I am unable to fully comprehend some parts of the part three of the series by Tarmak . Although as usual its a great piece and emphasises on the right areas.

The engineers are working on a new booster motor which will reduce aerodynamic forces and stresses induced on the HSTDV vehicle. This will allow the vehicle to be launched without any fairings. And the scientists are hoping to test this out in the very next launch.
As far I know, the stresses induced and aerodynamic forces are proportional to the booster speeds and the AoA of the cruise vehicle. Lower speeds means lower dynamic stresses and also lower skin drag . Lower kinetic heating .
So are you we to assume that the current booster takes hSTDV to a much higher Mach no during the later stages of flight regime. More than M6.5 . Which necessitates the use of the fairings . With a newer booster the peak velocity would be within the speed limits of the HSTDV. So a launch without any fairings can be attempted .
PS- This means our oballisticmissile tech from the late 90s and early 2000s and solid propellants science of that era is almost at par with other countries . We are so sophisticated that we need a new booster to be able to launch HSTDV without fairings . This is just awesome.
APJ KALAM is a legend of a legend. An ultra legend. If I bring a Dragon ball analogy here , HE is super saiyan four level.
He dreamt big on Hypersonics . He got his inspiration from Lord Krishna's lord
sudarshan chakra. He envisaged a hypersonic mother missile/drone which would carry smaller guided missiles warheads , take them to the general area, launch them and return back to base. Reusable .He was ahead of his time by 20-30 years . Even Uncle Sam with a defense budget that is almost two times of India's total budget doesn't have such a niche capability .
