3大火箭企业，同台披露最新时间表

Core Viewpoint - The article emphasizes the critical need for reusable rockets in the domestic commercial space industry to address the significant capacity gap and cost pressures associated with satellite internet constellation construction. The year 2026 is highlighted as a pivotal year for the technological validation of reusable rockets in China [1]. Group 1: Blue Arrow Aerospace - Blue Arrow Aerospace's Zhuque-3 rocket aims for high-frequency reuse, with a three-step development plan: solidifying recovery technology, transitioning to batch production with a target of 30 launches per year, and initiating the development of Zhuque-3A alongside various recovery methods [3][4]. - The first flight of Zhuque-3 on December 3, 2025, validated numerous reusable rocket technologies despite the unsuccessful recovery of the first stage [5]. Group 2: Star River Dynamics - Star River Dynamics plans to achieve the maiden flight of the Zhishen-2 rocket by the end of 2026, utilizing a large reusable liquid rocket engine with 3D printing technology for integration and lightweight innovation [8]. - The Zhishen-1 rocket has a launch cost of approximately 60,000 yuan per kilogram for satellite customers, with the Zhishen-2 rocket having a takeoff mass of about 757 tons and a thrust of approximately 910 tons [9]. Group 3: China Aerospace Science and Technology Corporation - China Aerospace is adopting a dual-track strategy to address the current shortage of launch capacity, focusing on both large-capacity rockets and recovery technology to reduce launch costs and overcome production bottlenecks [11][12]. - The launch cost for the Lijian-2 rocket has been reduced to 30,000 yuan per kilogram, comparable to SpaceX's Falcon 9, with further reductions expected through recovery [13].
