ArianeGroup / Arianespace vs United Launch Alliance: 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.

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

Positioning

United Launch Alliance (a Boeing-Lockheed JV) is targeting 18-22 launches in 2026 (versus 6 in 2025, a chronic cadence shortfall) as it ramps its NSSL-certified Vulcan alongside remaining Atlas 5 flights, with ~6 Vulcans in storage and doubled Cape processing capacity. It is structurally sold out for years on a 26-mission NSSL slate, 38 Vulcan launches for Amazon Leo (the largest commercial launch agreement), and Starliner and ViaSat-3 missions, but squeezed between SpaceX economics and Blue Origin ambitions. The current revenue figure is dated (~$1.3-1.5B class, no filing).
