The Wickes-class destroyers were a class of 111 destroyers built by the United States Navy in 1917–19. Along with the 6 preceding Caldwell-class and 156 subsequent Clemson-class destroyers, they formed the "flush-deck" or "four-stack" type. Only a few were completed in time to serve in World War I, including USS Wickes, the lead ship of the class.
HMS A5 was an early Royal Navy submarine. She was a member of Group Two of the first British A class of submarines. Like all members of her class, she was built at Vickers Barrow-in-Furness.
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 J-class submarines were seven submarines developed by the Royal Navy prior to the First World War in response to claims that Germany was developing submarines that were fast enough to operate alongside surface fleets. Six were completed during mid-1916, while a seventh entered service at the end of 1917.
Holland 1 is the first submarine commissioned by the Royal Navy. The first in a six-boat batch of the Holland-class submarine, she was lost in 1913 while under tow to be scrapped following her decommissioning. Recovered in 1982, she was put on display at the Royal Navy Submarine Museum, Gosport. Her battery bank found in the boat was discovered to be functional after being cleaned and recharged.
The Royal Navy's G class of diesel/electric submarines were launched between 1914 and 1917, and intended for operations in the North Sea and German Bight in World War I against German U-boats.
HMS Laforey was the lead ship of her class of destroyer built for the Royal Navy. Launched a year before the First World War began, she was attached to the Dover Patrol. Laforey saw action in several engagements with German torpedo boats, including the Battle off Noordhinder Bank and the action of 17 March 1917. Laforey was sunk in 1917 by a British mine after escorting several freighters to France. She was named for Francis Laforey, captain of HMS Spartiate at the Battle of Trafalgar in 1805.
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 F-class submarine was built for the Royal Navy as a coastal submarine based on the doubled hulled V-class submarine with very few minor improvements. The only important improvement was the addition of a stern torpedo tube. The F class were ordered as a successor to the E-class submarine, but only three were built out of the ten ordered, the first F1 at Chatham.
HMS L5 was a L-class submarine built for the Royal Navy during World War I. The boat survived the war and was sold for scrap in 1931.
HMS H24 was a British H-class submarine built by Vickers Limited, Barrow-in-Furness, as part of the Batch 3 H-class submarines. She was launched on 14 November 1917 and was commissioned on 30 April 1918.
HMS Arabis was an Arabis-class sloop of the Royal Navy. She had a brief career, serving during the First World War.
The Type U 66 was a class of five submarines or U-boats operated by the German Imperial Navy during World War I. The class is alternately referred to as the U-66-class or the Type UD. The class was built by Germaniawerft of Kiel to their 506d design as the U-7-class for the Austro-Hungarian Navy. The five boats were sold to the Imperial Germany Navy at the beginning of World War I when it was thought impossible for the submarines to reach the Mediterranean for delivery to Austria-Hungary.
The U-20 class was a class of four submarines or U-boats built for and operated by the Austro-Hungarian Navy during World War I. The class is sometimes referred to as the Havmanden class because it was based upon the design of the Royal Danish Navy's 1911 Havmanden-class submarines, three of which were built in Fiume.
HMS Ophelia was an Admiralty M-class destroyer built for the Royal Navy during the First World War, entering service in 1916. The ship served at the Battle of Jutland on 31 May/1 June 1916, and sank a German submarine in 1918. She was sold for scrap in 1921.
The Astraea class was an eight ship class of protected cruisers built for the Royal Navy during the 1890s. The ships served on a number of foreign stations during their careers, particularly in the waters of the Indian and Pacific Oceans, and around the Cape of Good Hope. Already obsolete by the outbreak of the First World War, most continued to see service in a variety of roles, though rarely in a front line capacity. By the end of the war the majority were being used as training or depot ships, and they were soon sold out of the service and scrapped. However, one ship, HMS Hermione, was bought by the Marine Society and used as a training ship until 1940.
HMS Pasley was an Admiralty M-class destroyer built on the Tyne by Swan Hunter & Wigham Richardson for the Royal Navy and launched on 15 April 1916. She saw service during the First World War.
HMS Rosalind was an R-class destroyer which served with the Royal Navy. The ship was launched by Thornycroft on 14 October 1916 as the first of five similar ships ordered from the yard. The design was used as the basis for five subsequent ships of the S-class also built by the company. Rosalind served as part of the Grand Fleet during the First World War, operating as an escort to other warships and in anti-submarine patrols alongside other destroyers. The vessel was sold to be broken up on 13 July 1926.
HMS Alyssum was an Arabis-class minesweeping sloop of the British Royal Navy which served during the First World War. Alyssum was built in 1915 by Earle's Shipbuilding, and was used for minesweeping, escort and patrol duties in the North and Irish Seas. The sloop sank after hitting a German mine on 18 March 1917.
