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.
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.
The twenty-eight Anchusa-class sloops were built under the Emergency War Programme for the Royal Navy in World War I as the final part of the larger "Flower class", which were also referred to as the "Cabbage class", or "Herbaceous Borders".
HMS President (1918) is a retired Flower-class Q-ship that was launched in 1918. She was renamed HMS President in 1922 and moored permanently on the Thames as a Royal Navy Reserve drill ship. In 1982 she was sold to private owners and, having changed hands twice, served as a venue for conferences and functions as well as the offices for a number of media companies. She has been moved to Chatham on the Medway in Kent since 2016, but is due to return to the capital. She had the suffix "(1918)" added to her name in order to distinguish her from HMS President, the Royal Naval Reserve base in St Katharine Docks. She is one of the last three surviving Royal Navy warships of the First World War. She is also the sole representative of the first type of purpose built anti-submarine vessels, and is the ancestor of World War II convoy escort sloops, which evolved into modern anti-submarine frigates.
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.
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.
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.
The C-class submarines were five United States Navy submarines built by the Fore River Shipbuilding Company in Quincy, Massachusetts, under a subcontract from the Electric Boat Company. Built between 1906 and 1909, and in commission from 1908 to 1919, all five were subsequently sold for scrap in 1920. They were considerably larger than the preceding B class at 275 tons submerged vs. 173 tons submerged, and were the first United States submarines with two-shaft propulsion, doubling the machinery of the B class.
The Dance class of World War II were armed trawlers of the Royal Navy. They were used for anti-submarine (A/S) and minesweeping work and were nearly identical to the Isles class, of which they are usually considered a subclass.
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 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, but they were not named Racehorse class as the Admiralty realised that this could easily be confused in communications with the Racecourse class of paddle minesweepers, and they officially became the 24 class.
The Shakespearian-class trawler was a series of anti-submarine naval trawlers of the Royal Navy. Ships in the class had a displacement of 545 long tons (554 t), a top speed of 12 knots and a crew of 40 men. The trawlers were armed with a QF 12-pounder [76 mm (3.0 in)] gun, three 20 mm Oerlikon anti-aircraft guns and thirty depth charges. The class was nearly identical to the Isles-class trawlers, of which they are usually considered a subclass. Coriolanus, Horatio and Laertes were lost during the war. Othello, was transferred to Italy in 1946 and Rosalind to Kenya, also in 1946. By the end of that year, only Hamlet and Macbeth remained in service with the Royal Navy; both were sold in 1947.
Tree-class trawlers were a class of anti-submarine naval trawlers which served in the Royal Navy during the Second World War. They were nearly identical to the Isles-class trawlers, of which they are usually considered a subclass.
USS Remlik (SP-157) was a yacht acquired by the U.S. Navy during World War I. She was converted into an armed patrol craft and assigned to protect ships from German submarines in the North Atlantic Ocean. Post-war she was decommissioned, stripped of naval ordnance and sold in Norfolk, Virginia.
HMS Vetch (K132) was a Flower-class corvette that served in the Royal Navy during the Second World War. After helping to escort many convoys and sinking two U-boats, she was decommissioned and sold in 1945.
SS Ardena was a minesweeper and escort vessel built as an Azalea-class sloop minesweeper for the British Royal Navy with the name HMS Peony in 1915.
HMS Kilbride was a sloop of the Kil class which were also referred to as gunboats, built for the Royal Navy during the First World War. It was designed for anti-submarine warfare, but was completed too late in the war to be used extensively in that role. The class were designed to be double-ended to confuse submarine observers, and were painted in dazzle camouflage.
HMS Zinnia was an Azalea-class minesweeping sloop of the Royal Navy, built in 1915 at the Swan Hunter & Wigham Richardson yard, at Wallsend in the United Kingdom.It was sold to Belgium on 19 April 1920 to join their new Corps of Destroyers and Sailors.
