The turrets weighed 1,048 tonnes (1,031 long tons; 1,155 short tons) to 1,056 tonnes (1,039 long tons; 1,164 short tons), [4] rested on ball bearings on a 8.75 metres (28.7 ft) diameter track, could elevate 6° per second and traverse 5.4° per second. The guns were loaded at +2.5° and used a telescoping chain-operated rammer.
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 467.11 litres (28,505 cu in). [1] Rear view of the gun on display at the Yamato Museum. Initially the gun was fitted in twin-gun turrets that had an elevation range of –2°/+35°. [2]
Owing to the interchangeability of the guns, the battleships fitted with the 14-inch/45-caliber guns often had guns of various Marks installed on each turret. [ 3 ] In the 1930s, the Mark 1, 2, 3, and 5 were upgraded to allow for increased charges and muzzle velocities, resulting in the Mark 8, 9, 10, and 12, respectively.
The turret interiors were subdivided and designed to permit the independent loading, elevation and firing of each gun. Each turret was fitted with an optical range finder, ballistic analog computer, and a switchboard. The rangefinder and ballistic computer permitted the turret's gun captain and crew to locally engage targets should battle ...
The built-up guns were used on the two battleships of the Richelieu class, Richelieu and Jean Bart.They were mounted in quadruple turrets, which allowed mounting all the main battery at the bow, and saved weight on turret armour in the context of the Washington Naval Treaty.
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 ...
The turret is capable of unlimited full circle traverse at up to 70° per second and elevates from 10° below to 85° above horizontal at up to 40° per second. [1] The turret's on-board computers do the ballistic calculations and fire-control. The high level of self-containment and compact size and low weight allows installation on a wide ...
