Editing Black Swan-class sloop (section)

===Royal Navy===
The first two ships were built under the 1937 Programme, being ordered from [[Yarrow Shipbuilders|Yarrow and Company]], Scotstoun, on 1 January 1938. The second pair was built under the 1939 Programme, being ordered from [[Furness Shipbuilding Company]] on 21 June 1939.<ref name="hague p6,76">{{Harvard citation no brackets|Hague|1993|pp=6, 76}}</ref> A further ten RN ships were ordered under the 1940 War Programme on 13 April 1940; however six of these (the orders placed with White of Cowes, Thornycroft at Woolston, and Swan Hunter on Tyneside for two ships each) were subsequently replaced by orders for an equal number of {{sclass2|Hunt|destroyer|0}} escort destroyers.

There were incremental improvements as the building developed, and the ''Woodcock'' and ''Wren'' when completed were practically indistinguishable from the Modified ''Black Swan'' class.
