Built by people willing to move first.
Volaris Defence Technologies exists because sovereign loitering capability wasn't going to build itself. We started with the ULM-45 Jäger, and with a simple position: capability comes from doing the work, not from waiting for a mandate.
Steven J MacDonald
The Jäger's flight-control approach draws on seventeen years of RC aircraft design and hands-on UAV fabrication, across Betaflight, ArduPilot, and PX4, backed by commercial UAV operations experience in South-East Queensland and a decade in the UAE. Steven holds a CASA RePL with sub-25kg endorsement.
That background sits behind a simple observation: Australia talks about sovereign defence capability more often than it builds it. Volaris exists to close that gap, not wait for it to close itself.
The ULM-45 Jäger began as a question rather than a product brief — what would a man-portable loitering system look like if it were designed from first principles, for the way small units actually operate in the field, instead of scaled down from a larger programme.
Volaris is based in Queensland, with the Jäger's architecture finalised and sub-scale flight testing complete. The next phase is about proving the system in front of the people who need to see it work.
Mark MacDonald
Volaris draws on advisory support from Mark MacDonald, a retired RAAF Warrant Officer whose fifteen years of service began as a radio technician on F-111 aircraft, maintaining radar and guidance systems, before moving into aircrew roles across rotary and fixed-wing platforms: gunner on the UH-1, then loadmaster and, later, flight engineer on the CH-47 and C-130.
That was followed by thirty-two years in commercial aviation with Cathay Pacific and Emirates, most recently as an A380 Captain and Synthetic Flight Instructor and Examiner, training and assessing other pilots on the fleet. His background extends into weapon systems and their operational use, and into defence procurement and doctrine, brought to Volaris in an advisory capacity.
Queensland, Australia
Volaris is built in Queensland by design, not default. Sovereign capability means capability that exists inside Australia's own industrial base, not capability that's licensed, imported, or promised for later. Building here is part of the argument, not just the address.
