was given a US$2.8 million contract to produce one prototype. In June 2009 an unknown buyer from Abu Dhabi bought two civilian luxury versions.〔(Di article )〕 In 2010, Dockstavarvet Shipyard modified two CB90's to be carried in the davits of Dutch and UK Navy Landing Platform Dock's. During these six months trials, the two boats and a full Swedish boat squadron were embarked on a Royal Netherlands Navy LPD as a fully integrated element of the amphibious forces aboard and successfully deployed. In 2013 JSC Pella Shipyard near St Petersburg launched the first Russian built Project 03160 "Raptor",〔(Finishing trials of fast special-purpose boat (Rus) )〕 but while the ships are strikingly similar there is no indication Dockstavarvet has been involved or licensed the design to Pella. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「CB90-class fast assault craft」の詳細全文を読む スポンサード リンク
