ORIGINAL: ItBurns Okay, I'll try again: How many functioning 16" caliber guns did the Battleship South Dakota have on the night of 14-15 November 1943 at the Second Naval Battle of Guadalcanal? The answer is NONE the South Dakota did not have 16” caliber guns. She had nine 16-inch guns of 45 calibers. The length of artillery barrels has often been described in terms of multiples of the bore diameter. Therefore a 16-inch gun of 45 calibers would have a barrel 45 x 16 inches = 720 inches or 60 feet long. 45 times their 16-inch (406 mm) bore, or 45 calibers from breechface to muzzle. South Dakota Class Battleship: Displacement 35,000 Tons Dimensions: 680' 4" (over all) x 108' 2" x 36' 2" (Max) Armament: 9 x 16"/45 caliber Mark 6 guns (3 turrets with 3 guns in each turret) 16 x 5"/38AA (South Dakota had 10x 5"/38AA she was set up as a flagship) 12 x 1.1" 12 x 0.5" 3 Aircraft Armor: 12 1/4" Belt, 18" Turrets, 1 1/2" +6" +1/3" Decks, 15" Conning Tower Machinery: 130,000 SHP; G.E.
