In the rating system of the Royal Navy used to categorise sailing warships, a first rate was the designation for the largest ships of the line. Originating in the Jacobean era with the designation of Ships Royal capable of carrying at least 400 men, the size and establishment of first-rates evolved over the following 250 years to eventually denote ships of the line carrying at least 80 guns across three gundecks. By the end of the eighteenth century, a first-rate carried no fewer than 100 guns and more than 850 crew, and had a measurement (burthen) tonnage of some 2,000 tons.
In British maritime law and custom, an ensign is the identifying flag flown to designate a British ship, either military or civilian. Such flags display the United Kingdom Union Flag in the canton, with either a red, white or blue field, dependent on whether the vessel is civilian, naval, or in a special category. These are known as the red, white, and blue ensigns respectively.
The White Ensign, at one time called the St George's Ensign because of the simultaneous existence of a crossless version of the flag, is an ensign worn on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field, identical to the flag of England except with the Union Flag in the upper canton.
Alfred was the merchant vessel Black Prince, named for Edward, the Black Prince, and launched in 1774. The Continental Navy of what would become the United States Navy acquired her in 1775, renamed her Alfred after 9th century English monarch Alfred the Great, and commissioned her as a warship. She participated in two major actions, the battle of Nassau, and the action of 6 April 1776. The Royal Navy captured her in 1778, took her into service as HMS Alfred, and sold her in 1782. She then became the merchantman Alfred, and sailed between London and Jamaica.
A gig is a type of boat. It was optimised for speed under oar, but usually also fitted with a sailing rig for appropriate conditions. The type was in use by Deal boatmen in the 18th century. It first occurred as a naval ship's boat after Deal boatbuilders recommended a different design to boats ordered from them by the Royal Navy to equip the cutters purchased in the 1760s to combat smuggling. The captains of larger warships soon sought permission to substitute a gig for one of the heavier boats which were then used; some even had a gig built at their own expense. The gig therefore became part of the usual complement of ship's boats used in warships.
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number. Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship.
Dazzle camouflage, also known as razzle dazzle or dazzle painting, is a family of ship camouflage that was used extensively in World War I, and to a lesser extent in World War II and afterwards. Credited to the British marine artist Norman Wilkinson, though with a rejected prior claim by the zoologist John Graham Kerr, it consisted of complex patterns of geometric shapes in contrasting colours interrupting and intersecting each other.
The Captain class was the designation given to 78 frigates of the Royal Navy, constructed in the United States, launched in 1942–1943 and delivered to the United Kingdom under the provisions of the Lend-Lease agreement. They were drawn from two classes of the American destroyer escort classification: 32 of the GMT (Evarts) Type and 46 of the TE (Buckley) Type. Upon reaching the UK the ships were substantially modified by the Royal Navy, making them distinct from the US Navy destroyer escort ships.
A funnel is the smokestack or chimney on a ship used to expel boiler steam and smoke or engine exhaust. They are also commonly referred to as stacks.
Buff is a light brownish yellow, ochreous colour, typical of buff leather. Buff is a mixture of yellow ochre and white: two parts of white lead and one part of yellow ochre produces a good buff, or white lead may be tinted with French ochre alone.
HMS Speedy was a 14-gun Speedy-class brig of the British Royal Navy. Built during the last years of the American War of Independence, she served with distinction during the French Revolutionary Wars.
HMS President 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.
A facing colour, also known as facings, is a common tailoring technique for European military uniforms where the visible inside lining of a standard military jacket, coat or tunic is of a different colour to that of the garment itself. The jacket lining evolved to be of different coloured material, then of specific hues. Accordingly, when the material was turned back on itself: the cuffs, lapels and tails of the jacket exposed the contrasting colours of the lining or facings, enabling ready visual distinction of different units: regiments, divisions or battalions each with their own specific and prominent colours. The use of distinctive facings for individual regiments was at its most popular in 18th century armies, but standardisation within infantry branches became more common during and after the Napoleonic Wars.
The air forces of the United Kingdom – the Royal Navy's Fleet Air Arm, the Army's Army Air Corps and the Royal Air Force use a roundel, a circular identification mark, painted on aircraft to identify them to other aircraft and ground forces. In one form or another, it has been used on British military aircraft from 1915 to the present.
Copper sheathing is a method for protecting the hull of a wooden vessel from attack by shipworm, barnacles and other marine growth through the use of copper plates affixed to the surface of the hull, below the waterline. It was pioneered and developed by the Royal Navy during the 18th century. In antiquity, ancient Greeks used lead plates to protect the underwater hull.
The Royal Corps of Naval Constructors (RCNC) is an institution of the British Royal Navy and Admiralty for training in naval architecture, marine, electrical and weapon engineering. It was established by Order in Council in August 1883, on the recommendation of the naval architect Sir William White. Its precursor was the Royal School of Naval Architecture, London.
Ship camouflage is a form of military deception in which a ship is painted in one or more colors in order to obscure or confuse an enemy's visual observation. Several types of marine camouflage have been used or prototyped: blending or crypsis, in which a paint scheme attempts to hide a ship from view; deception, in which a ship is made to look smaller or, as with the Q-ships, to mimic merchantmen; and dazzle, a chaotic paint scheme which tries to confuse any estimate of distance, direction, or heading. Counterillumination, to hide a darkened ship against the slightly brighter night sky, was trialled by the Royal Canadian Navy in diffused lighting camouflage.
HMS Victory is a 104-gun first-rate ship of the line of the Royal Navy. She was ordered in 1758, laid down in 1759, and launched in 1765. With 246 years of service as of 2024, she is the world's oldest naval vessel still in commission.
Admiralty tugs were tugboats built for and operated by the Royal Navy. These were vessels built to Admiralty specifications and in specific classes during the First and Second World Wars. They were built to meet the Royal Navy's demand for auxiliary vessels and to supplement the civilian tugs requisitioned by the Admiralty for war service.
In 1935, the United States Navy Naval Research Laboratory began studies and tests on low visibility ship camouflage. Research continued through World War II to (1) reduce visibility by painting vertical surfaces to harmonize with the horizon and horizontal surfaces to blend with the sea, or (2) confuse identity and course by painting obtrusive patterns on vertical surfaces. Some camouflage methods served both purposes. American captains were permitted less freedom of interpretation with these schemes than their British Commonwealth counterparts applied to Admiralty camouflage schemes.
