The combat capability and existence value of the Super Carrier are questioned because its combat capability has relatively declined fundamentally. Under current technological conditions, it cannot provide necessary support for ship-borne aircraft with greater combat radius, larger payload, and faster speeds, making it difficult to complete increasingly challenging combat tasks.
Actually, a comparison will make things clear.
Take combat radius as an example. During the Second Global War, most heavy bombers had a combat radius between 1000 to 3000 kilometers, while ship-borne fighters at the same time could reach 800 to 2000 kilometers. Several shipborne aircraft in the later stages of the war even reached 2500 kilometers, capable of escorting bombers throughout the journey. Obviously, even compared with heavy bombers, ship-borne fighters at that time did not suffer in terms of combat radius.
