As the core equipment of the modern navy, the scale of aircraft carriers is not as large as possible, but is constrained by a number of key factors.
First of all, the cost of building and maintaining an aircraft carrier is directly related to its tonnage, and too much will lead to a sharp increase in financial pressure, including large steel consumption, advanced system integration, complex electronic equipment configuration, and the overhead caused by the increase in the number of carrier-based aircraft.
Second, the technical level faces serious challenges, giant aircraft carriers need breakthrough technological innovation in terms of structural strength, stability, power propulsion and electric power**, and at the same time, their large size may also affect maneuverability and maneuverability in the marine environment, especially in confined sea areas or reduced flexibility in emergency evacuation.
In addition, ultra-large aircraft carriers have extremely high requirements for global supply and logistics support systems, which may not only limit access to some ports due to draught restrictions, but also increase the difficulty and cost of replenishment.
From a strategic point of view, the actual combat effectiveness of an aircraft carrier does not depend entirely on its size, but on how it is integrated into the entire combat system, as well as the combat effectiveness of carrier-based aircraft units. The size design of the aircraft carrier needs to take into account the safety of take-off and landing of carrier-based aircraft, the efficient layout of the operating space, and the ability of supporting equipment such as catapults and arresting cables.
Therefore, the design of aircraft carriers should seek the best balance between military needs, economic benefits, technical feasibility and tactical flexibility, rather than one-sidedly pursuing the maximum size of aircraft carriers, but maximizing their strategic value through scientific and rational ship matching and aircraft carrier battle group construction.
