Following the introduction of ironclad warships in the early 1860s, naval designers grappled with the problem of mounting heavy guns in the most efficient way possible, beginning with broadside box batteries and quickly moving to rotating gun turrets, since these afforded the ability to fire directly ahead, which was deemed important due to the ...
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree ...
Turrets offered the maximum arc of fire for the guns, but there were significant problems with their use in the 1860s. The fire arc of a turret would be considerably limited by masts and rigging, so they were unsuited to use on the earlier ocean-going ironclads.
Unlike a monitor-type ironclad which carried its armament encased in a separate armored gun deck/turret, it exhibited a single (often sloped) casemate structure, or armored citadel, on the main deck housing the entire gun battery. As the guns were carried on the top of the ship yet still fired through fixed gunports, the casemate ironclad is ...
The area around the gun ports was reinforced by 4.5-inch plates to give a total thickness of 10 inches. The turret roof consisted of T-shaped beams covered by 1-inch (25 mm) iron plates. Holes in the roof were provided for ventilation and for the gun captain to use to aim the turret. [10]
The four 81-ton muzzle-loading rifles were mounted in two 33-foot-10-inch-diameter (10.31 m) turrets mounted en echelon, with the forward turret mounted on the port side of the ship and the after turret on the starboard side. The superstructure both fore and aft was very narrow to allow one gun in each turret to fire axially, i.e. directly ...
Tonnant was a coastal defense ship built for the French Navy (Marine Nationale) that served during the last two decades of the nineteenth century.Initially envisaged to mount two 340 mm (13.4 in) guns in a single turret, the design was redone with the guns mounted in two barbette turrets.
Gun turret: 4.5 in (110 mm) Rolf Krake was a Danish turret ironclad built in Scotland during the 1860s. The vessel was designed by Cowper Phipps Coles , a pioneering naval architect, and was the first warship of any navy to carry a turret of the type designed by Coles.
