5"/25 Caliber Gun (United States)
The 5"/25 caliber gun (spoken "five-inch-twenty-five-caliber") was the standard anti-aircraft gun for United States Washington Naval Treaty cruisers. The gun was also mounted on pre-World War II battleships and aircraft carriers until replaced by the standard dual-purpose 5"/38 caliber gun. United States naval gun terminology indicates the gun fired a projectile 5 inches (127 mm) in diameter, and the barrel was 25 calibers long (that is, for a 5" bore and a barrel length of 25 calibers, 5" x 25 = 125", or about 3.2 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)
