Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the ...
Background. HMS Prince Albert, a pioneering turret ship, built by naval engineer Cowper Phipps Coles. Before the development of large-calibre, long-range guns in the mid-19th century, the classic ship of the line design used rows of port-mounted guns on each side of the ship, often mounted in casemates. Firepower was provided by a large number ...
In the 1870s, designers began to experiment with an en barbette type of mounting. The barbette was a fixed armoured enclosure protecting the gun. The barbette could take the form of a circular or elongated ring of armour around the rotating gun mount over which the guns (possibly fitted with a gun shield) fired.
Although the main armament of ships quickly began to be mounted in revolving gun turrets, secondary batteries continued to be mounted in casemates; however, several disadvantages eventually also led to their replacement by turrets. In tanks that do not have a turret for the main gun, the structure that accommodates the gun is also called a ...
Gun laying. Gun laying is the process of aiming an artillery piece or turret, such as a gun, howitzer, or mortar, on land, at sea, or in air, against surface or aerial targets. It may be laying for either direct fire, where the gun is aimed directly at a target within the line-of-sight of the user, or by indirect fire, where the gun is not ...
Captain Cowper Phipps Coles, C.B., R.N. (1819 – 7 September 1870), was an English naval captain with the Royal Navy. Coles was also an inventor; in 1859, he was the first to patent a design for a revolving gun turret. Upon appealing for public support, his turrets were installed on HMS Prince Albert and HMS Royal Sovereign.
The gun itself is fixed to the upper part of the turret. Elevation of the gun is achieved by tilting the entire upper part of the turret. In conventional designs, the gun is mounted inside the one-piece turret by a trunnion, and its elevation is changed by tilting on that trunnion while the turret remains in fixed position relative to the hull ...
The primary armament of an Iowa -class battleship consisted of nine breech-loading 16 inch (406 mm)/50-caliber Mark 7 naval guns, [1] which were housed in three 3- gun turrets: two forward and one aft in a configuration known as "2-A-1". The guns were 66 feet (20 m) long - 50 times their 16-inch (406mm) bore, or 50 calibers, from breechface to ...
