The Ariane 5 ES (Evolution Storable) has an estimated LEO launch capacity of 21,000 kg (46,000 lb). It includes all the performance improvements of Ariane 5 ECA core and boosters but replaces the ESC-A second stage with the restartable EPS used on Ariane 5 GS variants. It was used to launch the Automated Transfer Vehicle (ATV) into a 260 km circular low Earth orbit inclined at 51.6° and has been used 3 times to launch 4 Galileo navigation satellites at a time directly into their operational orbit. The Ariane 5 ES flew 8 times from 2008 to 2018 with no failures.
