Talk:12.7cm Twin Gun Mount Model B Kai 2/@comment-73.239.102.38-20161225160510/@comment-26334968-20170429082800

There were not a single country in the world who built or even designed a destroyer with triple or even qith quad main guns. the medium and small calibre AA guns (57mm and smaller) are a different type of guns so I did not count them.

Though the USN designed a triple turret for the 5"/38 Mark 12 gun to be used on battleships (North Carolina preliminaries) but not for destroyer or even cruiser use and the British used the 4"/45 Mark IX gun in triple mount on battlecruisers.
