DARDO ("Dart" in Italian) originally known as Breda Type-70, also marketed as the OTO Twin 40L70 Compact, is a close-in weapon system (CIWS) built by the Italian companies Breda and Oto Melara. It is composed of two Breda-built Bofors 40 mm firing high explosive (HE) shells, a fire-control radar (Alenia RTN-10X Orion) and a fire-control system (Alenia RTN-20X Orion and Dardo). It is the last of a long series of Italian anti-aircraft weapons derived from the Swedish Bofors 40 mm autocannons (mounted on Breda built gun mounts such as the Type 64, Type 106, Type 107, Type 564 and Type 520).
