Small Arms Ammunition Factory


The Small Arms Ammunition Factories were ammunition manufacturing plants run by the Australian government. Nearly all of their production was for domestic use by their military, the police forces, and government-appointed agents.

Founding (1888–1939)

In 1888 the Colonial Ammunition Company of New Zealand founded an ammunition factory in Footscray, a suburb of Melbourne, Victoria. During World War One from 1915 to 1918 the plant made over 2 million rounds of rifle ammunition a year. It was purchased by the Australian government in 1927.
The Defence Explosive Factory Maribyrnong opened in 1908. A factory annexe was built in 1912 to supply Footscray with domestically-produced cordite. It also had an ordnance annexe that produced artillery pieces, mortars, and shells. During World War One, the phrase "Made in Maribyrnong" referred to how central the town and its industries were to the Australian war effort.
The Footscray plant's headstamp was originally CAC from 1888 to 1918 and ->CAC<- from 1918 to 1920. The headstamp was changed to ->SAAF<- from 1921 to 1923 and one lot in March 1924, A↑F during 1924 to 1925, "↑F" from 1925 to 1926, and MF from 1926 to 1945.

World War Two production (1939–1945)

In August, 1939, a plan was created to expand native ordnance production in case a war cut Australia off from the rest of the Commonwealth. The antiquated ammunition plant at Footscray was to be abandoned as soon as a more modern and efficient factory was built nearby. To differentiate between them, in 1940 the old factory briefly received the designation of Munitions Factory No.1 and the new factory was designated Munitions Factory No.2. Demand forced the old factory to remain open until the war's end. The new factory would be the only one to remain open after the war. The plans to make one factory at Hendon was expanded to two factories that were built only a few hundred metres apart. Conversely, the original plans to make two small factories at Rocklea was abandoned and one large facility was made instead. The sixth and last factory at Welshpool received the designation of SAAF No. 6.
In 1940 the workforce at Footscray grew from a few hundred men to 6,000 men and women at its peak. Employees worked 12-hour shifts for six days a week. A women's hostel was opened across the street to house the female workforce and ensure continuous operation of the production lines. The Maribyrnong complex employed 20,000 men and women at its peak, with women making up 52% of the workforce.
Headstamp is the facility's code letters at 10 o'clock, the two-digit year of production at 2 o'clock, and the type and mark of cartridge at 6 o'clock.

Small Arms Ammunition Factories (SAAF)

The small arms ammunition factories were fed by specialized facilities designed to supply their components.
In 1945, the original old Footscray ammunition factory was finally closed, as were the facilities at Hendon, Rocklea, and Welshpool. The second Footscray facility was later redesignated from MG to MF in 1949.
In 1986 Albion Explosives Factory was closed due to suburban encroachment. Production was moved to Mulwala Explosives Factory, New South Wales in 1988. Mulwala Explosives Factory was privatised in 2011 and then bought out by Thales Australia Ltd.
In 1989 the Australian government nationalised munitions manufacture under a government-owned company called Australian Defence Industries . Its first round of business was to consolidate and regulate ordnance production. The Explosives Factory Maribyrnong complex was closed during restructuring later that year.
Production at Ammunition Factory Footscray was slowly wound down beginning in 1991 until it was closed in 1994. A new factory run by Australian Defence Industries was opened elsewhere at Benalla, Victoria. When ADI was bought out by Thales in 2006, ADI was renamed Thales Australia Ltd. In 2012 Thales Australia spun off its factories at Benalla and Mulwalla to form the Australian Munitions group. It is also responsible for managing any Australian military logistical functions involving munitions.
Benalla still uses the ADI headstamp from 1994 to as recently as 2014. Production of 5.56mm NATO F1 Ball resumed in 1995 and F1A1 Ball began in c.2010. Both cartridges are similar, but the F1A1 ammo has a green meplat tip and the headstamp has dimples at the 3 and 9 o'clock position. 5.56mm NATO F3 Blank production began in 1998 and is produced in batches every three years. Production of.50 BMG M33 Ball began in 1999 and 7.62mm NATO F4 Ball began in 2008. Since they now only produce Ball ammunition, headstamps since 1995 only include the contractor code at 12 o'clock and the two-digit production year at 6 o'clock. It also produces 20mm autocannon rounds and will possibly begin production of 81mm mortar shells as part of a 5-year reorganization plan.
Since 2014 Australian Munitions produces civilian market ammunition under the Australian Outback brand. Civilian ammunition is in.223 Remington,.243 Winchester,.300 Blackout, and.308 Winchester and military surplus is in 5.56mm NATO F1A1 Ball and 7.62mm NATO F4 Ball. The civilian cartridges use Sierra- and Swift-brand match and hunting bullets with a special high-temperature-tolerant propellant.
