picture info	British Empire The British Empire was composed of the dominions, colonies, protectorates, mandates, and other territories ruled or administered by the United Kingdom and its predecessor states. It began with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, of the world population at the time, and by 1920, it covered , of the Earth's total land area. As a result, its constitutional, legal, linguistic, and cultural legacy is widespread. At the peak of its power, it was described as "the empire on which the sun never sets", as the Sun was always shining on at least one of its territories. During the Age of Discovery in the 15th and 16th centuries, Portugal and Spain pioneered European exploration of the globe, and in the process established large overse ...

picture info	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]
picture info	British Ordnance Terms This article explains terms used for the British Armed Forces' ordnance (i.e.: weapons) and also ammunition. The terms may have slightly different meanings in the military of other countries. BD Between decks: applies to a naval gun mounting in which part of the rotating mass is below the deck, and part of it is above the deck. This allows for a lower profile of turret, meaning that turrets need not be superfiring (i.e. they can be mounted on the same deck and not obstruct each other at high angles of elevation.) BL The term BL, in its general sense, stood for breech loading, and contrasted with muzzle loading. The shell was loaded via the breech (i.e. the gunner's end of the barrel, which opened) followed by the propellant charge, and the breech mechanism was closed to seal the chamber. Breech loading, in its formal British ordnance sense, served to identify the gun as the type of rifled breechloading gun for which the powder charge was loaded in a silk or cloth bag and the br ...

picture info	Roman Numerals Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers are written with combinations of letters from the Latin alphabet, each letter with a fixed integer value, modern style uses only these seven: The use of Roman numerals continued long after the decline of the Roman Empire. From the 14th century on, Roman numerals began to be replaced by Arabic numerals; however, this process was gradual, and the use of Roman numerals persists in some applications to this day. One place they are often seen is on clock faces. For instance, on the clock of Big Ben (designed in 1852), the hours from 1 to 12 are written as: The notations and can be read as "one less than five" (4) and "one less than ten" (9), although there is a tradition favouring representation of "4" as "" on Roman numeral clocks. Other common uses include year numbers on monuments and buildings and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Anti-aircraft Warfare Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes Surface-to-air missile, surface based, subsurface (Submarine#Armament, submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defense, Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the World War II, Second World War, the Soviet Union, and modern NATO a ...

picture info	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]

picture info	HMS Adventure (M23) HMS ''Adventure'', pennant number M23, was an ''Adventure''-class minelaying cruiser of the Royal Navy built in the 1920s that saw service during the Second World War. Her commander between 1928 and 1929 was the future First Sea Lord John H. D. Cunningham. Laid down at Devonport in November 1922 and launched in June 1924, ''Adventure'' was the first vessel built for service as a minelayer; she was also the first warship to use diesel engines, which were used for cruising. ''Adventure'' first joined the Atlantic Fleet, then was transferred to the China Station in 1935. In World War II, the ship was damaged in 1941 and 1944, and was converted to a landing craft repair in 1944. In 1945 ''Adventure'' was reduced to reserve and in 1947 she was sold and broken up for scrap. Design ''Adventure'' was built to replace the converted First World War veteran ''Princess Margaret'', and her design was dictated by a requirement for a large mine capacity and a good cruising range. The min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Seaplane Tender A seaplane tender is a boat or ship that supports the operation of seaplanes. Some of these vessels, known as seaplane carriers, could not only carry seaplanes but also provided all the facilities needed for their operation; these ships are regarded by some as the first aircraft carriers and appeared just before the First World War. Terminology In maritime parlance a tender is a vessel that is used to support the operation of other vessels. In British usage, the term tender was used for small craft, with the term depot ship being used for large seagoing vessels. Flying boats and float planes even when based at home in ports and harbour had a need for small support vessels to operate.p British tenders were small craft of launch to pinnace size. These were used to ferry crews, stores and supplies between shore and the aircraft, to maintain the buoys used to mark out "taxiways" and "runways" and to keep these clear of debris to prevent foreign object damage, and in the case of ...

picture info	HMAS Albatross (1928) HMAS ''Albatross'' (later HMS ''Albatross'') was a seaplane tender of the Royal Australian Navy (RAN), which was later transferred to the Royal Navy and used as a repair ship. ''Albatross'' was built by Cockatoo Island Dockyard during the mid-1920s and entered service at the start of 1929. The ship experienced problems with the aircraft assigned to her during her career: the amphibious aircraft she had been designed for were retired just before the ship entered service, the replacement aircraft could not be catapult-launched from the ship, and a new plane designed specifically to work with the ship began operations after ''Albatross'' was demoted from seagoing status in 1933. After five years in reserve, ''Albatross'' was transferred to the Royal Navy to offset the Australian purchase of the light cruiser . Although the British had little use for a seaplane carrier, the ship found a niche after two aircraft carriers were sunk by the Germans early in World War II. ''Albatross' ...
