Entwicklung series, more commonly known as the
E- series, was a late-World War II attempt by Germany to produce a
standardised series of tank designs.
There were to be
standard designs in six different weight classes, from which
several specialised variants were to be developed. This was
necessitated by the extremely complex tank designs that had
resulted in poor production rates and mechanical
The E-series designs were simpler and more efficient than their
predecessors, however they did not represent a significant
technological leap forward compared to earlier efforts. Nonetheless
the Entwicklung series tanks were still ahead of contemporay Allied
designs such as the British Comet and Soviet IS-2 tank, esp. when
it came to armour and armament, the E-75 & E-100 both being
significantly better armed & armoured than any Allied design
from the same period.
The E-5 was supposed to be 5-10 tonnes in weight and form the basis
of a family of light tanks
reconnaissance vehicles, tank
The E-10 design was developed as a replacement of the Panzer 38
and the designs based on it. The
38(t) chassis was enlarged and redesigned. This new design was to
be called PzKpfw 38 (d), d standing for Deutschland
opposed to (t) for Tschechoslowakei
. The designs based on
this new chassis would all be in the 10 to 25 tonnes weight
The intention was to create several new light tank destroyers as a
replacement for the Jagdpanzer 38
, as well as
a new family of Waffenträger
with heavy anti-tank guns.
The E-25 designs, in the 25-50 tonnes weight class, were to be the
replacements of all Panzer III
based designs. This family would
include medium reconnaissance vehicles, medium Jagdpanzer and heavy
The E-50 Standardpanzer was intended as a standard medium tank,
replacing the Panther
and the conversions based on these tanks.
The weight of these vehicles would fall between 50 and 75
The E-75 Standardpanzer was intended to be the standard heavy tank
to be used as a replacement of the Tiger II
. The design would have been
somewhat similar to the Tiger Ausf.B whilst being even heavier at
75 to 85 tonnes in weight. Compared to the Tiger II the E-75 had
improved allround hull armour and an even more powerful high
velocity 10.5cm gun was to be mounted along with an optical
rangefinder for increased long range accuracy.

was to be a
superheavy combat tank like the 'Maus'
developed from an enlarged Tiger II chassis. It was to be fitted
with the same turret as the Maus. Development and building of a
prototype E-100 started in 1944 but was largely abandoned after
ordered an end to the
development of the Maus.
Only the chassis was finished. It was taken to the United Kingdom for evaluation purposes and eventually
