Main Data | Ariane 5G |
|---|---|
Height | 46 to 52 m depending on upper composite configuration |
Diameter | up to 5.4 m |
Liftoff mass for a double launch | 746 tonnes |
Payload mass for a dual launch, including mass of spacecraft and adaptors | 6 tonnes to Geosynchronous Transfer Orbit (580 km x 35786 km x 7°) 9.5 tonnes to Sun Synchronous Orbit (800 km x 800 km x 98.6°) |
Ariane 5 made its first successful launch on 30 October 1997. Its first operational flight took place in December 1999 when it launched ESA’s X-ray Multi-Mirror (XMM) satellite. Ariane 5 launched satellites for communications, Earth observation and scientific research.
Ariane 5 was used for launches into geostationary transfer orbit (GTO), medium and low Earth orbits, Sun-synchronous orbits (SSO) and Earth-escape trajectories.
All Ariane 5 versions were composed of a central core stage to which two solid boosters were attached. On top of this, different upper stage configurations were used.
In order to launch Ariane 5, ESA built a new launch site at Europe’s Spaceport near to the town of Kourou in French Guiana, as well as facilities to integrate the solid boosters and to produce the solid propellant used by the boosters.

Ariane 5 boosters (EAP)
The Ariane 5 solid propellant boosters were the largest solid rocket boosters ever produced in Europe.Weighing 37 tonnes each when empty, they were 31 m high and 3 m in diameter. Each booster, or EAP as they are referred to from the French Etage d'Acceleration à Poudre, contained about 238 tonnes of propellant. Ariane 5 boosters provided 1100 tonnes of thrust, roughly 92% of the total thrust at liftoff.
Ariane 5 cryogenic main stage (EPC)
Ariane 5’s cryogenic main stage is referred to as the EPC from its title in French, Etage Principal Cryotechnique. The EPC was 30.5 m high with a diameter of 5.4 m. When empty it weighed only 12.5 tonnes and approximately 170 tonnes when full of propellant.
Ariane 5 Vulcain engine
The Vulcain engine represents more than 30 years of technological development in cryogenic liquid propulsion. It constituted a major programme in itself and accounted for a quarter of the total investment made on the initial Ariane 5 development programme. Altogether 40 different European companies, led by France's Snecma Moteurs, contributed to the programme.
