5"/54 Caliber Mark 45 Gun - History

History

Development started in the 1960s as a replacement for the 5"/54 caliber Mark 42 gun system with a new, lighter, and easier to maintain gun mounting. In USN use, the Mark 45 is used with either the Mk 86 Gun Fire Control System or the Mk 160 Gun Computing System. Since before World War II, 5" has been the standard gun caliber for U.S. Naval ships. Its rate of fire is lower than the British 4.5-inch (114 mm) gun, but it fires a heavier 5" shell which carries a larger burst charge that increases its per-shell effectiveness against aircraft.

Famous quotes containing the word history:

    “Psychology keeps trying to vindicate human nature. History keeps undermining the effort.”
    —Mason Cooley (b. 1927)

    “The view of Jerusalem is the history of the world; it is more, it is the history of earth and of heaven.”
    —Benjamin Disraeli (1804–1881)

    “The myth of independence from the mother is abandoned in mid- life as women learn new routes around the mother—both the mother without and the mother within. A mid-life daughter may reengage with a mother or put new controls on care and set limits to love. But whatever she does, her child’s history is never finished.”
    —Terri Apter (20th century)
