Yes but they're not the answer to all [prayers that many people think they are. Their rebuilds to incorporate angled decks and steam catapults should be easier and therefore cheaper and the problems that arose in the 60s with bigger aircraft shouldn't be as acute compared to the Eagle and Ark Royal due to their size and speed. But even they will require replacement at some point in the 70s or early 80s after 20-30 years of service. Perhaps this decision could be made by the Conservative government from 1970 and perhaps the bigger carriers could see CVA01 not designed with too many tricks, but stuff like stagflation, the winter of discontent and the withdrawal east of Suez would still happen unless these 2 ships fundamentaly altered the Suez crisis.
