new energy for defense

Following the shutdown of the plants in 2017, the General Directorate of AID launched, with the support of highly qualified private companies, an intensive planning phase aimed at ensuring the restart of the production facilities.

In 2024, with the recommissioning of the hydroelectric power plant, electricity production was brought back into operation through an agreement signed between AID and Enel Green Power Italia.

The detailed design phase for the revamping of the spherical powder production plant is currently nearing completion, and operations are expected to resume within two years. Preparatory activities are also underway for the design and refurbishment of the other two plants dedicated to the production of energetic materials.

In addition, a significant remediation programme is currently being carried out in certain sections of the plants and in internal areas of the facility.

history

HISTORICAL ORIGINS OF THE FACILITY

The Military Propellants Production Facility of Fontana Liri originated from the need, at the end of the nineteenth century, to build a new military production plant in a location protected from external threats yet rich in water resources, intended to replace the previous facilities in Scafati and Fossano.

The decision by the specially appointed ministerial commission to identify Fontana Liri — and more specifically the area known as Madonna degli Zapponi — as the most suitable site was based on a comprehensive assessment, which concluded that the location met all strategic and industrial requirements.

The natural drop of the River Liri would ensure the establishment of an autonomous energy supply necessary to power the plants, whose construction began in November 1891.

Once construction works — which lasted approximately one year — were completed, skilled workers from the Precision Laboratory of Turin and from the decommissioned powder factories of Scafati and Fossano moved to Fontana Liri to oversee the installation of machinery, a preparatory step prior to the start of industrial operations.

Thus, when production of the well-known Model 1891 rifle, 6.5 mm calibre, began in 1894, while the Capua Pyrotechnic Establishment was responsible for the manufacture of powders, the Liri powder Factory handled the preparation of the metal components and primers, as well as the assembly of the cartridge.

The growth in manufacturing activity in a locality such as Fontana Liri soon became a genuine socio-economic driver, fostering the development of a substantial workforce of skilled labourers and supporting the expansion of the plants, which also benefited from a hydroelectric power station and steam boilers.

The strategic importance of the site was further confirmed by the establishment of a local Artillery Command, which in 1894 became the Artillery Directorate of the Powder Factory.

Production growth was also driven by continuous experimentation with chemical compositions and finished products, which were systematically tested at the ballistic level. For this reason, in 1898 a small-calibre firing line was constructed — in the area still known today as “Tirocannone” — although it soon proved inadequate and was replaced four years later by a fully equipped firing range.

In 1904, the facility was renamed the Royal Powder Factory on the Liri and expanded its research, development and experimentation of new products. Its efficiency was further confirmed in 1909 with the establishment of a High Technical-Scientific Supervisory Committee, structured into a chemical division, a mechanical division and an administrative service.

On the eve of the First World War, the workforce numbered just under 500 employees, all exempt from military mobilisation due to their specialised expertise, which was difficult to replace in wartime.

The quantitative and qualitative increases achieved during the conflict, however, proved excessive once peace was restored. Starting in 1919, there was a sharp reduction in production activities and personnel due to the inevitable decline in demand from the Armed Forces, which were already supplied with substantial quantities of surplus war material to be disposed of.

For this reason, during the 1920s, the Powder Factory’s activities were therefore largely limited to the reprocessing or disposal of materials originating from the war front.

The situation changed during the 1930s, when renewed national ambitions led to a significant renewal of ammunition stocks. Between 1936 and 1938 in particular, experimentation with new explosive components resumed with intensity in order to meet the various military commitments in which the Italian Armed Forces were engaged.

This support increased further with Italy’s entry into the Second World War, which led to a rise in orders and an expansion of production lines, requiring shift work to ensure uninterrupted production. Given the strategic importance of the site, adequate anti-aircraft defences were also installed, as frequent enemy bombing raids increasingly affected plant operations.

The situation became even more critical following the proclamation of the Armistice on 8 September 1943. German occupying forces swiftly seized the Powder Factory with the aim of dismantling the machinery and transferring it to northern Italy, which was under their strategic control. Subsequent Allied bombings further damaged what remained of the facilities.

Only after the front line had moved on was Fontana Liri able to resume industrial activity, including that of the destroyed and looted Powder Factory.

Reconstruction of the manufacturing complex began in the summer of 1944, and within a few months operations resumed, primarily focused on the detonation and neutralisation of unexploded ordnance.

The post-war period was characterised by ongoing changes, at times raising the prospect of closure, despite the high level of specialisation achieved in the production of propellants for artillery and small arms. It was precisely the excellence developed in this field that led the military administration to relaunch the Fontana Liri industrial site.

After undergoing two changes of name, in 1984 it became the Military Propellants Production Facility, thereby regaining a more prominent position within the auxiliary manufacturing structure of the Armed Forces. Since 2002, it has operated under the authority of the Defence Industries Agency (Agenzia Industrie Difesa).

THE RIVER LIRI AND THE HYDROELECTRIC POWER PLANT

Approximately 120 kilometres in length, the River Liri flows through the regions of Abruzzo, Lazio and Campania. This natural resource has always formed the foundation of the activities of the Military Propellants Production Facility.

The hydroelectric power plant located within the Agency’s premises represents an excellent resource for the production of clean energy.

Over the years, its output has ensured significant financial returns, which the Agency has reinvested in the local area and in the development of new projects.

The plant consists of three Kaplan turbines, each with a generating capacity of 1,480 kW.

Water is drawn directly from the River Liri, immediately downstream of the discharge of the Enel Green Power Italia hydroelectric plant known as the Fontana Liri Power Plant. Downstream of the intake basin, three penstocks channel the water to the three hydroelectric generating units, after which it is released through a return structure consisting of a channel equipped with three discharge gates.

Following a shutdown of approximately three years to ensure compliance with safety regulations and technical standards, a contract was signed in 2022 between the Defence Industries Agency and ENEL GREEN POWER ITALIA S.r.l. for the reactivation and management of the Facility’s hydroelectric plant. The agreement guarantees energy availability for the entire duration of the concession, as well as a fee on surplus electricity generated by the plant.

Electricity production was restarted in 2024.
