Over the past decade, China’s space program has made remarkable progress in launch vehicle development, with multiple new rockets successfully completing their maiden flights—signifying a comprehensive upgrade in the nation’s launch capabilities. In 2015, the Long March 6 and Long March 11 rockets debuted; the former is a new-generation small liquid-fueled launcher, while the latter is a solid-fueled rocket designed for rapid-response missions. In 2016, the Long March 7 successfully launched from the Wenchang Spacecraft Launch Site, serving as a medium-lift vehicle primarily for Tianzhou cargo missions to support China’s space station. The Long March 5B made its first flight in 2019, optimized for heavy payloads in low Earth orbit and becoming the primary launcher for space station modules. In 2020, the Long March 8 completed its maiden flight, filling a gap in Sun-synchronous orbit launch capacity (3–4.5 metric tons) and featuring potential reusability. Meanwhile, private aerospace companies have also emerged: in 2021, iSpace’s Hyperbola-1 became the first Chinese privately developed rocket to reach orbit, and in 2023, Landspace’s Zhuque-2 became the world’s first methane-fueled rocket (using liquid oxygen and methane) to achieve orbital insertion. These milestones have not only expanded China’s launch vehicle family but also laid a solid foundation for future deep-space exploration, commercial launches, and reusable rocket technology.
近十年来，中国航天在运载火箭领域取得了显著进展，多型新型火箭成功完成首飞，标志着中国航天发射能力的全面提升。2015年，长征六号、长征十一号相继首飞，前者是新一代小型液体燃料火箭，后者则是固体燃料快速响应运载火箭，适用于应急发射任务。2016年，长征七号在海南文昌航天发射场成功首飞，作为新一代中型运载火箭，主要用于发射天舟货运飞船，支持中国空间站建设。2019年，长征五号B遥一火箭完成首飞，专为近地轨道重型载荷设计，成为中国空间站舱段的主要运输工具。2020年，长征八号首飞成功，填补了太阳同步轨道3–4.5吨运力空白，具备可重复使用潜力。此外，民营航天企业也崭露头角：2021年，星际荣耀的双曲线一号成为首个成功入轨的中国民营液体火箭；2023年，蓝箭航天的朱雀二号成为全球首枚成功入轨的液氧甲烷火箭。这些首飞不仅拓展了中国火箭谱系，也为未来深空探测、商业发射和可重复使用技术奠定了坚实基础。
