ST. American cruisers.
Columbia (Cleveland), tier VIII.
Base firing range of the main battery is increased from 13.3 to 14.2 km and its reload time is decreased from 7 to 6.5 seconds.
Buffalo, tier IX.
Base surface detectability is increased from 13.14 to 13.62 km. Penalty after firing from a smokescreen with main battery is increased from 7.6 to 7.98 km.
Pittsburgh (Baltimore), tier VIII.
Hull plating thickness is increased from 25 to 27 mm. This will help the ship withstand most of the 155-mm HE shells and cause 380 mm AP shells to ricochet when the cruiser is angled correctly. Main battery reload time is decreased from 13 to 10 seconds.
Salt Lake City (Pensacola), tier VI.
Guns are replaced - 203mm/55 Mk14 instead of 203mm/50 Mk14. The guns are now historically correct.
Shell stats for the new weaponry.
HE: muzzle velocity - 823 m/s (up from 792 m/s). AP: muzzle velocity - 853 m/s (up from 792 m/s), maximum damage - 4600 (up from 4500). Other stats remain unchanged.
The American cruisers received a range of improvements as a result of testing and are now much better balanced against other ships of the class.
