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.
