| Summary | A two-stage medium-lift launcher originally designed with a reusable combined-booster-recovery concept in mind, though currently operational vehicles fly expendable. Exclusively from Wenchang. | 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. | ULA's next-generation medium-heavy rocket replacing Atlas V. Powered by two BE-4 engines on the first stage and a cryogenic Centaur V upper stage. NSSL-certified March 2025; first NSSL mission USSF-106 flew Aug 13, 2025. Paused by the Space Force after the USSF-87 SRB nozzle anomaly (Feb 12, 2026), with return to flight expected ~late 2026. |
