On November 16, the Chinese Academy of Launch Vehicle Technology (also known as the First Research Institute of China Aerospace Science and Technology Corporation, formerly known as the Fifth Academy and the First Branch of the Ministry of National Defense, hereinafter referred to as the "Rocket Academy") celebrated its 65th anniversary. Here, China's first missile was born, China's first mission of "combining two bombs" was completed, and China's first man-made earth satellite was launched, which is an important force in China's "two bombs and one satellite" cause; Here, we successfully developed a series of missile weapons, laying the cornerstone of national strategic security; We have successfully developed 12 Long March series launch vehicles, launched launch missions for major national projects, such as the manned space program, the lunar exploration program, and the Beidou program, and made outstanding contributions to the three major milestones in China's space industry. We started hard and embarked on the road of self-reliance. "The Soviet missiles arrived before the drawings. We started 'anti design' before the drawings arrived." One month before the establishment of the Rocket Academy, China and the Soviet Union signed the New Technology Agreement for National Defense. The Soviet Union will provide China with missile samples and technical data, and send experts to help China copy the "1059" missile (later renamed "Dongfeng I"). According to the wonderful memory of Chen from the Technical Strength Office of a department (now the Overall Design Department), at that time, China's industrial foundation was weak and science and technology was backward. Technicians had never learned the course on missiles. Looking at the missiles in front of them, they did not know where to start. "Anti design" is by no means easy, which seems to indicate that China's aerospace industry will take the road of self-reliance and hard struggle from the very beginning. At that time, there was no corresponding missile production, test and final assembly test workshop in the Rocket Academy, but the aerospace personnel were not afraid of difficulties and loved to study. They "dissected" the missiles bit by bit, and assigned each section for research according to its specialty. "Everyone is very enthusiastic. They take the initiative to work overtime without waiting for their superiors to assign tasks." On November 5, 1960, the "1059" was successfully launched, and China's own missile flew up on the horizon for the first time. In March 1962, the test flight of "Dongfeng II" failed, which was the first major setback for China's aerospace industry since its start of self-reliance. Wei Qiyong, the former director of Room 10 of the General Design Department, has never forgotten the feeling of heartache. Everyone has been engaged in design improvement and actively prepared for go around. Astronauts never fear setbacks. They summarize the experience and lessons of failure and propose a scientific research management system that "everything passes the overall test and everything passes the ground test". These "two things" have been passed down to this day, becoming a valuable asset of China Aerospace, and playing an important role in the development of subsequent model products. Of course, this failure has also become a turning point for China's aerospace industry to form the concept of reliability. In 1964, the modified design of "Dongfeng II" was successfully launched. Two years later, the "combination of two bombs" was a complete success, and China became the fifth country in the world to launch nuclear weapons with its own missiles. Since then, China has had nuclear missiles that can be used in actual combat, and its science and technology and national defense forces have developed rapidly. Together, the Daba Mountain, which is the first snow mountain conquered by the Red Army on the Long March, demonstrates the space responsibility of thousands of miles. In this place where the Red Army fought, we can still feel the lofty aspirations of spacemen. "We are using the hot production" General Assembly War "
