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.
 
Why is there also reference to 155 mm projectiles in the document?
 
Do we have any idea of what the range of this is supposed to be?
 
Seen as a SFIRR tested on may 8th, phase 2 in progress with navair “We believe that the SFRJ is going to be a game-changer for the US Navy and our Allied partners, and we are excited to see the successful THOR-ER flight tests,” said Stephen Farmer, Director for Advanced Concepts, Prototyping & Experimentation at Naval Air Warfare Center Weapons Division (NAWCWD). “We are also humbled in having this partnership with the Norwegian Ministry of Defence and Norwegian industry partner Nammo.

in 2020 they quoted 400km+ for the AA proposal, Its a strike weapon however now. AMRAAM AXE is still unknown in its progress
