What if the High Seas Fleet had seven Bayern-class battleships?
Short answerBritain would probably order many more capital ships and might accelerate 18-inch-gun construction, while German infrastructure remained the limiting factor.
NotesProducing seven completed Bayerns would require Germany to begin with a much larger order than the four historical hulls. Britain would answer the resulting concentration of 15-inch-gun battleships with another round of numerical and technical escalation. Faster R-class successors with 18-inch guns become more plausible in that race. German yards and supporting infrastructure might still be unable to complete such an enlarged programme before the war's outcome changed.
