How VT-fuzed pom-poms change wartime air defense

Proximity fuzes for 40 mm ammunition could greatly increase British anti-aircraft lethality.

Question

What if Britain had VT fuzes that fit pom-pom ammunition during the Second World War?

Short answer

British ships would kill many more attacking aircraft, and the pom-pom might outperform Bofors without VT fuzes.

Notes

VT fuzes for British 40 mm ammunition would make the pom-pom much more dangerous to attacking aircraft. German and Italian aircraft losses would rise, especially given the mounting's rate of fire. The advantage could also change comparisons with Bofors. If Bofors ammunition lacked the same fuze, the pom-pom might perform substantially better.
