''Harry DeWolf''-class offshore patrol vessel is a Government of Canada procurement project for the Royal Canadian Navy (RCN) that is part of the National Shipbuilding Procurement Strategy. The class was previously referred to as Arctic Offshore Patrol Vessel (AOPS). In July 2007 the federal government announced plans for acquiring 6-8 icebreaking vessels for the RCN.〔 〕 The vessels have been speculated to be modelled on the Norwegian ''Svalbard'' class and as of 2007 are projected to cost $3.5 billion CAD to construct with a total project procurement budgeted to cost $4.3 billion in order to cover maintenance over the 25-year lifespan of the vessels. Lead ship of the class was announced as in September 2014, and an additional four ships were named in January 2015. Construction of the ships ''Harry DeWolf'' and started in September 2015 at Halifax Shipyards. Both ships are expected to be have been delivered and entered service by Spring 2018. and will begin construction in September 2016, with a 2019 delivery date. and the yet to be named sixth vessel, are planned to be in service by 2020. Both ''Harry DeWolf'' and ''Margaret Brooke'', are planned to be retired from service and decommissioned by 2043. ==Project history== In 2006 Prime Minister Stephen Harper had spoken about building three to four icebreakers capable of travelling through thick ice in the Arctic Ocean.In 2007 it was announced that the Canadian Forces would purchase six to eight patrol ships having an ice class of Polar Class 5, meaning that they were capable of limited ice breaking, based on the ''Svalbard'' class.〔 This announcement was met with some controversy, and the proposed ships have been called "slush-breakers", by Dr. Gary Stern, a scientist aboard , and Jack Layton of the NDP.〔 〕〔 〕 However, it is notable that of the nineteen Canadian Coast Guard icebreakers currently in service, only six have a polar class higher than PC 5.〔 〕 In 2010 the Arctic Patrol Ship Project was grouped with several other federal government ship procurement projects for the Royal Canadian Navy and Canadian Coast Guard into the National Shipbuilding Procurement Strategy (NSPS). The NSPS announced on 19 October 2011 that Irving Shipbuilding would be awarded the $25 billion contract for building six to eight Arctic patrol ships as well as fifteen other warships for the RCN over the next two decades. In April 2013, the Rideau Institute and the Canadian Center for Policy Alternatives released a report on the proposed AOPS. The report was written by UBC Professor Michael Byers and Stewart Webb. The report's conclusion was that Canada would be better suited to have purpose built ships, namely icebreakers for the Arctic and offshore patrol vessels for the Pacific and Atlantic coasts. In May 2013, the CBC revealed that the projected cost of the design phase of the project was many times what other countries paid for similar ships based on the same Norwegian class for design, construction, and full-up operational deployment of multiple ships. Design is usually projected to consume 10-20% of the project cost. The projected design cost of the ship class is $288 million, versus an expert cost estimate that they should only cost $10–15 million to design. The Norwegians spent $100 million for the initial design and fielding of the first unit, NoCGV ''Svalbard''. The Danish built two ships for $105 million, and the Irish did the same for $125 million. In September 2014, Prime Minister Stephen Harper announced that the name of the first ship in the class would be Her Majesty’s Canadian Ship ''Harry DeWolf'', named in honour of wartime Canadian naval hero Harry DeWolf, and that the class would be named the ''Harry DeWolf'' class. In December 2014 it was found that not enough money had been projected to cover the cost of building the 6-8 planned ships and that the budget would need to be increased, delaying the signing of the contract. However, in an effort to drive down costs, Irving Shipbuilding could only project building 5 ships with the option to build a sixth only if it came under budget. The budget for the project was increased from $3.1 billion to $3.5 billion to insure a cash buffer. On 13 April 2015 the government announced a second ship would be named ''Margaret Brooke'' in honour of Margaret Brooke. During the Second World War, Brooke, a navy nursing sister, was decorated for her actions during the sinking of the passenger ferry . The third ship will we be named ''Max Bernays'' for Chief Petty Officer Max Bernays who served aboard during the Second World War and was decorated for his actions during the sinking of the . The fourth ship will be named for William Hall, a Victoria Cross (VC) winner from Nova Scotia who was the first black person to be awarded the VC for actions during the Siege of Lucknow. The fifth ship will be named for Frédérick Rolette, a French-Canadian sailor of the Royal Navy who, during the War of 1812, commanded the ship at the Battle of Lake Erie. On 18 June 2015 it was reported that construction was finally underway on the lead ship of the class ''Harry DeWolf''. 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「Harry DeWolf-class offshore patrol vessel」の詳細全文を読む スポンサード リンク
