The Cannone da 75/27 A.V. was an anti-aircraft gun developed in Italy during the First World War that also saw service during the Second World War.

History

The 75/27 A.V. (Anti Velivolo, Anti-Aircraft) cannon was privately developed by Ansaldo to supply an anti-aircraft gun to the Regia Esercito.

Technical

The 75/27 A.V. used the barrel and hydro-spring recoil mechanism from the Cannone da 75/27 modello 06 a license-built version of the Krupp Kanone M 1906 field gun to speed up production and it used the same Fixed QF 75 x 185mm R ammunition. The barrel consisted of a rifled liner with 28 left-handed grooves, and an external jacket, it was 2.025 m (6 ft 8 in) L/27 long and weighed 346 kg (763 lb) including the semi-automatic horizontal sliding-wedge breech. The breech closed automatically when a projectile was fed into the chamber and after firing the shell casing was ejected and the breech was held open for the next round.[2]

Variants

  • The 75/27 A.V. - was mounted on a static center pivot mount with -5° to + 80° of elevation and 360° of traverse. The 75/27 A.V. was used during the First World War for the defense of metropolitan areas by the Regia Esercito. During the Second World War it was assigned to coastal defense, anti-aircraft, and second line units.[3]
  • The Autocannone da 75/27 C.K. - was a self-propelled anti-aircraft gun with a new pedestal mount and new recoil mechanism that was mounted on the chassis of a Lancia 1Z truck. In 1915 these formed the basis of Italy's first truck-mounted artillery. Eventually, twenty-seven batteries of five guns were formed during World War I.[4]
