Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms) , bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifling , rifled barrel, the distance is measured between opposing Rifling#C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
12 Cm 11th Year Type Naval Gun
The 12 cm 11th Year Type naval gun was a Japanese naval gun and coast defense gun used on submarines, minesweepers, and torpedo boats of the Imperial Japanese Navy during World War II. Design The 12 cm 11th Year Type was a 1922 redesign of the earlier 12 cm/45 3rd Year Type naval gun. The 11th Year Type was a typical built-up gun the period with a central rifled tube surrounded by layers of reinforcing tubes. There may have also been an autofretted mono-block barreled version of the same gun. Estimates on the length of the barrel range between 40 and 45 calibers. The 11th Year Type barrel rested in a ring cradle on a pedestal mount and had a hydro-pneumatic recoil mechanism that consisted of one recoil cylinder below the barrel and two on top. The 11th Year Type differed from the earlier 3rd Year Type because it had a horizontal sliding-block breech and fired separate loading cased charges and projectiles while the earlier gun fired separate loading bag ...

6-inch Gun M1897
The 6-inch gun M1897 (152 mm) and its variants the M1900, M1903, M1905, M1908, and M1 (a.k.a. T2) were coastal artillery pieces installed to defend major American seaports between 1897 and 1945. For most of their history they were operated by the United States Army Coast Artillery Corps. They were installed on disappearing carriages or pedestal (a.k.a. barbette) mountings, and during World War II many were remounted on shielded barbette carriages. Most of the weapons not in the Philippines were scrapped within a few years after World War II. 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. ...

BL 6 Inch Mk VII Naval Gun
The BL 6-inch gun Mark VII (and the related Mk VIII) was a British naval gun dating from 1899, which was mounted on a heavy travelling carriage in 1915 for British Army service to become one of the main heavy field guns in the First World War, and also served as one of the main coast defence guns throughout the British Empire until the 1950s. Background The gun superseded the QF six-inch gun of the 1890s, a period during which the Royal Navy had evaluated QF technology (i.e. loading propellant charges in brass cartridge cases) for all classes of guns up to to increase rates of fire. BL Mk VII returned to loading charges in silk bags after it was determined that with new single-action breech mechanisms a six-inch BL gun could be loaded, a vent tube inserted and fired as quickly as a QF six inch gun. Cordite charges in silk bags stored for a BL gun were also considered to represent a considerable saving in weight and magazine space compared to the bulky brass QF cartri ...

BL 6 Inch Gun Mk V
The BL 6 inch gun Mk V Mk V = Mark 5. Britain used Roman numerals to designate Marks (models) of ordnance until after World War II. Hence this was the fifth model of BL 6-inch gun in British service. was an early Elswick Ordnance Company breech-loading naval gun originally designed to use the old gunpowder propellants. They were used for coast defence around the British Empire. Description and service This was an Elswick Ordnance export design, completely different from and longer (30-calibres, 183.5 inch bore) than the contemporary 26-calibres British naval service 6-inch Mk III, IV and VI guns designed by the Royal Gun Factory, although it fired the same 100-pound projectiles. The gun was of a complex all-steel built-up construction, of a steel A-tube surrounded by multiple steel hoops, breech-piece and jacket. Several were acquired by the British government for coast defence in the UK and were given the designation 6-inch gun Mark V. The breech fittings and firing m ...

Canon De 145 L Modele 1916 Saint-Chamond
Canon de 145 L modèle 1916 Saint-Chamond or 145 L 16 was a French heavy artillery piece designed and produced during the First World War. From 1918, many were rebored to use 155 mm shells and renamed Canon de 155 L modèle 1916 Saint-Chamond (155 L 16). A number of 145 and 155 guns were still on hand during the Second World War and served as coastal artillery in the French, Italian and German services. History The French Army had been pursuing the replacement of the Canon de 155mm L Mle 1877 de Bange gun since 1909. Spurred by the events in the Russo-Japanese war of 1904–5 it was realised that relying on an old gun which was almost immobile for long range artillery support was not a viable strategy. The French Army Artillery Technical Committee produced requirements for a de Bange replacement in November 1909. The requirements included two different guns with a range of 13 to 14 km with a maximum elevation of 35 to 40 degrees and a modern mobile carriage. It was sug ...

It was also the most common Japanese coast-defense gun during World War II. "Third year type" refers to the Welin breech block on this gun. Breech-block design began in 1914, the third year of the ''Taishō'' period. This breech-block design was also used on Japanese 40 cm (16 inch), 20 cm (8 inch), 15.5 cm (6 inch), 12.7 cm (5 inch), and 12 cm (4.7 inch) naval guns. This gun was not mounted aboard submarines.

130 Mm/50 B13 Pattern 1936
The 130 mm/50 B13 Pattern 1936 was a 50 caliber Soviet naval gun. The gun was used as a standard destroyer weapon during World War II, and it was also used as a coastal gun and railway gun. The gun was produced in three different versions which all had incompatible ammunition and range tables. Mountings for the weapon included single open mounts and twin turrets. Besides the Soviet Union, the gun was used on ships sold or donated to Poland, People's Republic of China, Egypt and Indonesia. Finland captured five guns during Continuation War and used them until the 1990s.
