DARDO, built by the Italian companies Breda and Oto Melara, is a Close-in weapon system (CIWS) composed of two Breda 40 mm L/70s firing high explosive (HE) shells, a fire-control radar (RTN-10X) and a fire-control system (RTN-20X and Dardo). It is the last of a long series of Italian anti-aircraft weapons derived from the Bofors 40 mm gun (Type 64, Type 106, Type 107, Type 564 and Type 520).
The system's primary purpose is defence against anti-ship missiles, unmanned aerial vehicles and other precision guided weapons. However it can also be employed against fixed- and rotary-wing aircraft, ships and other small craft, coastal targets, and floating mines. It is installed in an enclosed turret with two different mounts: the Type A with 440-round internal and 292-round under-deck magazines; and Type B with only the 440-round internal magazine (the Type B mount is fitted without deck penetration).
The Fast Forty is an improved version of the system with a higher rate of fire, dual magazine and dual feed mechanism to allow switching from HE to armour-piercing fin-stabilized discarding sabot (APFSDS) rounds when a missile gets within 1,000 meters from the vessel.
