Unique production of the FMG

700 years have passed since gunpowder was first mentioned in Granada. Production took place in a Spanish factory, making it unique in the defence industry.

The Fábrica de Municiones de Granada, as it is now known, has a wealth of experience that is hard to match. It has gradually developed into a comprehensive manufacturer of single and two-base propellants and propellant charges, rigid and liquid TNT, rockets, artillery and tank ammunition. At present, the main production programme is tank ammunition.

Tank ammunition

The main product of the FMG factory is tank ammunition. Its production started in the 1980s, initially focusing on smaller calibres. These became technologically obsolete over time. Currently, tank ammunition production is based on two calibres, 105 and 120 mm. Both meet the strict requirements of the STANAG regulation.

Mortar ammunition

The production programme of mortar ammunition consists of 60, 81 and 120 mm calibres. They are filled with TNT and powder charges. Completion, lacquering and final assembly is mainly done by hand, with workers able to complete up to 800 pieces per day.

Production of propellants, propellant charger and TNT

Nitrocellulose is processed at the factory into single and two-base propellants and propellant charges. It produces special M4A2 propellant charges for 155 mm calibre artillery ammunition. It consists of approximately 6 kg of M1 single-base propellant, a basic charge and four additional initiating charges, which are tied together with textile straps.

Conventional HE ammunition is dosed with liquid TNT, while the PFF (pre-formed fragmented) ammunition is dosed with rigid TNT in the form of rolls. The processing of both types of TNT takes place in the FMG.

Chemical laboratory and testing

An essential part of production is the chemical laboratory, where staff analyse all incoming raw materials. The ammunition produced at FMG is thoroughly tested, and they know exactly what it can take. From the moment it leaves the factory, it is exposed to extreme conditions – extremely long transport over difficult terrain, temperatures ranging from minus to plus 50°C, heavy drops and unexpected impacts.

Thanks to special transport simulation equipment, for example, they can see what ammunition looks like after 10,000 kilometres, and thanks to crash tests they know the durability of individual components.

FMG is not only a guarantee of quality but also of safety.

Is there a factory like this anywhere else in the world?
