If the carrier-based aircraft island is too big, because the carrier-based aircraft flies very high and fast, the airflow in the upper air is very strong. When the carrier aircraft flies over the aircraft carrier, there will be airflow passing over the aircraft carrier island, even if it is only a slight airflow, it will also produce huge chaotic airflow and affect the navigation of the aircraft carrier. This situation is inevitable at high altitude. Since it is inevitable, we can only minimize this adverse effect. Then, the smaller the size of the carrier island, the smaller the impact of this airflow.

Moreover, a small bridge means a small deck space, a large deck and a higher utilization rate.

Third, bridges are often integrated with chimneys. If you use nuclear power, you don't have to pump it. The bridge is naturally small.

Nuclear energy is more advanced than conventional energy.
