ISRO’s heavy lift launcher, GSLV MkIII is identified for the Gaganyaan Mission and the process for human rating of GSLV MkIII is in progress. The high thrust solid propellant strap-on boosters S200 play an important role in the Human Rated GSLV MkIII. In order to human rate the booster, many new design features have been introduced in the hardware.

In yet another successful industry collaboration, the first critical booster segment of the motor case with a diameter of 3.2 meter, 8.5 meter in length and weighing 5.5 tons has been indigenously developed and delivered by L&T to ISRO. This is the first step towards the Unmanned Space Mission and was flagged off on November 13, 2020 by Dr. K. Sivan, Secretary, Department of Space and Chairman ISRO, and Shri. Jayant Damodar Patil, Director & Senior EVP Defence & Smart Technologies, L&T.
