ArianeGroup / Arianespace vs SpaceX: Heavy & medium compared

Scores, Space (of 10)

Darker bar: ahead of the other company on that measure.

Positioning

ArianeGroup (Airbus/Safran 50/50) and Arianespace operate Europe's autonomous access to space via the now-operational Ariane 6, whose first four-booster A64 flight succeeded in February 2026 carrying 32 Amazon Leo satellites, with a rising 2026 cadence. ESA's Launchers Exploitation Arrangements (November 2025) formalized their monopoly over Ariane 6 operation and commercialization, backed by 18 contracted Amazon Leo launches and the Galileo/Copernicus/IRIS2 institutional anchor, with the MaiaSpace reusable-small subsidiary flying from early 2027. The vehicle is fully expendable (no EU reusable before the 2030s); the current group revenue figure is dated.
