A new experimental hypersonic cruise vehicle could be flying as soon as next summer under an initiative from the U.S. Defense Innovation Unit (DIU).
The Dart AE high-speed test aircraft is being developed by the Australian company Hypersonix Launch Systems following the award of a prototype contract by the DIU.
DART AE is a 9.8-foot-long (3 meters), 660-pound (300 kilograms) scramjet-powered technology demonstrator that can reach speeds of up to Mach 7, according to the company’s website. (Mach 1 is the speed of sound, which is about 767 mph, or 1,235 kph, at sea level. “Hypersonic” generally refers to flight that achieves speeds of Mach 5 or higher.)

The vehicle could now be ready as early as next summer as part of Pentagon efforts to boost its hypersonics flight-test cadence, C4ISRNET reported.
The DIU, which operates under the U.S. Department of Defense, describes itself as an organization focused on accelerating the adoption of commercial and dual-use technology to solve operational challenges at speed and scale.
The Pentagon is pursuing research and development of hypersonic defense programs. As part of this, the DIU has rolled out the high-cadence testing capabilities (HyCAT) project, which brings opportunities for commercial companies to develop reusable and low-cost test vehicles and reduce strain on DoD resources.
Lt. Col. Nicholas Estep, HyCAT program manager, told C4ISRNET that the DIU is refining the details of the mission, including the flight conditions, the launch provider and the location for next year’s first fully integrated, autonomous flight of DART AE.
Fenix Space, Inc., located in San Bernardino, California, and Rocket Lab, located in Long Beach, California, have also been awarded DIU contracts for a reusable tow-launch platform and the Hypersonic Accelerator Suborbital Test Electron (HASTE) rocket, respectively.
