The '''''Black Swan'' class''' and '''Modified ''Black Swan'' class''' were two [[ship class|classes]] of [[sloop-of-war|sloop]] of the [[Royal Navy]] and [[Royal Indian Navy]].  Twelve ''Black Swan''s were launched between 1939 and 1943, including four for the Royal Indian Navy; twenty-five Modified ''Black Swan''s were launched between 1942 and 1945, including two for the Royal Indian Navy; several other ships were cancelled.

==History==
Like [[corvette]]s, sloops of that period were specialised [[convoy]]-defence vessels. Corvettes were based on a mercantile design with triple expansion engines, sloops were conventional naval vessels with turbines.  Sloops were larger and faster with a heavy armament of high angle 4-inch guns which had superior [[anti-aircraft warfare|anti-aircraft]] fire control via the [[Fuze Keeping Clock]], while retaining excellent [[anti-submarine warfare|anti-submarine]] capability. They were designed to have a longer range than a [[destroyer]] at the expense of a lower top speed, while remaining capable of outrunning surfaced [[German Type VII submarine|Type VII]] and [[German Type IX submarine|Type IX]] [[U-boat]]s.

In [[World War II]], ''Black Swan''-class sloops sank 29 U-boats. The most famous sloop commander was Captain [[Frederic John Walker]]. His sloop {{HMS|Starling|U66|2}} became one of the most successful submarine hunters, taking part in the sinking of eleven U-boats. After the war, sloops continued in service with the Royal Navy, [[Egyptian Navy]], [[Indian Navy]], [[Pakistan Navy]] and the [[German Navy|West German Navy]]. In April 1949, {{HMS|Amethyst|U16|2}} was attacked on the [[Yangtze River]] by the Communist [[People's Liberation Army]]. Several ''Black Swan'' sloops fought in the [[Korean War]].

==''Black Swan'' class==

===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.

===Royal Indian Navy===
Two ships were ordered under the 1939 Programme, the order being placed with Denny on 8&nbsp;September 1939. The second pair were ordered under the 1940 Programme, this order with Thornycroft being placed on 29&nbsp;August 1940. The first two were used as survey ships after the War. The second pair were transferred to the [[Pakistan Navy]] in 1948. The third pair (which were of the Modified ''Black Swan'' class – see below)

==Modified ''Black Swan'' class==

===Royal Navy===
Fourteen sloops for the RN were in the 1940 Supplementary War Programme. The first two were ordered from Denny, Dunbarton, on 9&nbsp;January 1941, ten more were ordered on 27&nbsp;March 1941 (two each from Cammell Laird, Scotts, Thornycroft, Yarrow and John Brown), and a final pair from Fairfield, Govan, on 18&nbsp;July 1941. The contract with John Brown was transferred to [[HMNB Devonport|Devonport Dockyard]] on 3&nbsp;March 1942, and then to Denny on 8&nbsp;December 1942.

Another fourteen ships were authorised in the 1941 Programme, but the last three ships (the names ''Star'', ''Steady'' and ''Trial'' had been approved) were not ordered under this programme. The first of the eleven actually ordered was contracted with Thornycroft on 3&nbsp;December 1941, with a further pair from Stephens, Linthouse, on 18 December. Eight more were ordered in 1942, two on 11 February, two on 3 March (originally from Portsmouth Dockyard), two on 12 August and two on 5 October. However the order for two sloops were ordered at Portsmouth was moved to Chatham Dockyard on 21&nbsp;June 1943, and they were laid down there, but were cancelled on 15&nbsp;October 1945.

Two more sloops were authorised in the 1942 Programme; the names would have been ''Waterhen'' and ''Wryneck'' but they were never ordered in that year's Programme. The 1944 Programme re-instated these two vessels, as well as the twelfth sloop authorised under the 1941 Programme, and now named as ''Partridge''. These three ships were ordered on 9&nbsp;October 1944, but they were all cancelled on 15&nbsp;October 1945. These had been intended to be further modified and enlarged, with a beam of {{Convert|38|ft|6|in}}. Two further ships planned under the 1944 Programme would have been named ''Woodpecker'' (ii) and ''Wild Swan'', but these were never ordered and the intention to build was dropped when the 1945 Programme was compiled.
* {{HMS|Partridge|U37|2}}, ordered from Thornycroft.
* {{HMS|Waterhen|U05|2}}, ordered from Denny.
* {{HMS|Wryneck|U31|2}}, ordered from Denny.

===Royal Indian Navy===
Two ships for the Indian Navy were included in the 1941 Programme, the order being placed with Yarrow on 10&nbsp;September 1941.
