In the midst of space warfare, the most critical capability of an aircraft carrier is to safely deploy various types of space fighters, from the small Wind Falcon to the large Dragon Elephant, via the launch deck to the vicinity of enemy warships. This allows the fighters to fully utilize their potential and strike against enemy ships.
Otherwise, the exchange of fire in space can easily extend out to tens of thousands, even hundreds of thousands of kilometers, which would require the fighters to fly for an inordinately long time on their own.
If refined further, a towing system would be equipped that could pull back the fighters from a considerable distance that has been locked in by the towing force before the battle.
However, this is considered a luxury.
After all, according to the style of the Empire, sometimes treating the fighters launched for missions as disposable, no different from how other warships view their fired shells, is not surprising.
