| Summary | China's workhorse medium-lift rocket, used exclusively for Tianzhou automated cargo missions to the Tiangong space station. Designed to replace the Long March 2F for high-cadence LEO/cargo missions. Uses the same YF-100 engines as Long March 5's boosters. | Germany's first orbital-class launcher attempt; its first flight in March 2025 was Western Europe's first orbital launch attempt from the European mainland. A qualification second flight carrying CubeSats and ESA experiments has slipped repeatedly through 2026. | Relativity Space's Falcon-9-class successor to Terran 1, partially 3D-printed, with 13 Aeon R methalox engines on a reusable first stage; second stage and fairing expendable. |
