Mark 16/1 Triple 6 in /47 Turret - Design

Design

A 6-inch triple turret weighed in at about 70 tons, and each rifle barrel was 23 feet 6 inches (7.16 m) long. The turret rested on a barbette or circular shaft that extended several decks into the ship. Projectiles were stored in a projectile handling room in the lower part of the barbette. Over 900 projectiles could be stored in the projectile handling room. The guns were supplied with projectiles via hoists.

Powder stores were below the projectile handling room and powder hoists fed the guns. Empty powder canisters were ejected from the turret via an ejector port at the back of the turret. When the guns were firing, it was not unusual to see empty brass canisters piling up on the deck behind the turret. The turret itself had 6.5 inches (170 mm) of armor plate on its face and could train (turn) to follow its target at ten degrees a second.

Each turret required a crew of 3 officers and 52 enlisted men.

Famous quotes containing the word design:

    Westerners inherit
    A design for living
    Deeper into matter—
    Not without due patter
    Of a great misgiving.
    Robert Frost (1874–1963)

    Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.
    Henry David Thoreau (1817–1862)

    The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.
    Karl Lagerfeld (b. 1938)
