The semicryogenic engine is currently under development and the semicryogenic stage using this engine is expected to be qualified in the next five years. Whereas, an advanced space launcher that can deliver ten-tonne and heavier communication satellites to space requires a booster stage with clustered Semi-cryogenic engines.
The first developmental flight of the GSLV Mark-III vehicle i.e. GSLV MkIII–D1 is expected to be launched in the first quarter of 2017. The capacity to launch 4 tonnes will be achieved after a few developmental flights. GSLV MkIII–D1 will put a communication satellite namely GSAT-19 into orbit.
Approval is yet to be obtained for the development of the semicryogenic stage. The technical project report for initiating the approval process is under preparation.
