“Project Nantianmen” Is Becoming RealityOriginally featured in the Chinese sci-fi film *The Wandering Earth 2*, “Project Nantianmen” envisions an integrated aerospace defense and space development system. It aims to establish large orbital stations, aerospace fighters, and extraterrestrial bases to enable sustained human presence and control in near-Earth and deep space.In recent years, China’s rapid advancements in aerospace have brought this once-fictional concept closer to reality. In 2023, China successfully launched the Mengzhou crewed spacecraft and unveiled a prototype of the Haolong reusable spaceplane—key components of a next-generation Earth-to-orbit transportation system. Meanwhile, the Tiangong Space Station now supports long-term human habitation and hosts extensive scientific experiments.China is also making progress in reusable launch vehicles, aerospace plane technologies, and lunar research station planning—all aligning closely with the core ideas of Project Nantianmen. Notably, the Aviation Industry Corporation of China (AVIC) previously showcased futuristic aerospace concepts under the “Nantianmen” banner, including stealth aerospace fighters and orbital strike platforms. Though conceptual, these designs reflect China’s strategic vision for integrated air-and-space operations.What began as science fiction is now evolving into national strategy—demonstrating China’s ambition, innovation, and growing capability to explore and harness the vast expanse of space.
“南天门计划”正照进现实“南天门计划”最初源自中国科幻作品《流浪地球2》，是一个构想中的空天防御与太空开发体系，旨在通过建设大型轨道空间站、空天战机和地外基地，实现人类对近地空间乃至深空的常态化控制。近年来，随着中国航天事业的迅猛发展，这一科幻构想正逐步走向现实。2023年，中国成功发射“梦舟”载人飞船和“昊龙”货运航天飞机模型，标志着新一代天地往返运输系统进入工程实施阶段。与此同时，中国空间站“天宫”已实现长期有人驻留，并开展大量科学实验和技术验证。此外，中国还在推进可重复使用航天器、空天飞机关键技术攻关以及月球科研站建设，这些都与“南天门计划”的核心理念高度契合。更值得注意的是，中国航空工业集团曾以“南天门计划”为名发布一系列未来航空装备概念图，包括隐身空天战斗机、轨道轰炸机等，虽属创意展示，却反映出国家在空天一体化战略上的前瞻布局。从科幻设想到国家战略，“南天门计划”不仅体现了中国人对星辰大海的向往，也彰显了中国在空天领域自主创新、逐梦深空的决心与能力。
