MRO serves to maintain or restore components so as to avoid the need for complete system replacement. MRO activities may include unforeseen repairs as well as scheduled and preventative maintenance. For RUAG Australia, MRO is the combination of all technical and corresponding administrative, managerial, and supervisory actions necessary to return equipment to a ‘fit for purpose’ condition whilst, ideally, increasing the mean time between failures.

RUAG Australia’s capability comprises more than 25 different test benches, each capable of testing and simulating a variety of operational conditions. RUAG Australia also operates world-class cleanroom facilities (Class 10,000, Class 100) for performing precision metrology, sub-micron machining, finishing, assembly and testing.
