Design [] Armor []. A view of the door and 17-inch (430 mm) thick armored citadel of the battleship New Jersey. Like all battleships, the Iowas carried heavy armor protection against shellfire and bombs with significant underwater protection against torpedoes.The Iowas ' armor scheme was modeled on that of the preceding South Dakota class, and designed to give a …
The upper belt is Class A armor, 12.1 inches thick, while the lower belt is Class B armor, 12.1 inches thick at the top and tapered to 1.62 inches at the bottom. The deck consists of three parts, the bomb deck, the main armor deck, and the splinter deck. The bomb deck is 1.5 inches STS plate, the main armor deck is 4.75 inches Class B armor laid on
The Iowa Class was designed at a time when the US navy embraced the "all-or-nothing" scheme of armor protection. Heavy armor was restricted to the vital parts of the Iowa Class, and made thick enough to prevent large caliber shells from penetrating it.
Iowa class belt armor thickness. Many sources seem to list the Iowa class as having 12.1" (307mm) of Class A armor while others list it as having 12.2" (310mm) which is the same as on the preceding South Dakota class. Both are backed by 0.875" (22mm) of STS. As the armor scheme on the Iowas were carried over from the South Dakotas with only ...
The Iowa ' s "all-or-nothing" armor scheme was largely modeled on that of the preceding South Dakota class, and designed to give a zone of immunity against fire from 16-inch/45-caliber guns between 18,000 and 30,000 yards (16,000 and 27,000 m; 10 and 17 mi) away.
Even as more advanced battleships such as the Iowa (32 knots) and Bismarck classes (30 knots) came into service, the Richelieu class remained competitive in speed. The Richelieu class were true fast battleships, designed with just as much emphasis on speed as she had on armor and firepower.
The Iowa Class was designed at a time when the US navy embraced the "all-or-nothing" scheme of armor protection. Heavy armor was restricted to the vital parts of the Iowa Class, and made thick enough to prevent large caliber shells from penetrating it. All other parts of the ships were left unarmored in any meaningful way.
The Yamato class boasted 410mm belt armor and 650mm turret armor while the Iowa class had 307mm belt armor and 500mm turret armor. Additionally, the Yamato was a good deal slower than the Iowa class clocking in at a sluggish 27 knots compared to Iowa's 33 knots.
The Iowa-class battleships had the characteristic "all-or-nothing" armor scheme seen in preceding American battleships, with the thickest armor around the citadel between Turrets A and Turret C. The outer hull plate was 38mm Special Treatment Steel (STS) and the side armor of 307mm was angled at 19-degrees inwards in order to confer greater ...
Armor Schemes on W.W.II Battleships. USS Wisconsin. Photo by Ingalls Shipbuilding. IOWA class battleship turrets varied in face thickness slightly, due to the manufacturer's limitations. As an example, the SOUTH DAKOTA Class battleship ALABAMA had solid 19" Class "B" armor turret faces, while the others had 18-19.5" (roughly) turret faces, in ...
The Iowas' internal armor protection scheme was similar in arrangement to that of the South Dakota class, and was designed to keep out the armor-piercing shells originally intended for their guns, though not the heavier (2700 pound) shells ultimately used.
The second basic factor, after firepower, to be considered was Iowa class armor. The armor scheme was a copy of the armor used on North Carolina …
The Iowa Class Battleships. This idea was the founding principle behind the Iowa class. A series of design schemes were introduced before eventually evolving into two competing designs. The first design was drawn up by members of the Naval Board that still believed in the armor and firepower elements. This was a larger South Dakota class vessel ...
Much of the Iowa class BB armor scheme was based on the preceding South Dakota class armor scheme. The only example the SoDak armor was 'tested' in battle with BB caliber shells was USS South Dakota (BB57) getting shells by one 14" HC, and possibly one 14" AP shell hit on Turret #3 barbette by Kirishima at GC2.

Answer (1 of 7): It depends. With all or nothing you have superbly protected 'vitals' (barbettes,turrets etc) and the rest of the ship is basically unarmoured. Bismarck used a modernised version of incremental armour scheme (NOT some WW1 armour like you'll commonly hear online) that allowed gap...
