Back to Ariane 6

ARIANE 62 IN-DEPTH

Ariane 6 was designed to be versatile, modular and competitive, leveraging:

  • State-of-the-art technologues and cutting-edge expertise from European industry
  • Production costs that are 40-50% lower than those for its Ariane 5 predecessor
  • Implementation of new industrial processes and innovative manufacturing technologies (3D printing, friction-stir welding, laser surface treatment, etc.)

The Vulcain 2.1 engine is part of the Lower Liquid propulsion Module (LLPM) and provide the thrust. This cryogenic engine offers a thrust of 135 tons in the vacuum during the first eight minutes of the flight. The Vulcain 2.1 engine is derived from the original Ariane 5 launcher’s Vulcain 2 engine.
