Version of the evolved Ariane 5 using a version of the EPS storable propellant stage instead of a new Lox/LH2 stage. Result is a payload to GTO of 8 tonnes. The use of the new Aestus restartable engine in the upper stage fitted the vehicle for space station logistics missions or launch of space probes requiring complex orbital maneouvres.
