2nd internal test should happen in near future, which is why we prob saw the integrated article. Not sure if they would publish or anything

HEMRL seem to have made progress in making better high energetic material for solid propellant fuel, specifically the Nitrate ester polymeric composite propellant, the NEPE based solid fuel used in western systems that they highly guard and never want to share outside of their circle. Previous research papers show indigenous work done on such compounds, as we know that drdo extensively use double base propellant for conventional systems and HTPB / composite propellant for strategic systems. These have reached a certain level in terms of specific impulse chiedly EDB being in 210-220 s range and composite propellant in the 240 s region, with the HTPB-AP-AL can demonstrate 240-245 s Isp.
Going beyond this and moving to nitrate ester polymeric compound based propellant, they have been able to show Isp in the range of 264-266 s which is a real progress , hence our new gen case bonded crmc look shorter and compact while keeping or bettering payload and/or reach. So as DRDO claim all the systems will likely get mk2 / NG whatever , where true veery long range systems will be possible without making the rocket look uncharacteristically big. So gradually from lab scale sample size, it is increased volume wise , casting method is developed, failure studies are conduucted and then finally when tech is mature it will flow into use for the futuristic very long range systems. It will be on par with the usa or french solid propellants in terms of isp range and burn rate/burn area eventually.

it seems they have been able to demonstrate at system level too now , possibly via in house testing or even flight test in the past year.

Quartz cyanate laminate and carbon phenolic laminate related papers , used as uhtc panels possibly. This will have increased application in many systems.
