HMS Whirlwind (R87)
The second HMS ''Whirlwind'' was a W-class destroyer of the British Royal Navy and was built by Hawthorn Leslie and was launched on 30 August 1943. She saw service during World War II and the Cold War. Design and construction ''Whirlwind'' was one of eight W-class destroyers ordered as the 9th Emergency Flotilla on 3 December 1941. The W-class were War Emergency Programme destroyers, intended for general duties, including use as anti-submarine escort, and were to be suitable for mass-production. They were based on the hull and machinery of the pre-war J-class destroyers, but with a lighter armament (effectively whatever armament was available) in order to speed production. The W-class were almost identical to the U-class ordered as the 7th Emergency Flotilla and the V-class ordered as the 8th Emergency Flotilla earlier in the year, with the major difference the fitting of a new dual-purpose fire control director, capable of directing both anti-aircraft and anti-aircraf ...

Hawthorn Leslie
R. & W. Hawthorn, Leslie and Company, Limited, usually referred to as Hawthorn Leslie, was a shipbuilder and locomotive manufacturer. The company was founded on Tyneside in 1886 and ceased building ships in 1982. History The company was formed by the merger of the shipbuilder A. Leslie and Company in Hebburn with the locomotive works of R and W Hawthorn at St. Peter's in Newcastle upon Tyne in 1886. The company displaced its locomotive manufacturing interests in 1937 to Robert Stephenson and Company, which became ''Robert Stephenson and Hawthorns Ltd.'' Perhaps the most famous ship built by the Company was HMS ''Kelly'', launched in 1938 and commanded by Lord Louis Mountbatten. In 1954, the shipbuilding and marine engine activities were put into separate subsidiaries, Hawthorn Leslie (Shipbuilders) Ltd. and Hawthorn Leslie (Engineers) Ltd. In 1968 the Company's shipbuilding interests were merged with that of Swan Hunter and the Vickers Naval Yard to create Swan Hunter & Tyne ...

British 21-inch Torpedo
There have been several British 21-inch (533 mm) torpedoes used by the Royal Navy since their first development just before the First World War. Torpedoes of 21 inch calibre were the largest torpedoes in common use in the RN. They were used by surface ships and submarines rather than aircraft, which used smaller British 18-inch torpedo, 18-inch torpedoes. Mark I The first British 21-inch torpedo came in two lengths, "Short" at , and "Long" at . The explosive charge was of gun cotton increased later to . Mark II The Mark II, chiefly used by destroyers, entered service in 1914. Apart from some older British ships, it was used with the old US (destroyers-for-bases deal) Town-class destroyers provided to the UK during the early part of the Second World War. The running speed was reduced from (over 3,000 yards) for better reliability. The Mark II*, an improved Mark II, was used by battleships and battlecruisers. A wet heater design, it could run for at .

World War II
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 opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Naming And Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

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] |
United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

W And Z Class Destroyer
The W and Z class was a class of sixteen destroyers of the Royal Navy launched in 1943–1944. They were constructed as two flotillas, with names beginning with "W-" and "Z-", respectively, although, like the preceding , two of the flotilla leaders were named after historical naval figures (as had been Royal Navy practice during the inter-war years). They were known as the 9th and 10th Emergency Flotilla, respectively and served as fleet and convoy escorts in World War II. None were lost during World War II but INS ''Eilat'' (originally HMS ''Zealous'') was sunk during the Israel-Egypt conflict in October 1967 by Egyptian missile boats and the '' El Qaher'' (originally HMS ''Myngs'') of the Egyptian Navy was sunk at Berenice, Egypt on 16 May 1970 by Israeli Air Force aircraft during the War of Attrition. Design Repeats of the preceding U and V-class destroyers, with modified director structures. The Z class were armed with 4.5 inch guns.March, p.419. Ships W class ...

Limbo (weapon)
Limbo, or Anti Submarine Mortar Mark 10 (A/S Mk.10), was the final development of the forward-throwing anti-submarine weapon Squid, designed during the Second World War and was developed by the Admiralty Underwater Weapons Establishment in the 1950s. Limbo was installed on the quarterdeck of Royal Navy escort ships from 1955 to the mid-1980s, Australian–built destroyer and s. Limbo was widely employed by the Royal Canadian Navy, being incorporated into all destroyer designs from the late 1950s to the early 1970s, including the , , , and classes and the Type 12 President Class frigates built for the South African Navy in the 1960s. Operation Limbo was loaded and fired automatically with the crew under-cover and was stabilised in pitch and roll. The firing distance of the mortars was controlled by opening gas vents; rounds could be fired from . The weapon was linked to the sonar system of the ship, firing on command when the target was in range. The rounds were projected so t ...

Squid (weapon)
Squid was a British World War II ship-mounted anti-submarine weapon. It consisted of a three-barrelled mortar which launched depth charges. It replaced the Hedgehog system, and was in turn replaced by the Limbo system. Development Ordered directly from the drawing board in 1942, under the auspices of the Directorate of Miscellaneous Weapons Development, this weapon was rushed into service in May 1943 on board HMS ''Ambuscade''. The first production unit was installed on HMS ''Hadleigh Castle''; it went on to be installed on 70 frigates and corvettes during the Second World War. The first successful use was by HMS ''Loch Killin'' on 31 July 1944, when she sank . The system was credited with sinking 17 submarines in 50 attacks over the course of the war. By 1959, 195 Squid installations had been produced. This weapon was a three-barrel mortar with the mortars mounted in series but off-bore from each other in order to scatter the projectiles. The barrels were mounted in a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of World War II British Naval Radar
This page is a List of World War II British naval radar. Nomenclature These sets were initially numbered as wireless telegraph (w/t) sets, but a distinguishing prefix of "2" was soon added. Metric sets were numbered in the 28x and 29x series. When centimetric sets arrived with the advent of the cavity magnetron, they were numbered by subtracting 10 from the metric type number they were based on (e.g. the metric Type 284 was replaced by the centimetric Type 274). This was not always possible however, as Types 271 - 274 were already in use for original centimetric sets, thus some metric sets in the Type 28x range had 20 subtracted (e.g. the metric Type 282 was replaced by the centimetric Type 262). Aerial outfits were given a three letter identifier that began with "A". Suffixing letters indicated the following; * B - conversion of sets with separate transmitting (Tx) and receiving (Rx) antennas to single antenna operation. * M, P, Q - major set modifications * R - addition of ran ...

Type 277 Radar
The Type 277 was a surface search and secondary aircraft early warning radar used by the Royal Navy and allies during World War II and the post-war era. It was a major update of the earlier Type 271 radar, offering much more power, better signal processing, new displays, and new antennas with greatly improved performance and much simpler mounting requirements. It allowed a radar with performance formerly found only on cruisers and battleships to be fitted even to the smallest corvettes. It began to replace the 271 in 1943 and was widespread by the end of the year. The Type 271 was one of the first microwave frequency radars to enter service, when microwave electronics design was in its infancy. While it was still being fitted to escort ships during 1941 and 1942, great strides in technique were being made in cavity magnetron, waveguide, antenna design and general electronics. Those upgrades that could be easily combined with the existing systems became the 271 Mark IV models, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 293 Radar
The Type 293 radar was designed as a short-range aerial-search radar This is a list of different types of radar. Detection and search radars Search radars scan great volumes of space with pulses of short radio waves. They typically scan the volume two to four times a minute. The waves are usually less than a meter ... for surface ships in 1945. It used the same transmitter as the Type 277 surface-search radar, but used a new antenna design intended to cover the area above the ship to provide air warning instead of surface search. The stabilised "cheese" antenna, diameter in the AUR antenna, was upgraded to in Type 293P and to in the postwar Type 293Q.Friedman, p. 197 Specifications Notes Bibliography * *{{cite book, last=Watson, first=Raymond C.
