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&nbsp;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). 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 non-deck penetration or with 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>

Option for a stealth cupola is available to reduce the gun mount's RCS.<ref name=":0" /> They come in Type A version with 736 round magazine & Type B version with 444 round magazine. Both the Type A and Type B mounting can be installed above-deck (non-penetrating) or with below-deck magazine. The compact mounting has maximum fire rate of 600 round/min (300 round/min × 2). A kit to upgrade Compact mounting to Fast Forty standard is available.<ref name=":2" /> thumb|300x300px|Single Fast Forty mounting on Kuwaiti navy ''Um Al Maradim''-class missile boat, ''Al Fahaheel'' (P3721). === Fast Forty === The '''Fast Forty''' is an improved version of the Compact mounting with a higher fire rate of 900 round/min (450 round/min × 2), dual magazine and dual feed mechanism to allow switching from High Explosive (HE) rounds to Armour-Piercing Fin-Stabilized Discarding Sabot (APFSDS) rounds when a target gets within 1,000 meters from the vessel. Produced in both Single-barrel ('''Single Fast Forty''') and Twin-barrel ('''Twin Fast Forty''') forms, the Fast Forty include a revision of some parts of the loading and breech mechanism and the use of titanium material to improve the performance compared to the Compact mounting. Ammunition magazine and feed arrangements of the Twin Fast Forty remain the same as the Compact but operate at a higher speed. The gun laying and acceleration rates were increased, while the barrel/barrels, are secured in a barrel guidance frames to improves accuracy.<ref name=":2" />

The '''Single Fast Forty''' has on-mounting ammunition capacity of only 144 round and are available in three types of mounting:

* Type A: unmanned mounting, with all operation are done via remote control, * Type B: manned mounting, controlled and aimed by an on-turret operator, * Type C: unmanned mounting, feature an integral Micro Fire Control System (MFCS) with automatic tracking and fire-control computation.<ref name=":2" />

An optional 'Stealth' cupola that provided a significant reduction in the radar cross-section of the mounting are also available.<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 |archive-url=https://web.archive.org/web/20211019095643/http://www.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 |url-status=dead |archive-date=October 19, 2021 |access-date=2023-12-10 |website=Navy Recognition |language=en-gb}}</ref>

The system comes in a basic version called "'''Remotely Controlled'''" ('''RC'''), which can be managed by an external firing control system and in the advanced version called "'''Independent Line Of Sight'''" ('''ILOS'''), which can be operated autonomously via a local control console in addition to be fully controlled by Combat Management System. It also has selectable rate of fire ranging from single shot, 100 round/min and 300 round/min.
