- The third stage of Vikram-1 produces a peak vacuum thrust of 100 kN (or ~10Tons) and has a burn time of 108 seconds.
- The rocket stage is built with high-strength Carbon fiber structure, solid fuel, EPDM thermal protection system, and carbon ablative nozzle.
- The rocket stage/engine has no moving parts and a high level of automation in manufacturing.
