Historic Hypersonic Test Flight by Australia
What happened: Australia’s aerospace company Hypersonix Launch Systems successfully conducted the first flight of its DART AE hypersonic aircraft/test vehicle on 28 February 2026 from Wallops Island, Virginia, USA.
New Atlas
Launch vehicle: The test craft was carried aloft aboard a Rocket Lab HASTE (Hypersonic Accelerator Suborbital Test Electron) rocket, nicknamed “That’s Not a Knife.”
New Atlas
Performance: After booster separation, the DART AE’s scramjet engine (SPARTAN) ignited, and the vehicle reached speeds of up to Mach 8 (eight times the speed of sound) at about 26 km altitude.
New Atlas
Flight profile: The mission flew roughly 1,000 km (about 621 miles) downrange before splashing down in the Atlantic Ocean.
New Atlas
Purpose: The flight was a technology demonstration designed to test propulsion, materials, and control systems under real hypersonic conditions, giving engineers valuable data to inform future designs.
New Atlas
Design highlights:
DART AE is fully 3D-printed from high-temperature alloys.
New Atlas
It uses an air-breathing scramjet engine powered by green hydrogen fuel, a more environmentally friendly option than traditional fuels.
