What if Canada bought four oil-fired Tiger-class battlecruisers?
Short answerThe Battlecruiser Fleet would gain major depth, and an early Canadian Tiger at Coronel could change the battle and remove the need for the historical Falklands response.
NotesA five-ship Tiger construction program, four for Canada plus the British ship, would give the wartime fleet a much deeper fast-capital-ship force. The timing could make one available around the Battle of Coronel. Its presence might reverse the local balance so decisively that the later Falklands response would no longer be required in its historical form.
