Eight Babcock and Wilcox boilers supplied four geared turbines and four shafts for a projected 28-knot maximum speed. The main battery comprised twelve 16-inch/50-calibre Mark 7 guns in four triple turrets. A range of 15,000 nautical miles at 15 knots suited a fleet expected to cross the Pacific. Normal complement exceeded 2,300, and flagship service could raise it to 2,789. The extra staff of more than 400 points to fleet command rather than a local squadron role.
