Wallops Island, Virginia, USA -- Australian hypersonic flight pioneer Hypersonix Launch Systems (HLS) has successfully completed the first flight of its DART AE hypersonic aircraft, marking a major milestone in the development of advanced hypersonic systems.
The mission, titled That’s Not A Knife, lifted off at 7pm Eastern on Friday, February 27th (11am AEDT on Saturday, February 28th) from Rocket Lab Launch Complex 2 within the Virginia Spaceport Authority’s Mid-Atlantic Regional Spaceport on Wallops Island, Virginia, aboard Rocket Lab’s HASTE launch vehicle.
The flight was conducted under the US Department of War’s Defense Innovation Unit (DIU).
Hypersonic flight refers to speeds above Mach 5, more than five times the speed of sound. Hypersonix is developing a new class of autonomous hypersonic aircraft capable of sustained flight up to Mach 12. Its flagship DART AE is a 3.5-metre autonomous hypersonic aircraft designed to validate propulsion, materials, sensors and guidance systems in real hypersonic flight conditions.
During the mission, HASTE carried DART AE to the planned deployment point in the upper atmosphere. DART AE then executed its hypersonic mission, gathering invaluable technical data for the team to analyse in the coming weeks.
