What if Canada fielded four Tiger-derived battlecruisers at Dogger Bank and charged the German scouting group?
Short answerThe extra Tigers would probably annihilate the German battlecruisers, while their design would reinforce the Royal Navy's shift from a dense battlecruiser toward true fast battleships.
NotesFour Canadian Tiger derivatives joining HMS Tiger would give the British enough fast heavy ships to overwhelm the First Scouting Group. The scenario also distinguishes Tiger's compact, solid battlecruiser design from Renown and Repulse and from Hood's incomplete movement toward a fast battleship. For the Royal Navy, the Queen Elizabeth approach ultimately offered a better balance than continuing Tiger's line.
