The German flame-throwing tank has been discussed in the Intelligence
Bulletin No. 9, p. 62, but not until recently has an accurate illustration or diagram
of the vehicle become available. This apparatus consists of 2 large flame throwers
mounted on the front ends of the trackguards of a PzKw 2 tank -- the 30- to 34-mph,
12-ton vehicle with a radius of perhaps 155 miles -- now used largely for
reconnaissance purposes.
a. General
The fuel capacity for the flame throwers is about 35 gallons each -- sufficient
for about eighty projections of 2 or 3 seconds duration. Compressed nitrogen
provides the propellant, and a tank of either acetylene or hydrogen is placed behind
the projector for the igniting gas. Refuelling the flame throwers takes from one
half hour to an hour. While the range of the flame throwers is not known, it is
thought to be about 30 or 35 yards, which makes the tank a close assault vehicle,
although the armor protection for such a purpose is not impressive. The armor,
reported to be proof against 25-mm weapons at 656 yards, suggests frontal armor
of 20 + 15 mm. (.79 + .59 in) although another source gives a single thickness of
30 millimeters or 1.18 inch. A machine gun with 1,800 rounds of ammunition is
mounted in the revolving turret.
b. The Chassis
The chassis employed is that of the PzKw 2, either D or E, which are
easily recognizable by their 4 large bogie wheels, each touching both the top and
bottom of the track. The tracks are of a different type from those fitted to the
PzKw 2, model F, and have a much greater pitch -- 6 3/4 inches as against 3 5/8
inches.
The flame-thrower tank, PzKw 2 (F) Sd. Kfz.* 122 (this is the old Model B)
should not be confused with the PzKw 2 model F which is a normal type chassis
having 5 medium-sized bogie wheels and 4 return rollers. The flame-thrower
type of chassis appeared in 1939 with a normal armament, a 20-mm gun and a
machine gun mounted in the turret, but is no longer seen in this form.
c. Flamethrower Equipment
The layout of the flame thrower is shown in the lower of the accompanying
sketches. The flame thrower projectors (1) are mounted externally on the front
of track guards, protected by armored shields, with a traverse of 180 degrees.
The fuel is supplied from two tanks (2) mounted externally on the track guards
and provided with armored shields, with the nitrogen gas for propulsion drawn
from four cylinders (3) located inside the tank below the turret. Two small
cylinders (4) mounted just behind the projector turrets contain the ignition
fuel -- acetylene or hydrogen. The flame throwers are controlled electrically from
panels (5) in the turret.
d. Smoke Equipment
Since this tank is a close combat weapon, it is fitted with a smoke generator
rack (6) attached to the rear; but on each track guard behind the fuel tanks
are triple smoke generators and dischargers (7) aimed to fire forward by means
of the cables (8) controlled from the turret.
