A 6-inch and 128-cell Type 45 concept

Would the proposed 6.1-inch gun and additional 76 mm weapons have been worthwhile for Type 45?

Yes. The preferred Type 45 would combine a 6-inch gun, several 76 mm weapons, layered close defense, and roughly 128 VLS cells.

The proposed fit combines a 6-inch gun for surface and shore work with overlapping medium-calibre air defence. A 96-cell mixture of Sylver and Mk 41 launchers sits forward, with another 32 cells aft for roughly 128 VLS cells in all. The design also leaves room for sixteen Naval Strike Missiles. Three 76 mm weapons and three Phalanx mounts create crossing defensive arcs around the ship. This is an ambitious personal concept rather than a description of the Type 45 as built. A twelve-ship class would spread development cost and provide wider fleet coverage.
