Don´t forget the huge Elephant tank that had pistol engines powering electric engines.
You missed my point. Not all of these designs were successful. But the search for superior weapons will result in byproducts.
As for the Me 262, it was a great aircraft, no doubt. A pioneer.
Overall, we can say that we cannot convert giant heavy tanks into medium tanks. The Soviets also made ultra heavy tanks.
But the production numbers say the truth. Me 109 in the air and Panzer IV on the ground were the standard weapons.
The Me 262 was decided to be the new standard in 1945. The shift was ongoing. It could have been in 1943 but the Germans did not risk a sharp decrease of 109 output which would have been the consequence. It also can be doubted that the Me 262 would have been more successful than the Me 109. While it was a new aircraft design with jet engines, the armament was still the same: guns and R4M missiles. The great advance would have been guided missiles, though.
