Britain brought an automatic 6-inch gun into operation before an 8-inch equivalent, while the American sequence ran the other way around. The explanation rests on the projects' different starting points and the direction in which each design was being scaled. The British 6-inch installation in the Tigers still involved compromises attributed here to attempts to save money. British automatic 8-inch work reached testing without becoming operational, and development associated with 8-inch and 9.2-inch cruiser guns continued for some time after the Second World War.

Why British and American automatic cruiser guns developed differently
Different development paths explain why Britain first fielded an automatic 6-inch cruiser gun while the United States succeeded first with an 8-inch weapon.
