| Summary | 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. | The larger sibling of Kuaizhou-1A, roughly 3.75x the payload class, road-mobile and solid-fueled, recovering commercial cadence after a 2020 debut failure. | 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. |
