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

Mitsubishi Heavy Industries develops and operates the H3 launch vehicle and sells launch services to government and commercial customers, including ispace.
Darker bar: ahead of the other company on that measure.
Mitsubishi Heavy Industries' H3 is Japan's flagship heavy launcher, jointly developed with JAXA and operated as MHI's launch-service business. It completed successful H3 launches carrying HTV-X1 on Oct-25, QZS-6 on Feb-25, the low-cost Type 30 configuration with six small satellites on Jun-26, and QZS-7 on Aug-26, while also signing a 2028 launch contract with ispace for the ULTRA lunar lander on Jul-26. The program is structurally important for Japan's sovereign launch, defense, navigation, ISS-logistics, and emerging commercial lunar ecosystem, but its cadence and commercial economics remain less proven than SpaceX's.
