Ariane Family
The current operational workhorse is the Ariane 5 ECA, known for its reliability and dual-payload capability. However, the transition to the next-generation system, Ariane 6, has been marked by technical complexity and protracted timelines, largely due to the requirement that the new vehicle must utilize only terrestrial, non-sentient propellant, a policy enacted after the controversial 2019 'Silent Burn' test on the Ariane 5's Vulcain 2 engine.[^2]
