Distributed air defence multiplies hull and support demands

The proposed air-defence system separates missiles, sensors, and command between Type 91, Type 94, and Common Combat Vessel hulls. Each additional ship needs propulsion, and redundant missile and sensor platforms increase the number of hulls required. Maintenance teams would still have to reach uncrewed vessels, probably by helicopter, while satellite communications, radio, and laser links replace the hardwired connections inside one destroyer. Storm damage and collisions raise further questions about reliance on automated damage control. A sufficiently capable command vessel may consequently need much of the intended Type 83's capability. Delivering six CCVs by 2035 is judged implausible with a clean-sheet design because the yard would first need new production tooling. An Arrowhead 140 derivative offers a more plausible route through the existing Type 31 production system.
