The Ariane 5 GS is the latest evolution of the Ariane-5 Generic launcher, produced after the end of the Ariane 5 G+ series.
This version integrates more recent elements produced in the frame of the Ariane 5 ECA and Ariane 5 ES ATV developments. It incorporates:
- EAP boosters with more propellant in the S1 segments
- a composite VEB with the electrical equipments identical to those produced for the Ariane 5 ECA version
- an EPS stage loaded with 300 kg more propellant
The central core stage (EPC) uses the Vulcain 1B engine which delivers a thrust level of 110 tonnes.
A limited number of Ariane 5 GS are being produced and these will be launched in the coming two years. The first flight of the Ariane 5 GS version took place successfully on 11 August 2005.
