Ariane 6, in its different Ariane 62 and 64 configurations, is a new launcher which will debut in 2020 and will replace Ariane 5 in 2023.
During the conference held by the Ministers of the ESA member states in December 2014, the development programme of the new Ariane 6 launcher was approved and signed. The launcher will debut in 2020 and will replace Ariane 5 in 2023. Ariane 6 will be equipped with two different configurations, Ariane 62 and 64, which will have a different payload.
Ariane 62 is designed to orbit 5-ton payloads, while Ariane 64 is designed to orbit 10.5 tons in Gto.
The launcher will be equipped with a main motor, derived from the current Vulcain 2 cryogenic motor, with the new Vinci higher stage and two or four side motors with a solid propellant, P120 C (same as Vega), respectively for the Ariane 62 and Ariane 64 configurations.
