Hypersonix has raised $46 million in Series A funding to advance its hydrogen-powered hypersonic aircraft program.
The Brisbane-based startup secured backing from the National Reconstruction Fund Corporation, which contributed A$10 million in its first defence-sector investment.
UK-based High Tor Capital co-led the round alongside international investors including Saab and RKKVC, showing global confidence in Australia’s aerospace innovation.
The company develops the SPARTAN scramjet engine, a fully 3D-printed reusable hydrogen engine capable of reaching speeds up to Mach 12 with zero emissions.
Funds will accelerate development of Hypersonix’s DART AE prototype, set for a NASA- and US Department of Defence-supported test under the HyCAT program.
The company also plans to expand its Queensland manufacturing facilities and advance its next-generation aircraft, VISR, for surveillance and delivery missions.
Founded in 2019 by David Waterhouse and Dr Michael Smart, Hypersonix employs about 45 people in advanced aerospace and manufacturing roles.
CEO David Waterhouse said the investment positions the firm to lead in sustainable hypersonic flight and strengthen Australia’s sovereign defence manufacturing base.
The funding signals growing international interest in hydrogen-based hypersonic propulsion and Australia’s push toward defence-led clean aerospace technology.
The milestone reinforces Hypersonix’s role as a front-runner in the race to commercialize reusable, zero-carbon hypersonic aircraft.
