The 76mm/L62 Allargato is a single barrel, medium caliber, dual purpose automatic naval cannon designed and produced in the 1960s by the Italian defence firm of OTO-Melara as the cannon armament for all medium and large warships built for the Italian Navy in that decade. Currently, the gun remains in service with Italy's Cassiopea-class patrol vessels but has otherwise been largely replaced by the Otobreda 76 mm series of cannons.
