Although single base propellants have been around for over 100 years, production of this type of propellant only began in Australia during World War 2, when appropriate equipment and know-how were provided under the USA’s Lend Lease Scheme. Prior to this date, all propellants had been of the British double base type. The Mulwala gun propellant facility in New South Wales was set up to produce these commodities, and remains the sole supplier of military-grade propellants and high explosives to the Benalla ammunition plant in northern Victoria. These plants are deemed to be strategic national assets, and produce ammunition for Australia’s Defence Forces; Mulwala also produces low-grade explosives and propellants for a few other customers, including America’s NASA.
Australia isn’t the only country looking to modernize single-source ammunition facilities from World War 2 or earlier. The USA is in the same boat. The Mulwala redevelopment project has finally received full approval, and work is underway – with the assistance of the same firm that owns the USA’s prime (and until recently, only) small caliber military ammunition production facility. Now, Thales will have the assistance of America’s 2nd supplier as well.
