Mission comes before the modern Commonwealth cruiser

What tonnage, VLS capacity and sensors would a modern Commonwealth cruiser need?

Its mission must come first; the estimate for a combined air-warfare, ASW and land-attack cruiser is probably over 15,000 tons with at least 192 VLS cells.

The design begins with the operational requirement. For a combined air-warfare, anti-submarine and land-attack mission, the estimate is probably more than 15,000 tons with at least 192 VLS cells. Those are provisional design figures for the proposed mission set. A detailed sensor fit is not supplied.
