Would CVA-01 have been less likely to be cancelled if it were nuclear powered?
Short answerProbably, because a nuclear carrier would become a prestigious national industrial project whose cancellation carried a much higher political cost.
NotesThe Royal Navy avoided nuclear propulsion partly because of the large support programme it would require. That economy could be politically self-defeating: once Britain committed to a nuclear carrier, cancelling a unique national technology project while the United States led the field and France considered one would become much harder.
