Qian Xuesen, the PRC`s aviation scientist, puts forward the"Opinions on China`s establishment of aviation defense industry. " as early as February 1956 and actively emphasized the importance of the aerospace science. Soon after, PRC has founded the 5th Research Institute to actively develop various technologies of communication, meteorology, experiments and navigation satellites... etc. In the past decades, influenced by the Persian Gulf War, PRC has dedicate itself to thoroughly consider the application of high technology warfare in future. And moreover, with the improvement of technology and upgrade of weapon equipment, PRC has constantly improved it’s type of modern warfare. Hence, to integrate the appliance of development of every domestic aerospace technology in military aspect and actively pre-act the preparation for the confrontation of happening warfare, is PRC’s expectation to seize the aerospace superiority and advantages. In recent years, from the development of Beidou navigation satellite, successful test of "Mozi" quantum satellite, successful connection of Shenzhou 11th spacecraft and Tiangong-2nd, Chang ' e-4th landed on the far side of the moon, and achievement of aerospace technology in “Zhuhai Air Show 2018”, we can deeply feel PRC’s great leap in aerospace technology and anticipate the future path of appliance of aerospace technology in military aspect. In February 2019, the Defense Intelligence Agency of U.S. Department of Defense has announced PRC has developed laser weapons with ability of attack and destroy satellites. This has indirectly pushed the U.S. to expedite it’s space force, and promoted PRC’s military capability in aerospace and research of space weapons. In consideration of confronting PRC’s aerospace technology and with appliance of military influence on regional and Taiwan Strait security, we should study PRC’s developing trend and strategic intent,and to develop our counter strategy and operation capability to deter the threat from PRC’s space force,and keep the stability of the Taiwan Strait with limited resources,and to effectively achieve the strategic goal of “Multiple deterrence, resolute defense.”
