8.8 cm R. Pz. B. Gr. 4312: Antitank Rocket Grenade

German 8.8 cm R. Pz. B. Gr. 4312: Antitank Rocket Grenade

This projectile is fired from the German 8.8 cm Raketenwerfer 43 (Püppchen—see page 352.1). From this weapon, as limited by the sight, a maximum effective range of 700 meters (765 yards) is obtained. The explosive head is identical to that of the rocket fired from the German counterpart of the “Bazooka” (page 357).

The fuze (AZ 5095) functions as follows: the force of set back causes the set-back ring to move rearward, bending the two prongs of the stirrup spring. These prongs, by engaging in the inside groove of the set-back ring prevent the ring from returning forward. Meanwhile, the striker needle is held away from the primer detonator by a flat, coiled clock spring inside the set-back ring. The clock spring unwinds, expanding against the inside of the fuze body, thus providing a slight delay in the arming of the fuze.

The propellant is a double base powder in the form of a single grain with 14 perforations. There is a hole .364 inch in diameter through the center of the grain. Three lands on the outside of the grain insure an outside burning surface. A triangular-shaped spacer holds the head igniter firmly against the quickmatch. The quickmatch fits in a slight indentation in the head igniter. The primer used in the “Püppchen” rocket is the standard No. 26 percussion primer found in many German artillery fuzes.

8.8 cm Raketenwerfer 43 (“Püppchen”): Rocket Launcher

8.8 cm Raketenwerfer 43 ("Püppchen"): German Rocket Launcher

The piece is aimed by grasping two handles fitted to the left rear of the cradle and aligning the open sights on the target. The rear sight is adjustable from 180 to 700 meters.

The launcher fires from a closed breech which is operated by a handle on top of the breech ring. Opening of the breech cocks the hammer which is held in firing position by a sear. When the projectile has been inserted and the breech closed, a squeeze of the right handle depresses the sear, releasing the hammer. A safety device fitted to the left of the firing pin in the center of the breechblock must be turned to “F” position before the launcher can be fired. An additional safety feature prevents the hammer from striking the firing pin unless the breech is fully closed. The small shock of recoil developed by the rocket gases against the closed breech is transmitted directly to the spade.

Ammunition used with the rocket launcher is a modified version of the 8.8 cm rocket projectile, having a percussion primer instead of the electric type. The rocket is fitted with a base plate with a protruding rim to seat the round in the tube. The base plate and primer are the only parts of the round which are extracted after firing.
