The mission will see DART AE, Hypersonix’s 3.5-metre autonomous hypersonic aircraft, carried into the upper atmosphere aboard Rocket Lab’s HASTE rocket, purpose-built for hypersonic test missions. At the planned deployment point, DART AE will separate and SPARTAN will ignite, powering the aircraft through its hypersonic flight profile.
The flight is scheduled from Rocket Lab Launch Complex 2 at the Virginia Spaceport Authority’s Mid-Atlantic Regional Spaceport, within the NASA Wallops Flight Facility, on Wallops Island during a launch window that opens at 4pm Eastern on Wednesday, February 25th (8am AEDT on Thursday, February 26th)
Named Cassowary Vex by the Defense Innovation Unit and That’s Not A Knife by Rocket Lab, the mission is being conducted on behalf of the US Department of War’s Defense Innovation Unit (DIU).

Dr Smart said the flight represents a decisive step beyond laboratory and ground validation.
“This mission takes our propulsion, materials and control systems into the real hypersonic environment,” Dr Smart said.
“At these speeds and temperatures, there is no substitute for flight data. What we learn from this mission will directly inform the next generation of reusable hypersonic aircraft.”
Hypersonix CEO Matt Hill said the countdown marks a significant milestone for both the company and Australia’s advanced aerospace capability.
“Flying DART AE is a major moment for our team,” Mr Hill said.
“It reflects years of focused engineering and confirms that an Australian company can design and build technology capable of operating in one of the most demanding flight regimes on Earth.”
The mission follows Hypersonix’s $46 million Series A funding round, backed by Australia’s National Reconstruction Fund Corporation and Queensland Investment Corporation. The round was led by High Tor Capital, a UK investor in national security and frontier technology, with European defence company Saab and Polish family office RKKVC also supporting the raise.
The funding is accelerating Hypersonix’s flight test program, expanding advanced manufacturing capability in Queensland and fast-tracking development of the company’s next reusable hypersonic platform, VISR (Velos Intelligence, Surveillance and Reconnaissance). Hypersonix employs more than 50 people in Brisbane across aerospace engineering, advanced manufacturing and testing roles.
