In the meantime, while the Tiger and the Panther were being
developed, the existing German tanks were belatedly armed with more powerful
guns. In particular, Pz.Kpfw.IV was armed in 1942 with more powerful 75mm guns,
first 43 and then 48 calibres long, instead of the short barrelled gun of 24
calibres, which had been used in German tanks since the Grosstraktoren of 1929.
In contrast, the Soviet Army armed its tanks with progressively longer
barrelled and, therefore, higher velocity 76.2mm guns. Thus the early Russian
tanks, including some of the BT, were armed with guns only 16.5 calibres long
but the final versions of the BT and T-28 medium tank were armed with guns 26
calibres long while the original versions of the T-34 and KV had guns of 41.2
calibres. However, when the Pz.Kpfw.IV was finally rearmed with the 75mm L/48
gun the latter proved to have an armour piercing capability considerably
greater than that of the Russian 76.2mm guns of 41.2 calibres and as good as
that of the 85mm gun with which the T-34 was eventually armed.
The armament of the most numerous German tank during 1941
and 1942, the Pz.Kpfw.III, was also improved. The Pz.Kpfw.III was conceived as
a light tank to be used alongside the medium Pz.Kpfw.IV (1.76). However, it had
the same general layout, five-man crew and almost the same weight as the
Pz-Kpfw.IV, which was extravagant in relation to its original armament of a
37mm gun. After the 1940 campaign in France it was rearmed with a 50mm gun 42
calibres long, which at short range could penetrate more armour than the short
barrelled 75mm gun of the contemporary Pz.Kpfw.IV. However, its performance
proved inadequate against the frontal armour of the Russian T-34. In
consequence it was rearmed again, being fitted in 1942 with a 50mm gun 60
calibres long, the armour piercing performance of which was at least comparable
to that of the Soviet 76.2mm tank guns of 41.2 calibres. In the end it was
armed with the same 24 calibre 75mm gun as the original Pz.Kpfw.IV. This should
have been done from the start and might have led to the merger of the two types
into a single battle tank that could have been produced more efficiently and
employed more effectively.
As it was Pz.Kpfw.III was best used when its chassis became
the basis of the turretless Sturmgeschütz. The latter was conceived as an
assault gun for infantry support but in 1942 it was rearmed with the same
long-barrelled 75 mm gun as the Pz.Kpfw.IV. This turned it not only into a tank
destroyer but also into a very effective turretless tank and it was used as
such by the Panzer divisions when there was a shortage of turreted tanks.
Ultimately the number of Sturmgeschütz built on the Pz.Kpfw.III chassis
amounted to 9409, which was more than the total production of any German tank.
Sturmgeschütz mit
8.8cm PaK43/2 (Sd Kfz 184)
History: During
the development of the Tiger(P) and Tiger(H), Hitler had agitated for a turret
design which would be large enough to mount the 8.8cm KwK L/71. This had not
materialized and on 22 September 1942 it was decided that a StuG with 200mm
frontal armour and the long 8.8cm gun should be immediately designed, with the
Tiger( P) as the basis, and part of the Tiger( P) production diverted for the
vehicle. Alkett was to design and produce the Ferdinand, with Nibelungenwerke
supplying the completed chassis. Despite the shortage of suspension parts and
lack of test runs, on 6 February 1943 Hitler ordered that 90 Ferdinands were to
be supplied for the front as quickly as possible by all available means. This
resulted in the order for Nibelungenwerke to complete the Sturmgeschutz
Ferdinand instead of Alkett. All 90 were completed by the end of May 1943, in
time for use in the summer offensive at Kursk.
Specific features:
The hull of the Ferdinand was that of the Tiger(P), but with 100mm plates
bolted to the front, and an addition to the rear to support the superstructure
and vent cooling air for the electric motors. The superstructure housed the
long 8.8cm gun in a limited traverse mount. No secondary armament was mounted
until late 1943, when those returned from the front were modified to carry a
hull machine-gun. The superstructure was also changed at this time to provide
the commander with a cupola. Forty-eight Ferdinands were so modified.
Combat service:
Ferdinands were issued to Panzerjagerabteilungen 653 and 654 in April and May
1943. These units fought at Kursk during the limited offensive and helped plug
holes in the line for the rest of the summer and autumn. The units were pulled
out late in 1943 to overhaul the vehicles, after which, the 653rd
Panzerjagerabteilung was re-equipped and a separate company was attached to the
614th Panzerjagerabteilung.
Jagdtiger (Sd Kfz
186)
History: Early in
1943, orders were given to design a heavy, self-propelled anti-tank gun, by
mounting the 12.8cm gun on a Tiger II chassis. A wooden model of the enormous
vehicle was displayed on 20 October 1943, and the finished prototype, in April
1944. Two Jagdtiger (Nos. 305001 and 305004) were built with the
Porsche-designed longitudinal torsion-bar suspension. This proved
unsatisfactory and delayed production until the Jagdtiger had been redesigned
with a torsion-bar suspension. The initial series was for 150, but an order
issued in October 1944 stipulated that when these had been completed,
production capacity was to be used for building the Panther. However, this was
reversed in January 1945, with an order to continue the assembly of Jagdtiger
as fast as possible. A Jagdtiger mounting the 8.8cm L/71 was designated Sd Kfz
185, but this never went into production.
Specific features:
The Jagdtiger had the same suspension as the Tiger II, but its hull was
lengthened. The superstructure had a very box-like appearance, with the sides
being formed by the continuation of the upper hull sides. The hull machine-gun
mount was retained in the hull front, as secondary armament to the 12.8cm
PaK44, mounted in the superstructure front.
Combat service:
The Jagdtiger was issued to only two combat units, Panzerjagerabteilung 653 and
schwere Panzerabteilung 512. The 653rd was employed on the Western Front during
the Ardennes offensive, and later with the 512th in the defence of Germany
proper, in such actions as that of the Remagen Bridgehead on 10 March 1945.
