‘That’s not a knife’: Australian hypersonic aircraft takes flight in space after US launch

In a landmark achievement for hypersonic technology, an Australian-engineered aircraft has successfully completed a suborbital spaceflight aboard a specialized rocket. The breakthrough mission, conducted through a partnership between Australian aerospace firm Hypersonix and US-based Rocket Lab, represents a significant advancement in high-speed flight capabilities.

The experimental flight, designated ‘That’s Not A Knife’ in a characteristically Australian reference, launched from Virginia’s Mid-Atlantic Regional Spaceport at precisely 11:00 AEST on Saturday. The mission utilized Rocket Lab’s HASTE (Hypersonic Accelerator Suborbital Test Electron) platform, a suborbital vehicle specifically engineered for test missions that reach space without achieving orbital velocity.

This launch marked Rocket Lab’s 82nd overall mission and their third successful launch this year, maintaining the HASTE program’s perfect success record through seven consecutive missions. The flight carried Hypersonix’s DART AE, a scramjet-powered aircraft designed to operate at multiple times the speed of sound in hypersonic flight conditions.

Brian Rogers, Rocket Lab’s Vice President of Global Launch Services, characterized the mission as “another proud moment for the HASTE team” and emphasized its significance as “a great showcase of the important commercial platform it has become for the Department of Defense.” Rogers further noted that “regular and reliable HASTE launches are helping to accelerate hypersonic readiness for the nation,” highlighting the program’s role in advancing United States space security capabilities.

Hypersonix CEO Matt Hill described the successful deployment of DART AE in an actual hypersonic environment as a “major milestone” for the company’s flight test program. This achievement brings the Australian aerospace engineering firm closer to its ultimate goal of delivering reusable hypersonic flight capability, potentially revolutionizing high-speed atmospheric and near-space transportation.

The collaboration between the Australian technology company and US space launch provider demonstrates growing international cooperation in advancing hypersonic technology, which has been identified as a critical national priority for the United States and its allies. The mission’s success provides valuable data that will inform future development of hypersonic systems for both defense and commercial applications.
