The Ariane 5 GS was derived from the Ariane-5 Generic launcher, produced after the end of the Ariane 5 G+ series.

This version integrated elements produced in the frame of the Ariane 5 ECA and Ariane 5 ES ATV developments. It incorporated:

  • 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) used the Vulcain 1B engine delivering a thrust level of 110 tonnes.
The Ariane 5 GS is no longer being used. The first flight of the Ariane 5 GS took place successfully on 11 August 2005.
