Ship project history: First USN battleships with Krupp-hardened armour, allowed considerably to decrease a thickness of armoured belt without protection easing. On the project the big effect was rendered by the British battleships, that was showed in atypical for the American ships armament structure, armouring scheme and high speed. New main and secondary guns with increased firing rate and shell initial velocity are mounted.
Ship protection: Main belt had 2.29m height (0.99m over and 1.30m under waterline). It connected with main gun barbettes by 229mm angled bulkheads. It was 279mm thick at upper part 1.30m in height, tapering to 191mm at lower edge between centerlines of barbettes. There was 140mm upper belt. 64mm armoured deck over citadel was flat and connected with upper edge of main belt. It had 70mm slopes at ship ends and was 64mm thick fore and 102mm aft. Turrets had 89mm crowns.
Modernizations: 1909 - 1911, all: cage masts were installed.
1909 - 1911, Maine: Niclausse boilers were replaced by 12 Babcock & Wilcox.
1919, all: - 8 x1 - 152/50 (may be temporarily); + 2 x 1 - 76/50 Mk 10 AA
