Pre–World War I

It was founded in 1905 as a joint venture of Vickers and Terni Steelworks, Cantiere navale fratelli Orlando and Cantieri navali Odero. Investment was also provided by Giuseppe Orlando and Attilio Odero. During World War I, Vickers Terni produced many weapons with calibre 40 mm and upwards. In 1929 the company was renamed Odero Terni Orlando with the abbreviation OTO. During World War II, mostly heavy guns for battleships were produced.

Post–World War II

In 1953 the company took the name OTO Melara.

Before Italy joined NATO, OTO Melara produced civil products, like tractors and looms, but quickly returned to the production of weapons. On 1 December 2001, the naval artillery division of OTO Melara merged with that of Breda Meccanica Bresciana to form Otobreda. The combined entity produces the DARDO CIWS, Otobreda 76 mm and Otobreda 127/54 Compact naval guns. OTO Melara's land defence operations are part of the Finmeccanica conglomerate.

76mm/L62 Allargato

The 76mm/L62 Allargato is a single barrel, medium caliber, dual purpose automatic naval cannon designed and produced in the 1960s by the Italian defence firm of OTO-Melara as the cannon armament for all medium and large class warships built for the Italian Navy in that decade. Currently, the gun remains in service with Italy's Cassiopea class patrol vessels but has otherwise been largely replaced by the Otobreda 76 mm series of cannons.

ARM Oaxaca

ARM Oaxaca (PO-161) is the lead ship of the Oaxaca class of patrol vessels, constructed by and for the Mexican Navy.

It has a length of 282.2 feet (86.0 m), a draft of 11.8 feet (3.6 m), a beam of 34.4 feet (10.5 m), and displaces 1,850 short tons (1,678.3 t).Primary armament is a single OTO Melara 76 mm naval gun, with a pair of OTO Melara 12.7 mm remote controlled naval turret Mod. 517 with M2 12.7mm machine guns on each side, and an Oto Melara single 30/SAFS 30 mm cannon aft.

A helipad on the afterdeck has handling capabilities for a variety of helicopters, such as the Panther, Fennec, or the Bolkow Bo 105 Super-5.

The ship has a cruising speed of 20 knots (37 km/h), carries a complement of 77, and has provisions to carry a group of 39 special forces and/or marines for a variety of missions.

Acciaio-class submarine

The Italian Acciaio-class submarine (also sometimes called Platino class) was the fifth subclass of the 600 Series of coastal submarines built by the Regia Marina. They were completed during the early 1940s and saw service in World War II.


The C1 Ariete is the main battle tank of the Italian Army, developed by Consorzio Iveco Oto Melara (CIO), a consortium formed by Iveco and Oto Melara. The chassis and engine were produced by Iveco, while the turret and fire-control system were supplied by Oto Melara. The vehicle carries the latest optical and digital-imaging and fire-control systems, enabling it to fight day and night and to fire on the move. Six prototypes were developed by 1988, which were subject to intensive testing the following year during which the vehicles travelled a combined 16,000 km. Deliveries were first planned for 1993, but in fact took place in 1995 due to delays. Final delivery occurred 8 years later in August 2002.

B1 Centauro

The Centauro is a family of Italian military vehicles originating from a wheeled tank destroyer for light to medium territorial defense and tactical reconnaissance. It was developed by a consortium of manufacturers, the Società Consortile Iveco Fiat - Oto Melara (CIO). Iveco Fiat was tasked with developing the hull and propulsion systems while Oto Melara was responsible for developing the turrets and weapon systems.

Over the years, the Centauro platform has been developed into multiple variants to fulfill other combat roles, such as infantry fighting vehicle or self-propelled howitzer.

Calvi-class submarine

The Calvi class was a class of three submarines built by Oderno-Terni-Orlando in Genoa for the Royal Italian Navy (Italian: Regia Marina). The submarines were built in 1935, and all three served in the Mediterranean at the start of the Second World War. The boats were transferred to the BETASOM Atlantic submarine base at Bordeaux in August 1940. In December 1941 the boats were used for a rescue mission of 254 sailors from the sunken German auxiliary cruiser Atlantis. After Calvi had been sunk, Finzi and Tazzoli were selected for conversion to "transport submarines" in order to exchange rare or irreplaceable trade goods with Japan. Cargo capacity of 160 tons reduced reserve buoyancy from 20–25% to 3.5–6%; and armament was reduced to defensive machine guns.

Cantieri navali Odero

Cantieri navali Odero (Shipyard Odero) is a defunct Italian shipyard. Founded in 1846 by the Westerman brothers in Genoa-Sestri Ponente, the company was taken over by Nicolò Odero in 1872. Together with the Ansaldo-San Giorgio shipyard at Muggiano and the armament works of Vickers-Terni it was amalgamated into Odero-Terni by Attilio Odero, which, in turn, absorbed the Cantiere navale fratelli Orlando of Livorno two years later. The consolidated company became the Società per la Costruzione di Navi, Macchine ed Artiglierie Odero-Terni-Orlando (OTO) (later OTO Melara). The shipyard was closed in 1949.

Dardo IFV

The Dardo is an infantry fighting vehicle designed for the Italian Army as a replacement for the M113 APC. It is designed and built by the Iveco Fiat Oto Melara Syndicated Company based in Rome. Iveco is responsible for the hull and propulsion systems, while Oto Melara is responsible for the weapons and fire control systems.

Fiat 6614

The Fiat Type 6614 is a 4x4 wheeled armoured personnel carrier developed as a joint venture between Fiat and Oto Melara of Italy. The hull is welded steel, and the vehicle is amphibious. The first prototype was built in 1972.

Italian submarine Acciaio

The Italian submarine Acciaio was the name ship of her class of submarines built for the Royal Italian Navy (Regia Marina) during World War II.


The OF-40 is an Italian main battle tank developed as a joint venture between OTO Melara and Fiat, and intended primarily for export sales. OTO Melara would develop and produce the hulls, and automotive components would be provided by Fiat (the designation of the vehicle comes from the initials of the two companies, whereas "40" refers to the planned mass of the tank). Initial design work was started by OTO Melara in 1977, with the first prototypes ready by 1980.

OTO Melara 76 mm

The OTO Melara 76 mm gun is a naval gun built and designed by the Italian defence company Oto Melara. It is based on the Oto Melara 76/62C and evolved toward 76/62 SR and 76/62 Strales.

The system is compact enough to be installed on relatively small warships. Its high rate of fire and availability of range of ammunition make it capable for short-range anti-missile point defence, anti-aircraft, anti-surface, and ground support. Ammunition includes armour-piercing, incendiary, directed fragmentation effects, and a guided round marketed as capable of destroying manoeuvring anti-ship missiles. A stealth cupola is now offered.

The OTO Melara 76 mm has been widely exported and is in use by sixty navies. It has recently been favoured over the French 100mm naval gun for the joint French/Italian Horizon-class frigate project and FREMM frigate.

On 27 September 2006 Iran announced it has started mass production of a marine artillery gun, named the Fajr-27, which is a reverse-engineered Oto Melara 76 mm gun.

OTO Melara Mod 56

The OTO-Melara Mod 56 is an Italian-made 105 mm pack howitzer built and developed by OTO-Melara. It fires the standard US type M1 ammunition.

Obice da 149/12

The Obice da 149/12 was an Italian howitzer produced under license in Italy by Ansaldo and Vickers-Terni which was used during World War I and World War II.

Obice da 149/19 modello 37

The Obice da 149/19 modello 37 was a heavy howitzer which served with Italy during World War II. It was intended to replace Italy's assortment of World War I-era heavy howitzers, but this was prevented by the prolonged development time and the very slow pace of production. Despite orders totaling 1392 weapons only 147 had been built by September 1942. There were three models, the 37, 41 and 42, differing only in details. The standard tractor was the Trattore SPA TM 40. While an unremarkable design the Germans liked it enough to keep it in production with the designation of 15 cm sFH 404(i) after the Italian surrender in 1943. With the same weight it had superior range compared to the German 15 cm sFH 18. It was used by the Italian army until 1974.

Otobreda 127/54 Compact

The Otobreda 127mm/54 Compact (127/54C) gun is a dual purpose naval artillery piece built by the Italian company Oto Melara. It uses the 127mm round which is also used in the 5 inch/ 54 gun, albeit that this gun calibre is measured in United States customary units rather than metric. The gun uses an automatic loading system where 66 127mm rounds of various kinds can be stored ready-to-fire in three loader drums (each holding 22 rounds). The barrel is water-cooled. Currently the gun is still in use by navies around the world but it is slowly being replaced by the Otobreda 127/64 for new vessels, such as the German Navy's F125-class frigate and Italian Navy's FREMM.

Otobreda 127/64

The Oto Melara 127/64 Lightweight (LW) naval gun mount is a rapid fire gun mount suitable for installation on large and medium size ships, intended for surface fire and naval gunfire support as main role and anti-aircraft fire as secondary role. The compactness of the gun feeding system makes possible the installation on narrow section crafts.

The gun can fire all standard 127 mm (5 inch) ammunition including the new Vulcano long range guided ammunition.

Modular automatic feeding magazines allow the firing of up to four different and immediately selectable types of ammunition; the magazines (four drums, each with one shell ready to fire and 13 other ammunitions on store) can be reloaded while the mount is in operation.

An ammunition manipulator system is available to transport projectiles and propelling charges from the main ammunition store to the feeding magazines, which are automatically reloaded. Ammunition flow is reversible. Rounds can be automatically unloaded from the gun. Digital and analog interfaces are available for any Combat Management System, also according to COBRA protocol.

The 127/64 LW naval gun mounts includes a Vulcano module, which acts twofold:

Programmer for ammunition's fuse and guidance system

Mission Planning and Execution for Naval Fire Support Action (firing solutions, selection of ammunition, definition of trajectories and firing sequences, ballistic computations accounting for ammunition type, etc.), as a standalone or in interaction with ship's Network Centric System


The Otomat is a short-range subsonic anti-ship and coastal defence missile developed by the Italian company Oto Melara jointly with Matra and now made by MBDA. The name comes, for the first versions, from the name of the two builders (OTO Melara MATra) and, for the later versions, Teseo, from the Italian word for Theseus. The MILAS variant is an anti-submarine missile.

In its latest version Mk/2E purchased by the Italian Navy is a medium range anti-ship missile and a ground attack missile.

Puma (AFV)

The Puma is a family of Italian light wheeled armoured fighting vehicle family, consisting of the Puma 6×6 and the Puma 4×4. The vehicles were developed and are produced by the Consorzio Iveco Fiat – Oto Melara for the Italian Army. First prototypes completed in 1988, with a total of five testbed vehicles being completed by 1990.

The 4x4 variant carries 3 troop members plus the driver, the 6×6 variant carries 6 troops plus driver.
