The Royal Navy had quite a few different calibers of guns in the interwar and World War II period, which is rather strange considering there weren't many ships being built. Also, unlike the IJN or USN, which would most likely be able to operate out of their home country, or at least nearby ports, the Royal Navy had to be capable of operations across a vast Empire. Given that it wasn't building many ships and had a more complicated logistical situation than any other fleet, why did the Royal Navy essentially operate custom armaments used on only a class or two of ships?
