What the largest Type 45 design could have delivered

What if all twelve Type 45 destroyers had been built to the largest proposed hull design?

Britain would have gained twelve exceptionally powerful escorts with much deeper missile capacity, more aviation, and better electrical margins.

The proposed arrangement has 96 air-defence cells plus 48 strategic-length Mark 41 cells, two Lynx helicopters, three Phalanx systems, and a 4.5-inch gun. Better electrical margins and only limited crew growth are expected from the larger hull. A possible sixteen-Harpoon battery is recalled tentatively. One suggested Mark 41 mix is eight anti-submarine missiles, twenty-four Tomahawks, and sixteen SM-3s. Twelve ships built this way, together with retained Type 23s, could give Britain a force of twenty-five escorts.
