Ariane 6 is a European expendable launch vehicle developed for the European Space Agency (ESA) and French space agency CNES, and operated commercially by Arianespace. It is the successor to Ariane 5 and is designed in two main versions, Ariane 62 and Ariane 64, to provide Europe with autonomous access to space.

Development

ESA selected the Ariane 6 design in 2014 as the next-generation Ariane launcher. The programme was created to maintain Europe’s independent access to space and to replace Ariane 5.

Design and variants

Ariane 6 is a two-stage launcher with solid boosters and a cryogenic core and upper stage. ESA identifies two versions, Ariane 62 and Ariane 64, which differ mainly in booster count and payload capacity.

Operations

Arianespace markets and operates Ariane 6, while ArianeGroup is the prime industrial contractor. The launcher is intended for institutional and commercial missions across a range of orbits.

Launch history

Ariane 6 first flew successfully on 9 July 2024. ESA later reported its second flight and first commercial mission on 6 March 2025, demonstrating the vehicle’s operational role.

Key facts

  • Ariane 6 is Europe’s latest Ariane-series launcher and is intended to replace Ariane 5.
  • The rocket has two main configurations: Ariane 62 with two boosters and Ariane 64 with four boosters.
  • ESA describes Ariane 6 as a modular launcher with a restartable upper stage for flexible mission profiles.
  • Ariane 6 uses liquid hydrogen and liquid oxygen in its cryogenic core and upper stage.
  • Its maiden flight took place on 9 July 2024 from Europe’s Spaceport in French Guiana.
