Overview

Avio S.p.A. is an Italian aerospace enterprise headquartered in Colleferro, near Rome, Italy. Established in 2003 through a merger and with origins dating back to 1908, the company maintains a presence both domestically and internationally, operating multiple commercial offices alongside 10 manufacturing facilities. Avio specializes in:

• solid-propellant propulsion systems for space applications and tactical uses
• electronic and electrical control and automation technologies

As the Prime Contractor for the European launch vehicle Vega and a subcontractor for the Ariane program—both funded by the European Space Agency (ESA)—Avio plays a significant role in Europe's space initiatives.

The company is heavily engaged in technological innovation, collaborating with 14 Italian and 10 international universities and research institutions to advance product development and manufacturing processes. Avio also focuses on researching environmentally sustainable solutions aimed at minimizing the ecological footprint of aircraft engines, aligning with consumption and emission reduction targets set by the ACARE organization within Europe.

With operations spanning five locations across Italy, France, and French Guiana, Avio employs approximately 1,200 staff members, about 30% of whom are dedicated to research and development activities.

Avio is publicly traded on the Milan Stock Exchange within the Star segment. In 2018, the company reported revenues amounting to €388.7 million.

Early 20th century

Around 1908, Turin, Italy, was witnessing the initial phases of aeronautical manufacturing. During this period, Fiat embarked on designing and producing an aircraft engine named the SA 8/75, which was adapted from racing car technology. Fiat's first engine to be produced on a large scale was the A10 model, with a total of 1,070 units manufactured between 1914 and 1915. This period marked the end of the pioneering phase, prompting the company to shift focus toward designing and building complete aircraft. Consequently, in 1916, Società Italiana Aviazione was established, later rebranding as Fiat Aviazione in 1918.

In addition to aircraft engines, Fiat expanded its production in Turin by venturing into marine diesel engines with the creation of Fiat San Giorgio in 1909. This sector eventually evolved into activities related to industrial engines used for electricity generation. Meanwhile, in Colleferro near Rome, the Bombrini Parodi-Delfino (BPD) Company—originating from Genoa in 1912—began producing explosives and chemical products, laying the groundwork for future aerospace developments.

Aeronautical operations also took root in Brindisi through the SACA Company. Over time, several other enterprises emerged, including CMASA di Marina in Pisa, founded in 1921 by German engineer Claude Dornier in partnership with Rinaldo Piaggio and Attilio Odero.

Development of large engines and turbines

Avio played a role in advancing and manufacturing engines designed for electric power generation and had experience building large engines for maritime vessels.

Fiat’s involvement with marine engines dates back to 1903. Starting in 1926 under engineer Giovanni Chiesa’s leadership, production commenced on engines featuring cylinders with a diameter of 750mm—the technological limit at that time—boosting power output up to 4,500 horsepower. In 1971, a new facility opened in Trieste for producing large diesel engines through a partnership with IRI (Institute for Industrial Reconstruction), a state-owned entity.

From the 1930s onward, diversification strategies led Avio to enter the railway diesel engine market, branching out from its expertise in ship and submarine propulsion systems. In the early post-war years, initial experiments were conducted on diesel engines tailored for industrial electric power generation. A significant milestone occurred in 1954 when Avio began developing gas turbines via a collaboration agreement with Westinghouse. This expertise, combined with increased methane gas availability, enabled Avio to design and build multiple power plants both domestically and internationally.

The success achieved with gas turbines prompted a strategic exit from large diesel engine production to concentrate exclusively on turbine technology. In 1973, Fiat established Turbomeccanica Turbogas (TTG), dedicating itself fully to energy sector activities based in Turin. TTG was absorbed by Fiat Aviazione in 1986 and continued operations until 2001 when it was transferred to Siemens; thereafter, marine and industrial divisions shifted focus toward aeroderivative turbine development.

Advancement in Explosives and Propellant Technologies

The BPD manufacturing facilities were established approximately 50 km from Rome, along the rail route to Cassino, driven by engineer Leopoldo Parodi – Delfino’s vision, with backing from Senator Giovanni Bombrini and the State’s decision to ensure Italy possessed autonomous chemical production capabilities.

Located in an economically disadvantaged area of the Roman countryside, the settlement of Colleferro emerged around this industrial complex and was officially recognized as a municipality in 1935 through a Royal Decree. The town’s expansion was closely linked to BPD’s operations, which initially focused on explosives before diversifying into various chemical products for agricultural and industrial applications. As the manufacturing sites grew, they attracted a workforce, and the company invested in social infrastructure for the community.

In 1927, the BPD Test Centre commenced trials on early rockets powered by chemical propellants. Post-World War II, under the leadership of Francesco Serra di Cassano—successor and son-in-law of BPD’s founder—mechanical production initiated in the 1930s for munitions was further developed and scaled. The Test Centre intensified its work on propellants, notably launching multi-stage sounding rockets designed for upper atmosphere research at the Salto di Quirra military firing range in Sardinia during the early 1960s.

Following its achievements in rocketry, BPD secured a contract in 1966 with ELDO (the precursor to the European Space Agency – ESA) to develop and produce the apogee boost motor for the ELDO-PAS telecommunications satellite. This collaboration marked BPD’s entry into solid-propellant motor development.

By 1968, SNIA Viscosa acquired BPD, which was renamed SNIA-BPD. Within this structure, ESA entrusted SNIA-BPD in 1975 with developing and manufacturing separation motors for the European Ariane launch vehicles. Later, in 1984, SNIA-BPD received contracts for producing boosters for the Ariane 5. Production of Ariane launch motors has continued for over two decades at the French Guiana launch site through subsidiaries Europropulsion and Regulus, both established in 1988.

In 1990, SNIA divested its BPD division to Gilardini Company, which was subsequently acquired by Fiat Aviazione in 1994. From 1989 onward, Fiat Aviazione operated under the name FiatAvio S.p.A.

Aviation Sector Developments

Main articles: Fiat Aviazione and Aeritalia

Fiat assumed responsibility as Italy’s primary contractor for NATO’s F-104G fighter aircraft. Following its rebranding to Fiat Avio in 1989, the company engaged in designing and producing propulsion systems for military platforms such as the Panavia Tornado and Harrier, as well as commercial aircraft from Boeing and Airbus.

A significant milestone occurred in 1997 when Fiat Avio acquired a controlling interest in Alfa Romeo Avio from Finmeccanica. This strategic move aimed to consolidate Italy’s aerospace industry by reducing fragmentation among companies and enhancing competitiveness through coordinated synergies.

2000 to 2011

During this period, Avio embarked on a path of expanding its global presence, establishing itself as a leading international entity in the design and manufacture of aerospace propulsion components and modules. The company's international growth included the establishment of AvioPolska in 2001, followed by the acquisition of Phillips Aerospace in 2005, which led to the creation of DutchAero.

In 2003, amid challenges in the automotive industry, Fiat Group divested Fiat Avio S.p.A., selling it to a consortium composed of The Carlyle Group (holding 70%) and Finmeccanica S.p.A. (owning 30%), outbidding French rival Snecma. At that time, Fiat Avio was valued at approximately €1.5 billion and subsequently rebranded as Avio S.p.A.

By August 2006, the British investment firm Cinven announced its acquisition of Avio S.p.A. from Carlyle for €2.57 billion. Following this transaction, Avio S.p.A. became wholly owned by BCV Investments S.C.A., a Luxembourg-based entity primarily controlled by Cinven Limited (85%) and Leonardo S.p.A. (15%).

The 2012 Spin-Off

In December 2012, an agreement was reached for General Electric to acquire Avio Spa’s aeronautical division. This transaction was completed on 1 August 2013 at a price of €3.3 billion, resulting in the separation of Avio’s space segment—which remained under the ownership of Cinven and Leonardo—and its aviation segment, which was renamed Avio Aero and integrated into GE Aviation as an independent entity no longer affiliated with the Avio Group.

From 2012 to Present

Vega Launcher

Avio’s principal project currently is the European Vega light-lift launch vehicle. This rocket features four stages: the initial three utilize solid propellant motors, while the final stage employs liquid propulsion technology. The vehicle stands approximately 30 metres tall with a maximum diameter of 3 metres and can deliver payloads up to 1,500 kg into a polar orbit at an altitude near 700 km.

The Vega rocket achieved its inaugural flight in February 2012. Following this successful debut, its significance has increased substantially, completing eighteen missions that have deployed various payloads into orbit, including numerous microsatellites for private enterprises, institutional bodies, and governmental agencies. Notably, during the VV04 mission, Vega launched the IXV (Intermediate eXperimental Vehicle), a prototype for Europe’s reusable Space Rider, on a sub-orbital trajectory.

Within the Vega programme framework, Avio serves as the prime contractor responsible for developing next-generation light launchers:

• Vega C, with its qualification flight planned for 2022;
• Vega E, for which initial studies commenced and prototype testing of the M10 liquid oxygen-methane engine began on a reduced scale in 2018; full-scale prototype tests were successfully conducted in 2020. The qualification flight is targeted for 2025.

Ariane 5 and Ariane 6 Launch Vehicles

The Ariane initiative emerged in the early 1970s with the goal of creating launch vehicles optimized for geostationary transfer orbits, supported by the European Space Agency (ESA) and led by Ariane Group as the main contractor.

Since the 1970s, Avio has contributed to the design and manufacturing of boosters and stage separation motors within this programme. Presently, for Ariane 5, Avio serves as a subcontractor responsible for producing the liquid-oxygen turbopump used in the Vulcain 2 engine and the P230 solid-propellant motor, which functions as the first-stage booster in a dual arrangement.

Regarding the new European medium-to-heavy Ariane 6 launcher, Avio handles the P120C solid-propellant motor—shared with Vega C's first stage—which acts as a booster. This motor is configured in pairs for the medium Ariane 62 variant and in sets of four for the heavy Ariane 64 variant. Additionally, Avio produces the liquid-oxygen turbopump (LOX) for the Vinci engine.

Ariane 6 conducted its inaugural flight on 9 July 2024.

Solid-Propellant Propulsion Systems for Air Defence Missiles

In October 2013, Avio entered into an agreement with MBDA, a European consortium specializing in missile and missile defence systems, to develop and manufacture the propulsion unit for the CAMM-ER (Common Anti-air Modular Missile Extended Range). Avio also supplies the booster engine for the Aster 30 missile, designed for both anti-aircraft and anti-missile applications.

Space Rider

The Space Rider project aims to develop a reusable orbital vehicle launched by Vega C that can remain in Earth orbit for several weeks before safely returning and landing on a runway. Currently in research and development stages, its initial mission is planned for 2023. This initiative began at the ESA Ministerial Conference in 2014, with Avio acting as Co-Prime Contractor alongside Thales Alenia Space.

HERA Mission

Avio is involved in ESA’s HERA mission, which focuses on investigating an asteroid to advance technologies intended for planetary defence against potential future asteroid impacts on Earth.

Stock Market Listing

On April 1, 2017, Avio completed its merger with Space2 and secured the necessary authorization from Consob to be admitted to the Milan Stock Exchange. This process involved Space2 acquiring 85.68% of Avio's share capital, with participation from Leonardo S.p.A. and In Orbit s.r.l.. Following this transaction, the company adopted the name Avio S.p.A.

The official stock exchange debut occurred on April 10, 2017. This transaction led to Leonardo Finmeccanica increasing its stake from 14% to approximately 28%. Additionally, over 40 managers became shareholders, collectively holding around 4% through the corporate entity InOrbit s.r.l.

Affiliates, Joint Ventures, and Investments

Avio maintains controlling interests or equity stakes in several entities, including:

• A 70% ownership in SpaceLab, a joint venture with the Italian Space Agency (ASI) focused on advancing new propulsion technologies;
• A 60% stake in Regulus, a French-registered company responsible for solid propulsion motor loading at the Guiana Space Centre;
• Equal partnership (50%) in Europropulsion, a joint venture with ArianeGroup managing European launcher integration in French Guiana;
• A 3% shareholding in Arianespace, the French firm providing European launch services and overseeing operations of Vega and Ariane launch vehicles.
