The mighty Iowa Class Battleships are known for their heavy armor, yet their bank vault-like conning towers were possibly the most blatant example of how over-engineered these vessels were so that they could take a brutal beating and keep on fighting.
These armored inner-bridges were massive steel cylinders that rose three stories high, from deck three to deck five. Deck three’s conning tower compartment was used by the Admiral and their staff. Deck four’s was used as the primary navigational interface for the ship. Deck five’s section of the conning tower was used by the ship’s gunnery officers.
Aside from the navigational bridge, two other control centers used for steering and navigation existed. This included one on the fly bridge and one in a control room in the lower rear of the ship, near its rudders.
The Iowa Class’s conning towers featured 17 inches of protective armor all around, with tiny slits used for outward visibility. A pair of 400 pound doors, one on each end of the bridge, allowed for access into the conning tower. From there the ship could continue to be maneuvered and officers could give orders to the ship’s 1,500 person crew even as the ship was being chewed up by enemy strafing and bombardment or set ablaze. They were among the safest places to be on these fortress-like ships during an attack.
