HMS Ostrich (1900)
HMS ''Ostrich'' was a Fairfield three-funnel, 30-knot torpedo boat destroyer ordered by the Royal Navy under the 1898 – 1899 Naval Estimates. In 1913 she was grouped as a C-class destroyer. She was the first Royal Navy ship to carry this name.Jane 1898, pp. 84–85.Moore 1990, p. 76. She spent most of her operational career in home waters, operating with the Channel Fleet as part of the Portsmouth Instructional Flotilla, and was sold for breaking in 1920. Construction and description On 30 March 1899, the British Admiralty placed an order with the shipbuilder Fairfield Shipbuilding and Engineering Company for two "Thirty-Knotter" torpedo-boat destroyers, and ''Ostrich''.Lyon 2001, pp. 23–24.Lyon 2001, p. 89. As with other early Royal Navy destroyers, the design of ''Ostrich'' was left to the builder, with the Admiralty laying down only broad requirements.Chesneau and Kolesnik 1979, p. 87.Manning 1961, p. 39.

Naval Ensign Of The United Kingdom
The White Ensign, at one time called the St George's Ensign due to the simultaneous existence of a cross-less 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. The White Ensign is also worn by yachts of members of the Royal Yacht Squadron and by ships of Trinity House escorting the reigning monarch. In addition to the United Kingdom, several other nations have variants of the White Ensign with their own national flags in the canton, with the St George's Cross sometimes being replaced by a naval badge omitting the cross altogether. Yachts of the Royal Irish Yacht Club wear a white ensign with an Irish tricolour in the first quadrant and defaced by the crowned harp from the Heraldic Badge of Ireland. The Flag of the British Antarctic Territory and the Commissioners' flag of the Northern Lighthouse Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

8th Destroyer Flotilla
The 8th Destroyer Flotilla, also styled as the Eighth Destroyer Flotilla, was a military formation of the British Royal Navy from 1911 to 1939. History The flotilla was established in August 1911. In 1912 was assigned to the Admiral of Patrols command and was based at Chatham Dockyard. For the duration World War I it was on patrol duties. Post first world war it was transferred to the Mediterranean Fleet from 1921 to 1924. In 1925 it was reassigned to the China Station where it remained just before the Second World War World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposin ... in May 1939 when it was renamed 21st Destroyer Flotilla.

HMNB Chatham
Chatham Dockyard was a Royal Navy Dockyard located on the River Medway in Kent. Established in Chatham in the mid-16th century, the dockyard subsequently expanded into neighbouring Gillingham (at its most extensive, in the early 20th century, two-thirds of the dockyard lay in Gillingham, one-third in Chatham). It came into existence at the time when, following the Reformation, relations with the Catholic countries of Europe had worsened, leading to a requirement for additional defences. Over 414 years Chatham Royal Dockyard provided more than 500 ships for the Royal Navy, and was at the forefront of shipbuilding, industrial and architectural technology. At its height, it employed over 10,000 skilled artisans and covered . Chatham dockyard closed in 1984, and of the Georgian dockyard is now managed as the Chatham Historic Dockyard visitor attraction by the Chatham Historic Dockyard Trust.

HMS Decoy (1894)
HMS ''Decoy'' was a torpedo boat destroyer which served with the Royal Navy in home waters. She was launched in 1895 and sunk in a collision with the destroyer in 1904. Construction She was built by John I. Thornycroft & Company at Chiswick and was launched on 7 February 1894.''The Times (London)'', Thursday, 8 February 1894, p.4 Although fitted with multiple torpedo tubes, her bow tube proved useless in practice as — while running at high attack speeds — the ship was prone to overtake its own torpedo. The clumsy tube also reduced living quarters and made the bridge very prone to flooding. Service ''Decoy'' took part in the 1896 British Naval Manoeuvres, attached to the Channel Fleet operation from Berehaven in southern Ireland.Brassey (1897), pp. 141–143, 149. She served as instructional tender to ''Cambridge'', a gunnery school ship, until August 1901. Lieutenant Cyril Asser was appointed in command in February 1902, when she was based at Plymouth as part of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Lively (1900)
HMS ''Lively'' was a torpedo boat destroyer of the British Royal Navy. She was built speculatively by Laird, Son & Company, Birkenhead, pre-empting further orders for vessels of this type, and was bought by the navy in 1901. Construction On 30 March 1899, the British Admiralty placed an order for two torpedo boat destroyers, ''Lively'' and , with the Birkenhead shipyard of Laird, Son & Co, as part of a total of twelve destroyers ordered under the 1899–1900 shipbuilding programme. These two ships were four-funneled and were similar to those ordered from Laird's under the 1894–1895 programme (the ), the 1895–1896 programme (the ) and the 1897–1898 programme (). ''Lively'' was long overall and between perpendiculars, with a beam of and a draught of . Displacement was light and full load. ''Lively'' was propelled by two triple expansion steam engines, fed by four Normand boilers, rated at to give the contract speed of 30 knots. Armament was the standard for t ...

Channel Fleet
The Channel Fleet and originally known as the Channel Squadron was the Royal Navy formation of warships that defended the waters of the English Channel from 1854 to 1909 and 1914 to 1915. History Throughout the course of Royal Navy's history there had been different squadrons stationed in home waters. One of the earliest known naval formations to be based at Plymouth was called the Western Squadron which was the forerunner of the Channel Squadron that was later known as the Channel Fleet. In 1650 Captain William Penn, Commander-in-Chief, was charged with guarding the Channel from Beachy Head to Lands End with six ships. This system continued following the Restoration. It was the start of what was to become a Western Squadron. From 1690 the squadron operated out of Plymouth Dockyard during wartime periods, which was for most of the 18th century and early 19th century. In 1854 The Channel Squadron, sometimes known as the Particular Service Squadron, was established. The Channel Squ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMNB Devonport
His Majesty's Naval Base, Devonport (HMNB Devonport) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Portsmouth) and is the sole nuclear repair and refuelling facility for the Royal Navy. The largest naval base in Western Europe, HMNB Devonport is located in Devonport, in the west of the city of Plymouth, England. The base began as Royal Navy Dockyard in the late 17th century, but shipbuilding ceased at Devonport in the early 1970s, although ship maintenance work has continued. The now privatised maintenance facilities are operated by Babcock International Group, who took over the previous owner Devonport Management Limited (DML) in 2007. DML had been running the Dockyard since privatisation in 1987. From 1934 until the early 21st century the naval barracks on the site was named HMS ''Drake'' (it had previously been known as HMS ''Vivid'' after the base ship of the same name).

Conning Tower
A conning tower is a raised platform on a ship or submarine, often armored, from which an officer in charge can conn the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield just enough personnel and devices for navigation during battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Steam Engine
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines. History The first commercially successful steam engine was developed by Thomas Newcomen in 1712. The steam engine improvements brought forth by James Watt in the later half of the 18th century greatly improved steam engine efficiency and allowed more compact engine arrangements. Successful adaptation of the steam engine to marine applications in England would have to wait until almost a century after Newcomen, when Scottish engineer William Symington built the world's "first practical steamboat", the '' Charlotte Dundas'', in 1802.

Thornycroft Boiler
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler. The fundamental characteristic of the "three-drum" design is the arrangement of a steam drum above two water drums, in a triangular layout. Water tubes fill in the two sides of this triangle between the drums, and the furnace is in the centre. The whole assembly is then enclosed in a casing, leading to the exhaust flue. Firing can be by either coal or oil. Many coal-fired boilers used multiple firedoors and teams of stokers, often from both ends. Development Development of the three-drum boiler began in the late 19th century, with the demand from naval ships that required high power and a compact boiler. The move to water-tube boilers had already begun, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...
