 {|    |} the isles-class trawlers were a class of naval trawler used by the royal navy, royal canadian navy and royal new zealand navy during world war ii. the type comprised 197 vessels built between 1939 and 1945 in the nearly identical isles, dance, tree and shakespearian classes. generally similar to the castle class naval trawlers of 1916-18, though somewhat larger, they were mainly used on minesweeping and harbour defence duties. most were armed with one 12-pounder gun and three or four 20 mm oerlikon aa guns with 30 depth charges. in the dance class a 4-inch aa gun was fitted in place of the 12-pdr, and there were six 20&nbsp;mm oerlikons in annet, bressay, damsay, fiaray, foulness and lindisfarne. four of the trawlers were given 'bird' names when converted to controlled minelayers in 1943-44: blackbird (m15), dabchick (m22), stonechat (m25) and whitethroat (m03). a total of 23 of these trawlers were lost during the war.robert gardiner (ed. dir.), conway's all the world's fighting ships 1922-1946, p. 66. london: conway maritime press, 1980. six trawlers were loaned to canada in 1942-45 and five to norway in 1943-45. postwar, 17 of the trawlers were disarmed as wreck disposal vessels: bardsey (dv13), bern (dv4), caldy (dv5) coll (dv6), earraid (dv7), fetlar (dv8), flatholm (dv9), graemsay (dv10), lindisfarne (dv11), lundy (dv12), neave (dv14), scalpay (dv15), skomer (dv16), '
