Уже сделали. РД-120 называется. Но это слишком просто. "Барон любит, чтоб было потруднее".

РД-120 это отдельная тема - можно обсуждать логичная ли такая схема на фоне 1D+ - но он разве не украинский? а нам надо свой!

Ariane 6 and Vega C: concrete progress; staying on track
Technical innovations already introduced in current family

During 2017, Arianespace's current range of launchers has evolved to improve its competitiveness as from today.

Accordingly, both Ariane 5 and Vega are now being progressively fitted with new "out-of-autoclave" fairings, which will be systematically used on the new Ariane 6 and Vega C. Built by RUAG of Switzerland, these fairings are made by a simplified and more highly automated manufacturing process.

In parallel, Arianespace is continuing its Ariane 5 ECA performance improvement plan through the end of 2019, including increases in both payload weight carried and volume available under the fairing.

Finally, an overall competitiveness improvement plan will guarantee lower costs implemented on Ariane 5, even before the arrival of Ariane 6.

Gearing up for the operation of Ariane 6 and Vega C

After the French CNES space agency transferred its shares in Arianespace to Airbus Safran Launchers in December 2016, Arianespace's new governance structure took effect at the end of March 2017. Airbus Safran Launchers – which became ArianeGroup on July 1, 2017 – is now the majority shareholder in Arianespace, with 74% of its share capital. The rest of Arianespace's European shareholding remains unchanged.

Arianespace also is gearing up for the operation of Ariane 6 and Vega C, decided in conjunction with ESA, CNES in France, ArianeGroup and Avio. The partners are setting up a structure with greater integration of the different teams at the Guiana Space Center to boost competitiveness.

As a result, during the launch campaign for Vega's Flight VV10 mission – Avio, as industrial prime contractor for Vega – for the first time took responsibility for preparing the launcher until its liftoff (H0), while Arianespace maintains full responsibility for customer relations, as well as operations for the final countdown and the launch decision.

A similar change will be applied to Ariane 5 operations as soon as 2018.

Ariane 6 and Vega C: on schedule, with Arianespace customers at the heart of the process

The development of Ariane 6, with ArianeGroup as industrial prime contractor, is based on regular "Maturity Gates," with a first Ariane 6 launch planned for July 16, 2020, followed by a full capacity of 11 to 12 launches per year from 2023.

Arianespace is actively preparing the transition between its current launchers and Ariane 6 and Vega C. A key milestone on the operational and financial issues of the transition (2020-2023) will be held at the end of 2017 under the auspices of ESA. The conclusions will be presented to the ESA Council in March 2018. It is in this context that the European institutions will confirm their policy of grouped purchases of the Ariane 6 and Vega C launchers (with the first flight of Vega C scheduled for 2019).

Additionally, discussions are intensifying with commercial operators and institutional customers for the purchase of these future launchers – as already demonstrated by the first contract for Vega C and the first possible option for Ariane 6.

More than ever, Ariane 6 and Vega C are materializing – with the support of Arianespace customers – as Europe's response to the evolving space adventure, providing a source of new opportunities.

First Ariane 6 contract: Arianespace to orbit four Galileo satellites on two Ariane 62 launches

Arianespace will launch four new satellites for the Galileo constellation, using two Ariane 62 versions of the next-generation Ariane 6 rocket from the Guiana Space Center in French Guiana.

The contract will be conducted by the European Space Agency (ESA) on behalf of the European Commission (DG Growth) and the European Union.

Stéphane Israël, Arianespace Chief Executive Officer, and Paul Verhoef, Director of Navigation at the European Space Agency (ESA), signed the launch contract for four new satellites to join the European satellite navigation system Galileo. The contract will be conducted by ESA on behalf of the European Commission (DG Growth).

These launches are planned between the end of 2020 and mid-2021, using two Ariane 62 launchers – the configuration of Europe's new-generation launch vehicle that is best suited for the targeted orbit. The contract also provides for the possibility of using the Soyuz launch vehicle from the Guiana Space Center, if needed.

Both missions will carry a pair of Galileo spacecraft to continue the constellation deployment for Europe's satellite-based navigation system. The satellites, each weighing approximately 750 kg., will be placed in medium earth orbit (MEO) at an altitude of 23,222 kilometers and be part of the Galileo satellite navigation constellation.

Galileo is the first joint infrastructure financed by the European Union, which also will be the owner. The Galileo system incorporates innovative technologies developed in Europe for the greater benefit of citizens worldwide.

A total of 18 Galileo satellites already are in orbit. Fourteen of these satellites were launched two at a time by Soyuz launchers, with the last four orbited on a single Ariane 5 ES mission in November 2016. Two more Ariane 5 ES missions are planned on December 12, 2017 and in the summer of 2018.

Following the signature of this latest contract, Stéphane Israël, CEO of Arianespace, said: "Arianespace is especially proud to have won this first launch contract for the Ariane 6 from its loyal customers and partners, the European Commission (DG Growth) and ESA. We are very pleased to have earned this expression of trust from the European Commission; by choosing to continue the deployment of the Galileo constellation with two Ariane 62 launches, they become the first confirmed customer for our next-generation heavy launcher, which is slated to make its initial flight in the summer of 2020. Through this decision, which adds two additional launches to follow the already-scheduled Ariane 5 ES flights, the European Commission and ESA are clearly indicating a key commitment to Arianespace's next generation of launchers, which reaffirms more than ever its mission to ensure Europe's autonomous access to space."

Получается 2 ускорителя стоят 45 млн, 4 ускорителя 90 млн, все кроме ускорителей 40 млн. Что-то здесь не так.  :)

Версии отличаются не только ускорителями. Тут нужна стоимость ГО и Sylda.

У них разные обтекатели?

Я так понимаю гидразиновой ступени больше не будет?

Ariane 62 по энергетическим возможностям примерно равнозначна Протону Среднему и Союзу-5 с Байконура.

Inert Propellant Casting Loading of the first full scale P120C SRM completed



18 September 2017 – Regulus, an Avio/ArianeGroup joint venture, has completed the loading with inert propellant of the first Booster Case of the new P120C Solid Rocket Motor in French Guyana. Regulus is in charge of solid propellant manufacturing and casting for Vega and Ariane Launch Vehicles.
Спойлер
About 142 Tons of inert propellant have been produced and cast in the Booster Case, that was shipped this summer from Avio premises in Italy, to demonstrate and validate new manufacturing equipment, machines and process.

It represents the largest single casting of a solid propellant motor ever done.
Propellant curing is current on-going and, after cooling and casting tooling removal, the Loaded Case will be submitted to an intensive set of tests and checks (RX inspection, propellant mechanical test).

This represents an important milestone to free the way to the casting of the active propellant of the first P120C SRM, devoted to the first static firing test foreseen in the first half of 2018.
The P120C is the new first stage motor common to the new generation European launchers Ariane 6 and Vega C and it is jointly developed by Avio and the Ariane Group under their joint venture Europropulsion.
