OPM, other people's money. Another fake it until you make it which seems to never end when the cash is all over the place.

Most of what you see is a revamp of SSJ design over the last 20 years.

Time will tell.

I am curious, do you have something more original?

Well, by crossing this first milestone towards real life hardware testing at least they proved they're not a scam, and already accomplished more than the folks at Aerion could have ever dreamed of, literally, whom never seemed to take their vision seriously, beyond only showcasing shiny renders and crazy ideas like "Mach 4 airliners "with no physical product until they went bust, so there is hope.

So, are the drones still QSP after the redesign or just "Supersonic"? They must've found the early footprint to be horribly impractical in real-world environments, so unless the plane already came with the feature of being able to be folded in two from a hinge in the midsection, this thing would have been too long to reasonably fit under most fighter shelters.

Exosonic Awarded USAF SBIR Phase 2 Contract

--AFWERX selects EXOSONIC, INC for a Small Business Innovation Research Phase 2 contract to develop a digital design and trade study for a fifth-generation supe

www.asdnews.com

The U.S. Air Force Research Laboratory (AFRL) has awarded Exosonic, Inc. a $1.250 million contract to initiate the design and development of a supersonic fifth-generation target. This contract was awarded under the AFRL’s Small Business Innovation Research (SBIR) program.

In a Direct-to-Phase II SBIR, Exosonic will perform a design study that will include an analysis of alternatives and reuse options related to major subsystems, including propulsion, avionics, and landing gear. The results of the effort will be to create a viable design and a path to prototyping and development of the aircraft.

Based on all the QSP test articles that have shown reductions in boom levels, I doubt that the updated design is going to be particularly quiet.

All the boom mitigation tech requires a very long fuselage, and annoyingly does not support area ruling(!)

The revised design shares a similar lumpy rear to that of theBoeing Icon III project, so maybe the QSP is still there, or on a reduced scale, but not publicly advertised anymore:

My concern is the much shorter nose, unless they decided to do something like the Quiet Spike?
