The board rejected this more expensive design and held to most of its requirements; Daniels approved these changes on 29 January 1918. Taylor investigated sloping the armor, which promised to save a lot of weight, but ultimately decided not to do so. On 6 July, the board changed its draft specification to 33 feet (10.1 m) at normal load, which meant that the ships would have to off-load weight to pass through the canal and dropped its requirement for a

The General Board's requirements were not thoroughly spelled out at the beginning of the design process and it requested a main armament of a dozen 16-inch (406 mm) guns and higher speed than the existing 21 knots of the earlier ships to counter trends it saw in fast foreign battleships like the
