General Information

The LT-34 (CKD/Praga P-II), it was based on the Light Tank chassis and was in use from 1934. It was commonly called a CKD/Praga P-II.

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 46.2 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.

About Penetration Figures

All penetration figures in this database are calculated to a common standard based on German WWII testing criteria (complete penetration with functioning fuze). This allows direct comparison between all nations' guns.

Original national test figures would be higher for some nations due to different criteria:

German: 1.00? (baseline - strictest)
British: 1.02? (slightly looser)
American: 1.05? (50% mass through plate)
Soviet: 1.10? (75% mass through plate)

For example, a Soviet gun showing 159mm here would be published as ~175mm in Soviet documents, and a German gun showing 120mm would be published as 120mm in German documents. The 159mm figure is directly comparable to the German 120mm - the Soviet gun really was more powerful.

National Testing Standards
German:	1.00? - Complete penetration, fuze functions (strictest)
British:	1.02? - Complete penetration
American:	1.05? - 50% of shell mass through plate
Soviet:	1.10? - 75% of shell mass through plate
All database figures are normalized to German standard for direct comparison. Multiply by the factor above to see original national test figures.

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.
