Surface Combatant Weapon System Oto-Melara / Otobreda 40L70 DARDO twin 40mm close-in weapon system (“compact” or “fast-forty”)
The Oto-Melara/Otobreda twin 40L70 compact / fast forty gun system is a high performance anti-missile, anti-aircraft and ship-to-ship weapon system. 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). The mount can be upgraded with the installation of the “fast-forty” recoiling mass. 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 hight-explosive (HE) to armour-piercing fin-stabilized discarding sabot (APFSDS) rounds when a missile gets within 1,000 meters from the vessel.
