BL 16 Inch Mk I Naval Gun
The BL 16-inch Mark I was a British naval gun introduced in the 1920s and used on the two ''Nelson''-class battleships. A breech-loading gun, the barrel was 45 calibres long ("/45" in shorthand) meaning 45 times the bore – long. Description These wire-wound built-up guns had originally been planned for the cancelled G3-class battlecruiser design upon which the ''Nelson'' class drew. Sir W. G. Armstrong Whitworth & Company at Elswick, Vickers at Barrow-in-Furness, William Beardmore & Company at Dalmuir and the Royal Gun Factory at Woolwich made a total of 29 guns of which 18 would be required for both ships at any time. These guns broke with the example offered by the earlier 15-inch Mk I gun, which fired a heavy shell at a rather low muzzle velocity, and instead fired a rather light shell at a high muzzle velocity; this was not a success, as at the initial muzzle velocity the gun wore down rapidly and the accuracy was unsatisfactory, so much that it was lowered. ...

Royal Arsenal
The Royal Arsenal, Woolwich is an establishment on the south bank of the River Thames in Woolwich in south-east London, England, that was used for the manufacture of armaments and ammunition, proofing, and explosives research for the British armed forces. It was originally known as the Woolwich Warren, having begun on land previously used as a domestic warren in the grounds of a Tudor house, Tower Place. Much of the initial history of the site is linked with that of the Office of Ordnance, which purchased the Warren in the late 17th century in order to expand an earlier base at Gun Wharf in Woolwich Dockyard. Over the next two centuries, as operations grew and innovations were pursued, the site expanded massively. At the time of the First World War the Arsenal covered and employed close to 80,000 people. Thereafter its operations were scaled down. It finally closed as a factory in 1967 and the Ministry of Defence moved out in 1994. Today the area, so long a secret enclave ...

Naval Guns Of The United Kingdom
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broa ...

World War II Naval Weapons Of The United Kingdom
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
16"/45 Caliber Gun
The 16"/45 caliber gun (spoken "sixteen-inch-forty-five-caliber") was used for the main batteries of the last class of Standard-type battleships for the United States Navy, the . These guns promised twice the muzzle energy over the Mark 7 12-inch/50 caliber guns of the and a 50% increase over the 14-inch/45 caliber guns of the , , and s. Design The 16-inch gun was a built-up gun constructed in a length of 45 calibers. The Mark 1 had an A tube, jacket, liner, and seven hoops, four locking rings and a screw-box liner. When the gun was designed in August 1913 it was referred to as the "Type Gun (45 Cal.)" as an effort to conceal the gun's true size of 16 inches. Gun No. 1, the prototype, was proof fired in July 1914, less than a year after it was designed. After some minor changes the gun was re-proofed in May 1916 with production approved in January 1917, for Gun Nos. 2–41. Bethlehem Steel was given a contract for 20 guns and an additional 20 castings were ordered from Watervlie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
41 Cm/45 3rd Year Type Naval Gun
The 41 cm/45 3rd Year Type naval gun was a breech-loading naval gun designed during World War I for the Imperial Japanese Navy. It served as the primary armament in the dreadnoughts completed after the end of the war and in coast defense mountings. Two turrets and their guns were salvaged during the 1970s from the wreck of the and are on display in Japan. Description The gun was of wire-wound construction and had an overall length of with a bore long. It weighed , including the Welin-type breech. This used the Elswick three-motion short-arm mechanism, much like the British BL 18 inch Mk I naval gun designed around the same time. Chamber volume was .Campbell, p. 181 Initially the gun was fitted in twin-gun turrets that had an elevation range of –2°/+35°. It was initially equipped with the Type 88 armor-piercing, capped (APC) shell, that had a muzzle velocity of .Campbell, p. 182 This was superseded in 1931 by the Type 91 shell that weighed .

London Naval Treaty
The London Naval Treaty, officially the Treaty for the Limitation and Reduction of Naval Armament, was an agreement between the United Kingdom, Japan, France, Italy, and the United States that was signed on 22 April 1930. Seeking to address issues not covered in the 1922 Washington Naval Treaty, which had created tonnage limits for each nation's surface warships, the new agreement regulated submarine warfare, further controlled cruisers and destroyers, and limited naval shipbuilding. Ratifications were exchanged in London on 27 October 1930, and the treaty went into effect on the same day, but it was largely ineffective. The treaty was registered in '' League of Nations Treaty Series'' on 6 February 1931. Conference The signing of the treaty remains inextricably intertwined with the ongoing negotiations, which began before the official start of the London Naval Conference of 1930, evolved throughout the progress of the official conference schedule, and continued for years ...

Lion-class Battleship
The ''Lion'' class was a class of six fast battleships designed for the Royal Navy (RN) in the late 1930s. They were a larger, improved version of the preceding ''King George V'' class, with guns. Only two ships were laid down before the Second World War began in September 1939 and a third was ordered during the war, but their construction was suspended shortly afterwards. The design was modified in light of war experience in 1942, but the two ships already begun were scrapped later in the year. None of the other ships planned were laid down, although there was a proposal in 1941 to modify one of the suspended ships into a hybrid battleship-aircraft carrier with two 16-inch gun turrets and a flight deck. Preliminary work for a new design began in 1944 and continued for the next year or so until the RN realised that they were unaffordable in the post-war financial environment. Design and description The design of the ''Lion''-class battleships was influenced by the terms of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BL 15-inch Mk I Naval Gun
The BL 15-inch Mark I succeeded the BL 13.5-inch Mk V naval gun. It was the first British 15-inch (381 mm) gun design and the most widely used and longest lasting of any British designs, and arguably the most successful heavy gun ever developed by the Royal Navy. It was deployed on capital ships from 1915 until 1959 and was a key Royal Navy gun in both World Wars. Design Gun This gun was an enlarged version of the successful BL 13.5-inch Mk V naval gun. It was specifically intended to arm the new s as part of the British response to the new generation of Dreadnought battleships Germany was building, during the naval arms race leading up to World War I. Due to the urgency of the times, the normally slow and cautious prototype and testing stages of a new gun's development were bypassed, and it was ordered straight from the drawing board. Despite its hurried development process, the gun met all expectations and was a competitive battleship main armament throughout both World ...
