Weight of broadside: 12031 lbs
Main belt, 13.0 inches; ends unarmored
Armor deck, average 4.0 inches
C.T., 4.0 inches
Battery armor:
Main, 15.0" / secondary, 3.0"
AA, 1.0" shields / light guns, 1.0" shields
Maximum speed for 70024 shp = 26.38 knots

Remarks:
Relative extent of belt armor, 81 percent of 'typical' coverage.
Magazines and engineering spaces are roomy, with superior
watertight subdivision.
Ship is roomy, with superior accommodation and working space.
