The scenario imagines six ships entering service in 1909 and another six in 1910. With further batches, Britain could have 24 to 30 or more by the First World War. In this comparison, the proposed ten-gun battery uses the largest calibre credited with retaining a heavy cruiser's rate of fire, together with useful range and accuracy. Britain already understood the 9.2-inch gun and had resources to supply it. Surplus guns could also go to shore batteries, giving the same ordnance another use.
