Why a Type 31-sized air-defense command ship is difficult

Can a solid area-air-defense radar fit on a smaller Type 31 or CCV-sized hull?

The radar can fit, but the complete command, computing, power, and missile system may overwhelm the small-hull concept.

A Type 31-sized hull can accommodate a capable radar and associated systems. The Iver Huitfeldt class illustrates that possibility, although Clarke describes its balance of weapons and tasks as a general-purpose fit with strong air-defence capabilities, differing from the Danish classification. The proposed British role also includes commanding multinational groups, directing carrier escorts and operating as a picket. Those duties require computing capacity and command space beyond the radar installation itself. Suggested future computing equipment adds another uncertain power and space demand. Moving radar or missiles onto accompanying uncrewed assets would still leave the command ship responsible for controlling those vessels.
