NIOA recently completed armourer training and Serial Inspections of the cannons protecting HMAS Canberra – the OrbitalATK M242 25mm Chain Gun. The training and inspections were the first conducted on M242 cannons in NIOA’s new state-of-the-art weapon support facility near Brisbane Airport, and were overseen by RAN personnel.

Greg Toms, NIOA’s Technical and Armoury Services Manager, said “It was a great opportunity to have NIOA staff accredited by OrbitalATK to conduct this activity and to commission our support capability for medium calibre cannons here in Brisbane.  The facilities we have for repair, maintenance and test firing of medium calibre cannons are second to none in Australia.  Successful completion of the required Series Inspections on these cannons demonstrates that we have the capability to support the entire range of OrbitalATK medium calibre cannons up to 40mm, including those being offered for LAND 400.”

With the opening of NIOA’s new facility in July 2014, this type of training and maintenance activity is quickly ramping up.  The new facility features:

  • The largest secure weapons storage, maintenance and repair facility in Australia
  • Over 5,000 square metres of high security Defence accredited warehousing space
  • Optics repair centre and heavy grade weapons repair facility
  • 100m indoor test fire range for up to 40mm cannon
  • 200 seat training auditorium
  • Integrated logistics support capability with ready airside access

NIOA was appointed by OrbitalATK as their exclusive distributor in Australia and New Zealand for a broad range of products and services in January 2013. The range of OrbitalATK products represented by NIOA includes ammunition, medium calibre gun systems, gun and bomb fuses and specialist weapon systems. 

NIOA has the capability to support OrbitalATK’s range of advanced medium calibre cannons in our new facility, including the M242 25mm cannon and potential candidates for L400, the MK44 30/40mm and Bushmaster III 35/50mm cannons.  As well as supply of cannons, we also offer training, spare parts and through life support in country.
