Ariane 6

Amazon Leo LE-01 was a mission success using the first Ariane 64 configuration.

The inaugural Ariane 64 commercial flight carried Amazon’s Kuiper (Leo) constellation and brought the constellation to over 200 operational spacecraft.

Both the Ariane 64 and United Launch Alliance’s Vulcan rockets completed recent launches successfully.

The Ariane 64 configuration is intended for multi-payload missions and large satellite constellations.

The four-booster configuration of Ariane 6 is designated Ariane 64.

Arianespace expects the Ariane 6 Ariane 64 configuration to support a sustained launch cadence for constellation deployment.

Ariane 64 doubles the rocket's performance compared with the two-booster version of Ariane 6, which has flown five times including the inaugural flight in 2024.

The European Space Agency manages development of the Ariane 6 launcher and coordinates an industrial network across 13 European nations.

ESA's operational rocket fleet includes Vega-C, Ariane 62, and Ariane 64, enabling transport of small and large payloads to near and distant orbits.

Ariane 64 is the four-booster variant of Ariane 6 designed to provide greater payload capacity than the two-booster configuration.

The Ariane 64 first flight carried 32 satellites for the Amazon LEO constellation formerly known as Project Kuiper.

The Ariane 64 is a four-booster, enhanced version of the Ariane 6 rocket.

Arianespace’s 2026 flight plans include the first flight of the upgraded Block II Ariane 64 variant featuring the more powerful P160C boosters.

The Ariane 64 four-booster variant is capable of delivering payloads of over 21 tonnes to low Earth orbit.

Arianespace launched the first Ariane 64 four-booster variant from the Guiana Space Centre on 12 February.

Mission VA267 used an Ariane 6 launch vehicle in the Ariane 64 configuration.

A third and final upper-stage burn 160 minutes after liftoff is planned to place the Ariane 64 upper stage into a destructive orbit so the stage will burn up in Earth's atmosphere.

Arianespace’s VA267 mission launched on February 12, 2026 using the Ariane 64 configuration of Ariane 6.
