Izumo enlarges the Hyuga concept from 19,000 to 26,000 tons at full load and adds the ability to operate F-35Bs. The planned air group discussed here combines seven ASW helicopters, two search-and-rescue helicopters, and twelve fighters. In a gray-zone confrontation, long-range sensors can leave uncertainty about maritime patrol aircraft derived from civilian airliner designs and flying similar patterns. Fighters can approach and identify an aircraft before the group commits to an attack. The comparison with the Royal Navy's Invincible class emphasizes limited air defence, strike, and support, with the absence of a ski jump further constraining the strike potential described here. These capabilities support a force screening Japan, its sea lines of communication, and other ships.

Izumo adds fighters for identification and limited air defence
F-35Bs give an Izumo group a way to identify ambiguous aircraft before firing, while helicopters retain the ship's sea-lane screening role.
