No, we have amphbious transports docks for that, currently HMS Albion and Bulwark. I believe those carriers were built with the harrier in mind, which of course did not need the long landing space of other aircraft. But even our privious large carriers such as the Ark Royal were not as big as the USN ones. When the Phantom was taken into service the Ark had to be modified to operate such a big plane and the plane had to be modified to operate from such a small deck.
The new carriers are the biggest ships even built for the RN.
