The deck armor consists of a 1.5-inch-thick (38 mm) STS weather deck, a combined 6-inch-thick (152 mm) Class B and STS main armor deck, and a 0.63-inch-thick (16 mm) STS splinter deck. Over the magazines, the splinter deck is replaced by a 1-inch (25 mm) STS third deck that separates the magazine from the main armored deck. [72]
Plastic armour replaced the use of concrete slabs which, although expected to provide protection, were prone to cracking and breaking up when struck by armour-piercing bullets. Plastic armour was effective because the very hard particles would deflect bullets which would then lodge between the plastic armour and the steel backing plate.
Tennessee, California and West Virginia were even more thoroughly rebuilt, incorporating not just changes similar to Nevada but increased deck armour, torpedo bulges and improved subdivision and a modern radar and electronics suite, though their widened beam exceeded the Panama Canal restrictions which limited their operations to the Pacific.
Below this deck, the roof of the armored citadel is formed by 6 in (152 mm) of armor in two layers. Below this is a deck of 0.625-inch (16 mm) STS plates intended to stop splinters from shells that pierced the armored deck above it. The armor deck extends aft and the roof of the steering gear compartment is 6.2 in (160 mm) thick. [14]
The armor deck was connected to the top of the belt. One deck below, another layer of armor 1.5 in (38 mm) thick was intended to contain splinters from shells and bombs that were detonated by the upper deck. The sides of the deck sloped down and were increased slightly to 2 in (51 mm) thick, and they were connected to the bottom edge of the belt.
While flight-deck-level armour was eventually adopted by the Americans for the Midway design, the strength deck remained on the hangar level. Midway had originally been planned to have a very heavy gun armament (8-inch weapons). The removal of these weapons freed up enough tonnage to add 3 inches (76 mm) of armour at the flight deck level.
The armor of the barbettes was 18 to 4.5 inches (457 to 114 mm) thick. The conning tower was protected by 16 inches (406 mm) of armor and had a roof eight inches thick. [3] The main armor deck was three plates thick with a total thickness of 3 inches; over the steering gear the armor increased to 6.25 inches (159 mm) in two plates.
HMS Dreadnought was a Royal Navy battleship, the design of which revolutionised naval power.The ship's entry into service in 1906 represented such an advance in naval technology that her name came to be associated with an entire generation of battleships, the dreadnoughts, as well as the class of ships named after her.
