About Armament of the Iowa-class battleship in brief
The first Iowa-class ship was laid down in June 1940. The primary armament consisted of nine breech-loading 16 inch 50-caliber Mark 7 naval guns. Each gun rested within an armored turret, but only the top of the turret protruded above the main deck. The turrets were not actually attached to the ship, but sat on rollers, which meant that if the ship were to capsize the turrets would fall out. Each battleship also received four Harpoon missile magazines, Phalanx anti-aircraftanti-missile systems, and electronic warfare suites. When reactivated and modernized in the 1980s each battleship retained the original battery of nine 16-inch guns, but the secondary battery on each battleships was reduced from ten twin-gun mounts and twenty guns to six twin- gun mounts with 12 guns to allow for the installation of two platforms for the Tomahawk missiles. To distinguish between the rounds fired from different battleships the Iowa class used dye bags which allowed artillery observers to determine which rounds had been fired by which ship. Iowa, New Jersey, Missouri, and Wisconsin were assigned the colors orange, blue, red and green, respectively. After World War II the Navy switched to smoke-burning propellant, which increased the barrel life from 290 to about 350.
These measures were further augmented by the addition of polyurethane jackets, which were placed over the powder bags to reduce the gaseous erosion during firing during the Vietnam War. All four Iowas were later used on all later tours in Vietnam, and later used for later tour in Vietnam and later in the Korean War. The Iowa class was the most heavily armed gunships the U.S. Navy has ever put to sea due to the continual development of their onboard weaponry. The guns were 66 feet long bore, or 50 calibers, from breechface to muzzle). Each gun weighed about 239,000 pounds without the breech, or 267,900 pounds with the breeCh. They fired 2,700 pounds armor-piercing projectiles at a muzzle velocity of 2,500 fts, or 1, 900 pounds high-capacity projectiles at 2,690 ft, up to 24 miles. The ship could fire any combination of its guns, including a broadside of all nine. The turret could be elevated from −5° to +45°, moving at up to 12° per second, and could be rotated about 300° at a rate of about four degrees per second and can even be fired back beyond the beam, which is sometimes called \”over the shoulder.’’ “The guns were never fired horizontally forward.”“” ”” “ ” “ ”, ‚” and “ “# #”#’#‚#“#,” #’$1.4 million”.
