Pz. Kpfw. III (Fl. W. 41): Flamethrower Tank

Pz. Kpfw. III (Fl. W. 41): Flamethrower Tank

The flame-throwing tank, put into service in 1942, consists of the standard Pz. Kpfw. III tank equipped with a flame projector instead of the usual tank gun. A machine gun is mounted coaxially in the turret and another is ball mounted in the front plate of the hull. Its road performance will approximate that of the Pz. Kpfw. III tank.

The flame tube, which looks like an ordinary cannon, contains 3 jets. The barrel behind the curved position of the armored shield is 134 cm long and at the flame end is 12 cm in diameter. Movement of the gun horizontally and vertically is controlled by two handwheels within reach of and to the left front of the tank commander. Propulsion of the liquid fuel for the flame thrower is achieved by means of a centrifugal pump driven by a small two-cylinder gasoline engine which is located in the engine compartment to the left of the tank motor. The fuel tanks are located beside the tank commander to the inside right and left side of the tank chassis.

Pz. Kpfw. II (F) (Sd. Kfz. 122): Flamethrower Tank

Pz. Kpfw. II (F) (Sd. Kfz. 122): Flamethrower Tank

The flamethrower tank, Pz. Kpfw. II (F) is a conversion of Pz. Kpfw. II, Models D and E, which employed the four bogie wheel suspension, and should not be confused with the Model F, which utilizes the five bogie wheel type of suspension. The road performance of the flamethrower tank approximates that of Models D and E.

The flamethrower projectors, having a range of about 35 yards, are mounted in small turrets set well forward on each trackguard. The turrets have 180° traverse while the projectors themselves have a limited elevation. Fuel is supplied from two tanks, provided with armored shields, which are mounted externally on the trackguards, and by compressed nitrogen from the four nitrogen cylinders located inside, below the turret. The tanks have a capacity of 35 gals. each. Two small cylinders mounted just behind the projector turrets contain acetylene, which is used for fuel ignition. The flamethrower is controlled electrically from panels in the turret.

Since this equipment is essentially a close-combat weapon, the tank is liberally fitted for smoke production to screen its movements. Not only is the normal smoke generator rack fitted at the rear, but there is on each trackguard a triple smoke generator discharger, aimed to fire forward, and bowden cable controlled from the turret. Armament also includes a machine gun on a ball mounting in the turret.

m. Flammpanzerwagen (Sd. Kfz. 251/16): Armored Flamethrower Vehicle

m. Flammpanzerwagen (Sd. Kfz. 251/16): Armored Flamethrower Vehicle

This flame-throwing vehicle is employed in association with more heavily armored panzer units. It is an adaptation of the medium armored personnel carrier on which have been mounted the various items of equipment required.

There are two large projectors mounted well back on either side of the vehicle in V-shaped shields. Each of these has a nozzle .55 inch in diameter, and a traverse of 160 degrees. The third flamethrower takes the form of the cartridge ignition projector used in the small portable flamethrower Model 42, on the end of 33 feet of hose, connecting it to the propulsion unit and fuel tank through the back of the vehicle. The nozzle of this projector is .28 inch in diameter.

Fuel propulsion is by a pump driven by a small gasoline engine supplied by a 5 1/2-gallon tank which will run the engine for two hours. One hundred and fifty-four gallons of fuel for the flamethrowers is carried. This allows about eighty bursts of one or two seconds’ duration each.

The effective range of the large flamethrowers is about 40 yards; that of the portable unit about 30 yards.

1,850 gallons of fuel are carried in the three 3-ton lorries of platoon transport. This is sufficient for two refuels for all six flamethrower vehicles of the flamethrower platoon.

The crew of the vehicle consists of one vehicle loader who also acts as wireless operator and machine gunner, two flamethrower operators, and a driver.
