THOR-ER (Solid fuel ramjet.)

Yes thats why i hope its gonna be solid fuel or gel but gel types are like magic.

As in do all kinds of fantastical things on paper but not so much in reality?

Kinda. A lot of development still is needed and many applications were atleast years ago not good enough for the investments. And a good amount of those studys Work with hydrazine which .... well is hydrazine. Also gel fuels need tanks with higher pressures and while many concepts use metal additives those are not easy to handle either. And except for ramjets (or similiar) there not many other applications for military use.

The last edition of Sutton's book on rocket propulsion didn't even have gel propellant in it. (The previous did.)

Yeah little investment in IT given that there anything but simple. For example an german rocket concept used an small SRM / gas generator to get the needed pressure to use it.

8 inch, I thought is was to be 10 inch?

I think that's the phase-2 flight vehicle. The paper is linked in my last tweet.

Why is there also reference to 155 mm projectiles in the document?

Nammo was also working on a ramjet assisted 155mm projectile IIRC .....

Do we have any idea of what the range of this is supposed to be?

It's a propulsion demonstrator and not a weapon prototype.
