The P120C boosters of the second Ariane 6 to launch were transported from the booster storage building to the launch pad at Europe’s Spaceport in French Guiana, on 13 January 2025.
The P120C is 13.5 m long and 3.4 m in diameter, contains 142 tonnes of solid propellant and provides a maximum thrust of 4615 kN (in vacuum) over a burn time of about 135 s. It is the largest-ever solid rocket motor built in one piece. For the next launch, two P120Cs will be strapped onto Ariane 6 as boosters for liftoff.
Ariane 6 is Europe’s newest heavy-lift rocket, designed to provide great power and flexibility at a lower cost than its predecessors. The rocket provides Europe with greater efficiency and an ensures access to space for the benefits of humankind, allowing for all types of missions from exploration to navigation, science and communications.
