German cross  The Panzerschreck ammunitionGerman cross

A study of types, construction and effect of ammunition

 
The Raketen Panzer Büchse Granat 4322 (winter 43/44 version) as it was pictured in the instructional slide series for the Panzerschreck

The Panzerschreck as a weapons-system was entirely dependent on the ammunition for performance. And as the launcher was continually improved, so was the ammunition. At the same time, the ammunition was always the weak point of the Panzerschreck system, all up until the end of hostilities. To better understand the functioning and construction of the grenade I will divide it into its logical parts and describe them separately. Only this way will it be possible to understand the difference between the different models. For those that can't be bothered to read the full text I will give you a shortlist of the different official models right here.



Model designation Type Remarks
8,8 cm R PzB Gr. 4320 Bl Live rocket, dummy warhead For target practice
8,8 cm R PzB Gr. 4322 Standard grenade 3 varieties with different motors
8,8 cm R PzB Gr. 4329 Ex Dummy grenade Drill practice only
8,8 cm R PzB Gr. 4990 Bl* Live rocket, dummy warhead For target practice
8,8 cm R PzB Gr. 4992* Standard grenade Improved contact system
8,8 cm R PzB Gr. 4999 Ex* Dummy grenade Drill practice only
*It is still unclear if these grenades indeed were manufactured at all. Apart from the one illustrated in manual D 1864/6 no specimen, packing or marking has been found to prove that they indeed were industrially manufactured.

The main parts & function
The grenade consisted of 4 main parts, of which (broadly speaking) two and two worked together. The red line below illustrates this.

The igniter was plugged manually into the connector box on the rear end of the launcher. When fired, it would ignite the rocket motor, which in turn would propel the entire grenade forward for 3 meters before it was completely burnt out. The grenade would now have a velocity (V0) of 100 meters per second and would be in "free flight". On impact the fuze would be set off, detonating a small blast cap that would send a "spit-back" to ignite the booster, which in turn would detonate the shaped charge in the back off the warhead that would form a jet that would punch through the armour.

Let's break it down!


The Igniter
The igniter would use the current produced by the Stoßgenerator to ignite the rocket motor. The igniter consisted of a bakelite plug that was glued into the venturi (jet nozzle). A steel top disk with a crimped edge sealed off the end to make it "weatherproof". The actual electric igniter (Raketenmotoranzünder) protruded from the front of the bakelite plug. One of the wires coming out of the top disk was soldered to the rocket body inside the tail drum. The other wire was soldered to a metal pin placed in the wooden handle.


The wooden handle was a square piece of wood with a circular depression on one side on the middle (to avoid damaging the wires). The handle was taped across the rear end of the tail drum where it would protect the igniter during transport.


An improved model was introduced with the Wintermunition 1944/45. The wooden handle was reduced in size and form to a tapered design and was repositioned inside the tail drum.  

The picture at the right above shows a prototype of the 8,8 cm R Pz B Granate 4992 with the second model igniter handle stored inside the tail drum. This igniter was also used on the 8,8 cm R Pz B Granate 4322 with the Wintermunition 1944/45 motor

When the rocket fired, the igniter would be spit out of the rear, and according to the manual D 1864/1 “The ignition device will fly 30 m to the rear."
Normally, the wire attached to the wooden handle would snap, and the wooden handle would have to be removed manually before a new could be inserted.


Ukraine, December 1943. The new weapon has been fired on a range, but the soldier shouldering it hasn't removed the wooden handle that is still plugged into the connector box

The second model of the grenade, the 8,8 cm R PzB Gr. 4992, had an integrated contact system that made the wooden handle superfluous when the grenade was fired from the 54/1. This system is described in details on the page about the R Pz B 54/1
There is no evidence to support the theory that the 
second model grenade was ever mass-produced.

The Rocket motor
The rocket motor was the only difference between the 3 production varieties of the 8,8 cm R PzB Gr. 4332 (apart from the improved wooden handle). The different versions of the motor could be identified by the marking on the motor tube.
Name Temperature range Marking Remarks
Wintermunition 1943/44 -40 to +30 0C Arkt.
Sommermunition 1944 -5 to +50 0C Unmarked
Wintermunition 1944/45 -2 to +25 0C Arkt. 44/45 New wooden handle

The motor consists of a steel tube with a closed front, 40 mm in diameter, with a 2,5 mm thick wall that is threaded in each end. The tail drum is welded to the venturi, which in turn is screwed on at the end and holds the internals of the rocket motor in place.

The above photo is a manipulation to show the construction of the rocket motor and the components


The first two models of the motor were identical in construction. Inside the removable venturi the motor has a spacer ring (1) at the very end that holds everything in, and in the right position. In front of this is a grid (2) constructed from 4 pieces of flat iron pressed together. The grid will ensure that the fuel rods don't travel backwards and block the ventiru. There are 7 fuel rods (3), 6 forming a full circle and 1 rod in the centre. The fuel rods are made of Diglycol and are 10,5 mm in diameter and 200 mm long, and have a centre-hole of 6 mm. The central fuel rod has a 6mm celluloid tube inserted that is slightly longer than the fuel rods, which ensures that it rests inside the centre grid in each end (not visible in the picture above). The celluloid tube contains a small black powder pellet in both ends and a thin strip of Diglycol powder between the pellets. In front of the fuel rods another grid (4) holds the central fuel rod in place and ensures that there is sufficient space between the fuel rods and the ignition charge (5). The ignition charge is made of black powder and is held inside an aluminium disk with a celluloid front plate.
In order to build up enough pressure to work properly the fuel rods must burn up from the front to the rear. The electrical igniter will set off the small black powder pellet in the celluloid tube placed in the centre fuel rod. The fire will then travel inside the rod until it reaches the black powder pellet in the other end, which will in turn set off the ignition charge. This will be sufficiently strong to ignite all 7 rods at once, which in turn will burn up and become gas. The gas escaping through the venturi will in turn push the rocket forward.
In recoil-weapons, like a howitzer or a mortar, the pressure acquired from a propelling charge is built up behind the projectile, and held by the barrel-walls. The Panzerschreck motor would have to be strong enough to contain all the gases on the inside and only permit them to exit through the venturi. This was one of the Panzerschrecks weak points!
High-pressure meant better accuracy and performance. Too high pressure would result in a burst motor and subsequently a destroyed launcher with injury to personnel.


This picture shows what happens to the motor when the built up pressure is more than it is constructed for. This one was dug up in the former Soviet Union

 All ammunition faces the same problem. The hotter the powder - the higher the pressure - different ballistics. The warmer the rocket motor was initially, the higher the pressure got when it ignited! In the operator manual it was advised to keep the ammunition stored in heated bunkers in the wintertime until it was needed. This gave a much better hit probability. A grenade that had been overheated (reached a temperature above the allowed temperature range, for example due to direct sunlight exposure) would be unsafe to fire. The grenade could be used again, once it had cooled down to the certified temperature range.

The first 15.000 grenades manufactured had to be restricted to use between -10 and +30 degrees C. (These were not meant for operational use, so correct "type or designation" for this ammunition is not known). The first production ammunition was the "Wintermunition 1943/44". This was certified for use between  -40 and +30 degrees C, and was marked "Arkt" (Arctic/winter) on the motor. The next version was the "Sommermunition 1944" that was certified for use between  -5 and +50 degrees C. This ammunition had no special marking on the motor.  The difference between the first two production models appears to be the composition of the fuel rods.

The last production version was the "Wintermunition 1944/45" which was marked "Arkt 44/45" on the motor tube. This motor was certified for use between -25 and +25 degrees C. Although the temperature range was just as limited as earlier models, this version had improved performance and would now be useable out to 200 meters. (This version also introduced the new wooden handle for the igniter). 

The internals of the motor was redesigned after the two first models. The 7 fuel rods were replaced with one single stick. This was moulded in the form of a “spoke wheel” with one central tube (the axis) surrounded by 14 channels. This gave a maximum of surface area and low thickness of the fuel, to ensure the best possible contact with air for the combustion process. The ignition charge at the top of the tube appears to have been considerably increased in size as well, and replaced the upper grid.


This is the only known picture of the propellant stick for the Arkt 44/45 motor. The "spoke wheel" design and the central igniter tube are both visible

The new design would give a more efficient combustion, resulting in a higher V0 (Velocity at the starting point). With a higher V0, the grenade would go further with better accuracy, and if the combustion of the motor was completed before the grenade left the launcher it would be possible to discontinue using the shield. It seems unlikely that this was achieved with the Wintermunition 1944/45, but the introduction of the grenade offered an increased combat range resulting in a new front sight. This sight has been described in detail on the page about the sights.

 A new version of the motor (codenamed “Panzerschreck III”) was under construction but never saw production before the end of hostilities. It weighed 5,2 kg and had a V0 of 140 m/s. According to reports from the Waffenprüfung it delivered a “punch” from the back blast that was unacceptable. Tests were conducted with launchers that got a cone added to both the front and rear end, but these “inventions” only added to the recoil. No further details about the motor are known.

The Fuze
When the rocket motor had burnt out it was all down to free-flight and the fuze. The fuze used on the Panzerschreck Granate was the AZ 5095/1 (Aufschlagszünder 5095/1). This fuze was not very well suited for the grenade, but was the only model used for the duration of production. The AZ 5095/1 was issued with a manual safety pin with a hole in the end for a wire & lead seal. Due to the construction of the fuze it was vitally important that the safety pin had an intact seal! If ammunition was received without the safety pin in place, or even just missing the lead seal, it was not judged as safe and should under no circumstance be handled or used.
Let us try to understand the workings of the mechanism:
The safety pin (colored grey) must be removed before the grenade is inserted in the launcher. The safety pin has only one function; to hold the arming collar (colored yellow) in position. With the safety pin gone the only thing holding the arming collar in position is a thin brass disk (colored blue) that has two fingers bend upwards that rests against the bottom of the arming collar.
When fired the acceleration of the rocket will start the unarming process of the fuze by holding the arming collar back (the brass fingers will be bent down). This will release the spiral spring (colored green) that rested coiled up inside the arming collar. When the spring unwinds it will be resting towards the outer wall of the fuze, and the striker (colored pink) with the firing pin will have free access to strike the Duplex detonator, only held in place by the creep spring.

According to the manual D 1864/6 the grenade can be shot through light camouflage (foliage) up to 3 meters away, as the AZ 5095/1 fuze would be "Maskensicher". So after 3 meters of free flight the arming collar would be fully retracted and the spiral spring would have had time to completely unwind.
So, if the safety pin was removed and the round wasn't used you could in theory put the safety pin back in again and all was fine. But if the loader had dropped the grenade or even just bumped it there was no way of knowing if the arming collar and spiral spring were still in place. Shooting a grenade without the safety features in place would be very dangerous. The acceleration of the grenade could be enough to set off the charge.
A document issued as an annex to the Heerestechnisches Verordnungsblatt in August 1944 mentions the trouble with the safety. "All Panzerschreck grenades found with a missing lead seal, no matter what cause, is not judged as safe to use and should be destroyed by technical personnel."
Although only one type of fuze was used with the production grenades other varieties was tried. The problem was first of all the (lacking) safety features. A lot of testing was done to try to utilize a base mounted-detonator (much like the Panzerfaust) based on the Bd. Z. 5142 (Boden Zünder 5142). It was renamed twice, and ended up as A.Z.J.M.12 on 4. February 1945. This was the final approval from the WaA for use with the Panzerschreck grenade, and all production drawings were ready. It is doubtful that it ever made it to production though.
  

The Warhead

The actual warhead was a classical shaped charge. The front portion of the head was hollow with the fuze mounted in front at the correct “stand-off” length required to get the maximum effect from the explosive charge. The rear end of the warhead held the explosives inside an inverted bottle-shaped liner. The liner had a hole in the bottom to allow the “spit-back” from the detonator in the fuze to hit the booster that was embedded in the explosives. The booster was the Kleine Zündladung 34. A wooden dowel was inserted in the very end of the warhead and acted as a thermal insulation between the rocket motor and the booster.

The shaped charge would focus the enormous pressure from the explosive’s energy on the liner, driving this inward so that it collapses on its central axis. The result is a collision that forms and projects a jet of metal particles from the liner that moves forward along the axis at 7000 meters per second. The extended nose section of the 4322 gives the correct stand-off distance. This allows the detonation to fully build up the kinetic energy enabling the jet to deliver its punch with maximum effect against the armour. If the grenade is set off before it hits the actual armour the effect will be less effective. The jet would punch a hole in the armour that was considerably smaller in diameter than the 8,8 cm of the grenade, but the size of the impact hole had no relation to the effect of the grenade on the other side of the armour. The actual jet would be dispersing even as it went through the armour, leaving a wider hole on the inside. This added to the effect of the punch, as particles (and parts) of the armour would be torn off on the inside and act as projectiles inside the tank. In addition the heat and pressure from the jet would set off ammunition and wound or kill the crew. The Panzerbeschußtafel 25 describes the effect as follows:
The 8,8 cm R Pz B Gr 4322 will detonate at impact with the armour-plate – outside the plate – and will punch a hole through it with the explosive charge. The hole will always be smaller than the calibre.  At the same time shrapnel flying sideways will have an effect against the accompanying infantry or troops riding on the tank. The effect against the armour will be the same at all relevant ranges. It will only be weakened by a lowered angle of impact.
Observe the effect of the rocket! All hits haven’t got a devastating effect.


These pictures are taken from a film that shows the effect of a Panzerschreck rocket against a thick steel plate. Conducted by the Wa.Prüf des Heereswaffenamt on Hillersleben proving ground, December 1944. The entire video is available here.

 The effect of the warhead had nothing to do with the velocity of the grenade on impact. It depended solely on the effect from the shaped charge. The “angle of impact” was important, but this is simply because a lower angle of impact makes the armour thicker and lessens the effect from the jet.


X represents the armour plate. A is a grenade with a 90 degree impact and B represents a grenade with a 45 degree impact. Grenade B will have to punch through a considerable thicker piece of steel than grenade A.

The 8,8 cm R Pz B Gr 4322 would penetrate 17 cm of armour, more than enough to knock out all known Allied tanks. The important part was to hit the hull or tower, and not external parts like the road wheels, tracks etc. The effect of the grenade against other targets would be very limited and the manuals clearly advised against it. The D 1864/1 states: Use (the 8,8 cm R PzBGr 4322) only against tanks, due to a low fragmentation effect it is not effective as a high explosive grenade. The ability to penetrate armour is a result of the shaped charge effect.
Experiments to improve the warhead were conducted until the end of hostilities. Different shapes of the liner, alterations to the explosives and adjusted stand-off length were all tried out but never incorporated in the production. The casing for the warhead came in two different models. The first model consisted of 3 (outer) parts, while the later model only had two (outer) parts. The 3-part version had a belly-belt that was crimped in both ends, while the 2-part version simply crimped the front in place. It is not possible to tell which version was manufactured when, as it appears to have been linked with the manufacturer rather than as an improvement.

All contemporary German pictures and drawings show grenades of the upper type.
In this case the upper is a Arkt 44/45 grenade and the lower is a Arkt grenade.


The picture above is from the Recognition handbook for German ammunition, published by the SHAEF in April 1945. Both models of the warhead are visible.
The box is for Sommermunition 1944 judged by the unreadable label attached to the front
.

The explosive used in the warhead was 700 grams of Hexogen and TNT in a 60:40 mix. This mixture had the code number "97", which could be found ink-stamped on the head.



The 8,8 cm R PzB Gr. 4992

This model was an improvement over the 8,8 cm R Pz B Gr 4322. It utilized the same warhead, the same fuze, the same igniter and the same rocket motor as the 8,8 cm R Pz B Gr 4322 Arkt. 1944/45 version, but it had an improved tail drum that incorporated a contact ring. This would enable the loader to skip the manual step of plugging the rocket igniter to the connector box during loading. This could only be used on the R PzB 54/1 that was rebuilt with a new model of connector box. Read more about this on the page concerning the R PzB 54/1
Although the new grenade was pictured (probably a prototype) in the manual D 1864/6 as early as 1.12. 1944 and it was officially introduced for service in the Technische Heeresmitteilungen on 15 January it never saw service. According to a progress report from the
Wa.Prüf des Heereswaffenamt from 14 January 1945 ...all technical problems have now been solved and production will commence. No tail drums with the contact ring, no packing crates with the appropriate marking and no paper labels proving that it ever existed (beyond the picture above) have surfaced so far. All evidence present suggests that the technical problems with the contact ring were solved too late, and it never made it to the production lines.

Markings, paint and manufacturers
The grenades in existence today on collector hands are mainly “water-finds”. Painted metal that has been submerged for several years will normally be a lot darker than it was originally. In addition it will to some extent have “bubbles” on the paint surface. Contemporary pictures of the paint show a very light color with a high contrast to the ink-stampings. The only original example I have been able to study is a cut-through model in original color at the FMU. This one has a ordnance green head with bluish faded ink-stampings that are now hardly readable. Not adhering to the regulations, but still undoubtedly original.



The Paintwork on the 8,8 cm R Pz B Gr 4322 was regulated in the Heerestechnische Verordnungsblatt 1. September 1944: "Geschoßkopf feldgrau, Brennkammer phosphatiert, Leitwerk Schwarz." (Warhead Fieldgray, Motor phospated, Tail drum black). 

The head had the grenade number in large black numbers applied with ink on two opposing sides. In addition an array of a numbers, a filling date, a code for the explosive filling and so on could be found on the “belly belt”.  The WaA approval stamp is normally in white paint on the lower portion, together with a makers code and a lot number.



The rocket motor had the model painted on in white paint; “Arkt.” or “Arkt. 44/45”. In addition the maker and year could be found in white paint. 


An Arkt. 44/45 motor manufactured by fsv in 4 (late 1944)

The top of the rocket motor would normally have the maker code stamped into the metal, along with two WaA-prüfung approval marks.

The tail drum was usually unmarked, but at least one Arkt. 44/45 grenade has been found with a squared maker code and year painted in white. I assume that in this case the tail drum and motor was manufactured by the same company and that this marking replaced the painted maker marking on the motor itself.

Packing material for ammunition


The
8,8 cm R Pz B ammunition came in pairs in a wooden box with the designation “R-Munitionskasten 4322”. The box had a plywood lid, dovetailed corners and a handle that consisted of a rope. Metal was only used on hinges, clasps, nails and screws. Internally a set of 5 spacers kept the grenades firmly in place to avoid damage during transport. The box would weigh 4,4 kg empty and 11 kg with complete contents. The external finish came in a wide variety of unpainted, Dunkelgelb, light grey, charcoal black or Dunkelgrau, with a light finish being the norm.


A rainy day on the range. Note the Dunkelgrau ammunition box with white stenciled text.

The markings found on the box always followed the same pattern. Some markings were standardized on all boxes and others would depend on the ammunition it contained.


Heeres-munition Gesamtgewicht 11 kg” (Army ammunition, combined weight 11 kg) would be stamped in two lines on the left front and on the lower left of the lid. Sometimes the weight was a part of the stamp, and sometimes it had to be filled in manually like this one.


“R Mun 4322” was painted on in a large font centred on the lid. This abbreviation stood for “Raket Munitionkasten 4322” (Rocket ammunition box 4322) and must be considered a “general description” of the contents, since the specific abbreviation for the ammunition was 8,8 cm R PzB Gr. 4322. All boxes appears to have had the same text, even the boxes containing the 8,8 cm R PzB Gr. 4320 Bl, the training grenade with the dummy warhead. As mentioned above, no box has ever been found for the 8,8 cm R PzB Gr. 4992, but if such a box in fact existed it would most probably have been marked as above, since the marking specified the box, and not the contents.

As discussed above, the rocket motor came in 3 different varieties. In addition a dummy grenade with a live rocket was also supplied for target practice. To ensure that the operator knew what type of ammunition or what type of rocket motor he would be shooting, each box was clearly marked with a symbol or text. The Technische Heeresmitteilungen from 01. September 1944 and 15. January 1945 gave a detailed description of the size, form and position of each symbol. These were also listed in the H.Dv 1864/6 from 01.12.1944.


This tabular describes the model, the marking on the box, the marking on the rocket motor and the temperature range.
 

Examples of all the variations described above. Note that the Arkt 44/45 box is a recycled Wintermunition 1943/44 box with the ring covered by paint.

 

The dummy grenade with live rocket motor is not described in regards to marking practice of the ammunition box, but a surviving specimen shows that it was simply marked “Bl” (for Blind) in black instead of the other symbols. The “R Mun 4322” was kept, even though the box contained a 4320 grenade!

Assorted paper labels were glued on the box according to the contents of the box. The same labels would appear on the outside of the box as well as on the inside of the lid. The main label described the contents in detail as follows:

 
1. 8,8 cm R Pz B Gr 4322 Designated abbreviation for the grenade
2. A.Z. 5095/1 
Aufschlagszünder 5095/1. The fuze model.
3. 97 Code for the explosive mixture. 700 grams of Cyclonit/Hexogen and TNT in a 60:40 mix
4. 7R  7 Röhrchen. Number of tubular powder units
5. Digl. R.P. -9,5 -(200*11,6/5,6) Rocket motor contents. Diglycol Röhren Pulver (
Tubular powder). -9,5 - (200*11,6/5,6) length of the fuel sticks, outer diameter and inner diameter
6. rdf. 1944/3 rdf. is an abbreviaton for Reinsdorf.  1944/3 is the LOT number.
7. Tpn. 17. 4. 44. A. Heeres Munitionsanstalt Töpchin
17 April 1944
8. DR. Diglycol Röhrenpulver

 A separate label gave a warning about the temperature restrictions for the ammunition in the box it was glued to.




When comparing these labels with the tabular above it is obvious that there must have been differences between the manufacturing batches of the grenades as well, as some of these temperature ranges differs from the listed variations. The top of this section show a Dias of a full, open box. The label is hard to read, but the temperature range is easy to see; -40 to +15. Yet another variation!  

 
"Visierstellung bei allen Temperaturen wie für Wintermunition bei - 250 C". This label can be found on the outside (only) of boxes with Sommermunition 1944, and gives instructions for aiming with this ammunition compared with the Wintermunition 1943/44. 

 
This (partial) label is just a transportation tag that gave details of the shipment from 
Heeres Munitionsanstalt Töpchin.

The inside of the Wintermunition 1944/45 box had a special label that stressed that this was a new ammunition and that it had to be used with the new sights. See the page about the sights for more details.

The cardboard wrapping

A new type of packing material for the Panzerschreck rocket was announced in the manual H.Dv 1864/6 published on 01.12.1944. It states that “A cardboard tube for one grenade that can be carried on the back will be issued in the future instead of the ammunition box”.  

No pictures or specimen of this ammunition wrapping has survived, so it is unclear if it was manufactured at all. The access to all types of raw materials was dwindling together with Das Reich. The cardboard wrapping idea was definitively put to production to save wood.
The picture above shows a (very) late war cardboard wrapping box for 8 cm Mortar ammunition. The 3-round box for factory-frontline transport was normally made of wood. It is not unlikely that the production of a similar packing material set was made for the
8,8 cm R PzB Gr. 4322.

Makers of ammunition and ammunition parts


The main manufacturers of ammunition for the Panzerschreck appear to be WASAG and Eibia. These are the only codes that appear on the labels inside the packing crates. But the components for the grenade were manufactured by a large number of subcontractors.


This "Arkt" grenade can serve as an example. Fuze made by gcy, warhead body made by fcc, rocket motor made by fsv, rocket fuel unknown, igniter made by am, booster unknown and finally filled by rdf.

The following list are codes and manufacturers associated with the manufacture of the
8,8 cm R PzB Gr. 4322. There will be a whole lot more added as I find them.

The following pictures are samples of box labels from different lots.
 



The last label is the only one with "2 Stück" (2 pieces) I have found so far. Unsure if the label on the outside was identical with the one on the inside. If not, then this is probably the standard "outside of the box" label.

 
The box above is a standard "Luftdichter Pulverkasten 03" (Airtight Powder box 03), and it was used for transport of components between the factories making parts for the rocket. This one contained 420 rocket fuel assemblies for the Wintermunition 1944/45 (Pressling was the compact "wheel" type).

For details about transportation of the ammunition see my new article about the transport of the Panzerschreck
