A capital ship's weapons reach differs from the area in which its presence can influence people. An aircraft carrier projects force through its air group, but its layout and security demands can make a close port visit difficult. A battleship may exert less distant combat power while being easier to bring alongside as a conspicuous diplomatic visitor. Operational reach and political access are different forms of naval effect.

Carrier reach versus battleship port diplomacy
Aircraft give a carrier a wider combat radius, while a battleship can sometimes create more visible diplomatic influence by entering a port and receiving visitors.
