HMAS ''Yarra'' (M 87) is the sixth ''Huon''-class minehunter to have been built for the Royal Australian Navy (RAN) and the fourth warship to be named after the Yarra River in Victoria. Built by a joint partnership between Australian Defence Industries (ADI) and Intermarine SpA, ''Yarra'' was constructed at ADI's Newcastle shipyard, and entered service in 2000. ==Design and construction== (詳細はBay class minehunters. The tender was awarded in August 1994 to Australian Defence Industries (ADI) and Intermarine SpA, which proposed a modified ''Gaeta''-class minehunter.〔 ''Yarra'' has a full load displacement of 732 tons, is long, has a beam of , and a draught of .〔Saunders (ed.), ''IHS Jane's Fighting Ships 2012-2013'', p. 33〕 Main propulsion is a single Fincantieri GMT BL230-BN diesel motor, which provides to a single controllable-pitch propeller, allowing the ship to reach .〔Wertheim (ed.), ''The Naval Institute Guide to Combat Fleets of the World'', p. 23〕 Maximum range is at , and endurance is 19 days.〔〔 The standard ship's company consists of 6 officers and 34 sailors, with accommodation for 9 additional (typically trainees or clearance divers).〔 The main armament is a MSI DS30B 30 mm cannon, supplemented by two 0.50 calibre machine guns.〔 The sensor suite includes a Kelvin-Hughes Type 1007 navigational radar, a GEC-Marconi Type 2093M variable-depth minehunting sonar, an AWADI PRISM radar warning and direction-finding system, and a Radamec 1400N surveillance system.〔 Two Wallop Super Barricade decoy launchers are also fitted.〔 For minehunting operations, ''Yarra'' uses three Riva Calzoni azimuth thrusters to provide a maximum speed of : two are located at the stern, while the third is sited behind the variable-depth sonar.〔 Mines are located with the minehunting sonar, and can be disposed of by the vessel's two Double Eagle mine disposal vehicles, the Oropesa mechanical sweep, the Mini-Dyad magnetic influence sweep, or the towed AMASS influence sweep (which is not always carried).〔 To prevent damage if a mine is detonated nearby, the ships were built with a glass-reinforced plastic, moulded in a single monocoque skin with no ribs or framework.〔 As the ships often work with clearance divers, they are fitted with a small recompression chamber.〔 ''Yarra'' was built by Australian Defence Industries in Newcastle, New South Wales, launched on 19 January 2002, and commissioned into the RAN on 1 March 2003.〔 ''Yarra'' is based at HMAS ''Waterhen'' Naval Base in Sydney, along with the majority of the RAN's mine warfare assets.〔 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「HMAS Yarra (M 87)」の詳細全文を読む スポンサード リンク
