The development of homeland air defense

In the First World War, a form of localized air defense of one city and one place had already appeared. the emergence of radar in the 1930s and the use of jet fighters for air defense operations in the late stages of the Second World War contributed to the formation and development of homeland air defense centered on strongholds. After the Second World War, surface-to-air missiles were introduced into the air defense weapon system, and the degree of automation of intelligence and warning, command and control, and other systems was increased, further improving the homeland air defense system. The homeland air defense of the People's Republic of China (PRC) was gradually developed in the practice of air defense operations. 1950 saw the establishment of the People's Liberation Army (PLA) Air Defense Command (ADC), which initially set up the system of homeland air defense. 1955 saw the renaming of ADC to the Air Defense Force (ADF) Command, which unified the organization of homeland air defense. 1957 saw the merger of the ADF with the Air Force (AAF), and the unified organization and implementation of homeland air defense by the Air Force (AAF), which further developed and perfected the system of homeland air defense on a national scale. The national air defense system has been further developed and improved.
