'''DARDO''' ("Dart" in Italian), also marketed as the '''OTO Twin 40L70 Compact''',<ref name=":0">{{Cite web |title=OTO TWIN 40L70 COMPACT NAVAL MOUNT |url=https://electronics.leonardo.com/documents/16277707/18299996/OTO+Twin+40L70+%28mm08756%29_LQ.pdf |access-date=2023-12-10 |website=Leonardo Electronics |publisher=Leonardo S.p.A.}}</ref> is a [[Engineering:Close-in weapon system|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) [[Engineering:Shell (projectile)|shells]], a fire-control radar (RTN-10X) and a [[Engineering:Fire-control system|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&nbsp;mm [[Engineering:Autocannon|autocannon]]s (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 [[Engineering:Anti-ship missile|anti-ship missile]]s, [[Engineering:Unmanned aerial vehicle|unmanned aerial vehicle]]s and other precision guided weapons. It can also be employed against conventional and rotary-wing aircraft, surface ships, small water-crafts, [[Earth:Coast|coast]]al targets and floating mines.

==Installation==
DARDO is installed in an enclosed [[Engineering:Gun turret|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). However, the most recent OTO Twin 40L70 Compact's brochure nominates 736-round magazine for Type A and 444-round magazine for Type B, both feature deck penetration.<ref name=":0" />

The newest Marlin 40 variant has no deck penetration, having a sole internal magazine for 80 ready-to-fire rounds.<ref name=":1">{{Cite web |title=OTO Marlin 40 |url=https://electronics.leonardo.com/en/products/oto-marlin-40 |access-date=2023-12-10 |website=Leonardo Electronics |publisher=Leonardo S.p.A. |language=en-US}}</ref>

==Other versions==

=== Compact ===
The '''OTO Twin 40L70 Compact''' is the current [[Finance:Marketing|marketing name]] for the DARDO. Option for a [[Engineering:Stealth technology|stealth]] cupola is available to reduce the gun mount's [[Physics:Radar cross section|RCS]].<ref name=":0" />

=== Fast Forty ===
The '''Single 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 [[Physics:Kinetic energy penetrator|armour-piercing fin-stabilized discarding sabot]] (APFSDS) rounds when a missile gets within 1,000 meters from the vessel. However, unlike the original DARDO/OTO Twin Compact, it is only featured with a single barrel.<ref>{{Cite web |date=2013-05-20 |title=Oto Melara introduced a new version of its FAST FORTY naval mount during IDEF 2013 |url=https://navyrecognition.com/index.php/naval-news/naval-news-archive/year-2013-news/may-2013-navy-world-naval-forces-maritime-industry-technology-news/1053-oto-melara-introduced-a-new-version-of-its-fast-forty-naval-mount-during-idef-2013.html |access-date=2023-12-10 |website=Navy Recognition |language=en-gb}}</ref>

=== Marlin ===
The '''OTO Marlin 40''' is the single-barrel, light-weight and no-deck-penetration derivative of the DARDO family, succeeding the Single Fast Forty variant. It is designed with high autonomy and fully-digitalized systems.<ref name=":1" />
