HMS ''Griffin'' (H31) was a G-class destroyer, built for the Royal Navy in the mid-1930s. In World War II she took part in the Norwegian Campaign of April–May 1940 and the Battle of Dakar in September before being transferred to the Mediterranean Fleet in November. She generally escorted larger ships of the Mediterranean Fleet as they protected convoys against attacks from the Italian Fleet. ''Griffin'' took part in the Battle of Cape Matapan in March 1941 and the evacuations of Greece and Crete in April–May 1941. In June she took part in the Syria-Lebanon Campaign and was escorting convoys and the larger ships of the Mediterranean Fleet until she was transferred to the Eastern Fleet in March 1942. ''Griffin'' saw no action in the Japanese Indian Ocean raid in April, but was escorting convoys for most of her time in the Indian Ocean. In June she returned to the Mediterranean to escort another convoy to Malta in Operation Vigorous. Beginning in November 1942, she was converted to an escort destroyer in the United Kingdom and was transferred to the Royal Canadian Navy on 1 March 1943. The ship, now renamed HMCS ''Ottawa'', was assigned to escort convoys in the North Atlantic until she was transferred in May 1944 to protect the forces involved with the Normandy Landings. Working with other destroyers, ''Ottawa'' sank three German submarines off the French coast before she returned to Canada for a lengthy refit. After the end of the European war in May 1945 she was used to bring Canadian troops until she was paid off in October 1945. ''Ottawa'' was sold for scrap in August 1946. ==Description== ''Griffin'' displaced at standard load and at deep load. She had an overall length of , a beam of and a draught of .

Her complement was 137 officers and men in peacetime,〔Whitley, pp. 107–08〕 but in increased to 146 in wartime.〔English, p. 89〕 The ship mounted four 45-calibre 4.7-inch (120 mm) Mark IX guns in single mounts. For anti-aircraft (AA) defence, ''Griffin'' had two quadruple Mark I mounts for the 0.5 inch Vickers Mark III machine gun. She was fitted with two above-water quadruple torpedo tube mounts for torpedoes.〔 One depth charge rail and two throwers were fitted; 20 depth charges were originally carried, but this increased to 35 shortly after the war began.〔English, p. 141〕 Beginning in mid-1940, her anti-aircraft armament was increased although when exactly the modifications were made is not known. The rear set of torpedo tubes was replaced by a AA gun and the quadruple .50-calibre Vickers mounts were replaced by autocannon. Two more Oerlikon guns were also added in the forward superstructure.〔 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「HMS Griffin (H31)」の詳細全文を読む スポンサード リンク
