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 class 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.
