HMS Cavalier
HMS ''Cavalier'' is a retired destroyer of the Royal Navy. She was laid down by J. Samuel White and Company at East Cowes on 28 March 1943, launched on 7 April 1944, and commissioned on 22 November 1944. She served in World War II and in various commissions in the Far East until she was decommissioned in 1972. After decommissioning she was preserved as a museum ship and currently resides at Chatham Historic Dockyard. Construction ''Cavalier'' was one of 96 War Emergency Programme destroyers ordered between 1940 and 1942. She was one of the first ships to be built with the forward and aft portions of her hull welded, with the midsection riveted to ensure strength. The new process gave the ship additional speed. In 1970 a 64-mile race was arranged between ''Cavalier'' and the frigate , which had the same hull form and machinery. ''Cavalier'' beat ''Rapid'' by after ''Rapid'' lifted a safety valve, reaching an average speed of . Service history After commissioning she joined the ...

Chatham Dockyard
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.

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. 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 superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Honour
A battle honour is an award of a right by a government or sovereign to a military unit to emblazon the name of a battle or operation on its flags ("colours"), uniforms or other accessories where ornamentation is possible. In European military tradition, military units may be acknowledged for their achievements in specific wars or operations of a military campaign. In Great Britain and those countries of the Commonwealth which share a common military legacy with the British, battle honours are awarded to selected military units as official acknowledgement for their achievements in specific wars or operations of a military campaign. These honours usually take the form of a place and a date (e.g. "Cambrai 1917"). Theatre honours, a type of recognition in the British tradition closely allied to battle honours, were introduced to honour units which provided sterling service in a campaign but were not part of specific battles for which separate battle honours were awarded. Theatre h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
U-boat
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Home Fleet
The Home Fleet was a fleet of the Royal Navy that operated from the United Kingdom's territorial waters from 1902 with intervals until 1967. In 1967, it was merged with the Mediterranean Fleet creating the new Western Fleet. Before the First World War, it consisted of the four Port Guard ships. In 1905 it was disestablished, and from 1905 to 1907 remaining ships at a lesser state of readiness were split into the reserve divisions (Devonport Division, Nore Division, and Portsmouth Division). During the First World War, it comprised some of the older ships of the Royal Navy. During the Second World War, it was the Royal Navy's main battle force in European waters. Pre-First World War In the first years of the 20th century, the Royal Navy had four 'Port Guard' ships, stationed in the major naval bases, partially to act as flagships for the admirals commanding at those ports. These vessels appear to have been stationed at the Nore, Portsmouth, and Plymouth, as well as one other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
6th Destroyer Flotilla
The British 6th Destroyer Flotilla, or Sixth Destroyer Flotilla, was a military formation of the Royal Navy from 1911 to 1939 and again from 1947 to 1951 History The flotilla was formed in 1911 at Portsmouth, with its first commander, Captain Mortimer Silver, being appointed in 1912. During World War 1 it was based at Dover, forming the fighting nucleus of the Dover Patrol commanded by Rear-Admiral Reginald Bacon. From June 1915 it consisted of 11 Tribal-class destroyers, 13 other destroyers capable of 30 knots, and 4 Cricket-class destroyers along with , the flagship of Captain Charles Johnson.

Safety Valve
A safety valve is a valve that acts as a fail-safe. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would be a rupture disk. Safety valves were first developed for use on steam boilers during the Industrial Revolution. Early boilers operating without them were prone to explosion unless carefully operated. Vacuum safety valves (or combined pressure/vacuum safety valves) are used to prevent a tank from collapsing while it is being emptied, or when cold rinse water is used after hot CIP (clean-in-place) or SIP (sterilization-in-place) procedures. When sizing a vacuum safety valve, the calculation method is not defined in any norm, particularly in the hot CIP / cold water scenario, but some manu ...

Rivet
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the ''tail''. On installation, the rivet is placed in a punched or drilled hole, and the tail is ''upset'', or ''bucked'' (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the original head is called the ''factory head'' and the deformed end is called the ''shop head'' or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support tension loads. However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional w ...

War Emergency Programme Destroyers
The War Emergency Programme destroyers were destroyers built for the British Royal Navy during World War I and World War II. World War I emergency programmes The 323 destroyers ordered during the First World War belonged to several different classes and were the subject of 14 separate War Programmes between 1914 and 1918. 40 of these were cancelled at the end of the war. The total excludes destroyers building in UK for other navies which were purchased for the Royal Navy following the outbreak of war. World War II emergency programme The 112 destroyers built during the Second World War were based on the hull and machinery of the earlier J-, K- and N-class destroyers of the 1930s. Each of the fourteen flotillas produced consisted of eight destroyers. Due to supply problems and the persistent failure by the Royal Navy to develop a suitable dual-purpose weapon for destroyers, they were fitted with whatever armament was available. Advances in radar and weaponry were incorporated as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
