DARDO

DARDO ("Dart" in Italian) 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 (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 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).

Purpose

The system's primary purpose is to defend against anti-ship missiles, unmanned aerial vehicles and other precision guided weapons. It can also be employed against conventional and rotary-wing aircraft, surface ships, small water-crafts, coastal targets and floating mines.

Installation

DARDO 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 (Type B requires no deck penetration).

Other versions

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.
