What would a completely Vickers-designed and built battleship or battlecruiser for a 1913 customer look like?
Short answerIt would be a heavily armed 14-inch triple-turret design built around Vickers guns, armor, and fire control, with speed depending on bought-in machinery and budget.
NotesA likely Vickers proposal would use 14-inch guns in triple turrets, potentially as many as fifteen barrels. The company would favour selling its guns, armour and fire-control equipment, while obtaining boilers and turbines elsewhere. That emphasis would not necessarily produce the fastest ship. A customer prepared to pay more could obtain a stronger machinery fit, with Parsons turbines explicitly mentioned.
