SCE-200 and Merlin have similar enough specific impulse. As for deep throttling, yes it won't go down to 40% but SCE-200 can throttle down to 60%. Rest, clustering should take care of it. And ISRO did say they are designing it with reusability upgrades in mind.

No matter, even if SCE-200 isn't fit for the job, continue to develop the methalox but in the meantime, they shouldn't abandon existing plans of HLV based on cluster of 4 or 5 SCE-200.

Also, we need SCE-200 class methalox if we want to build a Starship-Superheavy kind of stack. Raptor is similar thrust and specific impulse. And if we ever build a Moon rocket, it would make a lot of sense to go down the Starship-Superheavy route instead of the Saturn-V and SLS route. Even the Chinese realized this and have now modified design of the Long March 9.
Somanath sir confirmed that LPSC is developing a 80-100T thrust class throttlable Methalox engine

It looks like S. Somanath has finally completely taken over the ISRO.
So he's rescheduling and revising all programs as per his estimates.
Somanath sir said that there is already a team working with Industry to develop Next Gen Launch Vehicle. The design activities aren't started yet,but they are working on it

Good news, nice to hear it, but weren't the OneWeb sats supposed to be launched in October, at least this is what the SHAR official said( if not September, but it wasn't Nov-Dec) . Was it just a case of the OneWeb satellites not arriving in India.

Protocol for this sub-forum:
  1. New non-sticky thread for every new launch so that threads can be taken care off by timeline rather than congesting all at one place.
  2. Rocket modification at relevant rocket thread.
  3. Experimental/Exploration program at dedicated thread like Mars and Human spaceflight.
Members are requested to follow same so that navigation and layout of this sub-forum can improve. (I'm looking create a comprehensive board to attract some contributors from other forum).

Always post the images so that even if tweet gets deleted, record remains:-

(None of this is an official plan, just something being discussed as a possibility)

Who changed the owner yo?

Owner of the post. That was mine. Only a mod can change owner and date of post.
Dunno. I do remember posting those slides after looking at this post and then thinking it would be a shame if the tweet got deleted so I should post the images directly in DFI. I mean I positively remember making that post. Maybe you posted the same slides in another thread?
