S125 solid rocket motor
Historical ISRO S125 solid core motor used as the first-stage motor of the original GSLV Mk I, including GSLV-D1. The official D1 mission reference identifies HTPB propellant, 4,700 kN maximum vacuum thrust, and a 100-second burn; those figures are retained here without inferring dimensions for the motor from the stage table.
