Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Fifth Rate
In the rating system of the Royal Navy used to categorise sailing warships, a fifth rate was the second-smallest class of warships in a hierarchical system of six " ratings" based on size and firepower. Rating The rating system in the Royal Navy as originally devised had just four rates, but early in the reign of Charles I, the original fourth rate (derived from the "Small Ships" category under his father, James I) was divided into new classifications of fourth, fifth, and sixth rates. While a fourth-rate ship was defined as a ship of the line, fifth and the smaller sixth-rate ships were never included among ships-of-the-line. Nevertheless, during the Anglo-Dutch Wars of the 17th century, fifth rates often found themselves involved among the battle fleet in major actions. Structurally, these were two-deckers, with a complete battery on the lower deck, and fewer guns on the upper deck (below the forecastle and quarter decks, usually with no guns in the waist on this deck). ...

Frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, what is now generally regarded as the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), a type of powerful ironclad warships was developed, and because they had a single gun deck, the term 'frigate' was used to describe them. Later developments in ironclad ships rendered the 'frigate' designation obsolete and the term fell out of favour. During the Second World War ...

Screw Frigate
Steam frigates (including screw frigates) and the smaller steam corvettes, steam sloops, steam gunboats and steam schooners, were steam-powered warships that were not meant to stand in the line of battle. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of screw-powered versions of the traditional frigates, corvettes, sloops and gunboats. Evolution First steam warships The first small vessel that can be considered a steam warship was the '' Demologos'', which was launched in 1815 for the United States Navy. From the early 1820s, the British Navy began building a number of small steam warships including the armed tugs and , and by the 1830s the navies of America, Russia and France were experimenting with steam-powered warships. Hellenic sloop-of-war '' Kartería'' (Καρτερία; Greek for "Perseverance") was the first steam-powered warship to be used in combat operations in history. It was built in 1825 in an Eng ...

A-class Destroyer (1929)
The A- and B-class destroyers were a group of 18 destroyers built for the Royal Navy during the late 1920s, with two additional ships built for the Royal Canadian Navy. The British ships were divided into two flotillas of eight destroyers, each with a flotilla leader. Design and description The A-class design was derived from the 1926 prototypes and for the 1927–28 Naval Construction Programme. The initial staff requirements were unrealistic and would have resulted in a much larger, unaffordable ship; they were scaled back, both to reduce the size of the ship and to save money. Nonetheless, the design had an improved gun armament, heavier torpedo armament, and greater range, at the cost of of speed, in comparison with the prototypes. The As were fitted with the Two-Speed Destroyer Sweep (TSDS) minesweeping gear and only had a residual anti-submarine ability while the Bs were equipped with Type 119 ASDIC (sonar) and had a full complement of depth charges, but could not us ...
