The Service Chiefs of Navy, Army and Air Force are accountable to the Chief of the Defence Force for the way that equipment is used by their Service. They are also accountable for the safety, fitness for service and environmental compliance of the equipment. The audit report deals with the way that the Service Chiefs are assured of the safety and suitability for service of the Australian Defence Force's (ADF's) ordnance systems. Ordnance systems include munitions such as missiles, shells and mines, and the auxiliary material necessary to aim, launch and guide munitions.
