海南商业航天发射场二期主体建设过半

Core Viewpoint - The innovation power of China's commercial aerospace is continuously gathering, extending from the aerospace industry chain to key technology breakthroughs, with all technological and industrial achievements being validated at the country's commercial launch sites [1]. Group 1: Launch Site Construction - The construction of the 3rd and 4th launch pads in the second phase of the launch site is currently the main project, with over half of the construction completed [2]. - The lightning protection towers for the new launch pads have reached a height of 20 meters, and the number of towers has been reduced from four to three, making the design more economical while maintaining functionality [2]. - The important protective facility, the drainage channel, is taking shape, forming a vertical angle with the vertical foundation pit [4]. Group 2: Water Tower and Facilities - A significant facility, the water tower, is being constructed between the 3rd and 4th launch pads, combining two towers into one to save costs and shorten construction time [6]. - The dual launch pad construction is over half complete, with equipment installation and debugging expected to begin after the Spring Festival [8]. Group 3: Strategic Location and Transportation - The launch site is located in Wenchang, Hainan, at a latitude of 19 degrees north, allowing rockets to utilize the Earth's rotation for increased initial speed [9]. - The proximity of the two launch pads to the sea facilitates maritime transport, reducing transportation costs for materials and enhancing launch capacity [12]. Group 4: Recovery System and Future Development - The company is actively exploring a maritime recovery system for rockets, which includes one command and control ship and two recovery ships, enhancing recovery efficiency and protecting the landing area [12]. - The second phase of the project aims to create an industrial cluster through "integration of production and city," covering the entire process from rocket testing to launch command, with over half of the progress completed [14]. - Hainan has identified commercial aerospace as one of its three future industries, implementing multiple policies to support the development of a comprehensive industrial chain and a trillion-yuan industry cluster [16].
