  Ariane 64

  Ariane 64 (A64) is the heavy configuration of Ariane 6, the European expendable launch system developed for the European Space Agency and CNES, manufactured by a consortium of European companies led by ArianeGroup and operated by Arianespace as the replacement for Ariane 5. It is not a separate rocket: Ariane 6 is offered in variants distinguished by the number of solid rocket boosters strapped to the same central body, and the 64 is the one that carries four, against two on Ariane 62. The vehicle stands 63 m tall and 5.4 m in diameter, and comprises two liquid hydrogen and liquid oxygen stages: the lower module, with a single Vulcain 2.1 engine of 1,370 kN and roughly 140 tonnes of propellant, and the upper module, driven by a Vinci engine of 180 kN able to burn for up to 900 seconds and to restart up to five times. With its four P120C boosters, Ariane 64 weighs about 860,000 kg at liftoff and can place 21,650 kg into low Earth orbit, 11,500 kg into geostationary transfer orbit, 15,500 kg into Sun-synchronous orbit and 8,600 kg onto a lunar transfer trajectory. Like Ariane 5, it can launch two geosynchronous satellites together. The P120C is a solid motor shared with Europe's small launcher and an improved version of the P80 used on the original Vega; each unit holds about 142 tonnes of propellant. A later evolution, Ariane 64L Block 2, replaces those boosters with the P160C, extended by one metre to carry an additional 14 tonnes of propellant, and introduces an uprated 200 kN Vinci. The A64 launch cost was estimated at €115 million in 2018.
