Ariane 6 mock up
|Function||Medium-heavy launch vehicle|
ESA and Arianespace
|Country of origin||Europe|
|Launch sites||Guiana Space Centre|
Ariane 6 is a launch vehicle being developed by the European Space Agency to be the newest member in the Ariane launch vehicle family. ESA has finalised the preliminary design of the next generation rocket; a smaller more flexible rocket, featuring the same payload fairing diameter as the Ariane 5 ME and capable of launching a single satellite of 3 to 6.5 tonnes to a geostationary transfer orbit. The vehicle is a three stage design in which the first stage uses three identical solid rocket motors in a side-by-side configuration, the second stage will use a single identical solid rocket motor mounted above the first stage, the third stage will be a restartable liquid cryogenic Vinci engine to allow for complex and high energy orbits. The four motors of the first and second stage will each carry 135 tonnes of solid propellant and have an empty mass of 10 tonnes.
In 2012, detailed definition studies were funded. ESA will in 2014 decide on full funding, which could lead to a launch around 2021. The chairman the German Aerospace Center commented that while building Ariane 6 in one location would be much more efficient, but "then it is no longer a European launcher. It is a French or German launcher. Therefore, the discussion about industrial distribution is one of the core questions for the next launcher in Europe. It is hard stuff."
A new launch pad location in French Guiana has been selected, and completion of the Ariane 6 design in July 2013 is expected to kick off design of the launch pad. CNES is aiming to launch the Ariane 6 a minimum of eight times each year, with a goal of supporting twelve annual launches.
The target "production and operations cost" for the launch system is 70 million Euros per launch, a 30% reduction in the cost of launching an equivalent 6.5 tonne payload on the Ariane 5, although this is not necessarily the launch price at which Ariane launches will be offered to launch customers.

"12 flights annually to keep production and operations costs within the targeted 70 million euros ($95 million) per launch [and] is viewed as an all-in cost that would include about 14 million euros per launch in ground operations and also would include the sales and marketing charges incurred by Arianespace."

"Ariane 6 would fly in 2020 assuming a development go-ahead in 2014. CNES’s Ariane 6 team is operating under the “triple-seven” mantra, meaning seven years’ development, 7 metric tons of satellite payload to geostationary transfer orbit and 70 million euros in launch costs. CNES estimates that Ariane 6 would cost 4 billion euros to develop, including ESA’s customary program management fees and a 20 percent margin that ESA embeds in most of its programs."
