Is that a capsule on top?.
2 X SCE-200 (Clustered) --> SC400 Stage
Mr. Somanath said that, eventually, ISRO will phase out Vikas by replacing it first in Mk-III with a cleaner and safer semi-cryogenic engine. The semi-cryo engine is ready for trial; its stage has just been approved. "I cannot predict when it [the replacement] can happen," he said.

Hmm, I wonder if that means the SCE-200 will also replace the Vikas engine on PSLV.
^^^Design looks very different compared to renders from recent years, are you sure that is SCE-200 and not some other engine?

The engine version that was used for Ukrainian fork of RD-120 Family development might be what is shown there. Also was a version developed in response to AJ-26 failure and larger version for LRB competition of SLS but since foreign made was not taken seriously by the US. Russian Space Web archives some versions well. The Russian successor fork of the former joint Soviet RD-120 family is here however MoD RD-120K version is omitted: https://www.trade.glavkosmos.com/catalog/launch-vehicles/engines/liquid-fuel-rocket-engine/

Either way if it is SCE-200 in that video then we can expect ground tests to start next year.

Either way if it is SCE-200 in that video then we can expect ground tests to start next year.RD-870 is the RD-120 copy.https://yuzhnoye.com/en/technique/rocket-engines/steering/rd-810/RD-120 was developed by Energomash working hip to hip with Yuzhnoye. After the RD-120K, Yuzhnoye designed their copy, he RD-870. Then an uprated single nozzle derivative, the RD-801. When trying to replace the RD-170 in the Zenith, they developed an uprated version of that, called the RD-810. And they sold those blueprints (but no method nor material formulas) to ISRO for the SCE-200. It is not clear if said development was paid by ISRO. What is known, is that RD-801/810 are mostly "theoretical" engines that were never built, much less tested and actually certified for operations.A little tidbit: apparently the Chinese got hold of a few copies of the RD-120 (throu a Russian company), and that's what they based their YF-100/115 engine on.
There have been reports that Yuzhnoye Design Office in Ukraine has been destroyed. Yuzhnoye is the manufacturer of the 1st stage Antares tank, so if these reports are true, then Antares will never be able to launch again after NG-19.
