Section VI. ARMORED VEHICLES
4. Heavy Tanks
a. Pz. Kpfw. PANTHER. (1) General. In this tank, probably the
most successful they have produced, the Germans have departed from their
customary lines and sought inspiration in the design of the Russian T34. The
tank weighs about 50 short tons, and the effectiveness of its armor is enhanced
by the fact that most of the plates are sloping. It has powerful armament, and
has a high-powered engine which gives it a maximum speed of about 30 miles per
hour. Internally the Panther is arranged in the standard German manner, with
the driver's compartment in front, the fighting compartment in the center
section, and the engine at the rear.
The Panther's design employs the double torsion-bar suspension. There are
eight double, interleaved, large Christie-type bogie wheels. Each set of bogie
wheels is mounted on a radius arm on the projecting end of a torsion bar which
is coupled in series to a second one lying parallel to it. This ingenious device
has the effect of doubling the length of the torsion bars.
The Panther first was met in action on the Russian front in the summer of
1943. Originally designated Pz. Kpfw. V, its nickname, Panther,
was, adopted as its official nomenclature in February 1944. The latest version
to appear is the Model G. The principal reasons for the success of the
Panther are its relatively high speed, maneuverability, dangerous armament, and
good protection.
Variants of the Panther tank which have been identified are the commander's version, the
wrecker tank (Bergepanther), and the self-propelled gun Jagdpanther, which
consists of the 8.8 cm Pak 43/3 or 4 on the Panther chassis.

b. Pz. Kpfw. TIGER. (1) General. This tank, originally the
Pz. Kpfw. VI, first was encountered by the Russians in the last half
of 1942, and by the Western Allies in Tunisia early in 1943. Its colloquial
name, Tiger, was adopted officially in February 1944. The current version
is Model E.
Unlike the Panther, the Tiger is designed on familiar German lines, but all the
dimensions are increased. The main armament is
the 8.8 cm Kw.K. 36, which is essentially
the 8.8 cm Flak 36 adapted for turret mounting. The
mounting of such a heavy gun has raised considerable problems of rigidity, and
consequently the hull is constructed of large plates entirely welded
together. The superstructure is made up in one unit, and welded to the
hull. The turret wall is made from a single large piece of
armor, 82 mm thick, bent into a horseshoe shape. Further, all the
armor plates are interlocked, in addition to being welded. The armor of the
Tiger, at the time of its appearance, was the thickest ever to be fitted on any
German tank, the front vertical plate being 102 mm thick and the
hull sides 62 mm.
The suspension, which employs interleaved, Christie-type bogie wheels
with a very wide track, is reasonably simple and is an effective solution
of the suspension problem for such a large and heavy vehicle.
The Tiger engine requires very skilled driving and maintenance to get
the best performance, and in the hands of insufficiently trained crews
mechanical troubles are apt to appear. This characteristic has been the
tank's principal disadvantage.

c. Pz. Kpfw. TIGER, MODEL B (KING TIGER). (1) General. This tank
is a development of the Tiger along the lines of
the Panther and with a new main armament, the 8.8 cm
Kw.K. 43 (L/71). The armor is as
thick as that of the Tiger—in some parts
thicker—and the improved design and the slope given to the majority
of the plates (as in the Panther) give the tank vastly improved protection.
The King Tiger is a tank designed essentially for defensive warfare or
for breaking through strong lines of defense. It is unsuitable for rapid
maneuver and highly mobile warfare because of its great weight and
low speed. To accommodate the gun the turret has been made
unusually long in proportion to the total length of the tank. When
"buttoned up" the tank is extremely blind, and this is one of its
weakest points.
Since the King Tiger first appeared in August 1944 in Normandy,
modifications have been made in the turret to eliminate the excessive
plate-bending involved in the original construction. The King Tiger
virtually is invulnerable to frontal attack, but the flanks, which are less
well protected, can be penetrated by Allied antitank weapons at most
normal combat ranges.
