Arun, Two reports from Hindu(TSR & YM) and TOI (Rajat Pandit) say terminal velocity was 7km/sec. The re-entry was powered with the conical motor! MARV(ellous) I would say.

And ICBM velocities in non-MARV mode.

Great!!!



These two report confirm:

1. The third stage was conical

2. Third stage fired during re-entry, meaning it did MaRV/BgRV

3. 7 km / sec re-entry speed meaning its a full ICBM

4. precision of few meters (not few tens of meters)

5. All three stages were composite motors. Not clear if all three stages were carbon composite or only the upper stage was carbon composite. That pumps up teh mass fraction of these motors in high 90 percents, tremendously increasing the total impulse delivered to payload.



"Quote:

These included rocket motor casings made up of carbon composites, the motors contoured to suit the missile's shape, high-performance navigation, guidance and control systems and rail/road mobile launcher.



.... .. Dr. Sekaran, the chief designer of the missile, stressed that the rocket motor casings made up of carbon composites gave the missile a better performance.



6. the 3rd stage was carbon composite, meaning it was capable of taking on Max-Q temperature stress during powered BgRV style flight profile.

7. IOW flight was BgRV to make it ABM resistant:



Quote: DRDO has also worked to reduce the radar and other ''signatures'' of missiles like Agni-IV and Agni-V to make them ''much more immune to counter-measures''.
