In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
The Flower-class corvette was a British class of 294 corvettes used during World War II, specifically with the Allied navies as anti-submarine convoy escorts during the Battle of the Atlantic. Royal Navy ships of this class were named after flowers, hence the name of the class.
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 Shoreham-class sloops were a class of eight warships of the Royal Navy built in the early 1930s.
The Banff-class sloop was a group of ten warships of the Royal Navy. Built as United States Coast Guard Lake-class cutters, in 1941 these ships were loaned to the Royal Navy as antisubmarine warfare escort ships. The transfers took place at the Brooklyn Navy Yard; the sloops were manned for transport to Britain by personnel from the damaged battleship Malaya which was under repair there.
HMS President is a "stone frigate", or shore establishment of the Royal Naval Reserve, based on the northern bank of the River Thames near Tower Bridge in Wapping and is in the London Borough of Tower Hamlets.
The Cadmus class was a six-ship class of 10-gun screw steel sloops built for the Royal Navy between 1900 and 1903. This was the last class of the Victorian Navy's multitude of sloops, gunvessels and gunboats to be constructed, and they followed the traditional pattern for 'colonial' small warships, with a full rig of sails. After them, the "Fisher Reforms" of the Navy ended the construction and deployment of this type of vessel. Most of the class survived until the 1920s, remaining on colonial stations during World War I.
