Polish tankette TK-S with 20mm FK-A wz.38 cannon

 

Would be a nice interesting addition to Germany's tier 1 premium lineup.

 

In September 1939, the Polish armored forces had about 570 tankettes, but only a handful of them were armed with 20mm cannons and could engage in equal combat with enemy armored forces.

Building of new ones and rearming of old ones started too late, as a result, only about a dozen tankettes were armed with 20mm cannons and could take part in the combat.

Despite their small size, their advantages made them one of the most valuable Polish armored vehicles. They were the first successful tank destroyers, valued for their small silhouette and agility.

 

First tests.

The first cannons to be tested in tankettes were the semi-automatic Solothurn S18-100 cal. 20 mm Swiss cannon. Bought by polish forces in 1935.

For this purpose, a makeshift mantle was installed in one of the tankettes. The tankette armed with the Solothurn S18-100 cal. 20 mm was tested in the field conditions in February 1936.

After firs trails was modernized by addition of a  purposefully build Cardan joint with a hemispherical cover. Despite positive tests, further evaluation showed that the single-fire cannon does not meet the military's taste.

 

During subsequent tests, was also checked the suitability of purchased in 1931 Oerlikon J LAS cal. 20 mm and Solothurn S5-100 cal. 20 mm, with was purchased in 1935, due to their weight and dimensions, no positive assessment was given either.

 

The military authorities, looking for a compromise, decided to purchase a universal weapon for aircraft's, anti-aircraft and anti-tank defense, at the same time a decision was made to design a automatic cannon 20mm of domestic construction. Several Polish designers started working on such a weapon by analyzing the structures of the Oerlikon FFS and Madsen 20mm auto-cannons purchased for testing.

 

As an interesting fact, it was also tested in 1936 the TK-S with a historic French 37mm short-barreled gun wz.18 Puteaux (SA-18). The heavy machine gun, which was the standard armament of the tankettes, was replaced with this french cannon, with was mounted in the standard light spherical mantle. This antique WW1 weapon with low armor penetration power was best suited in fighting machine gun nests.

The idea was abandoned for unknown reasons.

 

FK-A wz.38 NKM for Tankettes

In 1937, the engineer Bolesław Jurek from the Warszawska Fabryka Karabinów (FK, Fabryka Karabinów) constructed a recoil-operated 20mm automatic cannon, commonly known today as FK-A.

This cal. 20mm  model A canon of domestic construction offered better armor penetration than the previously tested cannons from Oerlikon and Madsen, receiving very high marks as better suited

to the needs of armored forces. As a result of the tests, the new cal. 20mm canon was adopted for the equipment of troops under the designation: 20mm wz.38 NKM.

 

The first batch of those canonns was ordered in the summer of 1938, in the number of 100 pieces. First two of trial production, were delivered to the armored forces at the end of 1938, for unknown reasons, they were tested only at the turn of January-February 1939, amazingly those test were performed in a rebuilt TK-3 tankette, though the TK-S rearmament required less changes.

 

For purpose of tankettes rearmament, engineer Jerzy Napiórkowski designed the Cardan mount with a characteristic hemispherical armored mantle.

The TK-S rearmament with a new weapon could be done at the expense of relatively small armor changes. The changes included the replacement of: the front plate with a larger weapon hole, plates above the weapon, enlargements of the rear of the gunner hatch, replacement of the front plate with hatch by elongated fixed plate. As a result of mounting a new, larger weapon in an elongated fixed plate, Gundlach's reversible observation periscope was moved to the left and the gunner's hatch was slightly smaller and its opening was possible only to the rear. The positions of the three sleeves for signal flags also had to be changed. Small changes were made to the interior equipment to accommodate 15 magazines in racks of five and the sixteenth magazine could be loaded into the weapon. A notable detail was the removal of the redundant outer pedestal of anti-aircraft MG from the right side of the hull. Thanks to the development of standard kits and the bolted armor structure, rearmament of tankettes could be performed in the field workshops.

 

The above-mentioned modernization's were made at the turn of February and March 1939.

 

Cal. 20mm cannon production and rearmament

Beginning in 1937, the military authorities repeatedly changed their decisions as to the number of vehicles that should be rearmed with new cal. 20mm canons, the range in question was between 1/3 of the TK-3 and TK-S tankettes up to all of them. The military authorities also hesitated whether rearmament of obsolete TK-3 tankettes would be advisable.

Finally, in April 1939, the headquarters of the armored forces department made a decision to rearm a bath of 100 TK-S tankettes with a first-series cal. 20mm cannons, then another TK-S in the number of 270, the TK-3 tankettes were to be rearmed as the last, which in total amounted up to 570 tankettes, under the obvious condition that the funds allow it.

 

In the third quarter of May 1939, another batch of 100 cal. 20mm cannons were ordered and the final decision was made of rearmament accounting total of 150 tankettes, with incluede 80 TK-S and 70 TK-3.

Until the outbreak of the war, probably rearmed were only 24 TK-S tankettes. There is no information whether the construction of more vehicles with 20mm cannons was completed in PZInż before or in the first

days of the war, which was theoretically possible, provided that the TK-S tankettes were assigned for rearming.

 

Combat use

Several TK-S, armed with cal. 20mm NKM were the only ones among Polish tankettes that could engage in on equal and effective fight with the German armored forces.

Their 20mm shells, under favorable conditions, especially at short distances of the battlefield, could penetrate the armor of virtually all German and Soviet vehicles of that time, including the PzKpfw IV. The main battle tank of the German campaign - PzKpfw II was similarly armed.

 

However, due to the small caliber, not all the hits or even the penetration of the armor of the tank were dangerous - sometimes they did not damage important elements or did not hit the crew. They rarely led to a total loss of vehicles, although in the conditions of the battle of the September campaign, it was also important to immobilize or overwhelm the enemy vehicle.

 

The capabilities of these small vehicles were limited by relatively weak armor, which was vulnerable to all anti-tank measures.

A significant problem was the logistics of supplies, there was a shortage of parts, fuel, and most importantly, not very common ammunition.
In the account of E. Orlik and other accounts, there are references to the use of captured German 2cm Kwk-38 ammunition, which was based on Solothurn ammunition and was also supposed to fit the Polish NKM. This thesis, which is most probable, has not been confirmed until today.

 

In view of the poor equipment of the Polish army with combat vehicles that could effectively fight the enemy's armored forces, which resulted from the financial and political situation of the country, as well as the limited processing capacity of Polish industry in the pursuit of self-sufficiency, the development of the cal. 20mm NKM and arming the tankettes with it was the right step, dramatically increasing the combat value of these vehicles

Due to Inability to quickly increase the number of light tanks and to develop and introduce into serial production medium tanks, the tankette modernization program, at least theoretically, had to allow a relatively cheap and quick doubling the number of vehicles capable of fighting of the enemy armored forces, by modernization of at least 150 of the existing obsolete tankettes armed with MG.

 

The cost of the retooling, although high, as it counts the  ⅔ of the original price of the tankette, however was anyway shorter by six times lower than the price of the new 7TP tank.

The program, although valuable and purposeful, was implemented very slowly, it struggled with delays resulting from the implementation of a new design into production, and this resulted in too few modernized vehicles.

On the other hand, a handful of Tankettes that were rearmed with cal. 20mm NKM entered the service of the Polish forces literally at the last moment before the war.

 

These agile and small-silhouette vehicles took on the characteristics of valuable tank destroyers. Of course - despite some legitimate analogy, let us remember that they were not destroyers of tanks in the sense of self-propelled anti-tank guns, that was not their purpose and organization. It is only as a result of the experience gathered during the campaign in Poland that the Germans will arm their tanks, making them less sensitive to 20mm shells.

 

Famous polish tank Ace.

The most famous action took place on 18 September near Pociecha in Kampinos Forest, when Polish units were withdrawing towards Warsaw. A platoon of three cannon-armed tankettes of the 71st Unit, sent to fight enemy armour, encountered a patrol of three German tanks of the 11th Panzer Regiment of the 1st Leichte Division on a forest crossroads. The tankettes disabled all three tanks, most likely PzKpfw 35(t), without losses. One tank got burned, and there was killed a platoon commander of the 2nd company, Leutnant prince Victor von Ratibor. There is a well-known popular myth, that all tanks were destroyed by a sole cannon-armed tankette, manned by Cadet Corporal Edmund Roman Orlik, and the remaining tankettes were MG-armed. In fact, there is another, more credible account, supported by more evidence, that there were three cannon-armed tankettes, and a major role was played by Corporal Władysław Tritt, who was awarded for his actions post-war (Orlik might have participated in this action, though). On the next day 19 September, the remaining tankettes supported Polish cavalry defending Sieraków village in Kampinos Forest against tanks of the 1st Leichte Division. According to his account, Orlik carried out short raids from earth pits and back, to the left flank of advancing Germans, and claimed to have disabled seven tanks. The Germans suffered substantial losses from the Polish defence (according to Polish reports, some 20 tanks), but exact number of tanks disabled by the cannon-armed tankettes is not confirmed.

 

Captured by German Forces

After the invasion in September 1939, most of the tankettes were captured by the German troops.

Huge numbers of the captured tankettes were non-runners, often demolished by their own crews, and even burned. However, many of them were only slightly sabotaged, broken due to lack of proper service, and even untouched, abandoned for lack of fuel. Apparently, they were put into service as support vehicles in several units at once. In the years 1940 to 1941, their use was made orderly, and the tankettes were sent for repair in workshops of Łódź (then: Litzmannstadt). Until today, the exact number of vehicles repaired and used by the occupant has not been known, and it is not even attempted to estimate this number.

 

TK-S marked by the Germans: le.PzKpfw TKS (p) (light tank TKS, "p" - Polish) was the most numerous captured vehicle used by the occupiers. Polish tankettes were mostly used as light artillery tractors or as auxiliary vehicles, also they were often used during Luftwaffe airports security operations or in actions aimed against partisans.

 

As light tractors, the tankettes served until the end of the war in some German units, especially in Norway. They could also be found in Finland and France.

 

On June 12, 1940, a security unit was established in Poland, equipped only with captured Polish equipment - Leichte Panzerkompanie Warschau, On September 3, 1940, this unit was renamed Leichte Panzerkompanie Ost., In February 1941, additionally equipped with 10 le.PzKpfw TKS (p) was transferred to Radom to train troops. There is no further information about the fate of this unit.

 

German tankettes were usually rearmed with standard German armament - 7.92 mm MG-15 or MG-34 machine guns, mounted in original Polish universal ball mantles.

There are known cases of removing weapons, then the weapon mount hole of front plate or even a entire plate was replaced with a straight flat plate with an observation slot cut out.

The standard equipment was supplemented with double exposed large reflectors on the fenders, which was strange even for 3rd line vehicles, considering that most German vehicles had headlights darkened to be invisible from the air. The tankettes in the German service were deprived of any accessories mounted to exterior armor, originally in the Polish service they have a shovel and crowbar and occasionally steel ropes.

 

The captured tankettes were repainted in the standard German camouflage - dark gray (Dunkelgrau). From 1943, they could wear camouflage in the standard tricolor German camouflage - olive green and red-brown on a dark yellow base. Also some vehicles did wear a simple desert camouflage - dark yellow (Dunkelgelb). During winter time, especially in Scandinavia, white camouflage was used. All captured vechicles wore nationality recognition crosses of different sizes and in different places. First, in 1939, they wore full white crosses. then black and white, in line with the change of German markings in 1940.

 

Armament

Serial TK and TKS tankettes were armed with one 7.92mm Hotchkiss wz.25 machine gun, mounted in a front plate, before a commander/gunner. It was a standard machine gun of the Polish armoured vehicles.

In the TK, the machine gun was mounted on a pivot behind a drum armoured cover, which was turning horizontally with a weapon. Horizontal angle of fire was 40°. Vertical angle of fire was 50°, after opening gunner's observation hatch with an upper cover of the machine gun. The machine gun had standard open sights only. Ammunition was 1800 rounds, in 120-round belts (in 15 cases).

In the TKS, the machine gun was mounted in an universal ball mounting, with telescopic sights. Horizontal angle of fire was 48°, vertical angle of fire was -15 +20°. Ammunition was 1920 rounds, in 120-round belts (in 16 cases, one case being attached to the machine gun). About 20-24 tankettes TKS were rearmed with 20mm automatic cannon wz. 38 model A (FK-A)

 

On both sides of the TK superstructure, and right side of the TKS superstructure, there was a pivot anti-aircraft mount for the wz.25 MG. It could be used only from the outside of a parked vehicle, after dismounting a weapon from the inside. There is no information if it found any practical usage. Tankettes rearmed with 20mm automatic cannon wz. 38 model A (FK-A) had this mount dismantled.

Construction:

 

Armour

Armour of rolled plates, plates of thickness 3mm up to 10mm, the 10mm plates were vertical.

• the armor of the TK-S tankette include two main parts: the upper hull and the lower hull, made of armor plates based on the skeletal structure of angles and flat bars connected with special bolts

 

 

 

• the lower part of the hull includes:
  • 25 main plates,
  • 3 plates of inspection hatches with hand grips and claw locks,
  • shutter flap plates,
  • floor flap plate,
  • 5 covers for floor inspection openings

 

 

• the upper part of the hull includes:
  • 32 main plates,
  • visor flap plates,

 

 

• The complete armor also includes fenders made of 3 mm sheet metal and a sub-engine frame

• the TK-S tankette hatches covers, are supported by a support bar, which also stiffens the structure of the upper hull

 

 

• the upper part of the TKS hull is equipped with 7 visors:
  • 2 large visors located at the rear of the vehicle,
  • 2 large visors located on the sides of the vehicle,
  • 2 small visors near the NKM yoke,
  • 1 driver's visor,
• a special insulating tape was used in all connections between skeleton and armour plates. It did prevent any resonance that could occur between the sheets and their joints while driving.

 

Chassis

On each side of the vehicle there were four road wheels, rubber rimmed, blocked in two two-wheel bogies, sprung with a pair of semi-elliptical leaf springs in each bogie. Bogies were moving up and down in runners of a suspension frame, and were sprung with a main semi-elliptical leaf spring, fixed centrally to the hull side (it was the main improvement over the Carden-Loyd suspension). A sprocket wheel was in front. At the rear there was an idler wheel, mounted on a suspension frame, with a tension adjustment mechanism. On each side there were 4 return rollers, mounted on an upper frame.

 

Tracks

metal, single-pin:  width 170 mm, pitch 45 mm, average length 124-125 links.

 

Hull

was of armour plates, screwed to a frame. A major part of the hull was taken by a common combat compartment, containing also an engine and transmission. A driver's seat was on the left, a commander/gunner's seat on the right. The seats were separated with the engine and a gearbox before it. In front part of the hull there were drive gears with a differential mechanism, under two service hatches. Behind a driver there was a vertical water radiator with a fan behind it, under a rear housing. Behind a commander there was a fuel tank and, in a rear, a battery. A cooling air was drawn through a radiator from a crew compartment and, in need, from a small bottom hatch before the radiator. The air came out by a grill in a left rear service hatch. Under this hatch there was a shaft for emergency starting the engine by crank. The cooling air also came out by a mesh above the fan housing and, in need, by a small rectangular hatch in the rear bottom vertical plate.

In the upper part of the superstructure, there were observation hatches around the vehicle. On all the flat roof above the compartment there was a common, wide, four-part hatch or two individual hatches, four-part above a driver and three-part above a commander, the earliest series of TK-S without a periscope had two four-part hatches. The hatches had pairs of leather straps attached underneath and above for handling.

In the TK-S, the driver's front observation hatch had a vision slot with a periscope. In the TKS, starting from the 54th tank, the commander had the Gundlach's reversible periscope for all-round observation, some were retro-fitted with it later. Tankettes were not fitted with a radio, except for some tankettes used as armoured draisines. Signaling in a platoon was carried out by colour flags. The TK-S had 12V electric wiring, had a detachable searchlight only. Tankettes had a single red light at the rear, on the left.

 

Engine

petrol, inline, 4-stroke, water-cooled.

TK-S (first 82 serial tanks): Polski FIAT-122AC - 6-cylinder, 42 HP at 2600 rpm, capacity 2516 cm³

TK-S (from the 83th tank): Polski FIAT-122BC - 6-cylinder, 46 HP at 2600 rpm, capacity 2952 cm³

Like the 7TP, I'd love to see this tank in the game.

Although, I would rather see it in the British tank tree a premium since the Axis (Italy) already have their little meme tankette.

 

Would I buy? Probably, yeah. ---And this is coming from someone whose been playing since 2013 and never paid a single cent on the game

[Milocat 4,854]

+1 in

-British tree (they're getting Polish ships so an argument could be made to put this beauty there too)

-German premium (captured and used)

-Future Polish tree

 

Any combination of these, including all three, would be acceptable to me.
