What British or American turret could most easily rearm a captured Jean Bart?
Short answerA British quad 14-inch installation is the most immediately practical, while triple 16-inch guns are a possible but less readily available alternative.
NotesBritain could consider several replacements for Jean Bart's existing turrets after bringing the incomplete ship to an Allied yard. Triple 16-inch turrets might fit geometrically, but quad 14-inch equipment and production experience were closer to hand. That availability makes a British quadruple mount the easier near-term option even if a larger gun is more attractive on paper. Reallocating King George V-class turrets would create further problems, including the arrangement of gun groups and their aiming points. Supply, completed machinery, and integration effort govern conversion choices as much as caliber.
