USS Missouri (BB-63) ... Below it is a strake of Class B homogeneous armor plate that tapers in thickness from 12.1 inches at the top to 1.62 in (41 mm) at the bottom ...
Total armor thickness on the centerline would therefore have been 9.925 in (252 mm) over the citadel and 10.3 in (262 mm) thick over the magazines. The outboard section would have had 6.1 in (155 mm) Class B laminated on 1.25 in (32 mm) STS for a total of 7.35 in (187 mm) second deck and a 0.75 in (19 mm) splinter deck.
The citadel consisting of the magazines and engine rooms was protected by an STS outer hull plating 1.5 inches (38 mm) thick and a Class A armor belt 12.1 inches (307 mm) thick mounted on 0.875-inch (22.2 mm) STS backing plate; the armor belt is sloped at 19 degrees, equivalent to 17.3 in (439 mm) of vertical class B armor at 19,000 yards.
The primary armament of an Iowa -class battleship consisted of nine breech-loading 16 inch (406 mm)/50-caliber Mark 7 naval guns, [1] which were housed in three 3- gun turrets: two forward and one aft in a configuration known as "2-A-1". The guns were 66 feet (20 m) long - 50 times their 16-inch (406mm) bore, or 50 calibers, from breechface to ...
Missouri (BB-63), famous for being the ship on which the Japanese instrument of surrender was signed, was the last battleship in the world to be decommissioned on 31 March 1992. Seven of these ten ships are still in existence. South Dakota,Washington and Indiana were scrapped, but the remainder are now museum ships.
Main deck armor thickness ranged from 4 to 6 inches (10 to 15 cm) or even 9 inches (23 cm) for Yamato class, usually increased over magazines: lighter decks were 1.5 to 2.0 inches (3.8 to 5.1 cm) thick. [29] From the lessons of Jutland, the protection scheme incorporated a sophisticated torpedo defense system (TDS). [30]
All or nothing is a method of naval warship armor, best known for its employment on dreadnought battleships. The concept involves heavily armoring the areas most important to a ship while the rest of the ship receives no armor. [1] The "all or nothing" concept avoided light or moderate thicknesses of armor: armor was used in the greatest ...
Fast battleship. HMS Queen Elizabeth, the first "fast battleship" of the Dreadnought era, in 1918. French battleship Dunkerque. A fast battleship was a battleship which in concept emphasised speed without undue compromise of either armor or armament. Most of the early World War I -era dreadnought battleships were typically built with low design ...
