Colorado and Nelson 16-inch guns compared

How did the Colorado-class 16-inch gun compare with the 16-inch guns on Nelson and Rodney?

Their ballistic performance was close, while the British system offered greater elevation and a somewhat higher stated firing rate.

Both the Colorado and Nelson classes carried 16-inch/45-calibre guns, following a correction of the initial 50-calibre comparison. The figures quoted give the British mounting greater elevation and about two rounds per minute, against roughly one and a half for the American weapon. Muzzle velocities are close, while the British mounting's greater elevation allows a longer stated maximum range. These figures come from a single comparison source chosen to keep the measurements consistent. The weapons also belong to different design generations: the American family originated earlier, while Nelson's gun was designed in 1922. That difference limits how much the comparison can establish about national design preferences.
