How plausible is an alternate history in which Canada buys HMS Eagle and later operates nuclear-powered aircraft carriers?
Short answerIt would require a major change in Canadian governmental thinking and naval ambition before the country could sustain such a carrier.
NotesThe proposed sequence begins with Canada buying the retired British carrier HMS Eagle and eventually operating nuclear-powered carriers. This was a major procurement variation. It would require a significant change in how Canadian governments thought about the navy both before and after the Second World War. Political ambition and force-structure commitment are the decisive constraints in this counterfactual.
