General Information
The LT-34 (CKD/Praga P-II) based on the existing Light Tank and was in use from 1934.

It was armed with 2 light machine guns. Its main armament consisted of an Skoda 37mm P.U.V. vz34 L/39 which could penetrate 42 mm of flat plate at 200 metres

The LT-34 was the first tank built in Czechoslovakia in volume with 50 machines ordered by the government. In 1938 they were upgraded with the LT-38 engine.

When the Germans invaded the tanks were given to Romania.

The Praga 62hp petrol engine drove the tracks from the front sprocket under eight road wheels on two bogies to the rear idler then back over four return rollers.

The turret similar in design to the LT-35 housed the 37mm gun.

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.

The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive and numerous books and websites that have provided the detailed information that has not been available anywhere else. The information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre, the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
