The 3"/50 caliber gun (spoken "three-inch-fifty-caliber") in United States naval gun terminology indicates the gun fired a projectile 3 inches (7.62 cm) in diameter, and the barrel was 50 calibers long (barrel length is 3" x 50 = 150" or 3.81 meters). Different guns (identified by Mark numbers) of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1890 through the 1990s on a variety of combatant and transport ship classes.

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)
