ESA Signs Contracts for the Development of Ariane 6 and Vega C Launch Vehicles

The European Space Agency (ESA) on Wednesday, Aug. 12, signed contracts for the development of its two new launch vehicles. Under the first contract, worth 2.4 billion euros, the French company Airbus Safran Launchers (ASL) will build Ariane 6 launcher in its two versions, Ariane 62 and 64. The second agreement sees ELV, a joint public-private company of AVIO Group and the Italian Space Agency (ASI), under a 395 million euro deal to develop the Vega Consolidated (Vega C) booster, a modification of the current Vega launcher.

“These contracts will allow the development of a family of European launchers, highly competitive in the world market and ensuring autonomous access to space at fully competitive prices for ESA’s Member States,” said Jan Woerner, Director General of ESA.

The contracts were signed by Gaele Winters, ESA’s Director of Launchers; Jean-Yves Le Gall, President of CNES; Alain Charmeau, CEO/President of ASL; and Pierluigi Pirrelli, CEO of ELV.

During a contract signing ceremony in Paris, France, ESA also tapped the French Space Agency (CNES) to build a new launch site for the Arian 6 rocket at Europe’s Spaceport located in Kourou, French Guiana. 

The three contracts follow the decision taken at the ESA Council meeting at Ministerial level held in Luxemburg in December 2014 to maintain Europe’s leadership in the fast-changing commercial launch service market while responding to the needs of European institutional missions.

Ariane 6 contract includes, notably, a firm commitment of some 680 million euros for initial development activities (phases A & B) up to the Preliminary Design Review scheduled for mid-2016.

“Both our and our European industrial partners’ commitment is a sign of our determination to provide our customers, whether they be institutional or commercial, with a launcher that is as reliable as ever while being increasingly competitive and adapted to the rapidly evolving space market,” said Alain Charmeau, CEO of Airbus Safran Launchers. “I would once again like to thank the European Space Agency and the national agencies, in particular the CNES, the DLR [German Aerospace Center] and ASI, for their support and trust.”

Ariane 62, with two P120 solid boosters, will weigh around 500 tons at liftoff and is intended mainly for government and scientific missions. It will be capable of launching up to 5 tons into geostationary transfer orbit (GTO).

Ariane 64, with four P120 boosters, will have a liftoff weight of around 800 tons and is intended for commercial dual-satellite launches of up to 10.5 tons into GTO.

ASL teams will now finalize the design of the two versions of the Ariane 6 launcher and the accompanying industrialization process as part of a new industrial structure established within Europe to improve efficiency. The first flight of the Ariane 6 rocket is scheduled for 2020.

The main objective of the ELV contract is the development of the advanced version of Vega, denoted as Vega C, and designed to further improve the market position of the transport services of small satellites in low orbit.

The rocket aims to increase the load capacity of the orbital launcher up to 50 percent. Together with a further increase in operational flexibility, while maintaining its unrivalled orbital precision, it is expected to expand the capability to transport in the same flight a larger number of small satellites, in different orbital planes, or larger satellites. The first launch of Vega C is planned for late 2018.

"The signature of this contract is a great satisfaction and secures a new development to Vega just after signing the first production contract for the current version. The first ten Vega flights, already fully booked, confirm the response of the market. We have just celebrated the success of the second flight of the year and we settle for the third launch of 2015,” said Pierluigi Pirrelli, Chief Executive Officer of ELV.

The “C” version differs from Vega by using P120 as first rocket stage instead of P80.

ASL and ELV are working closely together on the P120C solid-propellant motor that will form Vega C’s first stage and Ariane’s strap-on boosters. P120C, entirely made with carbon fiber, will be developed by Europropulsion (AVIO-ASL joint venture). The new motor will inherit and exceed in size and complexity all the technological successes already achieved by AVIO in the development of the P80.
