Fiat L6/40 Light Tank Details and Specifications

Background on the Fiat L6/40

The Fiat L6/40 developed as a replacement to the Carro Veloce CV 33 tankette and intended for the export market. The export demand didn’t materialize, but the Regio Esercito showed an interest in this light tank. In 1936, Fiat-Ansaldo completed the first prototypes. One came armed with coaxial 8mm MG and another armed with a 37 mm cannon. The armament was standardized to a Breda Modello 35 20 mm main gun and an 8 mm Breda 38 coaxial machine gun. The Italian Army ordered 283 L6/40’s which Fiat-Ansaldo delivered between 1941 and 1942. The tank faired well against other light tanks but became quickly outclassed by Allied medium tanks on the battlefield.

The hull was of riveted construction with a minimum thickness of 6mm of armor and a maximum thickness of 30mm. The driver sat at the front of the hull on the right; the turret is offset to the left, and the engine is in the rear. The suspension consists of two bogies each with two road wheels, with the drive sprocket at the front and the idler at the rear.

The Breda Mod 35 20 mm gun has an elevation of +20 degrees and a depression of -12 degrees. The L6/40 carries 296 20 mm rounds and 1,560 rounds of 8 mm rounds.

The L6/40 saw service in North Africa, the Eastern Front, Balkans, and Italy.
