Jagdpanzer 38(t) and its derivatives in the postwar Czechoslovak army
ST-I (Sh PTK 75 mm vz. 39/44)


After the end of the war, there were a number of abandoned and variously damaged Jagdpanzer 38(t) machines on the territory of Czechoslovakia. These fighters had been in use since the Prague Uprising by the rebel forces, and after the end of the war the looted machines were collected and almost immediately became part of the newly formed armoured units. In addition to the standard tank fighters, rarer machines such as insurgent machines from the Prague Uprising that were not armed with gun armament, or 2 cm Flak 38 auf Bergepanzer 38(t) and a sample piece of 15 cm sIG 33/2 auf Jagdpanzer 38(t).


Condition as of 1.10.1945:
21st Tank Brigade (Prague-Ruzyně) - 14 fighters (plus 5 without gun), 2 Bergepanzer 38(t). Most of the machines were serviceable.
22nd Tank Brigade (Hodonín) - 12 fighters, 1 Bergepanzer 38(t)
The brigades had two battalions each, one of which was a framework battalion.


As there was a surviving production base in the factories that produced these tank fighters, the Prague ČKD (ex-German BMM) and Pilsen Škoda factories produced these tank fighters. Both factories submitted offers to the command of the newly formed Czechoslovak army to produce and deliver several hundred machines. According to the Soviet report, up to 1,200 fighters were to be available, of which 150 could be completed within 6 months, the rest were in a work-in-progress state (45-60%). This offer was examined by the army representatives and the factory in Pilsen was visited by a military commission on 12 July 1945, which also conducted test runs with a machine armed with the StuK 40 gun (serial number 323830). After testing, this design was subjected to much criticism and the companies involved were offered to produce only 20 of the unarmed training machines to be used in tank training schools. The impetus for the development of this trainer was given to the company ČKD on 10/1945. The tank fighter was not recommended for armament.
However, after the demonstration of the tank trainer project, the consideration of supplying tank fighters was mentioned. This intention came to fruition at a meeting of the MNO (Ministry of National Defence) on 26/11/1945, when samples of both the combat and training machine were ordered. According to Confidential Order No. 1388, the tank fighter was assigned the designation ST-I and the trainer was assigned the designation ST-III. Samples were delivered in 2/1946, when the machines were sent to Milovice for testing. After testing and comments, 50 ST-III and 100 ST-III fighters and 100 ST-I fighters were ordered by the Tank Command. The company Skoda was to participate in the order by refitting the main gun armament (7.5cm tank gun vz.39/44N (modification of the booty gun for ST-I)).
As plans to arm the army with USSR-manufactured tank equipment had failed in 1946, the possibility of replenishing tank and artillery units to full strength with this particular tank fighter was considered. Initially, the artillery command rejected this type, it did not fit its requirements, but due to the fact that the required types would prospectively be delivered in as much as 6-8 years it was forced to wish the ST-I type into the arsenal of the artillery units. These fighters were to be temporarily in the armament of anti-tank self-propelled troops. The company Skoda was to supply 20 new and 87 repaired war production machines for the artillery.
Production initially concentrated on the ST-III trainer. Experience with the operation of these machines revealed a number of deficiencies that led to modifications, and subsequent production of combat machines incorporated these modifications. Fifty of the combat machines were taken over by the Panzer Army between 4/1947 and 6/1947. A further 30 ST-I vehicles for the tank troops were delivered in 12/1947, the remaining 20 fighters were delivered by 5/1948.
A series of 20 new fighters for the artillery were produced by Skoda at the turn of 1947/48. In 1948/49, repairs continued on other vehicles gradually withdrawn from the territory of the republic. Gradually it was possible to fill the numbers of anti-tank artillery regiments (each regiment had six batteries of six fighters each, making a total of 36 pieces).
At the end of 1948 the army had 234 ST-I fighters (134 in tank troops, 100 in artillery units). In the spring of 1949, their number had risen to 249 units. In late 1949, a reorganization took place and almost all ST-I and ST-III were concentrated in the 351st Tank-Mobile Regiment and 352nd Tank-Mobile Regiment. These units were under the command of the Panzer Army. In addition to these units, ten fighters and eight dispersal fighters had a Tank Apprentice in the state. During this period the official designation of the machine was changed from ST-I to Sh PTK 75mm vz.39/44, to be subsequently changed to SD 75/39-44 in 1950.
On 13.12.1950 and 14.12.1950, the ninth meeting of the DKS (artillery study commission) discussed the possibility of rearming the ST-I with the Czechoslovak anti-tank gun A 19 of 76.2mm calibre. The ČZTS (Československé závody těžkého strojírenství) was to carry out a study of this possibility by 3/1951. Representatives of the VTU (Military Technical Institute) and VTV (Tank Troop Command) were to participate in the project. The chassis needed for the project were to be delivered to Dubnica nad Váhom. The decision to stop the development of the A 19 gun put an end to these considerations. At a meeting of the VTU on 8 June 1951, the proposal to rearm the ST-I with the Soviet tank gun vz.44 of 85 mm calibre was also rejected. Another modification based on the ST-I tank fighter platform was the PM-1 flame-thrower tank project.
Among the remanufactured machines were also Jagdpanzer 38(t) Starr, which, except for the diesel-engined prototype, were re-equipped with standard cannon armament. Similarly, Bergepanzer 38(t) dump tanks were also repaired and used by the troops (the army used 10 of them).
There were 83 unarmed fighters in storage in the mid-1950s, mostly awaiting modification to flame-thrower tanks PM-1. As this project had not been completed into production form, consideration was given to rearming them into standard machines as late as 1957/58. After another reorganization in 1950, the tank-propelled regiments were disbanded and the machines were distributed in tank-propelled regiments of infantry (rifle) divisions and in batteries of self-propelled guns of infantry (rifle) regiments (10, later 6 fighters in each battery). The construction of these units was gradual; during the period when they were not assigned to any unit the machines were stored in the depots of tank bases.
The numbers and the units in which the machines were allocated were constantly changing. As of 15 March 1955, all 249 ST-Is were kept. 144 fighters were in regimental batteries, 40 in divisional tank regiments, 29 in two mechanized divisions, 21 were stored at the 2nd tank base in Žilina and the last 15 were at the disposal of the conscript organization Zväzarm. It was not until the end of 1956 that 31 fighters were cancelled in order to obtain the necessary number of spare parts. The end of these fighters came after another Army reorganization in 10/1958, when these vehicles were no longer counted on. All the vehicles were moved to the depots of tank bases where they were to form mobilization stocks, when they were to be used to form mobilization divisions in the event of war. As late as 1960 there were 207 SD 75/39-44s in service. In 1963 these machines were scrapped, but it is thought that some survived in the depots until the mid-1960s.


Individual machines were later used in the civilian sphere (e.g. as bulldozers), some were used as props in films (Tenkrát o Vánocích, Osvobození Prahy).


Delivery for Switzerland
In addition to deliveries to the Czechoslovak army, there was a trade with Switzerland, where 158 ST-I, marked with the Škoda factory mark G-13, were sent. This marking was also used during war production.


Delivery for Guinea
In 1959, three machines were donated to the first independent francophone country in Africa, the state of Guinea. Later in 1961, the delivery of 8 more ST-Is was approved. Along with them, a supply of ammunition (1,400 rounds of JO and 800 rounds of JPSv) and one Type A Mobile Tank Workshop went to this African country. This material was shipped on 20-21 July 1961 on 13 wagons to the Polish port of Szczecin. The MNO also sent technicians to Guinea to repair a trio of self-propelled guns delivered in 1959, which were no longer mobile.

Genesis of the name:

- Jagdpanzer 38(t) for the 7.5 cm Pak 39 from May 1944,

- ST-I- Tank Fighter I - from 27 November 1945,

- ShPTK vz.39/44 - self-propelled anti-tank gun - 1949 ,

- SD 75/39-44 - Light self-propelled gun on tracked chassis - late 1951.

At the beginning of the summer there were 249 ShPTK vz. 39/44, which was the highest number that remained until the end of 1951. The gradual inclusion of T-34/85 medium tanks after 1953 resulted in the reduction of the number of SD 75/39-44s.

Decommissioning of the Czechoslovak Army - 1963.

Turza, Peter.
