Would British treaty cruisers use triple 6-inch turrets if earlier light cruisers already used twins?
Short answerVery likely, because triples add firepower efficiently within treaty tonnage limits.
NotesEarlier light cruisers with twin 6-inch mountings would make a later move to triples highly likely. Triple turrets would add firepower efficiently within the weight and tonnage available. That advantage would be particularly attractive under treaty limits.
