Ariane 5 provides a family of heavy-lift launchers. New upper stages, along with
modifications to the main cryogenic stage and solid boosters, will
increase performance and meet demands of a changing market.
Ariane 5 ESC-A
This upper stage will enable Ariane 5 to place 10,000-10,500 kg.
into geostationary orbit beginning in 2004. 
Ariane 5 Versatile
This improved version of Ariane 5's current upper stage will increase the GTO payload lift capability to 7,300-8,000 kg.
Cryogenic Main Stage and Solid Boosters
The main stage's propellant tanks will be changed and a new Vulcain
engine version used, while the solid boosters' propellant load is
to be increased.
