Yes, nuclear powered? Despite smaller size and tonnage. This carrier can only goes 27knots with a nuclear powered. I dont see what much advantage nuclear offer for Charles compare to Liaoning running on a coventional power.Charles de Gaulle, is nuclear powered, and CATOBAR, albeit smaller in size.
A reasonable case can be made about its superiority. Though the other side can also make a case.
But frankly, I have NEVER seen it being compared to CV-16 in mainstream US or western sources.
Your last statement is true, Catapult is a bonus for Charles but we yet to see the full potential of STOBAR. Only time will tell.
