QF 6-inch Naval Gun
The QF 6-inch 40 calibre naval gun ( Quick-Firing) was used by many United Kingdom-built warships around the end of the 19th century and the start of the 20th century. In UK service it was known as the QF 6-inch Mk I, II, III guns.Mk I, II and III = Marks 1, 2 and 3. Britain used Roman numerals to denote Marks (models) of service ordnance until after the Second World War. This article describes the first three models of Royal Navy 6-inch QF guns. As the 15 cm/40 (6") 41st Year Type naval gun it was used for pre-dreadnought battleship Pre-dreadnought battleships were sea-going battleships built between the mid- to late- 1880s and 1905, before the launch of in 1906.

Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edgar-class Cruiser
The ''Edgar'' class was a nine-ship class of protected cruiser built around 1891 for the Royal Navy. Nine ships were completed, all of which participated in the First World War. One, , was lost during the war, with the other eight being scrapped in the 1920s. Design Armament for the majority of the class was two 9.2-inch guns one at each end of the ship on the centreline with ten 6-inch guns. Four of the 6-inch guns were in casemates on the main deck and six protected only by shields. For protection against torpedo boats there were 12 QF 6-pounder Hotchkiss guns and four QF 3-pounder Hotchkiss guns. Armament was completed with four 18-inch torpedo tubes. ''Edgar''-class ships main protection was a thick armoured deck starting at waterline level arching up over the machinery spaces. The gun casemates were thick, with shields for the 9.2 inch guns. The conning tower had armour. Four of the ''Edgar'' class were fitted with anti-torpedo bulge The anti-torpedo bulge (also ...

Powerful-class Cruiser
The ''Powerful'' class were a pair of first-class protected cruisers built for the Royal Navy (RN) in the 1890s, designed to hunt down enemy commerce raiders. Both ships served on the China Station and participated in the Second Boer War of 1899–1900. went on to help suppress the Boxer Rebellion a few months later. served as the flagship of the Australia Station in 1905–1912; shortly after her return home, she became a training ship and remained in that role until she was sold for scrap in 1929. ''Terrible'' was mostly in reserve after she returned home in 1902 and was often used as an accommodation ship. During the First World War she was disarmed and made one voyage as a troop transport in 1915. The ship became a depot ship when she returned home and then became a training ship in 1918. ''Terrible'' was sold for scrap in 1932. Background The impetus for the construction of the ''Powerful'' class began with the laying down the Russian armoured cruiser in 1890 that ...

Diadem-class Cruiser
The ''Diadem''-class cruiser was a class of "first class" protected cruiser built for the Royal Navy during the 1890s that served in the First World War. The class consisted of eight ships, built at a cost of around £600,000 each. They were considered "good sea boats" but criticised for their lack of a heavy calibre main armament, bulky unprotected sides, average speed and lack of manoeuvrability despite being considered large ships when completed. They were the last British first class protected cruisers; the armoured cruiser taking the large cruiser role in future." Design The ''Diadem''s were designed by Sir William White, and are typical of British design practice of the period, with high freeboard (by the standards of the time) and the use of 'double-decker' casemates, with the hull forward and aft cut away to allow fore and aft fire from the casemate guns. Casemates provided protection for the guns and allowed a large number of guns to bear on the broadside; however ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

6 Inch Gun From HMS Calypso Rear
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler".

Built-up Gun
A built-up gun is artillery with a specially reinforced barrel. An inner tube of metal stretches within its elastic limit under the pressure of confined powder gases to transmit stress to outer cylinders that are under tension.Fairfield (1921) p.161 Concentric metal cylinders or wire windings are assembled to minimize the weight required to resist the pressure of powder gases pushing a projectile out of the barrel. Built-up construction was the norm for guns mounted aboard 20th century dreadnoughts and contemporary railway guns, coastal artillery, and siege guns through World War II. Background The first built-up gun was designed by French artillery officer Alfred Thiéry in 1834 and tested not later than 1840. Also about 1840 another one was made by Daniel Treadwell, and yet another one was produced by Mersey Iron Works in Liverpool according to the John Ericsson's design. Sheffield architector John Frith received a patent on their manufacture in 1843. However, all these guns (w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
