How many times have ISRO's rockets flown?

94 orbital flights since 1993

PSLV 64, GSLV 19, LVM3 8, SSLV 3. LVM3 has not failed in 8 flights to orbit. PSLV's last two flights, in May 2025 and January 2026, both failed.

Record by rocket

Rocket	First flight	Flights	Failures, our count	Failures, ISRO's count
PSLV Polar Satellite Launch Vehicle	20 September 1993	64	5	4
GSLV Geosynchronous Satellite Launch Vehicle (Mk I and Mk II)	18 April 2001	19	6	4
LVM3 Launch Vehicle Mark-3 (once called GSLV Mk III)	5 June 2017 (first flight to orbit; a suborbital test flew on 18 December 2014)	8	0	0
SSLV Small Satellite Launch Vehicle	7 August 2022	3	1	1

Older rockets, SLV-3 (1979 to 1983) and ASLV (1987 to 1994), are not included. The GSLV row counts both the Mk I and the Mk II.

PSLV: 64 flights

Last success: PSLV-C60 with SpaDeX, 30 December 2024.

Date	Flight	Satellite	Counted as a failure by
18 Apr 2001	GSLV-D1	GSAT-1	Us only. The satellite was left short of its planned orbit. We count the launch as a failure; ISRO does not list it as one.

Frequently asked questions

Which is ISRO's most used rocket?

PSLV, the Polar Satellite Launch Vehicle. It has flown 64 times since 1993. ISRO calls it its "work horse".

Has LVM3 ever failed?

No. LVM3 has made 8 flights to orbit, all successful, including Chandrayaan-3 in July 2023. A suborbital test in December 2014 is not counted here.

Why do ISRO's failure numbers differ from yours?

On three flights the satellite reached orbit, but a lower one than planned: PSLV-C1 in 1997, GSLV-D1 in 2001 and GSLV-F04 in 2007. Our launch data counts those as failures. ISRO's launch lists do not. We show both.

What is the difference between PSLV, GSLV and LVM3?

PSLV mostly carries satellites to lower orbits, GSLV carries satellites of about 2 tonnes towards geostationary orbit, and LVM3 is the heaviest. See PSLV vs GSLV vs LVM3.

How many ISRO launches have there been in 2026?

See ISRO launches in 2026 and the 2026 scoreboard for every country.

How we count

Orbital flights only. Flight counts and dates are in UTC, so a late-night launch in India can show the day before.
"Our count" uses the same launch results as our 2026 scoreboard. "ISRO's count" is the flights ISRO lists as not successful.
We check these numbers by hand after each ISRO launch. The Updated line shows when we last did.
