This first launch of the four-booster version of Ariane 6, operated by Arianespace, took 32 satellites for Amazon’s Leo constellation to low-Earth orbit. Liftoff occurred at 13:45 local time (16:45 GMT/17:45 CET) from Europe’s Spaceport in French Guiana, with separation of the last satellites occurring after 114 minutes.

Ariane 6 in its four-booster configuration, known as Ariane 64, doubles the rocket’s performance compared to the two-booster version that has flown five times including the inaugural flight in 2024. The P120C boosters used by Ariane 6 are one of the most powerful one-piece motors in production in the world. Flying with four boosters takes Ariane 6 to a whole new class of rockets. With the extra thrust from two more boosters Ariane 6 can take around 21.6 tonnes to low Earth orbit, more than double the 10.3 tonnes it could bring to orbit with just two boosters. The launch demonstrated the performance of four boosters working together with the main stage in real flight.
