Havock Class Destroyer
The ''Havock'' class was a class of torpedo boat destroyer (TBD) of the British Royal Navy. The two ships, and , built in London in 1893 by Yarrow & Company, were the first TBDs to be completed for the Royal Navy, although the equivalent pair from J.I. Thornycroft, and , were ordered five days earlier. Background The invention of the self-propelled torpedo by Robert Whitehead and Austrian Navy Captain Giovanni Luppis in 1866, combined with the introduction of small fast torpedo boats posed a threat to battleships: large numbers of torpedo boats could overwhelm a battleship's defences and sink it, or distract the battleship and make it vulnerable to opposing capital ships. Torpedo boats proved devastatingly effective in the 1891 Chilean Civil War. The defence against torpedo boats was clear: small warships accompanying the fleet that could screen and protect it from attack by torpedo boats. Several European navies developed vessels variously known as torpedo boat "catchers", ...

HMS Havock (1893)
HMS ''Havock'' was a torpedo boat destroyer of the British Royal Navy built by the Yarrow shipyard. She was one of the first destroyers ordered by the Royal Navy, and the first to be delivered. Design and construction ''Havock'' had a full load displacement of 275 tons and a speed of . She differed from her sister ship in having 2 locomotive boilers placed end-to-end, while ''Hornet'' had 8 water tube boilers. This resulted in an obvious external difference, since ''Hornet'' had 4 funnels (with the centre pair close together) while ''Havock'' had 2 closely spaced funnels. She was launched on 12 August 1893. Armament ''Havock'' was armed with a single 12-pounder gun mounted on a pedestal at the conning position, an exposed location that was extremely wet in even moderately rough weather. Three 6 pounder QF guns were mounted, with two either side of, and slightly abaft of, the conning position, and the third placed near the stern just aft of the torpedo tubes. Three 18-in ...

Battleship
A battleship is a large armored warship with a main battery consisting of large caliber guns. It dominated naval warfare in the late 19th and early 20th centuries. The term ''battleship'' came into use in the late 1880s to describe a type of ironclad warship,Stoll, J. ''Steaming in the Dark?'', Journal of Conflict Resolution Vol. 36 No. 2, June 1992. now referred to by historians as pre-dreadnought battleships. In 1906, the commissioning of into the United Kingdom's Royal Navy heralded a revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS ''Dreadnought'', were referred to as "dreadnoughts", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships were a symbol of naval dominance and national might, and for decades the battleship was a major factor in both diplomacy and military strategy.Sondhaus, L. ''Naval Warfare 1815–1914'', . A global arms race in battleship cons ...

Russian Destroyer Sokol (1895)
''Sokol'' (Russian: Сокол - Falcon) was the first torpedo boat destroyer built for the Imperial Russian Navy. She was designed and built by the British shipbuilder Yarrows from 1894 to 1895 and was claimed to be the fastest warship in the world during her sea trials. She was renamed ''Pruitki'' (Russian: Прыткий - Nimble) in 1902. The destroyer served as part of the Russian Baltic Fleet, taking part in the First World War and joined the Bolshevik Red Fleet following the October Revolution. She was active during the Russian Civil War and was scrapped in 1922. Design and construction The Imperial Russian Navy was the second navy, after the British Royal Navy, to order destroyers, placing an order with the British shipbuilder Yarrow & Company, a specialist in torpedo craft, which had built five of the Royal Navy's first destroyers (the and classes). Yarrow's design was similar to its designs for the Royal Navy, but the ship's hull made widespread use of nickel steel ...

Forecastle
The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters. Related to the latter meaning is the phrase " before the mast" which denotes anything related to ordinary sailors, as opposed to a ship's officers. History and design In medieval shipbuilding, a ship of war was usually equipped with a tall, multi-deck castle-like structure in the bow of the ship. It served as a platform for archers to shoot down on enemy ships, or as a defensive stronghold if the ship were boarded. A similar but usually much larger structure, called the aftcastle, was at the aft end of the ship, often stretching all the way from the main mast to the stern. Having such tall upper works on the ship was detrimental to sailing performance. As cannons were introduced and gunfire replaced boarding as the primary means of naval combat during the 16th century, the medieval ...

Water Tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ...

Cammell Laird
Cammell Laird is a British shipbuilding company. It was formed from the merger of Laird Brothers of Birkenhead and Johnson Cammell & Co of Sheffield at the turn of the twentieth century. The company also built railway rolling stock until 1929, when that side of the business was separated and became part of the Metro-Cammell, Metropolitan-Cammell Carriage & Wagon Company. History Formation from merger of Laird Company and Cammell & Co. The Laird Company was founded by William Laird (shipbuilder), William Laird, who had established the Birkenhead Iron Works in 1824. When he was joined by his son, John Laird (shipbuilder), John Laird in 1828, their first ship was an iron barge. John realised that the techniques of making boilers could be applied to making ships. The company soon became pre-eminent in the manufacture of iron ships and also made major advances in propulsion. In 1860, John Laird was joined in the business by his three sons, renaming the company John Laird, Sons & Co ...

Daring Class Destroyer (1893)
Two ''Daring''-class destroyers were the very first torpedo boat destroyers ("TBDs") to be ordered for the Royal Navy, the order being placed on 27 June 1892. Background The invention of the self-propelled torpedo by Robert Whitehead and Austrian Navy Captain Giovanni Luppis in 1866, combined with the introduction of small fast torpedo boats posed a threat to battleships: large numbers of torpedo boats could overwhelm a battleship's defences and sink it, or distract the battleship and make it vulnerable to opposing capital ships. Torpedo boats proved devastatingly effective in the 1891 Chilean Civil War. The defence against torpedo boats was clear: small warships accompanying the fleet that could screen and protect it from attack by torpedo boats. Several European navies developed vessels variously known as torpedo boat "catchers", "hunters" and "destroyers", while the Royal Navy itself operated torpedo gunboats. However, the early designs lacked the range and speed to keep ...

British Ordnance Terms
This article explains terms used for the British Armed Forces' ordnance (i.e.: weapons) and also ammunition. The terms may have slightly different meanings in the military of other countries. BD Between decks: applies to a naval gun mounting in which part of the rotating mass is below the deck, and part of it is above the deck. This allows for a lower profile of turret, meaning that turrets need not be superfiring (i.e. they can be mounted on the same deck and not obstruct each other at high angles of elevation.) BL The term BL, in its general sense, stood for breech loading, and contrasted with muzzle loading. The shell was loaded via the breech (i.e. the gunner's end of the barrel, which opened) followed by the propellant charge, and the breech mechanism was closed to seal the chamber. Breech loading, in its formal British ordnance sense, served to identify the gun as the type of rifled breechloading gun for which the powder charge was loaded in a silk or cloth bag and the br ...

John Fisher, 1st Baron Fisher
John Arbuthnot Fisher, 1st Baron Fisher, (25 January 1841 – 10 July 1920), commonly known as Jacky or Jackie Fisher, was a British Admiral of the Fleet. With more than sixty years in the Royal Navy, his efforts to reform the service helped to usher in an era of modernisation which saw the supersession of wooden sailing ships armed with muzzleloader, muzzle-loading cannon by steel-hulled battlecruisers, submarines and the first aircraft carriers. Fisher has a reputation as an innovator, strategist and developer of the navy rather than as a seagoing admiral involved in major battles, although in his career he experienced all these things. When appointed First Sea Lord in 1904 he removed 150 ships then on active service which were no longer useful and set about constructing modern replacements, developing a modern fleet prepared to meet German Empire, Germany during the First World War. Fisher saw the need to improve the range, accuracy and rate-of-fire of naval gunnery, and be ...

Rear Admiral
Rear admiral is a senior naval flag officer rank, equivalent to a major general and air vice marshal and above that of a commodore and captain, but below that of a vice admiral. It is regarded as a two star "admiral" rank. It is often regarded as a two-star rank with a NATO code of OF-7. The term originated in the days of naval sailing squadrons and can trace its origins to the Royal Navy. Each naval squadron was assigned an admiral as its head, who commanded from the centre vessel and directed the squadron's activities. The admiral would in turn be assisted by a vice admiral, who commanded the lead ships that bore the brunt of a battle. In the rear of the squadron, a third admiral commanded the remaining ships and, as this section was considered to be in the least danger, the admiral in command of it was typically the most junior. This has continued into the modern age, with rear admiral the most junior admiralty of many navies. In most European navies, the equivalent rank i ...
