The 24 class was a class of minesweeping sloops. They were derived from the preceding Flower-class sloop, but designed to appear double-ended. Twenty-four ships to this design (hence the class name) were ordered between December 1916 and April 1917 under the Emergency War Programme for the Royal Navy in World War I, although two of them were cancelled before launch. All were named after famous racehorses (winners of The Derby), but they were not named Racehorse class as the Admiralty realised that this could easily be confused in communications with the Racecourseclass of paddle minesweepers, and they officially became the 24 class.

Contents

Like the Flower-class sloops, they were single-screw fleet sweeping sloops used almost entirely for minesweeping, although only ten were completed by the Armistice in 1918. However, they had identical deckhouses and gun shields at either end of the vessel, with straight stems and sterns. Furthermore, four of those completed had the single mast aft of the centrally-located funnel, and the rest had the mast forward of the funnel. The symmetrical design was completed with fake anchors at the stern to confuse enemy targeting.

The V and W class was an amalgam of six similar classes of destroyer built for the Royal Navy under the 9th, 10th, 13th and 14th of fourteen War Emergency Programmes during the First World War and generally treated as one class. For their time they were among the most powerful and advanced ships of their type in the world, and set the trend for future British designs.

Hunt-class minesweeper (1916)

The Hunt-class minesweeper was a class of minesweeping sloop built between 1916 and 1919 for the Royal Navy. They were built in two discrete groups, the earlier Belvoir group designed by the Ailsa Shipbuilding Company and the subsequent Aberdare group designed by the Admiralty. They were classed as Fleet Minesweeping Sloops, that is ships intended to clear open water. The Belvoir group were named after British fox hunts. Those of the Aberdare group were originally named after coastal towns, watering places and fishing ports, some of which happened to be hunts by coincidence. However, all were soon renamed after inland locations to prevent confusion caused by the misunderstanding of signals and orders.

Loch-class frigate WWII-era Royal Navy warship

The Loch class was a class of anti-submarine (A/S) frigate built for the Royal Navy and her Allies during World War II. They were an innovative design based on the experience of three years of fighting in the Battle of the Atlantic and attendant technological advances. Some shipyards had trouble building these larger ships, which led to widespread use of the Castle-class corvette, introduced around the same time.

Thornycroft type destroyer leader

The Thornycroft type leader or Shakespeare class were a class of five destroyer leaders designed by John I. Thornycroft & Company and built by them at Woolston, Southampton for the Royal Navy towards the end of World War I. They were named after historical naval leaders. Only Shakespeare and Spenser were completed in time for wartime service. The other three were completed after the war, Broke and Keppel after being towed to Royal dockyards for completion, and two further ships - Saunders and Spragge - were cancelled. The function of a leader was to carry the flag staff of a destroyer flotilla, therefore they were enlarged to carry additional crew, offices and signalling equipment, allowing a fifth gun to be carried. These ships were very similar to the Admiralty type leader, but had Thornycroft design characteristics, the most noticeable being the broad, slab-sided funnels.

<i>Arabis</i>-class sloop

The Arabis class was the third, and largest, of the five sub-classes of minesweeping sloops completed under the Emergency War Programme for the Royal Navy in World War I. They were part of the larger "Flower class" shipbuilding project, which were also referred to as the "Cabbage class", or "Herbaceous Borders". The ships were also used outside their minesweeping duties as patrol vessels, tugs, and personnel and cargo transports.

The Aubrietia-class sloops were a class of twelve sloops built under the Emergency War Programme for the Royal Navy in World War I as part of the larger Flower class. They were also referred to as the "cabbage class", or "herbaceous borders". The Flowers were the first ships designed as minesweepers.

<i>Acacia</i>-class sloop

The Acacia class was a class of twenty-four sloops that were ordered in January 1915 under the Emergency War Programme for the Royal Navy in World War I as part of the larger Flower class which were also referred to as the "Cabbage class", or "Herbaceous Borders". They were ordered in two batches, twelve ships on 1 January and another twelve on 12 January, and all were launched within about four or five months, and delivered between May and September 1915. They were used almost entirely for minesweeping until 1917, when they were transferred to escort duty.
