Obviously true
Stats for the "Yorkshire" class, from the S&P article that covers RN ships that didn't make it into OOB.....
Yorkshire class Cruiser
A larger heavy cruiser was on the design tables at the same time as the “Surrey” class. The bigger ship, referred to only as the “X” design shared many features of the Surrey but had a fifth 8” turret, giving it a broadside of ten guns. Like the Surrey the Yorkshire class were cancelled, but unlike the Surreys names were never allocated. The names below are conjectural, but follow the convention of naming heavy cruisers after British counties.
