Hypersonic Aircraft, DART AE 001

Supposedly, testing is happening this year. It's not clear though is they are talking about Summer in Australia (Jan-Feb (beginning of 2024) or Dec (end of 2024)), or in the US (June - Aug).

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.)

Does anybody know what a "tow-launch" platform is?

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

I think they mean towing it to altitude like a glider and then releasing it to fly freely.

It allows for a larger aircraft than dropping it from another plane like Stratolaunch and Roc, but it’s riskier.

Edit: yep, that’s exactly what they’re aiming for:
