Question

How would twin 4.7-inch dual-purpose guns on British and Australian ships affect the Pacific war and ABDACOM?

Short answer

They would improve air-defence capability, but the wider effect depends heavily on what overall force ABDACOM has available.

Notes

Twin 4.7-inch dual-purpose weapons would make British and Australian ships more capable against air attack. The wider effect would depend on the composition of the force available to ABDACOM. Better guns alone do not establish how this counterfactual campaign would unfold.
