The Cannone da 90/53
was an Italian
anti-aircraft gun used during World War II
, both in the anti-aircraft role and an anti tank gun. (The designation meant that the gun had a 90 mm caliber and that the barrel was 53 caliber-lengths long).
The Cannone da 90/53 was designed by Ansaldo and the first examples were produced in 1939.
The original plan was for the gun to be manufactured in three variants:
- the modello 41P was for static emplacement; 1087 were ordered
- the modello 41C was to be towed; 660 were ordered
- 57 were ordered to be mounted on heavy trucks designated autocannoni da 90/53
However Italian industry was not up to producing these quantities and by July 1943 only 539 guns had been delivered.
After Italy surrendered, guns captured by Germany were designated 9-cm Flak 41(i) or 9-cm Flak 309/1(i); some of these guns were used for the air defence of Germany and others were kept in Italy.
