The proposed 15-inch/50 belonged to Britain's early-1920s F2 and F3 design work, well before the later choice between 14-inch and 16-inch weapons. The longer 15-inch gun promised substantial striking power without abandoning a caliber already familiar across the fleet. It should not be confused with the 15-inch/45 Mark II considered against a 14-inch weapon in the 1930s. Illustrations of Hood and Warspite with triple mounts show how radical the resulting ships might have looked, while remaining speculative rather than completed designs.

A proposed British 15-inch/50 gun opens an alternate path from the F2 and F3 studies to faster capital ships with heavy triple turrets.
