Quarterhorse Hypersonic Aircraft Expected to Fly Mach 5

Hermeus is under a six hundred million dollar contract

In 2018 a group of former members from SpaceX, Blue Origin, and Generation Orbit got together and made a little company called Hermeus.  Hermeus is under a six hundred million dollar contract from the United States Air Force to build a hypersonic aircraft called the Quarterhorse. Which is expected to fly faster than Mach 5.

What does any of that mean, though?

They expect to hit that Mach 5 mark using a Turbine-Based Combined Cycle engine, or TBCC engine, built around a commercial GE J85 turbojet engine. What does any of that mean, though? Well, a TBCC engine uses your average turbojet to get to those high speeds, wherein a ramjet would ignite while climbing to hypersonic speeds.  The Quarterhorse is still a way out, with the company estimating a flyable prototype out sometime this decade.
