Sloops, what were the functions of the warship class described as sloops, before and during World War Two. A sloop was an escort vessel designed for convoy protection. The Royal Navy had been building types of convoy escorts classified as sloops before the advent of World War Two. "Sloops, Escort Vessels, Etc – Although not attracting great attention these vessels are some of the most vital in a fleet. It is extremely difficult to choose or plan the ideal craft for convoy escort, as so much depends upon the forces with which they are likely to be opposed. Fast craft such as sloops may be satisfactory against defense against submarines, but if large cruisers or even fast battleships may be encountered, the escort must be similarly strong.:" All the World’s Fighting Fleets Fifth Edition (1939) by E.C.Talbot-Booth. In 1937 a new class of sloop was introduced, the Black Swan Class, designed from the start as a warship for the express mission of convoy escort.
During World War Two the Royal Navy needed every escort it could find in her desperate effort to defend against the German U-Boat campaign. Numbers in vast quantities mattered more than the individual qualities of the class. A number of different types served as convoy escort. The all had the same mission but they all had their own strengths and weaknesses.

As can be seen the sloop, the DE and large corvette merged as a type to be called the frigate.
The Black Swan Class was the earliest of the classes and was one of the most successful types of escorts during the war. The 1937 requirements were for an ocean going escort with good AA and ASW qualities. Designed as a warship, they took two years to build and only yards with warship construction experience could build them. As the war progressed and new ASW systems were introduced, the Black Swan Class could not incorporate the new systems without landing some of its strong DP gun armament. The Royal Navy did not want to do this, as the extremely strong AA capability was still very much required. Britain built 31 of the class, subdivided into Black Swan (9 vessels) and Modified Black Swan (22 vessels) classes. Six more were built for India (4 & 2). The Modified Black Swan originally had better light AA and other improvements but by the end of the war but by the end of the war, there was very little difference between the two sub-types.

By the end of 1943, although U-Boats were still a threat, the Battle of the Atlantic had decisively swung in favor of the allies. As numbers of more capable ASW platforms were available, more and more of the Black Swans were sent to India to join the British Pacific Fleet, where their very strong AA capability was greatly needed. Of the 31 built for the RN, 17 were with the British Pacific Fleet and 6 had been lost by the end of the war. To keep an edge on their AA strengths, the class was consistently upgraded during the war in radar fits. After the war some of the ships were modified for peace time duties and the class continued to serve until the mid-1950s.
The Wild Goose was a member of the original Black Swan sub-type. Called the Mad Duck by her crew, she had a very active career during the war. She was substantially modified by removal of X gun mounting where an additional accommodation was installed. A lattice mast replaced the tripod and she was repainted with the white hull and buff funnel of the pre-war Far East scheme. She was assigned to the Persian Gulf Division of the East Indies Station where she served until 1954 when she was placed in reserve. Wild Goose was sold for scrapping in 1956.

Among the others in the class, there were a number that had interesting post war careers. Amethyst was trapped up the Yangtse River at Nanking in late 1949, 200 miles from the sea, when the Communist Chinese forces were victorious over the Nationalist Chinese forces. Heavily shelled, she made a nighttime dash down the river and reached the sea in an exploit later made into a movie. During the Korean War Black Swan was involved in a rare naval action in which five of the six attacking North Korean gunboats were sunk. Three were involved in the "Haifa Patrol" in an unsuccessful attempt to prevent the flow of Jewish refugees and armament into the Palestine and then the newly independent Israel. In the South Atlantic Snipe had a run-in with an Argentine gunboat as she was re-establishing British posts on King George Island in the South Shetlands. Perhaps the oddest fate awaited Mermaid, Flamingo, Hart and Acteon. In 1958/59, they were transferred to the newly reformed Federal German Navy. They were renamed Scharnhorst, Graf Spee, Scheer and Hipper, where they served as training vessels until the early 1970s. How ironic that these humble sloops, designed with an eye on the rapidly expanding German Navy before World War Two, should end up carrying the distinguished names of a German battleship and heavy cruisers.

Resin Casting
The Wild Goose also comes with castings for five deckhouses or platforms. All are very well done with quite a number of fittings cast integral to the individual parts. The level of detail on these smaller parts is fully the equal to that found in the hull casting. The single stack has steam pipes and a lot of detail as part of this very small part, although the upper stack platform is a trifle on the thick side. Other even smaller resin parts include two platforms, ships boats, ventilators and aft lattice stump main mast. This last part is necessarily solid and would be better represented as the open lattice by photo-etch. It should not be too hard to find a PE part that is adaptable for this structure, although I have yet to check for such a piece.
