GIAT 30 is a series of French 30 mm autocannons developed for naval and aircraft applications. Designed in the late 20th century, the family includes gas-operated and revolver-cannon concepts adapted for shipboard, rotary-wing, and fixed-wing use. The systems entered service with French armed forces and were exported to allied operators, integrating with combat aircraft such as the Dassault Rafale and naval platforms including the Horizon-class frigate.
The weapon lineage originated from requirements set by the French Navy, Direction générale de l'armement, and Nexter Systems to replace older 20 mm and 30 mm systems used on platforms like the Super Étendard and SEPECAT Jaguar. Initial design work involved engineers from the Atelier de Construction de Tarbes and technical staff formerly of GIAT Industries collaborating with avionics teams from Thales Group and propulsion specialists tied to SNECMA. Tests were conducted at ranges near Istres-Le Tubé Air Base and at naval proving grounds off Brest, with trials overseen by procurement officials from the Ministry of Armed Forces (France) and advisers from the NATO procurement office. The result was a compact, lightweight cannon family—variants tailored to Dassault Aviation fighters, NHIndustries helicopters, and DCNS-built warships.
The design employs a 30 mm bore firing NATO-standard 30×113mm or similar ammunition types used by platforms such as the AH-64 Apache and A-10 Thunderbolt II. Feed mechanisms vary between linkless and linked belts compatible with storage systems used on the Dassault-Breguet Super Étendard Modernisé and Eurocopter Tiger. Rate of fire options span roughly 750 to 1,500 rounds per minute, comparable to systems mounted on the F-16 Fighting Falcon and Eurofighter Typhoon. Muzzle velocity for armor-piercing rounds approaches 1,080 m/s, enabling engagement envelopes similar to the Mauser BK-27 and the M61 Vulcan in certain employment scenarios. Electro-mechanical firing controls integrate with fire-control suites developed by Thales, allowing targeting data input from radars like the RBE2 and optronics from vendors including SAGEM.
Variants were developed to meet diverse platform needs: a podded version for export platforms akin to pods used by General Dynamics systems; a helicopter-turret variant comparable to guns on the AH-1 Cobra; and a naval mounting compatible with close-in weapon systems aboard La Fayette-class frigate and Forbin (D620). Industrial names correspond to configurations supplied to Dassault Aviation for the Rafale internal gun bay, to NHIndustries for the Tiger turret, and to Naval Group installations for littoral combatants. Export batches were tailored for customers such as Greece, Spain, and India, matching local integration standards from firms like Airbus Defence and Space and Hindustan Aeronautics Limited.
Deployment began in the 1980s and expanded through the 1990s with introduction on carrier-borne aircraft deployed from FS Charles de Gaulle and during maritime patrols in the Mediterranean Sea and Persian Gulf. The cannon family saw operational use in conflicts where French forces and coalition partners engaged in Operation Enduring Freedom, Operation Harmattan, and peacekeeping or maritime security operations near Somalia and Libya. Nations operating the weapon integrated it into mission sets ranging from air interdiction to ship self-defense during patrols alongside United States Navy and Royal Navy units under multinational task groups.
Primary operators included the French Navy, French Air and Space Force, and export customers such as the Hellenic Navy, Spanish Navy, and several air arms procuring the Dassault Rafale or compatible helicopter platforms. Industrial partners and licensed producers included Nexter, Thales Group, and maintenance agreements involved entities like Dassault Aviation maintenance depots and national arsenals such as the Direction Générale de l'Armement support facilities.
In combat, the system provided high-rate direct-fire capability effective against light armored vehicles, small craft, and aerial targets including helicopters and unmanned systems encountered during Operation Inherent Resolve-era conflicts. Integration with helmet-mounted sights and electro-optical sensors from SAGEM and fire-control radars from Thales allowed pilots and ship crews to employ the cannon in both air-to-ground and close-in surface engagements, with engagement doctrines resembling those used by units operating the M61 Vulcan or Gryphon Systems-equipped aircraft. Damage assessments in engagements over littoral environments indicated effective neutralization of fast attack craft and insurgent ground positions when coordinated with precision-guided munitions provided by platforms like the Rafale.
Sustainment programs were managed through contracts with Nexter Systems and overhaul centers affiliated with Direction Générale de l'Armement, encompassing barrel replacement schedules, feed system refurbishment, and electronic upgrades to fire-control interfaces. Mid-life upgrades incorporated improved materials from suppliers such as Safran and refinements to ammunition handling inspired by experiences with systems like the Mauser BK-27. Software updates ensured continued compatibility with avionics suites from Thales and mission computers from Dassault Systèmes-derived architectures, extending service life into the 21st century.
