French orbital launch vehicle. The Ariane 5 was a completely new design, unrelated to the earlier Ariane 1 to 4. It consisted of a single-engine LOx/LH2 core stage flanked by two solid rocket boosters. Preparatory work began in 1984. Full scale development began in 1988 and cost $ 8 billion. The design was sized for the Hermes manned spaceplane, later cancelled. This resulted in the booster being a bit too large for the main commercial payload, geosynchronous communications satellites. As a result, development of an uprated version capable of launching two such satellites at a time was funded in 2000.

Status: Active. First Launch: 2016-06-18. Last Launch: 2016-10-05. Number: 2 .

Ariane 5G Initial version of the Ariane 5, a bit too large for the main commercial geosynchronous communications satellite payloads.

Ariane 5ECA French orbital launch vehicle, first version of the evolved Ariane 5. The solid booster motors propellant load was increased by 2.43 metric tons and the case was welded, for a weight saving in dry mass of 1.9 metric tons. The core was powered by an improved Vulcain 2 engine. The oxygen-rich cycle of the engine allowed the oxygen bulkhead to be moved within the stage, resulting in a 15.2 metric ton increase in propellant in the core. A new LOx/LH2 upper stage, using the HM7B engine and oxygen tank from the Ariane 4 series, replaced the storable propellant EPS stage of earlier models. The result was an increase in payload to geosynchronous transfer orbit from 6 metric tons to 10.5 metric tons.

Ariane 5Gp As Ariane 5G but with new L10 upper stage.

Ariane 5GS As Ariane 5g+ but the solid booster motors propellant load was increased by 2.43 metric tons and the case was welded, for a weight saving in dry mass of 1.9 metric tons.

Ariane 5ES Version of the evolved Ariane 5 using a version of the EPS storable propellant stage instead of the new LOx/LH2 stage. Result was a payload to GTO of 8 metric tons. 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 maneuvers. Specifically designed to orbit ESA's Automated Transfer Vehicle (ATV) resupply vehicle for the International Space Station.
