QF 4 Inch Naval Gun Mk IV, XII, XXII
The QF 4-inch gun Mk IVMk IV = Mark 4. Britain used Roman numerals to denote Marks (models) of ordnance until after World War II. This was the fourth model of 4-inch QF naval gun. Variants Mk XII = Mark 12, Mk XXII = Mark 22. was the main gun on most Royal Navy and British Empire destroyers in World War I. It was introduced in 1911 as a faster-loading light gun successor to the BL 4 inch Mk VIII gun. Of the 1,141 produced, 939 were still available in 1939.Campbell, ''Naval Weapons of WWII'', p.59. Mk XII and Mk XXII variants armed many British interwar and World War II submarines. Mk IV gun Mk IV armed many British destroyers and some cruisers in World War I. It was used to arm merchant ships in World War II. The guns armed the following warships : * ''Forward''-class scout cruisers as re-gunned in 1911 * ''Sentinel''-class scout cruisers as re-gunned 1911-1912 * ''Pathfinder''-class scout cruisers as re-gunned 1911-1912 * ''Adventure''-class scout cruisers as re-gunned 19 ...

Imperial War Museum
Imperial War Museums (IWM) is a British national museum organisation with branches at five locations in England, three of which are in London. Founded as the Imperial War Museum in 1917, the museum was intended to record the civil and military war effort and sacrifice of Britain and British Empire, its Empire during the First World War. The museum's remit has since expanded to include all conflicts in which British or Commonwealth forces have been involved since 1914. As of 2012, the museum aims "to provide for, and to encourage, the study and understanding of the history of modern war and 'wartime experience'." Originally housed in the Crystal Palace at Sydenham Hill, the museum opened to the public in 1920. In 1924, the museum moved to space in the Imperial Institute in South Kensington, and finally in 1936, the museum acquired a permanent home that was previously the Bethlem Royal Hospital in Southwark. The outbreak of the Second World War saw the museum expand both its coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pathfinder-class Cruiser
The ''Pathfinder''-class cruisers were a pair of scout cruisers built for the Royal Navy in the first decade of the 20th century. The sister ships spent much of the first decade of their careers in reserve. When the First World War began in August 1914 they were given coastal defence missions, on the coast of Scotland and on the coast of Yorkshire. The latter ship was badly damaged when the Germans bombarded Hartlepool in December. She spent the rest of the war in British waters. The ship was paid off in 1919 and sold for scrap the following year. ''Pathfinder'' was sunk by a German submarine shortly after the war began, the first sinking of a British warship during the war by a German submarine. Background and description In 1901–1902, the Admiralty developed scout cruisers to work with destroyer flotillas, leading their torpedo attacks and backing them up when attacked by other destroyers. In May 1902, it requested tenders for a design that was capable of , a protective ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Falkland
East Falkland ( es, Isla Soledad) is the largest island of the Falklands in the South Atlantic, having an area of or 54% of the total area of the Falklands. The island consists of two main land masses, of which the more southerly is known as Lafonia; it is joined by a narrow isthmus where the settlement of Goose Green is located, and it was the scene of the Battle of Goose Green during the Falklands War. The two main centres of population in the Falklands, Stanley and Mount Pleasant, which are both in the northern half of East Falkland, are home to three-quarters of the island's population. Geography East Falkland, which has an area of , a little over half the total area of the islands consists of two land masses of approximately equal size. The island is almost bisected by two deep fjords, Choiseul Sound and Brenton Loch-Grantham Sound which are separated by the wide isthmus that connects Lafonia in the south to the northern part of East Falkland. The island's coastline h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S-class Destroyer (1917)
The S class (initially known as the Modified ''Trenchant'' classMarch, ''op. cit.'' p.215.) was a class of 67 destroyers ordered for the Royal Navy in 1917 under the 11th and 12th Emergency War Programmes. They saw active service in the last months of the First World War and in the Russian and Irish Civil Wars during the early 1920s. Most were relegated to the reserve by the mid-1920s and subsequently scrapped under the terms of the London Naval Treaty. Eleven survivors saw much action during the Second World War. Background In early 1917, the First World War had been going on for two and a half years. Despite the disappointing outcome of the Battle of Jutland the previous year, the British Grand Fleet, consisting of battleships, cruisers, and destroyers and based in northern Scotland, was successfully confining the German surface navy to the German Bight, while enforcing a blockade of German maritime trade with the wider world. In southern North Sea, the Harwich Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
R-class Destroyer (1916)
The first R class were a class of 62 destroyers built between 1916 and 1917 for the Royal Navy. They were an improvement, specifically in the area of fuel economy, of the earlier destroyers. The most important difference was that the Admiralty R class had two shafts and geared turbines, compared with the three shafts and direct turbines of the Admiralty M class, but in appearance the R class could be distinguished from its predecessors by having the after 4-inch gun mounted in a bandstand. The Admiralty ordered the first two of this class of ships in May 1915. Another seventeen were ordered in July 1915, a further eight in December 1915, and a final twenty-three in March 1916 (of which eleven were to a slightly modified design). As well as these fifty ships to the standard 'Admiralty' design, twelve more R class were designed and built by the two specialist builders Yarrow Shipbuilders and John I. Thornycroft & Company to their own separate designs. Three were ordered from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yarrow Later M-class Destroyer
The Yarrow Later M class were a class of seven destroyers built for the Royal Navy that saw service during World War I. They were based on the preceding and successful Yarrow M class with minor alterations; notably reduced beam to compensate for increased displacement and a sloping stern. They were sometimes described as the Yarrow R class of destroyers. Ships Four vessels were ordered in July 1915: * – Laid down August 1915, launched 24 July 1916, completed September 1916. Sold for breaking up 5 November 1926. * – Launched 30 September 1916 and completed late 1916. Sunk by gunfire from German cruisers ''Bremse'' and off Norway, 17 October 1917. * – Launched 25 November 1916 and completed 1916, torpedoed and sunk by German U-boat off Maas light ship on night of 22 December/23 December 1917. * – Laid down August 1915, launched 5 February 1917, completed February 1917. Sold for breaking up 5 November 1926. Three vessels were ordered in March 1916: * – Laid down ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Faulknor-class Flotilla Leader
The ''Faulknor'' class were a class of flotilla leaders that were under construction in the United Kingdom for the Chilean Navy at the outbreak of World War I. Six ships were ordered by Chile, of which the first two (''Almirante Lynch'' and ''Almirante Condell'') were delivered to Chile before the outbreak of the war. The remaining four ships were purchased by the British, taken over and completed for the Royal Navy for wartime service. In common with Royal Navy convention, they were named after famous Royal Navy captains of the past, in this case the members of the Faulknor family. Design The six s were a private design by J. Samuel White that were significantly larger and heavier armed than their contemporaries. They had four funnels, a tall, narrow fore funnel and three broad, short funnels behind. They were initially armed with six single QF 4-inch guns, unusually arranged with four on the forecastle - two sited in front of the wheelhouse and two sited abreast it - the ...

Hawthorn M-class Destroyer
The Hawthorn M (or Mansfield) Class were a class of two destroyers built for the Royal Navy under the pre-war 1913-14 Programme for World War I service. They were similar to the Admiralty M class, but completed to a modified design by Hawthorn Leslie and Company, Hebburn on Tyne. They had four funnels instead of the three funnels of the Admiralty design; as a consequence, they were the last four-funnelled destroyers (apart from Leaders) to be built for the Royal Navy. The midships 4 inch gun was shipped between the second and third funnels. Both ships were laid down on 9 July 1914 and completed in 1915. Both survived the war and were scrapped in 1921, Hawthorn Leslie subsequently received orders for two further M class destroyers as part of the large batch of orders placed in May 1915, but these two - ''Pidgeon'' and ''Plover'' - were built to the Admiralty M class design. Ships * , launched 21 August 1914, completed January 1915, sold for breaking up 9 May 1921 to Thos. W. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thornycroft M-class Destroyer
The Thornycroft M or ''Mastiff'' class were a class of six British destroyers completed for the Royal Navy during 1914–16 for World War I service. They were quite different from the Admiralty-designed ships of the , although based on a basic sketch layout provided by the British Admiralty from which J I Thornycroft developed their own design. Like the 'standard' Admiralty M class they had three funnels, but the centre funnel was thicker in the Thornycroft ships. The midships gun was shipped between the second and third funnels. ''Patriot'' was fitted to carry a kite balloon. Ships Two ships were ordered (contracted) on 1 February 1913, two more on 26 February 1915 and the last two on 15 May 1915. * ''Meteor'' – laid down 8 May 1913, launched 24 July 1914, completed 15 September 1914. Sold for breaking up 9 May 1921. * ''Mastiff'' – laid down 10 July 1913, launched 5 September 1914, completed 12 November 1914. Sold for breaking up 9 May 1921. * ''Patrician'' – laid down ...

Admiralty M-class Destroyer
The M class, more properly known as the Admiralty M class, were a class of 85 destroyers built for the Royal Navy of United Kingdom that saw service during World War I. All ships were built to an identical – Admiralty – design, hence the class name. 18 other vessels which were officially included within the 'M' class were built to variant designs by three specialist builders – 10 by Yarrow, 6 by Thornycroft (who also built another 6 to the standard Admiralty design), and 2 by Hawthorn Leslie; these are covered in other articles. The Admiralty design was based on the preceding L class but modified to produce an increase in speed by approximately . All ships built to the Admiralty design had three identical narrow, circular funnels (this did not apply to the 18 ships built by the specialist yards). Ships of the pre-war (1913–14) Programme Six vessels were built under the 1913–14 Naval Programme. These differed from the wartime vessels by being 1,010 tons full load, with ...

Yarrow M-class Destroyer
The Yarrow M class was a class of ten destroyers built for the Royal Navy that saw service during World War I. They were generally similar to the standard , but were instead designed by the builder, Yarrow & Company. Generally, they had two instead of three shafts, as well as two funnels and a straight stern, with the bridge set well back from the forecastle. The first trio were two knots faster than the Admiralty M type, despite less installed power and one less shaft; the installed power was increased for the later vessels. ''Jane's Fighting Ships'' describes the class as "very successful boats", and all ten vessels survived throughout the war to be broken up during the 1920s. ''Moon'', ''Mounsey'' and ''Musketeer'' were each fitted to carry a kite balloon A kite balloon is a tethered balloon which is shaped to help make it stable in low and moderate winds and to increase its lift. It typically comprises a streamlined envelope with stabilising features and a harness or yoke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
