Ann: PEPR Lodged for Proposed Siviour Graphite Mine, page-285

Would certainly prove interesting. I think in a global supply standpoint there is merit, however, domesic military requirements won't place a dent in RNU's annual production. I mean our fleet of land-based vehicles would have to be well under 20,000 (including military vehicles and 'white' fleet). I can't see our large UAV drones exceeding 200-300 in the next 5/10 years and small UAV drones are not even worth mentioning in terms of graphite requirements.
Though Army did showcase an EV model of the Protected Mobility Vehicle (retrofit retired frame), Which could be sold to foreign partner forces However, for military applications there is still a long way to go for the development of a suitable logistic support capability.
