That will be SHLV, not included in NGLV portfolio yet.
It might have 4-8 clustered SCE-200 at core (or a bigger semi cryo engine) and Vikas X engine boosters in place of S200 (booster being same as size of LVM3) and a far more powerful cryogenic upper stage. 60-130 tonnes in LEO.
SHLV will come around in 2040s.
2*CE-20 engines will be enough for upper stage of SHLV.... configuration might be as below..
1st stage : 2*SC400 boosters + 1*SC400 core stage each powered by 4*SCE-200 engines, total 12 engines.
2nd stage : SC120 powered by single SCE-200
3rd stage : C-60 powered by twin CE-20s
The above configuration is exactly similar to Chinese Longmarch-5DY which is being planned for their manned lunar mission, only difference is that they use 7*YF-100 engines in core stage ,while for us, 4*SCE-200s are enough , because our SCE-200 is far more powerful than their YF-100.
2 such SHLVs are required for manned moon landing, one to carry the lander and the other for manned spacecraft...as far as I understand, our current Gaganyaan spacecraft won't be suitable for manned lunar mission.....we would need an entirely new spacecraft for that... Gaganyaan weighs 7.8 tons at Max ...while our future gen manned spacecraft should weigh around 20tons.
