Earlier Pershing production and American tank strength

What would change if the United States began Pershing production in 1943 rather than 1944 or 1945?

It would give American forces a stronger tank earlier, with possible benefits in both Europe and the later island campaigns.

Starting M26 Pershing production in 1943 is treated as a straightforward improvement to American armored strength. Earlier manufacture would give the US Army a heavier and more capable tank before the final phase of the European war. The tank could also have value across island campaigns, so the counterfactual extends beyond fighting German armor. The answer remains a production-timing judgment and does not claim that the tank alone would transform the war's outcome.
