Klöckner-Humboldt-Deutz KHD S3000/SSM Maultier (Sd.Kfz 3c) mit 3.0 cm Bordkanone MK 103 (Behelfslafette) - case report

Achtung, Soldaten!!!

    The objective of this report is to show you another product of German ingenuity: the Maultier trucks. Let's get to know the least famous and least numerous among them, but without a doubt, the most robust and beloved by soldiers, in its class: Let's talk about the Klöckner-Humboldt-Deutz KHD S3000/SSM Maultier (Sd.Kfz 3c)
Expectations and reality...

History of the vehicle
    One of the characteristics of the Second World War was the mobility of the armies involved, compared to the First World War. Most nations involved in the conflict since the outbreak of hostilities had a large number of vehicles to support their armies on the move. And Nazi Germany stood out among all in this regard. The vast majority of trucks employed by the Germans were 3-ton rear-wheel drive vehicles (generally designated as S models) and 4x4 trucks were designated as A models. 
   An example of these trucks was the KHD S3000, produced since 1940 at the Klöckner-Humboldt-Deutz factory in Ulm. This truck was a 4x2 like most of its Opel and Ford siblings, but featured a robust Deutz 4-cylinder diesel engine, which was quite strong and economical, and was very popular with soldiers.

    The KHD S3000 4x2 trucks were widely used by all German arms until the end of the war, in all Theaters of Operations: North Africa, Russian front, in Italy, France, until the defeat in Berlin. 
     During 1941 German Army discovered that their wheeled transport vehicles were unsuitable for the muddy rasputitsa conditions that marked the beginning and the end of the Russian winter. Only halftracks like Sd.Kfz 250 and Sd.Kfz 251 were able to operate in these conditions, but removing them from their operational purposes for supply duties would have been unworkable.

    Instead, Germany began to build half-tracked versions of their 3 ton trucks Opel, Ford, Klöckner-Humboldt-Deutz and 4,5 ton truck Mercedes-Benz by removing their rear wheeled axles and replacing it with a sub-chassis with tracked suspension, adapted to the normal "wheeled" chassis. 
    In the case of 3-ton trucks (Opel, Ford and KHD), this sub-chassis featured in its anterior portion the adaptation of the truck's original differential with sprockets adapted to the brake drums of the original wheels (to allow the service brakes to be maintained), suspension bogies copied from the British  Horstmann type suspensions, used by Universal Carriers and a idler wheel at the rear. The front axle was connected to the normal gearbox using a very shortened card axle, minimizing adaptation and production costs. The vehicle used tracks from the (now discontinued) Panzer I light tanks, which made logistics and maintenance even easier. These 3 ton trucks with rear tracked undercarriage were officially designated Lkw 3t' mit Gleiskette SSM Maultier (Mule) in the German army, with the designations Sd.Kfz. 3a (Opel), Sd.Kfz. 3b (Ford) and Sd.Kfz. 3c (KHD).

    The Mercedes-Benz 4,5 ton trucks they used a more robust suspension (with wheels and tracks), derived from the Panzer II, with the designation Mercedes-Benz L4500 R Maultier - Sd.Kfz. 3/5 or Sd.Kfz. 4.

    They were extremely useful in extreme terrain conditions, both due to irregularity and quality. During these periods, the logistical issue almost collapsed, as single-traction trucks and even 4x4 or 6x6 trucks struggled just to move, making it almost impossible to transport supplies and goods to the armies. The Maultiers moved slowly, with the top speed was around 35 kilometers per hour. In order to preserve and save the rear drives, the drivers usually drove even slower. 
    Klöckner-Humboldt-Deutz built somewhere between 1,740 and 2,500 haltracks vehicles (sources are not exact as to the number), using the normal 4x2 KHD S3000S truck as the basis for this conversion. All KHD Maultier were produced between 1942 and 1944, under the designation Klöckner-Humboldt-Deutz KHD S3000/SSM Maultier  - Sd.Kfz 3c.

of German armaments, the monthly production figures were publicly

in response to the challenges of the Russian Front.

    The KHD S3000/SSM Maultier had a ground clearance of 25 cm. It could wade through waters up to a depth of 70 cm. The five litres four-cylinder diesel engine generated a continuous power of 70 HP. For a short time, a maximum power of 80 HP could be reached.

History of the 3,0 cm Rheinmetall-Borsig MK 103 Bordkanone
    The Rheinmetall-Borsig MK 103 ("MK" - Maschinenkanone) was a German 30 mm caliber autocannon that was mounted in German combat aircraft during World War II. Intended to be a dual purpose weapon for anti-tank and air-to-air fighting, it was developed from the MK 101. Although, as the name suggests, it was developed to be an aircraft "on-board gun" (Bordkanone), it was also widely used as a light anti-aircraft weapon, thanks to its high muzzle velocity, high rate of fire and accuracy, in addition to being a low weight weapon (due to its aeronautical origin) being easily adapted to different mounts and land vehicles.

    Compared to the MK 101, the  3,0 cm Bordkanone MK 103 was faster firing, and was originally intended to develop a higher muzzle velocity than the MK 101. Unlike the MK 101, the MK 103 used a belt feed, allowing it to potentially carry a larger ammunition load.

from 10.(Pz)/SG 9 (Schlachtgeschwader 9) on the Eastern Front.

Sequence from the previous photo:

   The MK 103 used electrically primed rather than percussion-primed ammunition. The operating mechanism differed from the recoil-operated MK 101 in that it used a combination of gas and recoil operation. After firing, gas pressure served to unlock the breech, while barrel recoil was used to cycle the action (eject spent cartridge and load a fresh one).

    Because of a combination of lower grade steels and lighter components, the mechanism of the MK 103 was not as strong as the MK 101. To counteract this weakness, HE ammunition with a reduced load of propellant was used, resulting in a loss of about 100 m/s in muzzle velocity compared to the MK 101, but the rate of fire was increased. The MK 103 entered service in 1943 as the main armament of the Hs 129 B-2 ground-attack/tank-destroyer aircraft, mounted on the underside of the fuselage in a conformal gun pod.

Henschel Hs129 B-2 in the field.
   The original specification for the MK 103 called for it to fit inside an aircraft's engine mounting (possibly as a Motorkanone, firing through a hollow propeller hub), but it proved to be too large and heavy to fit into small fighters like the Bf 109. If mounted elsewhere, such as in the wing, the asymmetric force of the cannon's recoil tended to yaw the aircraft's nose to one side. 
    The only known usages of the MK 103 in a Motorkanone installation were in the Dornier Do 335 Pfeil and the Focke-Wulf Ta 152 C3

      The 3,0 cm MK 103 gun was also tested in the unsuccessful Messerschmitt Me 410 Hornisse heavy fighter, in dual mounting in the nose of the aircraft, but it was not accepted as standard armament.

  Projectile weights for the MK 103 3,0 cm guns were 330 g  for the HE/M ammunition and 355 g for APCR ammunition. The armour penetration for APCR ammunition was 42 - 52 mm / 60° / 300 m or 75 - 95 mm / 90° / 300 m.

    The design of the weapon is quite simple and reliable. But as we saw before, the main disadvantage was the strong shock loads during the operation of automation and excessive recoil, which limited the use of 30 mm guns as part of the armament of single-engine fighters. Production of the MK.103 was carried out from mid-1942 to February 1945, and a significant number of unclaimed 30-mm guns accumulated in the warehouses of the Luftwaffe, which became the reason for their use in anti-aircraft installations, being installed on various stands, bases, land vehicles, boats and ships, using single or quadruple mounts.

The kits
    My intention is to build a KHD S3000/SSM Maultier with a light anti-aircraft gun in the cargo area, as a field adaptation. The idea would be to locate our vehicle on the German front, in the desperate days of the Spring of 1945, when the Allies dominated the skies and the need for aerial protection was of utmost urgency. The chosen gun is a 3 cm Bordkanone MK 103, mounted on a naval  stand and adapted for use on this nice diesel half-track. I made a profile of the project concept:
The ultimate goal of the project...
    To do this, we will use the following "cake recipe":

The fearless bald one, with his newest challenge!!!
Kojak rules!!!

Following the booklet...

Gentlemen, start your engines!!!!
The diesel powertrain is big!

Building the chassis...
Man, the squaring is essential here...

     And now, the first frisson: in my kit, one of the jerry-can racks was missing (the left one). The bag with the sprues came sealed and without the part inside. I think the loss was at the time of packaging, at the factory. But there's no point in crying... let's do something from scratch...
The part G34 is missing!!
Lets scratch one!!

Plasticard and patience (with a sharp n° 15 scalpel and metal ruler...)

Now, we can transport our precious reserve diesel!!!

Building the front parts of the truck...

And, again, everything is well aligned and squared...

Engine in position!!!
    Building the rear suspension structure. Interesting how the Maultiers used the rear wheel as a structural part of the drive sprockets. The use of drum brakes is a touch of genius, when it comes to use and simplicity...

Notice the front axle and the "rear" axle,
connected with gearbox by a short cardan shaft.

following the markings. One thing that's bothering me
are the vinyl tires... too much like a toy..
    The wheels on the Horstmann bogies are correct, but they are those of the spoked model, more commonly found on early models. And I would like something more late, end of the war. The pressed wheels are more from that period of maximum production... In the photo below, you can see a comparison between the spoked wheels of the kit and the pressed wheels I would like to use...

and the pressed wheels
    I remembered a resin conversion kit manufactured here in Brazil, which I acquired a few years ago and was forgotten somewhere in my catacombs... After a dusty and exciting search, I found the little kit from Electric Products. The kit consists of two complete front wheels, with military-style tires, eight pressed-type wheels and two pressed-type idler wheels. Bingo!!!

And our girl with the new "feet"...

Notice the new front wheels in resin, glued in position...
    Now, it's time to install the tracks. The kit provides a very detailed set of links and length (L&L) and links by links (LBL). The L&L sectors are 2x30 (upper portion), 2x20 (lower portion) and 4x6 ("angled" portions) segments each, in addition to 40 individual links for the track construction.
The shoe store provided by ICM...
    The instructions call for two 8 LBL segments to be made for the sprocket drive and idler wheel curves. But I'm going to make a small modification to this sequence, as it's possible that I need another link to the track: I decided to simulate the weight of the track on the return rollers, as nothing is more unrealistic than a track tense like a ruler with the vehicle stopped... Even more so with this type of suspension. The idea is to simulate the fit using the weight of the upper portion of the track (L&L of 30 links). Here is the methodology:
Track segments that we will use. I will glue 7 LBL together,
with one more "waiting" for its turn to enter the system.
As I use plastic welder cement, I keep a certain flexibility
in these LBL segments...
    The first thing I do is glue a 6-link L&L segment to the front portion of the 20-link L&L segment. Pay close attention to the direction of the links on the track!!! After this gluing (at an approximate angle of 45°, I support this union on the front curvature of the front wheel of the front Horstmann bogie. This is to match the junction of two straight segments in the "curvature" of the wheel. See the photo:
The 6 L&L segment (red arrows) fitting perfectly into the curve of the wheel,
glued to the front portion of the 20 L&L segment.
A small amount of superglue between the resin wheels and the plastic links
makes everything stable... Fitting the front portion of the 6 L&L
onto the teeth of the sprocket drive is essential...

The two L&L segments in position (yellow)
We need 8 links LBL for perfect adaptation to the sprocket drive (green).
This "limit" is important for the step we are going to do now: simulating the weight
 of the tracks on the return rollers...
    In short, after gluing the 20 L&L segment with the 6 L&L segment (step 1) and the 8 individual links (8) onto the sprocket drive (step 2) ,we fit the 30-link L&L segment to the edge of the track on the sprocket drive. With the segment resting on the return rollers, we mark with a marker the portions of the links that rest on the return rollers (step 3). These markings (green in the diagram below) are the indicators where we will make the curvatures on the L&L track. I used the handle of a normal brush to simulate the presence of the return roller (step 4)  and "curved" the two ends of the 30 L&L track downwards (step 5). I did this at the two markings on the return rollers and between these "folds", I used the tips of my fingers to shape the track upwards(step 5, again), making the characteristic snake shape (step 6). This now heavy-looking track was glued to the previous portion of the last link of the sprocket drive and to the idler wheel, at the rear, in addition to small portions of glue on the return rollers. See the diagram below and the subsequent photos:

into LBL, heavy... Easy as slapping a drunk!!!

In real life: The 30 L&L segment folded into the return roller markings (green circles)...
I just used a little pressure, without needing hot water or anything...

and the standard (straight and boring: blue arrow...).

Now, I glued the 6 L&L segment and the final LBL parts...
Franz and Fritz are very, very satisfied with the end result!!

And now, repeat the entire process on the right side of the Maultier:
notice how the straight and stretched 30 L&L segment looks unnatural...

Superior German Engineering!!!
Plastic tracks very similar to Friuls!!!
Franz almost didn't believe that this would be possible...

...but Fritz was confident!
He knows Kojak's tricks!!
    And just to complement the task, we will take care of the cabin, so that it can be painted...
Cabin, under construction.
    Well, while the truck rests a bit, let's build the Bordkanone MK 103. It's my first experience with this manufacturer, the 16.02 Model Kits, but the kit is very detailed and well injected. Let's follow the instruction booklet....
Building the 30mm gun is simple and quick...

The pieces are delicate and therefore very fragile...

It may seem repetitive, but squaring is essential!!!
    One flaw (in my opinion...) is that the cannon does not have the possibility of vertical or horizontal drift movement. I tried to do something with these two axes, but the gun's damping system (the springs...) prevent vertical movement. I even made springs with copper wires, but the space and small size of the parts involved and the space available in the weapon prevented my poor attempts. What was left was the trunion of the gun being replaced by a steel wire (see pic below). At least it became more resistant. The solution here would be for the manufacturer to send a very thin steel spring, like AFV does with its Churchill AVRE mortars, but I think this is very difficult to do.
Replacing the trunion with a metallic wire.
The cannon moved vertically, but...
    Now, the horizontal drift is another thing: I replaced the conical base pin with a hole and made a through pin, with a rivet-like head made with the heat of a flame, passing through the base of the weapon and being able to be cemented into the conical base. of the weapon. As a result, our Bordkanone had a 360° drift.
The "standard" pin in the top of the conical base...
Hmmm...not good!!
    Converting the conical base from "male" to "female". Removing the pin and opening a hole in its place. The new pin in green and the male pin of the conic base, in red...
Note the flat head of the pin (green), shaped with a heated tool.

The base pin, cut and in its place, a perforation (red right)
 with the same diameter as the Plastruct pin (green).
The base of the gun was also drilled and countersunk (red left),
 so that the head of the pin is not so prominent (green circle)...

Pin inserted through hole in gun base and conical base.
I placed a drop of glue inside the conical base, to avoid any risk
of glue running onto the gun bases.
The head of the pin was almost flat, thanks to countersinking...

And the cannon with 360° drift. Kojak is a hardworking guy...
    And speaking of base, I resisted the temptation to use the flat circular base of the weapon's conical strut. As this conical "neck" features nuts connecting this cone to the circular base, I thought what it would be like in real life: the circular base would be cast into a concrete base, almost impossible to remove...But the conical neck could be detached of this concreted circular base. Therefore, we will provide a spare steel plate (a remnant of schürzen, which some Stug lost somewhere...) with good thickness, cut it with oxyacetylene and install the conical neck on it by bolts, so that everything can then be screwed onto the body of our Maultier. Simple and coherent!!!
The new scratch base (green) and the kit base,
suitable for concrete (red).

And a dry-fit of the gun in the cargo bay of our Maultier.
Notice the wooden boards (rectangular pieces of Plastruct),
closing the spaces on the sides of the cargo body (red arrows),
to prevent the gunners from putting their feet in these spaces,
when the sides are lowered and transformed into shooting platforms...
    Now, let's decide on the colors and markings for our Maultier, as we have to paint the cabin so it can be closed. As I said, at the beginning of the project, the idea would be to place our Maultier at the end of World War II, as a weapon adapted against the massive presence of Allied aviation in the skies over Germany. And here's what we decided to do: Klöckner-Humboldt-Deutz KHD S3000/SSM Maultier (Sd.Kfz 3c) mit  3.0 cm Bordkanone MK 103, belonging to the 11. SS-Freiwilligen Panzergrenadier-Division "Nordland" (11th SS-Volunteer Panzergrenadier Division "Nordland"), fighting in the Battle of Berlin, in the last desperate days of April, 1945.
