Indian HLV for Lunar Return Mission

This is a proposed idea within ISRO for an Indian Heavy Lift Vehicle(HLV), to bring 20 tonnes to lunar orbit, as part of a lunar return mission:

So as can be seen, the proposed configuration would be 4 semi-cryogenic engines of 460 tonnes each, surrounding an 800-tonne semi-cryo core first stage, with a 460-tonne semi-cryo stage above that, and finally a 100-tonne cryogenic stage on top.

This design configuration would be capable of lofting 100 tonnes to LEO, or 20 tonnes to Lunar Orbit. Shown on the left for comparison is India's upcoming GSLV-Mk3 medium lift vehicle, which would be used to demonstrate preliminary capabilities like orbital rendezvous, docking and EVA.
