What if Britain had jointly modernized the Pom-Pom?

How might early-war performance have changed if the British services had cooperated from the mid-1930s to modernize the Pom-Pom?

Britain could probably have achieved Bofors-like reach while retaining Pom-Pom fire rate, improving deterrent fire and perhaps aiding other two-pounder development.

A coordinated Royal Navy, RAF, and Army program could have drawn on Britain's larger budget to approach Bofors-like reach while retaining the Pom-Pom's rate of fire. The expected improvement is in maximum range and the area of disruptive fire, with little change to the reliable kill zone. That could have helped during the Norwegian campaign, but the effect would depend on attacking pilots' morale and experience. Airfield defense might also have benefited. Any improvement to the Army's two-pounder tank gun remains speculative and would depend on how the research was used.
