| Summary | 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. | China's most powerful operational rocket and the backbone of its flagship space programs. Launched Tianwen-1 to Mars, Chang'e 5 sample return, Chang'e 6 far-side sample return, all Tiangong core and lab modules, and the Xuntian space telescope. The CZ-5B variant delivers entire station modules in a single flight. |
