Panzerkampfwagen I (Sd.Kfz. 101)


 

In General

   The construction of this vehicle started in the early 30’s, notably in 1932. The main purpose of this vehicle was to function as a training tank for future personnel of the Panzer Divisions. The designs and thoughts were actually based on the Russian T-27. On their turn, the T-27 was partially based on two British Carden-Loyd tanks. These were purchased in 1929. German High Command ordered four large industries to make some plans according to their needs. MAN, Krupp, Rheinmetall – Borsig and Daimler – Benz were contacted and started to make some models. In the end, Krupp was the most successful.
   There was still one small problem to start a full production. The Treaty of Versaille (28-06-1919) stated clearly that it was forbidden for Germany to have any tanks in their army (counting 100.000 men). Therefore the Germans changed the name of their new vehicle into ‘Landwirtschäftlicher Schlepper’ (La.S or industrial tractor) to conceal the true purpose…


PzKpfw I, Ausf. A 

   Germany was now steadily improving its army. Probably around February 1934, the La.S was designated for the first time as PzKpfw I, Ausf. A. Fifteen tanks were made and presented by Heinz Guderian to Adolf Hitler. Later on, he granted full permission to use some of these tanks in the Spanish Civil War (1936 – 1939). Panzerabteilung 88 and some units from General Franco used 100 of these tanks.
   But in fact the use of the PzKpfw I, Ausf. A was useless in Spain. The ‘Republicanos’ used some Russian T-26’s and BT-5’s, and these vehicles outclassed the Panzerkampfwagen I. The armour was too thin and the two MG’s were only effective against infantry. But not everything was bad however. The German High Command was able to test the armament and also some of their famous tactics (like the Blitzkrieg!)…

PzKpfw I, Ausf. B 

   During 1935 another variant of the Panzerkampfwagen I was presented. This tank mounted an improved engine (Maybach) which required a higher and longer engine compartment. The result was an extra wheel and return roller. The rear wheel was also raised off ground which improved the ride.
   Most Panzer Divisions used the PzKpfw I, Ausf. B mainly as a training tank or occasionally as a reconnaissance tank between 1935 – 1939. Starting in 1941 it was being phased out and only 74 of these tanks saw service at the start of operation ‘Barbarossa’. The other history of the Ausf. B follows that of the earlier model.


The location of this PzKpfw I, Ausf. B is unknown. Due to the white cross on the turret, we can be sure that this picture is taken very early in the war, probably Poland.

PzKpfw I, Ausf. C 

   From very early on, the German High Command realised that the Panzerkampfwagen I was of little use as a normal tank. In 1938, developments began on the tank, which led to 2 different vehicles, the first was the Ausf C. This was intended as a fast recon tank and was built by Daimler – Benz and Krauss – Maffei. Five large interleaved wheels that eliminated the need for top rollers, replaced the single row of road wheels. A 2cm. cannon replaced the left machine gun and the turret was fitted with a cupola. This improved the visibility quite well. This tank also had ticker armour.
   A small number of these Ausf. C – tanks were given for combat evaluation to the 1st Panzer Division in Russia (only 2 tanks though!) and to the 2nd Panzer Division in Yugoslavia. The remainders are believed to have been destroyed or captured in 1944 on the Normandy-front, while serving LVIII Panzer Corps.
The most remarkable about this tank is the fact that it could be transported trough the air with a Messerschmitt Me 323 Gigant.

PzKpfw I, Ausf. F 

   The second of the two new models, the Ausf. F, was intended as an infantry support vehicle. It’s heavy armour protection would allow it to stay close to the infantry when attacking enemy positions. It had the same suspension as the Ausf. C, but it was made a little bit more robust to compensate the extra weight, which was increased to 20 tonnes. Having the same engine as the Ausf. C, speed was reduced to 25km/h and range to 150km.
   Again a small number were built by Krauss-Maffei and being combat tested on the Eastern Front. The first Panzer Division was issued with eight of these vehicles.

Variants

 

Kleiner Panzer Befehlswagen I, Ausf. A/B

   This armoured command tank was built on the chassis of both the Ausf. A and Ausf. B. A fixed structure replaced the turret, which allowed room for an additional radio. This was a FuG-6 ultra short wave receiver and 20 watt transmitter. The receiver had a range of 6 miles on voice and 8 on morse. Although there was little room in the tank, there was a small map table fitted and a third crewman could operate the radios. A single MG 34 machine gun was fitted to the front of the structure.
   184 Panzer Befehlswagens were built by Daimler – Benz between 1935 and 1937. They remained in use until 1942 when they were replaced by newer command vehicles. A few of these vehicles were converted to armoured ambulances. The external difference was the removal of the machine gun and the addition of the Red Cross marking (Sanitatskraftwagen I). Both of these vehicles were also know as Sd.Kfz. 265.


On this picture the hatches on the PzKpfw I, Ausf. B for the crew members are clearly visible.

Munitionsschleper 

   When the PzKpfw I tanks were withdrawn from the front line, notably in 1942, a lot of these vehicles were converted to perform other duties. One of these vehicles was the Munitionsschlepper or ammunition carrier. In this case the turret was removed and replaced by a large metal box. This box contained ammunition for the front troops.
   The biggest advantage was the fact that these front troops never had to leave their positions. This carrier offered place for only one driver. There was no armament on board. This vehicle was also know as Sd.Kfz. 111.

Ladüngsleger 

   A second variant made from the PzKpfw I tanks were the demolition-charge laying tanks. The turret and the armament remained on the PzKpfw I, Ausf. B. However, there was a demolition arm mounted on the rear of the tank, which contained a 50kg. charge. When this arm was folded, it sat above and behind the turret.
   The main purpose of this tank was to drive near the enemy positions, mostly a bunker, so the arm could fold out and place a charge. When under fire, the vehicle was able to drive away to a safe place before the charges exploded. This variant saw most of the action during the Blitzkrieg in the west with the 7th Panzer Division.


 The folded demolition arm is clearly visible on this PzKpfw I, Ausf. B.


Flammenwerfer 

   This armoured flamethrower tank was probably the most successful conversion on the field. In many of the PzKpfw I, Ausf. A’s and Ausf. B’s, the left MG was removed and replaced with a flamethrower, model 40. The range was 30m and the fuel container was able to provide 10sec of flames. This conversion was first delivered to the Africa-Korps in the Tobruk region.

Brükenleger 

   Probably the most unknown variant of the Panzerkampfwagen I is the Brükenleger or bridge layer. This variant was unsuccessful and it never went into full production. The bridge it carried was too small to be used by other units. Only two of these were built in 1939…

Panzerjäger I 

   A successful variant of the Panzerkampfwagen I was the Panzerjäger I. When the German Army entered the Russian campaign it became clear that they were out-gunned and under-armoured. An effective short-term answer to this was necessary. An obsolete tank chassis provided an ideal mounting for the first generation of tank-destroyers. This way it was possible to deliver quantities of simple but well-armed tank-destroyers very quickly to restore the balance on the Eastern Front. However, the three-men-crew had little protection in the fighting compartment. They were protected by a five or seven sided shield which covered the front and sides. Those produced by Skoda had seven sides and those by Alkett five sides. Due to the high silhouette, the crew was even vulnerable to artillery.
   The first Panzerjägers were made from a PzKpfw I, Ausf. B, which mounted a Czech Skoda built 47mm AT-gun (German designation 47mm PAK(t) 36 L/43.4). About 200 Panzerjägers were made between 1940 and 1941. They served in Russia, France and North-Africa. They remained in use until 1943 with the arrival of better types like the Marder, Nashorn, etc…

Sturmpanzer I ‘Bison’ 

   Once again the chassis from the PzKpfw I, Ausf. B was used to mount a gun, this time it was a German 150mm sIG 33 L/11.4. This first self-propelled artillery vehicle proved to be very efficient, providing close support for infantry in the attack, or giving high angle covering fire for armoured attacks. The protection for the four-men-crew was made from three metal plates (10mm.). This made the vehicle very tall and heavy. This biggest disadvantage was its bad mobility, due to the armour which affected the suspension.
   Later in the war the Sturmpanzer II was more succesfull, as the gun was mounted on a PzKpfw II chassis. Less then 40 vehicle were made in 1940 when they saw action in Russia and on the Western Front.


The weels from the PzKpfw I, Ausf. B chassis were slightly modified to prevent them rolling when the gun fired.

Flakpanzer I 

   The weirdest variant of the PzKpfw I, Ausf. A is the Flakpanzer I. It was armed with a German 20mm FLAK 38 L/112.5 which was mounted on the hull and not on the turret. Once again the vehicle was overloaded and the engine delivered some poor performances.
   All of the flakpanzers produced (24 in total) were issued to the 614th Motorized Infantry Battalion. This unit served in the East and was one of the many German units to meet its defeat at Stalingrad. The Flakpanzer I was used in an anti-infantry role as well as the anti-aircraft role. The German cross typically appeared on the left and right sides of the vehicle, and the Flakpanzers were numbered 1 to 8. Apparently the platoons were also divided by colour with the first platoon using white, the second platoon using red, and the third platoon using yellow.

Instandsetzungstrupp I 

  The last variant of the Panzerkampfwagen I was a troop carrier and/or recovery vehicle. The turret was removed and it had an open hull which offered place to four men and a driver. There was no armament on board.
