=== GSLV Mark II ===
This variant uses an Indian cryogenic engine, the CE-7.5, and is capable of launching 2500&nbsp;kg into geostationary transfer orbit. Previous GSLV vehicles (GSLV Mark I) have used Russian cryogenic engines.<ref>{{cite web|url=http://www.spaceflightnow.com/news/n1010/12gslv/|title=India may seek international help on cryogenic engine|last=Clark|first=Stephen|date=2010-10-12|quote=Besides the new upper stage, the GSLV Mk.2 launched in April was nearly identical to previous versions of the booster|publisher=Spaceflight Now|access-date=15 July 2011}}</ref>

For launches from 2018, a 6% increased thrust version of the Vikas engine was developed. It was demonstrated on 29 March 2018 in the [[GSAT-6A]] launch second stage. It was used for the four Vikas engines first stage boosters on future missions.<ref name=sfn-20180329>{{cite news|url=https://spaceflightnow.com/2018/03/29/india-tests-upgraded-engine-tech-in-successful-communications-satellite-launch/|title=India tests upgraded engine tech in successful communications satellite launch|last=Clark|first=Stephen|publisher=Spaceflight Now|date=29 March 2018|access-date=30 March 2018}}</ref>

A 4m diameter Ogive payload fairing was developed and deployed for the first time in the [[GEO Imaging Satellite|EOS-03]] launch on 12 August 2021, although this launch was a failure due to technical anomalies with the Cryogenic Upper Stage. This will allow GSLV vehicles to accommodate larger payloads.<ref>{{Cite web|title=GSLV-F10/EOS-03 Brochure|url=https://www.isro.gov.in/gslv-f10-eos-03/gslv-f10-eos-03-brochure|access-date=14 August 2021|website=ISRO}}</ref>

As of October 2024, ISRO has stopped selling GSLV Mk II Rockets. Eight known launches are planned with [[IRNSS|NVS]] Missions, [[Indian Data Relay Satellite System|IDRSS]] Missions, [[NISAR]] Mission, etc.<ref>{{cite web |url=https://x.com/ISROSpaceflight/status/1844724481958334841?t=La5vxZzAvABlXsIcGCoHRQ&s=08 |title=ISRO has stopped selling GSLV Mk II Rockets |work=X (Formerly Twitter) |access-date=11 October 2024}}</ref><ref>{{Cite web |title=Why ISRO chose GSLV for NISAR mission despite the launch vehicle's poor track record? |url=https://www.theweek.in/news/sci-tech/2025/05/20/why-isro-chose-gslv-for-nisar-mission-despite-the-launch-vehicles-poor-track-record.html |access-date=2025-05-27 |website=The Week |language=en}}</ref>
