# List of GSLV launches

This is a list of launches conducted by the Indian Space Research Organisation (ISRO) using Geosynchronous Satellite Launch Vehicle (GSLV) rockets. This list does not include LVM3 (formerly known as GSLV Mk III) launches, which can be found here.

## Notable missions
### GSLV MK. I flight D1

This was the first developmental flight of the GSLV Mk.I featuring Russian cryogenic engine KVD-1. It was used to place an experimental satellite GSAT-1 into the orbit. However, due to sub-optimal performance and lack of fuel the vehicle did not achieve the intended orbit and the satellite had to maneuver itself using onboard fuel to correct the shortfall. ISRO claims the launch to be successful. In a 2014 interview, ISRO Chairman K. Radhakrishnan attributed the failure to incorrect mixture ratio used in the cryogenic upper stage.

### GSLV MK. II flight D5

This was the second test flight with indigenous cryogenic stage CE-7.5 and the first successful launch with the CE-7.5. The flight lifted and successfully placed the 1,982 kilograms (4,370 lb) GSAT-14 into the orbit. This flight became the harbinger of successful launch with the indigenous cryogenic stage.

### GSLV MK. II flight F09

This was the fourth consecutive successful flight of GSLV Mk. II with indigenous cryogenic engine. The flight placed the regional satellite South Asia Satellite was previously named as South Asian Association for Regional Cooperation (SAARC) Satellite. The satellite was a gift from India to its neighbors to bolster Prime Minister Narendra Modi's neighborhood first policy. Afghanistan, Bangladesh, Bhutan, Maldives, Nepal and Sri Lanka are the users of the multi-dimensional facilities provided by the satellite.

## Flight history

As of 29 January 2025, rockets from the GSLV family have made 17 launches, resulting in 11 successes, four failures, and two partial failures. All launches have occurred from the Satish Dhawan Space Centre, known before 2002 as the Sriharikota Range (SHAR).
2001–2009 :
| Flight No. | Date / time (UTC) | Rocket, Configuration | Launch site | Payload | Payload mass | Orbit | User | Launch outcome |
| D1 | 18 April 2001 10:13 | Mk I | First | GSAT-1 | 1540 kg | GTO | INSAT | Partial failure |
| Developmental flight, payload placed into lower than planned orbit, and did not have sufficient fuel to reach a usable orbit. ||||||||
| D2 | 8 May 2003 11:28 | Mk I | First | GSAT-2 | 1825 kg | GTO | INSAT | Success |
| Developmental flight. ||||||||
| F01 | 20 September 2004 10:31 | Mk I | First | GSAT-3 | 1950 kg | GTO | INSAT | Success |
| First operational flight. ||||||||
| F02 | 10 July 2006 12:08 | Mk I | Second | INSAT-4C | 2168 kg | GTO | INSAT | Failure |
| One of the L40 strap-on engines failed at lift-off. Both rocket and satellite had to be destroyed over the Bay of Bengal after the rocket's trajectory veered outside permitted limits. ||||||||
| F04 | 2 September 2007 12:51 | Mk I | Second | INSAT-4CR | 2160 kg | GTO | INSAT | Partial failure |
| High roll rate build-up due control system malfunction on one L40 strapon resulted in premature shutdown of other strap-on stages. Due to an error in the guidance subsystem achieved orbit had lower apogee and inclination higher than expected. Orbit corrected through satellite, eventually the INSAT-4CR was placed in its slot. Satellite completed its planned design life while it was fully operational. ISRO claims this GSLV flight to be successful. ||||||||
| 2010–2017 |||||||||
| Flight No. | Date / time (UTC) | Rocket, Configuration | Launch site | Payload | Payload mass | Orbit | User | Launch outcome |

| F06 | 25 December 2010 10:34 | Mk I | Second | GSAT-5P | 2310 kg | GTO | INSAT | Failure |
| First flight of GSLV Mk.I (c). Aft shroud of upper stage engine bay disintegrated due to aerodynamic loads, snapping the electrical continuity to L40 strapons. Vehicle was destroyed by range safety officer after loss of control over liquid-fueled boosters. ||||||||
| D5 | 5 January 2014 10:48 | Mk II | Second | GSAT-14 | 1980 kg | GTO | INSAT | Success |

Second flight of GSLV with indigenous cryogenic upper stage (CUS) developed by ISRO's Liquid Propulsion Systems Centre (LPSC) was launched successfully on 5 January 2014. It was a launch with precision of 40 m (130 ft). All the three stages performed successfully.
