What if germany had adopted an e plan in 1937. So instead of a bewildering array of types, the focus was on 5 standard catogories with simplification of design and production. The E plan in 46 was focused on this
Of course below was based upon info gained from years of war, but the concept of focus on production, cost, standardization, and efficiency. This was the plan for 46.. If this was the concept from 36 or 37 for tanks and also perhaps aircraft ?
1946 E plan. Wiki
E 10: Light tank/tank destroyer weighing between 10-25 tons. The E 10 was to be built by Klockner-Humboldt-Deutz Magirus AG in Ulm in very large quantities. It was to replace the
Panzer 38(t),
Jagdpanzer 38(t) and the various Waffenträgers based on their chassis. One interesting feature of the E 10 is that it was to have “kneeling” suspension, that would have allowed it to minimize its profile while sacrificing mobility. Only a wooden mockup was built.
E 25: Medium tank/tank destroyer weighing between 25-50 tons. Designed and produced by Alkett, Argus, Adler and Porsche, the E 25 was to replace the
Panzer III,
Panzer IV,
Sturmgeschutz III,
Jagdpanzer IV, as well as provide a medium scout vehicle.
E 50: Medium tank weighing between 50-75 tons. Designed by Argus, Auto Union and Adler. The E 50 was essentially a
Panther streamlined for production. It might have used the
Schmalturm and 8,8 cm PaK 43 L/71.
E 75: Heavy tank weighing between 75-100 tons. A
Tiger II streamlined for production, in all technical respects, the E 75 would have been identical to the
King Tiger. Briefly before the War ended, a Sturmgeschutz E 75 was proposed, but did not have the chance to be developed further.
