The World’s 1st Hypersonic Hydrogen Jet: What We Know So Far

Hypersonix Launch Systems is an Australian start-up that is turning heads in the hypersonic sector. Its current portfolio includes its unmanned DART, VISR, and Delta Velos demonstrator vehicles, all powered by its innovative hydrogen-powered Spartan scramjet engines. For now, the company is working to develop unmanned vehicles in partnership with allied militaries and NASA, although it also aims to bring hypersonic travel to commercial passenger aviation down the road. Separately, the hypersonic Lockheed Martin SR-72 spy plane in the works, successor to the Blackbird, is thought to be unmanned.
