What Royal Navy ship with many 14-inch guns was previously discussed?
Short answerIt was an alternate Dreadnought concept with five triple 14-inch turrets, whose adoption could have transformed the early dreadnought race.
NotesA reported Vickers-Elswick triple turret for 14-inch guns opens an alternative to Dreadnought's twin 12-inch mountings, although its precise stage of development remains uncertain. The missed-train story that might have brought the project to Fisher's attention is probably apocryphal. Five triple turrets would give the hypothetical ship fifteen heavy guns, with a larger hull potentially accommodating enough machinery for 22-24 knots. The proposed mounting allowed about 25 degrees of elevation, probably with the guns moving together in a common cradle. A British ship combining that speed and armament would make Germany's readily available 11-inch guns a much harder choice to defend and put pressure on other navies to adopt heavier weapons sooner.
