The 3"/23 caliber gun (spoken "three-inch-twenty-three-caliber") was the standard anti-aircraft gun for United States destroyers through World War I and the 1920s. United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 23 calibers long (barrel length is 3" x 23 = 69" or 1.75 meters.)

Famous quotes containing the word gun:
“What cannot stand must fall; and the measure of our sincerity and therefore of the respect of men, is the amount of health and wealth we will hazard in the defence of our right. An old farmer, my neighbor across the fence, when I ask him if he is not going to town-meeting, says: “No, ‘t is no use balloting, for it will not stay; but what you do with the gun will stay so.””
—Ralph Waldo Emerson (1803–1882)
