Gauge (bore Diameter)
The gauge (or commonly bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) of the barrel. Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the sphere's weight as a fraction of a pound, e.g., a one-twelfth pound lead ball fits a 12-gauge bore. Thus there are twelve 12-gauge balls per pound, etc. The term is related to the measurement of cannon, which were also measured by the weight of their iron round shot; an 8-pounder would fire an 8 lb (3.6 kg) ball. Gauge is commonly used today in reference to shotguns, though historically it was also used in large double rifles, which were made in sizes up to 2 bore during their heyday in the 1880s, being originally loaded with black powder cartridges. These very large rifles, called " elephant guns", were intended for use primarily in Africa and Asia for hunting ...

5-inch Gun M1897
The 5-inch gun M1897 (127 mm) and its variant the M1900 were coastal artillery pieces installed to defend major American seaports between 1897 and 1920. For most of their history they were operated by the United States Army Coast Artillery Corps. They were installed on balanced pillar (a form of disappearing carriage) or pedestal (aka barbette) mountings; generally the M1897 was on the balanced pillar mounting and the M1900 was on the pedestal mounting. All of these weapons were scrapped within a few years after World War I. History In 1885, William C. Endicott, President Grover Cleveland's Secretary of War, was tasked with creating the Board of Fortifications to review seacoast defenses. The findings of the board illustrated a grim picture of existing defenses in its 1886 report and recommended a massive $127 million construction program of breech-loading cannons, mortars, floating batteries, and submarine mines for some 29 locations on the US coastline.

5"/25 Caliber Gun
The 5"/25 caliber gun (spoken "five-inch-twenty-five-caliber") entered service as the standard heavy anti-aircraft (AA) gun for United States Washington Naval Treaty cruisers commissioned in the 1920s and 1930s. The goal of the 5"/25 design was to produce a heavy AA gun that was light enough to be rapidly trained manually. The gun was also mounted on pre-World War II battleships and aircraft carriers until replaced by the standard widespread dual-purpose 5"/38 caliber gun, which was derived from the 5"/25. Guns removed from battleships were probably converted for submarine use by late 1943, while a purpose-built variant for submarines was available in mid-1944, and was widely used by them.Campbell 1985 p.137 United States naval gun terminology indicates the gun fired a projectile 5 inches (127 mm) in diameter, and the barrel was 25 calibers long (that is, for a 5" bore and a barrel length of 25 calibers, 5" x 25 = 125", or about 3.2 meters).Fairfield 1921 p.156 It is ...

5"/50 Caliber Gun
The 5"/50 caliber gun (spoken "five-inch-fifty-caliber") was the first long barrel gun of the United States Navy and was used in the secondary batteries of the early dreadnought battleships, various protected cruisers, and scout cruisers. They were also refitted in the secondary batteries of the armored cruiser and the protected cruisers. They were later used on cargo ships, store ships and unclassified auxiliaries during World War II as well as in emergency coastal defense batteries. Design The Mark 5, Nos. 200 – 286, was a 50 caliber naval gun of a simplified construction by combining the breech piece along with the chase hoop into one long tube that was shrunk on from the muzzle. Mod 1 was a Mod 0 gun that was relined with a conical nickel-steel liner and an additional gun-steel chase hoop Hoop or Hoops may refer to: Arts and entertainment Film and television * ''Hoops'' (TV series), an American animated series Music * Hoops (band), an American indie pop ba ...

5"/51 Caliber Gun
5"/51 caliber guns (spoken "five-inch-fifty-one-caliber") initially served as the secondary battery of United States Navy battleships built from 1907 through the 1920s, also serving on other vessels. United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 51 calibers long. Description The different marks of the gun were Marks 7, 8, 9, 14, and 15. The built-up gun consisted of a tube, full-length jacket, and single hoop with side swing Welin breech block and Smith-Asbury mechanism for a total weight of about 5 metric tons. Some Marks included a tapered liner. A charge of smokeless powder gave a projectile a velocity of . Range was at the maximum elevation of 20 degrees. Useful life expectancy was 900 effective full charges (EFC) per liner.Campbell 1985 p.136 US service The 5-inch/51 caliber gun was designed to engage destroyers, torpedo boats, and other surface targets.

5"/38 Caliber Gun
The Mark 12 5"/38 caliber gun was a United States dual-purpose naval gun, but also installed in single-purpose mounts on a handful of ships. The 38 caliber barrel was a mid-length compromise between the previous United States standard 5"/51 low-angle gun and 5"/25 anti-aircraft gun. United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 38 calibers long. The increased barrel length provided greatly improved performance in both anti-aircraft and anti-surface roles compared to the 5"/25 gun. However, except for the barrel length and the use of semi-fixed ammunition, the 5"/38 gun was derived from the 5"/25 gun. Both weapons had power ramming, which enabled rapid fire at high angles against aircraft. The 5"/38 entered service on , commissioned in 1934, the first new destroyer design since the last ''Clemson'' was built in 1922. The base ring mount, which improved the effective rate of fire, entered service on , commissione ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

5"/54 Caliber Mark 42 Gun
The Mark 42 5"/54 caliber gun (127mm) is a naval gun (naval artillery) mount used by the United States Navy and other countries. It consisted of the Mark 18 gun and Mark 42 gun mount. United States naval gun terminology indicates the gun fires a projectile in diameter, and the barrel is 54 calibers long (barrel length is 5" × 54 = 270" or 6.9 meters.) In the 1950s a gun with more range and a faster rate of fire than the 5"/38 caliber gun used in World War II was needed, therefore, the gun was created concurrently with the 3"/70 Mark 26 gun for different usages. The 5"/54 Mk 42 is an automatic, dual-purpose (air / surface target) gun mount. It is usually controlled remotely from the Mk 68 Gun Fire Control System, or locally from the mount at the One Man Control (OMC) station. The self-loading gun mount weighs about including two drums under the mount holding 40 rounds of semi-fixed case type ammunition. The gun fires projectiles at a velocity of .Baile ...

5"/54 Caliber Mark 45 Gun
The 127 mm (5")/54 caliber (Mk 45) lightweight gun is a U.S. naval artillery gun mount consisting of a L54 Mark 19 gun on the Mark 45 mount. It was designed and built by United Defense, a company later acquired by BAE Systems Land & Armaments, which continued manufacture. The latest 62-calibre-long version consists of a longer-barrel L62 Mark 36 gun fitted on the same Mark 45 mount. The gun is designed for use against surface warships, anti-aircraft and shore bombardment to support amphibious operations. The gun mount features an automatic loader with a capacity of 20 rounds. These can be fired under full automatic control, taking a little over a minute to exhaust those rounds at maximum fire rate. For sustained use, the gun mount would be occupied by a six-person crew (gun captain, panel operator, and four ammunition loaders) below deck to keep the gun continuously supplied with ammunition.

Oto Melara
OTO Melara was a subsidiary of the Italian company Finmeccanica, today Leonardo, active in the defence sector, with factories in Brescia and La Spezia. The Mod 56 pack howitzer, in service throughout the world, and the 76mm naval gun, adopted by 53 navies and installed on over 1,000 naval vessels, are among OTO Melara's best known weapons since World War II. From 1 January 2016, the activities of OTO Melara merged into Leonardo's Defence Systems Division, within the Electronics, Defence and Security Systems Sector. History Pre–World War I It was founded in 1905 as a joint venture of Vickers and Terni Steelworks, Cantiere navale fratelli Orlando and Cantieri navali Odero. Investment was also provided by Giuseppe Orlando and Attilio Odero. During World War I, Vickers Terni produced many weapons with calibre 40 mm and upwards. In 1929 the company was renamed Odero Terni Orlando with the abbreviation OTO. During World War II, mostly heavy guns for battleships ...

Otobreda 127/54 Compact
The Otobreda 127mm/54 Compact (''127/54C'') gun is a dual purpose naval artillery piece built by the Italian company Oto Melara. It uses the 127mm round which is also used in the 5 inch/ 54 gun, albeit that this gun calibre is measured in United States customary units rather than metric. The gun uses an automatic loading system where 66 127mm rounds of various kinds can be stored ready-to-fire in three loader drums (each holding 22 rounds). The barrel is water-cooled. Currently the gun is still in use by navies around the world but it is slowly being replaced by the Otobreda 127/64 for new vessels, such as the German Navy's F125-class frigate and Italian Navy's FREMM. OTO Melara 127/64 A replacement of the 127/54 compact, Oto Melara started the design in 1992, and completed it in 2003. The new lightweight gun, weighing 17 tons without magazine or ammunition handling, has a rate of fire of 35 rpm, and can fire the long range guided Vulcano ammunition. Operators The Oto ...
