Ship project history: Large armoured cruisers intended for operations as fast squadron of battle fleet (similar as Kamimura`s cruisers in the Russian-Japanese war). They (in particular, by armour arranging) remind the predecessors by main concepts, but the project was notably improved, in particular main guns were more powerful.
Ship protection: Main belt thickness was 127mm. Armoured deck over citadel was 38mm behind the belt at flat part and connected with lower belt edge by 102mm slopes. This deck was 76mm with 102mm slopes at ship ends. Barbette bases connected with armour deck and were 102mm at lower edge. Upper part of barbettes was 178 or 203mm thick. Turrets had 229mm faces, 178mm sides, 127mm rears and 64mm crowns. Secondary guns were protected by 127mm casemates.
Modernizations: 1911, all: new cage foremasts were installed
1914 - 1919, all surived: - 12 x 1 - 152/50 (may be temporarily), 10 x 1 - 76/50; + 2 x 1 - 76/50 Mk 10 AA
1915, North Carolina (temporarily), 1917, Seattle (temporarily): + 1 catapult, 4 airplanes
Naval service: In 1916-1920 they were renamed to "exempt" names for built battleships. Seattle in 1923-1927 served as a flag depot ship of USN. Memphis was a victim of 30m high tsunami at Haiti. She was driven ashore by the wave, a total wreck. Seattle was listed as "unclassified" from 1931, re-classified as IX39 in February, 1941 and stricken in 1946.
