Parker Class Leader
The ''Parker''-class leaders or improved ''Marksman''-class leaders were a class of six destroyer leaders built for the Royal Navy during 1916–17 for World War I service. They were named after famed historical naval leaders, except for ''Anzac'', which was named to honour the Australian and New Zealand Army Corps, and was later transferred to the Royal Australian Navy. They were the last major Royal Navy warships to be ordered with three propeller shafts, a design that was never widely adopted in British warships. Design The ''Parker''s were based on the design of the preceding leaders and shared the same hull design and dimensions. Operations with the ''Marksman'' class and previous leaders indicated several areas for improvement: more freeboard, increased firepower, and relocation of the bridge to a position further aft. On the ''Parker'' class, the bridge was moved aft by reducing the boiler rooms from three to two; instead of the four funnels on the ''Marksman''s, the ''P ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freeboard (nautical)
In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. In commercial vessels, the latter criterion measured relative to the ship's load line, regardless of deck arrangements, is the mandated and regulated meaning. In yachts, a low freeboard is often found on racing boats, for increased speed (by reducing weight and therefore drag). A higher freeboard will give more room in the cabin, but will increase weight and drag, compromising speed. A higher freeboard, such as used on ocean liners, also helps weather waves and so reduce the likelihood of being washed over by full water waves. A low-freeboard vessel is susceptible to taking in water in rough seas. Freighter ships and warships use high freeboard designs to increase internal volume, which also allows them to satisfy International Maritime Organization (IMO) damage stability regulations, due to in ...

Destroyer Classes
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumbarton
Dumbarton (; also sco, Dumbairton; ) is a town in West Dunbartonshire, Scotland, on the north bank of the River Clyde where the River Leven flows into the Clyde estuary. In 2006, it had an estimated population of 19,990. Dumbarton was the capital of the ancient Kingdom of Strathclyde, and later the county town of Dunbartonshire. Dumbarton Castle, on top of Dumbarton Rock, dominates the area. Dumbarton was a Royal burgh between 1222 and 1975. Dumbarton emerged from the 19th century as a centre for shipbuilding, glassmaking, and whisky production. However these industries have since declined, and Dumbarton today is increasingly a commuter town for Glasgow east-southeast of it. Dumbarton F.C. is the local football club. Dumbarton is home to BBC Scotland's drama studio. History Dumbarton history goes back at least as far as the Iron Age and probably much earlier. It has been suggested that in Ancient Rome, Roman times Dumbarton was the "place of importance" named as Alauna in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Saumarez, 1st Baron De Saumarez
Admiral of the Red James Saumarez, 1st Baron de Saumarez (or Sausmarez), Order of the Bath, GCB (11 March 1757 – 9 October 1836) was an admiral of the British Royal Navy, known for his victory at the Second Battle of Algeciras. Early life Saumarez was born at St Peter Port, Guernsey to an old island family, the eldest son of Matthew de Sausmarez (1718-1778) and his second wife Carteret, daughter of James Le Marchant. He was a nephew of Captain Philip Saumarez and John de Sausmarez (1706-1774) of Sausmarez Manor. He was also the elder brother of General (United Kingdom), General Sir Thomas Saumarez (1760-1845), Equerry and Groom of the Chamber to the Prince Edward, Duke of Kent and Strathearn, Duke of Kent, and afterwards Commander-in-Chief of New Brunswick and of Richard Saumarez (1764-1835), a surgeon and medical author. Their sister married Henry Brock, the uncle of Major-General Sir Isaac Brock and Daniel de Lisle Brock. Many of de Sausmarez's ancestors had distinguished ...

Shetland Islands
Shetland, also called the Shetland Islands and formerly Zetland, is a subarctic archipelago in Scotland lying between Orkney, the Faroe Islands and Norway. It is the northernmost region of the United Kingdom. The islands lie about to the northeast of Orkney, from mainland Scotland and west of Norway. They form part of the border between the Atlantic Ocean to the west and the North Sea to the east. Their total area is ,Shetland Islands Council (2012) p. 4 and the population totalled 22,920 in 2019. The islands comprise the Shetland constituency of the Scottish Parliament. The local authority, the Shetland Islands Council, is one of the 32 council areas of Scotland. The islands' administrative centre and only burgh is Lerwick, which has been the capital of Shetland since 1708, before which time the capital was Scalloway. The archipelago has an oceanic climate, complex geology, rugged coastline, and many low, rolling hills. The largest island, known as " the Mainland", ha ...

William Hoste
Captain Sir William Hoste, 1st Baronet KCB RN (26 August 17806 December 1828) was a Royal Navy captain. Best known as one of Lord Nelson's protégés, Hoste was one of the great frigate captains of the Napoleonic wars, taking part in six major actions including the capture of the heavily fortified port of Kotor. He was, however, absent from Trafalgar having been sent with gifts to the Dey of Algiers. Childhood and education He was the second of eight children of Reverend Dixon Hoste (1750–1805) and Margaret Stanforth. At the time of his birth his father was rector of Godwick and Tittleshall in Norfolk. He was born at Ingoldisthorpe, and the family later moved to Godwick Hall, east of Tittleshall, which was leased from Thomas Coke, who later became the 1st Earl of Leicester, of Holkham Hall. His next brother, George Charles Hoste, became an officer in the Royal Engineers. Hoste was educated for a time at King's Lynn and later at the Paston School in North Walsham, where Ho ...

Richard Grenville
Sir Richard Grenville (15 June 1542 – 10 September 1591), also spelt Greynvile, Greeneville, and Greenfield, was an English privateer and explorer. Grenville was lord of the manors of Stowe, Cornwall and Bideford, Devon. He subsequently participated in the plantations of Ireland, the English colonisation of the Americas and the repulse of the Spanish Armada. Grenville also served as Member of Parliament for Cornwall, High Sheriff for County Cork and Sheriff of Cornwall. In 1591, Grenville died at the battle of Flores fighting against an overwhelmingly larger Spanish fleet near the Azores. He and his crew on board the galleon fought against the 53-strong Spanish fleet to allow the other English ships to escape. Grenville was the grandfather of Sir Bevil Grenville, a prominent military officer during the English Civil War. Origins Richard Grenville was the eldest son and heir of Sir Roger Grenville (d. 1545), who was captain of when it sank in Portsmouth Harbour in 15 ...

Birkenhead
Birkenhead (; cy, Penbedw) is a town in the Metropolitan Borough of Wirral, Merseyside, England; historically, it was part of Cheshire until 1974. The town is on the Wirral Peninsula, along the south bank of the River Mersey, opposite Liverpool. At the 2011 census, it had a population of 88,818. Birkenhead Priory and the Mersey Ferry were established in the 12th century. In the 19th century, Birkenhead expanded greatly as a consequence of the Industrial Revolution. Birkenhead Park and Hamilton Square were laid out as well as the first street tramway in Britain. The Mersey Railway connected Birkenhead and Liverpool with the world's first tunnel beneath a tidal estuary; the shipbuilding firm Cammell Laird and a seaport were established. In the second half of the 20th century, the town suffered a significant period of decline, with containerisation causing a reduction in port activity. The Wirral Waters development is planned to regenerate much of the dockland. Toponymy The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Laying
A gun is a ranged weapon designed to use a shooting tube (gun barrel) to launch projectiles. The projectiles are typically solid, but can also be pressurized liquid (e.g. in water guns/cannons, spray guns for painting or pressure washing, projected water disruptors, and technically also flamethrowers), gas (e.g. light-gas gun) or even charged particles (e.g. plasma gun). Solid projectiles may be free-flying (as with bullets and artillery shells) or tethered (as with Taser guns, spearguns and harpoon guns). A large-caliber gun is also called a ''cannon''. The means of projectile propulsion vary according to designs, but are traditionally effected pneumatically by a high gas pressure contained within the barrel tube, produced either through the rapid exothermic combustion of propellants (as with firearms), or by mechanical compression (as with air guns). The high-pressure gas is introduced behind the projectile, pushing and accelerating it down the length of the tube ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Director (military)
A director, also called an auxiliary predictor, is a mechanical or electronic computer that continuously calculates trigonometric firing solutions for use against a moving target, and transmits targeting data to direct the weapon firing crew. Naval warships For warships of the 20th century, the director is part of the fire control system; it passes information to the computer that calculates range and elevation for the guns. Typically, positions on the ship measured range and bearing of the target; these instantaneous measurements are used to calculate rate of change values, and the computer ("fire control table" in Royal Navy terms) then predicts the correct firing solution, taking into account other parameters, such as wind direction, air temperature, and ballistic factors for the guns. The British Royal Navy widely deployed the Pollen and Dreyer Fire Control Tables during the First World War, while in World War II a widely used computer in the US Navy was the electro-mechanical ...

Fo'c'sle
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 ...
