(ORDO NEWS) — The US Air Force has awarded Leidos a $334 million contract to design and develop the Mayhem hypersonic drone to replace the legendary SR-71 Blackbird.
Interestingly, the drone will be equipped with a hypersonic ramjet engine (scramjet), so Mayhem will not be able to take off on its own.
To achieve hypersound, it will first accelerate with the help of a special rocket, and only then launch the main scramjet.
