Watch live: first launch of Ariane 6 with four boosters10/02/2026
(...) Ariane 6 in its four-booster configuration 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 flight will demonstrate and prove the performance of four boosters working together with the main stage in flight.
For this flight, Ariane 6 will be using the long fairing that houses the 32 Amazon Leo satellites inside and protects them from the elements until they reach space. The fairing is 20 m tall and 5.4 m diameter and could carry four giraffes standing on each other’s shoulders.
As this is the first flight with a long fairing, it makes this launch the tallest Ariane 6 so far. Once assembled on the launch pad at Europe’s Spaceport in French Guiana it will be 62-m high, roughly the same as a 20-storey building. (...)
