Autocannone 75-27 AV (Anti-Velivolo) su autocarro semiblindato LANCIA 1Z (1918)

History

Let’s go back a long way in the history of war vehicles. In 1917 the Royal Army needed artillery to defend the metropolitan areas and the border from possible Austro-Hungarian air attacks. It was therefore decided to start working on a cannon truck, and the 75/27 AV was chosen as the cannon and the Lancia 1Z as the truck. In a short time, 6 anti-aircraft batteries were armed with the necessary vehicles for transporting ammunition and the vehicles were assigned to the 61st experimental artillery regiment. The vehicle was vaguely unsuitable as an anti-aircraft due to its very small size compared to the mounted weapon, on the other hand the vehicle proved to be good as an infantry support vehicle and as self-propelled artillery. What happened to the vehicles at the end of the conflict is unknown.

Armament and propulsion

The truck was armed with an Ansaldo 75/27 A.V. cannon. with 360° traverse and -5°/+80° elevation. The gun mounted on the truck, the 75/27 A.V., being derived from the 75/27 C.K. gun. it had the exact same characteristics and ammunition. It could fire two types of anti-aircraft ammunition, one explosive (with temporized fuze) and one incendiary shrapnel. The cannon also had a semi-automatic breech which allowed the weapon to be reloaded in 3 seconds.
Moving on to the engine, the truck had a Lancia Tipo 61 engine 4,490 cc I4 petrol which allowed the vehicle to reach a maximum speed of 60 km/h.
