The Dwarfs have their own aircraft carriers, but these carriers are far too outdated compared to the ones used by the Tang Army.
Basically, apart from the aircraft carriers of the Tang Army, the carriers used by countries around the world are all at the technological level of World War II, without even steam catapults.
These wooden-deck carriers only have a straight flight deck, lacking advanced arresting gear and landing assistance systems.
Of course, they also do not have angled decks, and most don't even use side lifts: many carriers have lifts right in the middle of the deck, which severely affects deck efficiency.
Why not improve these issues? Because compared to the real core problems, these outdated technologies are just trivial matters.
Navies of various countries do not have reliable electronic systems that cannot be interfered with. Their communication and radar systems are practically unusable in a confrontation with the Tang Army.
