Why joint operations need larger flag facilities

How do flag facilities differ for amphibious, surface, air, and all-domain command?

Joint command needs far more specialists, screens, mapping space, and cross-domain deconfliction.

A destroyer can coordinate a single warfare area, but amphibious operations combine sea movement, ground forces, and aviation. Each added domain multiplies specialist staff, screens, mapping space, and the need to prevent friendly forces from interfering with one another. Ships such as Albion and Bulwark consequently carried substantial command facilities for their amphibious role. Unless a navy fields a purpose-built command ship such as Blue Ridge, the widest joint command functions increasingly belong ashore.
