See 40mmSingleUS in Weapons.upc - what is the date?
40mm is available until December 1942, then 1942-12-02 will not give you anything with an upgrade in the port.
Following the attack on Pearl Harbor on 7 December 1941, the existing 1.1" (28 mm) quad mount and .50 caliber machine guns were determined to be inadequate against modern aircraft, and their replacement by 40 mm Bofors and 20 mm Oerlikon weapons was accelerated. The water-cooled version was used almost exclusively by the U.S. Navy and Coast Guard. The 40 mm quadruple mount was developed by essentially mounting two twin mounts side by side. A major improvement was the addition of power operation to both twin and quadruple mounts. Essentially all US naval mountings were twin or quadruple. 40 mm weapons were eventually mounted on virtually every naval and armed auxiliary vessel larger than a small landing craft.

Exactly when the 400mm's, began actively being used to replace the 1.1's & the .50 cal's... can't find a definitive date... though in other source material I was able to.. locate, did make mention that the older 1.1's & .50 cal's, were still in use on some ships. Just what ships, am not sure of... the article, didn't clarify on that score...

Hope this info helps...
