=== Development ===
ISRO initially planned two launcher families, the [[Engineering:Polar Satellite Launch Vehicle|Polar Satellite Launch Vehicle]] for [[Astronomy:Low Earth orbit|low Earth orbit]] and [[Astronomy:Polar orbit|polar]] launches and the larger [[Engineering:Geosynchronous Satellite Launch Vehicle|Geosynchronous Satellite Launch Vehicle]] for payloads to [[Astronomy:Geostationary transfer orbit|geostationary transfer orbit]] (GTO). The vehicle was reconceptualized as a more powerful launcher as the ISRO mandate changed. This increase in size allowed the launch of heavier communication and multipurpose satellites, [[Astronomy:Human-rating certification|human-rating]] to launch crewed missions, and future interplanetary exploration.<ref>[https://www.ndtv.com/india-news/isro-not-to-fly-living-being-before-actual-manned-space-mission-official-1916654 ISRO Not To Fly Living Being Before Actual Manned Space Mission: Official].

===Human-rating===
While the GSLV Mk III is being human rated for [[Engineering:Gaganyaan|Gaganyaan]] project, the rocket was always designed with potential human spaceflight applications in consideration.
