HMCS ''Waskesiu'' was a of the Royal Canadian Navy. The frigate served as a convoy escort in the Battle of the Atlantic during the Second World War. It was the first frigate constructed and commissioned into the Royal Canadian Navy. Following the war, the vessel was sold to India where it was renamed ''Hooghly''. Named for the town of Prince Albert, Saskatchewan, there was already a warship named "Prince Albert". The Royal Canadian Navy then named the ship after the town closest to Prince Albert National Park.〔 ''Waskesiu'' was ordered in October 1941 as part of the initial 1942-1943 River-class building programme.〔〔Macpherson and Barrie, p.83〕 The ship was laid down on 2 May 1942 by Yarrows Ltd. at Esquimalt, British Columbia and launched 3 April 1943. The frigate was commissioned into the Royal Canadian Navy on 16 June 1943 at Victoria, British Columbia with the pennant number K 330.〔 ==Background== (詳細はRoyal Navy at the time, including the . The first orders were placed by the Royal Navy in 1940 and the vessels were named for rivers in the United Kingdom, giving name to the class. In Canada they were named for towns and cities though they kept the same designation.〔(【引用サイトリンク】title=Fact Sheet No. 21 – Canadian River Class Frigates )〕 The name "frigate" was suggested by Vice-Admiral Percy Nelles of the Royal Canadian Navy and was adopted later that year.〔Macpherson, p.6–7, 15〕 Improvements over the corvette design included improved accommodation which was markedly better. The twin engines gave only three more knots of speed but extended the range of the ship to nearly double that of a corvette at at 12 knots.〔 Among other lessons applied to the design was an armament package better designed to combat U-boats including a twin 4-inch mount forward and 12-pounder aft.〔 15 Canadian frigates were initially fitted with a single 4-inch gun forward but with the exception of , they were all eventually upgraded to the double mount.〔 For underwater targets, the River-class frigate was equipped with a Hedgehog anti-submarine mortar and depth charge rails aft and four side-mounted throwers.〔 River-class frigates were the first Royal Canadian Navy warships to carry the 147B Sword horizontal fan echo sonar transmitter in addition to the irregular ASDIC. This allowed the ship to maintain contact with targets even while firing unless a target was struck. Improved radar and direction-finding equipment improved the RCN's ability to find and track enemy submarines over the previous classes.〔 Canada originally ordered the construction of 33 frigates in October 1941.〔〔 The design was too big for the shipyards on the Great Lakes so all the frigates built in Canada were built in dockyards along the west coast or along the St. Lawrence River.〔 In all Canada ordered the construction of 60 frigates including ten for the Royal Navy that transferred two to the United States Navy.〔 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「HMCS Waskesiu (K330)」の詳細全文を読む スポンサード リンク
