Hello everyone,
following is the account of all we know about the Czechoslovak hightier TVP project, at least the rough outline. It is clear that proper research into this will take more time, but we’ll get there.
Summary
The development of post-war Czechoslovak tanks started very soon – by the end of 1945, where VTÚ (Vojenský Technický Ústav – Military Technical Institute) filed a report to MNO (Ministry of National Defense) and to the local Red Army committee on the state of current tanks and other armored vehicles development. This led to series of proposals I will deal with later, culminating with the TVP project (Tank Všeobecného Použití – Tank for General Use). TVP was heavily influenced by both Soviet (cast turret) and German development (gun mount, welded turret version, mantlet) and drew from the best of both worlds.
1945-1946 specifications and first Škoda proposal
Based on the abovementioned report, on 17.10.1945, the 1st Department of Army HQ submitted its ideas about the new medium tank to VTU. The requirements included:
- 30-33 ton weight
- 5 man crew
- 8,5 to 10,5 cm gun with 80 shells and with a coaxial Vz.37 or BESA heavy machinegun, with another MG of the same type used as bow machinegun (3600 rounds for both MG’s)
- armor plates – RHA plates of following thicknesses: 65mm, 40mm, 30mm and 20mm
- 450mm clearance
- ground pressure of 0,5kg/cm3
- a diesel engine
- road speed of 50 km/h
Interesting fact is that the vehicle design itself was to be selected only after selecting the gun itself (the tank was supposed to be “built around the gun”), based on comparison trials of all the guns available. In December 1945 to February 1946 (Dubánek here mixes the dates, an obvious typo – I fixed it), the VTU representatives considered the 88mm German AA gun (the AA role is specifically mentioned, but it’s possible the author has the KwK 43 L/71 in mind – in post-war Czechoslovakia, the PaK 43 and 41/43 were adopted due to the lack of native or Soviet AT guns as PTK vz.43 (protitankový kanon – AT gun, vz.43 – 1943 pattern) with shell velocity of 1000 m/s or a 105mm gun (900 m/s) to be viable, as during tests, both were able to penetrate 100mm of armor at 3000 meters (60 deg – means 30 deg using German angle methodology, at that point Czechoslovak army was using the German trial methods, unlike the pre-war ones, that were very obscure).
