How flight-group limits would reshape carriers

What if naval treaties rated carriers by flight groups and speed rather than tonnage?

The incentives would shift toward efficient hulls and larger, likely twin-engined aircraft within a limited number of flight groups.

The proposed treaty would cap flight groups and speed rather than carrier displacement. Navies would exploit that definition by making carrier hulls more efficient within the permitted operating rules. A fixed number of aircraft would also reward larger twin-engined machines because each counted airframe could carry more capability. The choice of measurement would redirect design effort rather than simply suppress it.
