General Dynamics spokesperson on Anduril as a company and their Collaborative Combat Aircraft offering,

“Sometimes you find these companies, and they say they’re going to use one drop of blood and they’re going to revolutionize the whole world, and then they grow up to be Theranos,” he said. “Quite frankly, when you look at the Fury — to me, it looks like trying to use a drop of blood to change the world. And I don’t see it.”

Pretty harsh comments lol!

Also,

He questioned how the Fury could carry weapons and host a landing gear with a large bottom inlet along the belly of the aircraft.

Interesting part: NG has selected Aerojet to supply the solid-fuel first stage and the reignitable upper stages for the hit-to-kill vehicle.
ie. hypergolic rocket motors
So as I suspected from earlier discussions of this program, TVCs and altitude control alone (such as on PAC-3 MSE) is not sufficient to counter gliders flying at the 'sweet spot' altitude of 60km, above the ceiling of PAC/SM-6 and below SM-3. This feature is important because it gives the interceptor the ability to make multiple burns and course corrections mid-flight to create a wider intercept envelope. But it will need to match or exceed the HGV's agility and velocity to intercept it reliably.

The DoD told me hypersonics were a gimmick.

This isn't really US Military related, but I figured I would stick it here since the company is US based.

Their potentially flight-altering idea is to instead use electric motors to separately drive the large fan and the engine’s combustor. That allows these two components to operate independently at whatever speed is optimal, rather than both being directly tied to the turbine core. This is possible now thanks to vast improvements in the size and efficiency of electric motors over the last couple decades, driven by advances in electric vehicles. These electric motors are powered by a turbogenerator, which creates electricity from a spinning turbine.

“The adaptive engine can behave either like a turbofan or a turbojet,” Brooke explained to Freethink. “It uses the electrical power from the turbogenerator to spin a fan. It can then also combust that air in varying increments to adjust how fast the air goes out the back. Between being able to slightly adjust the pressure from the compressor stage, and then hugely varying how much of that air we combust, we can have a thing that is both a pure turbofan and pure turbojet in one.”

The combination of electrical power and adaptability inspired the engine’s name: the Turboelectric Adaptive Engine.
