| Summary | 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. | Primary launch vehicle for Cygnus ISS cargo missions from 2013–2023. Its Ukrainian-built Zenit-derived first stage and Russian RD-181 engines became untenable after the 2022 invasion of Ukraine. Northrop switched NG-20 onward to Falcon 9 while Antares 330 (with Firefly Miranda engines) is in development. | Rocket Lab's medium-lift reusable rocket targeting the $100B constellation replenishment market. Uses a 'hungry hippo' fairings design that opens at the top rather than traditional clamshell separation. First flight delayed to Q4 2026 after a Jan 2026 propellant tank test anomaly. |
