Damage KSU alias Š-III

Failed tanks
At the end of the 1920s, the Military Administration of the Czechoslovak Republic (hereinafter VS) decided to commission the production of two prototypes of medium tanks with a combined chassis allowing for wheeled or tracked operation. The contract for the production of the Combined Assault Vehicle (CAV) was awarded to two companies, Plzeň-based "Akciová společnost, formerly Škodovy závody" (ŠZ) and Kopřivnice-based "Závody Tatra a.s., formerly Kopřivnická vozovka". Both companies knew what was at stake because they had already experimented with combined chassis before this order. The Skoda project, with the factory name KSU (Combined Medium Assault Car, in some records referred to as KÚS), was created in July 1931. The army naming of the future Š-III prototypes is known from a preliminary order that arrived at ŠZ in September of the same year. The factory drawing dated 19.11.1931 shows a vehicle with a complexly articulated hull and a large, conical-shaped turret, allowing for the mounting of an AB/BA gun and two vz.24 machine guns. The Skoda AB/BA gun had a universal lafette and in the AB version it was a 37 mm cannon and in the BA version a 70 mm howitzer. The 2400 mm tracked chassis was equipped with two sets of wheels in the following order: front tension wheel, front tension pulley, eight running pulleys, rear tension pulley, three support pulleys and rear drive wheel. Inside the hull was a 4x2 extendable wheel chassis, the front wheels were steering wheels and the rear wheels were driving wheels. The chassis was covered on the sides with armour plates. The planned drivetrain was to consist of two four-cylinder engines, each rated at 103 kW (140 hp) in a diagonally opposed arrangement and connected by a single gearbox. The ordered weight of 12 Mg (tonnes) increased to 16.5 Mg.

The official order was not delivered to Pilsen until 29 May 1933 by MNO Decree No. 70-Taj.-V/3.sec. At that time, one of the prototypes was in a stage of high development. In December of the same year, Skoda came to the conclusion that the complex design of the wheelbase version of the Š-III was beyond its capabilities and therefore convinced the representatives of the military administration that a non-combined chassis design would be a more advantageous solution. Work on the combined version of the chassis was stopped. Its further fate is unknown. It can be assumed that suitable parts and assemblies were used in the new designs.

On 14 June 1934, the military administration sent an order to the ŠZ for the construction of two prototypes with the old code designation Š-III. This time it was a full-track combat vehicle designed to break through fortified lines of enemy defences and to fight enemy tanks. The development included a new design of a single turret for the Š-III and T-III tanks. It was produced in one piece and alternated between the prototypes of the Škoda and Tatra tanks. In 1935, the Škoda factory produced a four-piece test series of 47 mm assault guns. The first prototype underwent factory tests in late 1936. The second followed in March 1937. As a cost-saving measure, it had a hull made of unarmored sheet metal. The Š-III tanks did not make the ŠZ and took nearly five years to perfect. Still, design and driving difficulties persisted, due to the obsolescence of the chassis and the undersized power of the inadequately cooled engines. It was not until 14 April 1939 that the first prototype was taken over by the so-called Protectorate "MNO in liquidation". The second machine was handed over to Pz.Reg.57 in January 1940. In December 1940 from Kummensdorf - a Wehrmacht test polygon - the engine with number 3049 is delivered for repair. The same engine is repaired in August 1942 and from this date onwards the fate of both Š-III prototypes is unknown.

recently I got a few scans of photographs of the so-called middle tank Škoda Š-III. Now I'm looking for the archive Difrologického club original original or better quality copy. If you know the owner, let me know.

There are three known mutations of this tank:
Pity the CCI or the WGA (the original lap-band variant, unknown reg. number)
Škoda Š-III-6 (prototype six-cylinder engine, reg number: 13.638)
Škoda Š-III-8 (prototype with eight-cylinder engine, reg number: 13.639)

Other information works. Please bear with us..
