Vickers 14 inch/45 naval gun

The Vickers 14 inch 45 calibre gun was designed and built by Vickers and initially installed on the battlecruiser Kongō which it was building for the Imperial Japanese Navy. Guns to this Vickers design were also later built in Japan to arm Kongō's sister ships and subsequent Japanese-constructed "super-dreadnoughts" which were all built in Japan.
