Panzer III Sd Kfz 141
Panzer III was Germany's most important tank during the early war years. While
the Panzer I and Panzer II were designed as training and stop-gap machines, the
Panzer III was the first major combat tank project undertaken by Nazi Germany
and it went on to become the backbone of the German armed forces. It was conceived
as one of two basic types of main battle tanks by General Guderian. The first
to carry a high velocity gun for anti-tank work, backed up by a support tank carrying
a larger-calibre gun capable of firing a destructive high explosive shell. The
second tank went on to become the Panzer IV.
Panzer III was eventually phased out from front line service in late 1943 after
being outclassed by the latest Soviet armour but small numbers continues in service
until the end of the war.
III Ausf A (1936)
The first 10 pre-production vehicles, later to be designated
the Panzer III Model A, were completed by Daimler-Benz in 1936. Weighing 15 tonnes,
it is operated by a crew of 5 protected by 15mm of armour all round. It can manage
32kph or 20mph with an effective range of 165km or 103 miles. For main armament,
the Ordanance Department decided that for the sake of standardisation, the infantry
3.7cm KwK L/45 anti-tank gun with an internal mantlet will be fitted instead of
the higher calibre 50mm gun wanted by the Mechanised Troops Inspectorate. However,
it was also decided at the same time that the turret ring would be made large
enough for up-gunning should it become necessary. The Model A also had two 7.92mm
MG3 coaxial machineguns on the turret and a third on the hull front plate.
A feature of the Panzer III was the prominent cupola at he rear of the turret
which gave the commander very good all-round view. These
were the first in a series of development vehicles, from Model A to Model D, to
test various aspects of the design and suspension arrangements. The Model A suspension
consisted of 5 independently sprung medium sized bogie wheels with 2 return rollers.
Ausf B (1937)
The next 15 vehicles, designated the Panzer III Model B,
were completed in 1937. These vehicles were virtually identical to the Model A
except the suspension arrangements consisted of 8 smaller bogie wheels grouped
in pairs suspended on two semi-elliptical springs with three return rollers instead
of two. The Model B carried 121 rounds instead of 150 rounds to offset the extra
weight of the new suspension.
III Ausf C (1936 - 1937)
15 vehicles, designated the Panzer III Model
C, were also completed between 1936 and 1937. These vehicles were identical to
the Model B with the same wheel arrangements but they were suspended on three
semi-elliptical springs instead of two on the Model B. The weight increased from
15 to 16 tonnes due to the new heavier suspension and effective range dropped
to 105km (65 miles).
III Ausf D (1936 - 1937)
The fourth experimental variant, designated the
Panzer III Model D, had thicker armour up to 30mm as well as modified suspension
and that increased the weight to 19.3 tonnes. The same amount of fuel were carried
but in four instead of two fuel tanks. A total of 40 Model Ds were produced between
January and June 1938.
III Ausf E (1938 - 1939)
The Model E became the production version and
was designated Sd.Kfz. 141. 96 in total were produced by Daimler-Benz between
December 1938 and October 1939. They incorporate major modifications including
a more powerful 320bhp Maybach HL 120 TR engine and a completely new transmission
giving a top speed of 25mph. This variant featured the definitive six bogie road
wheels independently suspended from transverse torsion bars with three return
rollers. One of the two coaxial machineguns on the turret was deleted.
The majority of the 98 Panzer III tanks deployed during the Polish Campaign were
model E vehicles. Some of the earlier experimental machines from Model A to Model
D were also deployed but withdrew before the invasion of France. Model E vehicles
were in active service in the West in 1940, Russia in 1941 to 1942 and North Africa
up to late 1942.
III Ausf F (1939 - 1940)
The Panzer III Model F, was the first general
production model, which entered service from late 1939. 435 Model F vehicles were
delivered during sustained production between September 1939 and July 1940. The
high standard of mechanical reliability was a result of experimentation and development
through the previous models. Combat
experience from Poland and France had convinced the Germans that a more powerful
main gun than the existing 3.7cm gun was needed. But rather than delay production
of the Model F, it was decided that it will proceed with the 3.7cm until a new
gun could be developed.
III Ausf G (1940 - 1941)
The Model G was produced from April 1940 onward
incorporating a new more powerful 5cm KwK L/42 low velocity gun with an external
mantlet. This new gun was retro-fitted to many earlier variants during the winter
of 1940-41. The Model G also had a slightly modified cupola and driver's visor.
A total of 450 Model G were produced.

III Ausf H
III Ausf H (1940 - 1941)|
Between October 1940 and April 1941, a total
of 310 of a new variant, the Model H, was produced with an additional 30mm of
bolted-on frontal armour on the hull. It had a new turret and improved cupola
design with double the armour thickness and a turret basket at the rear. This
turret basket was retrofitted to earlier models. The heavier armour increased
the weight of the Model H to 21.6 tonnes which necessitated modification to the
suspension and rollers and the introduction of wider tracks (from 360mm to 400mm)
with new drive sprockets (7 rings to 6 spokes) and idler wheels to compensate.
Older models were modified to the new standards.
III Ausf J Special (1940 - 1942)
The Model J had more effective 50mm integrated
frontal armour rather than the bolted-on 30mm armour on the Model H. The driver's
visor was again revised and a new ball-mounting for the hull MG adopted. Earlier
Model J vehicles had the same 5cm KwK L/42 gun as previous models but this was
rendered obsolete by the T-34 on the Russian Front. Later Model J vehicles had
the much more formidable long-barrel 5cm KwK 39 L/60 high velocity gun. Even though
this vehicle carried fewer rounds - 84 instead of 99 - to compensate for the heavier
gun, the weight of the L/60 armed Model J still rose to 22.3 tonnes. This version
was re-designated Sd.Kfz. 141/1 and was also known as the 'Special'. It was the
most widely produced of all variants with 2516 delivered between March 1940 and
July 1942. Just over a thousand had the longer L/60 gun. The
Model J had a new storage bin behind the turret and also had triple smoke dischargers
on the forward part of the turret.

III Ausf L
III Ausf L (1942)|
The next variant, the Model L, had a modified suspension
to compensate for the fact that the new long 5cm L/60 h=gun had made the Model
J nose heavy. It also had enhanced levels of protection through the use of more
effective spaced armour (20mm) on the hull front plate and mantlet. Only 78 rounds
of ammo is carried by the Model L to offset the extra weight. 703 Model L vehicles
were produced between June and December 1942. The Heng Long Panzer III is of early
Model L specification. Later Model L Panzer IIIs have the hull side escape hatches
III Ausf M (1942 - 1943)|
The Model M incorporated minor modifications
to simplify construction and thereby increase the rate of production. The hull
side escape hatches and vision ports were deleted. This model was also fitted
with Schurzen or armour side skirting to protect the wheels and tracks from hollow-charge
anti-tank weapons. The engine access hatches on the engine deck was redesigned
and a new exhaust system introduced to allow for wading up to 5 feet. 292 Model
M were produced between October 1942 and February 1943.
III Ausf N (1942 - 1943)
The Model N was the final variant of the Panzer
III and was fitted with a short-barrelled 7.5cm L/24 main gun designed to provide
heavy close fire support to infantry. This variant was also popularly known as
the Sturmpanzer III assault tank. 666 Model N were produced between Late 1942
and August 1943.
total of 5500 Panzer III vehicles of all variants was produced. Some were converted
into armoured command vehicles and some to flame thrower tanks.
