The GSLV-III or Geosynchronous Satellite Launch Vehicle Mark III (Hindi: भूस्थिर उपग्रह प्रक्षेपण यान एमके-३; also called LVM3) is a launch vehicle developed by the Indian Space Research Organisation (ISRO).

It is intended to launch satellites into geostationary orbit and as a launcher for an Indian crew vehicle. The GSLV-III features an Indian cryogenic third stage and a higher payload capacity than the current GSLV.


Development for the GSLV-III began in the early 2000s, with the first launch planned for 2009-2010. Several factors have delayed the program, including the 15 April 2010 failure of the ISRO-developed cryogenic upper stage on the GSLV Mk II.

A suborbital flight test of the GSLV-III launcher, with a passive cryogenic third stage, was successfully carried out on 18 December 2014, and was used to test a crew module on a suborbital trajectory. The first orbital flight is planned to take place in 2016.
