I know when M1A1 started production. What's relevant is when it started being delivered.
"War" will be over in couple of weeks no matter what. So you won't have time to order crash production of any tank or airplane, or even order a increase in ammunition and spare parts production and have them ready before the war is over.
Even fully conventional (something that is 100% impossible) within couple of weeks everyone would be out of ammo and spare parts and fuel, and also the active forces numbers would have dropped a lot by then. Modern high intensity war, as would have happened in Germany, is rather brutal even if fully conventional.
