Recently, China Aerospace Science and Technology Corporation (CASC) announced the successful development of a new generation of 4-meter-class reusable launch vehicle, marking a critical step forward in China’s pursuit of low-cost, high-frequency space launches. With a diameter of approximately 4 meters, the rocket employs a liquid oxygen/kerosene propulsion system and features vertical takeoff and landing capabilities, allowing its first stage to be recovered and reused multiple times—significantly reducing launch costs. Compared to traditional expendable rockets, this new design prioritizes economic efficiency and sustainability, making it well-suited for missions such as low-to-medium Earth orbit satellite constellations, commercial launches, and rapid-response operations. According to reports, the rocket has already completed multiple ground tests and is scheduled for its maiden flight within the next two years. This advancement not only enhances China’s competitiveness in the global commercial space market but also lays the groundwork for a flexible and efficient space transportation infrastructure. As global demand for reusable rocket technology surges, China is accelerating its strategic deployment in this key area, driving its aerospace industry toward high-quality, large-scale development.
近日，中国航天科技集团宣布成功研制新一代四米级可重复使用运载火箭，标志着我国在低成本、高频次航天发射领域迈出关键一步。该火箭直径约4米，采用液氧煤油推进系统，具备垂直起降能力，核心一级可多次回收复用，大幅降低发射成本。与传统一次性火箭相比，其设计理念更注重经济性与可持续性，适用于中低轨卫星组网、商业发射及快速响应任务。据悉，该火箭已完成多项地面试验，计划在未来两年内开展首飞。此举不仅将提升我国商业航天的国际竞争力，也为构建灵活、高效的空间运输体系奠定基础。随着全球对可重复使用火箭技术需求激增，中国正加速布局这一战略高地，推动航天产业向高质量、规模化发展。
