Did the choice between 6-inch/50 and 8-inch/50 cruiser guns involve more than rate of fire and shell weight?
Short answerThose differences are treated as sufficient: the 6-inch gun fired faster, while the 8-inch gun delivered a heavier shell.
NotesThe 6-inch/50 gun's faster rate of fire and the 8-inch/50 gun's heavier shell are treated as sufficient reasons for the choice between them. No additional design factor is proposed.
