On this day, 75 years ago, on April 14, 1950 (February 28, 1950 in the lunar calendar), the Central Military Commission's Naval Leadership Organization was established. On April 14, 1950, the Central Military Commission's Naval Leadership Organization was established. Previously, in January 1949, Mao Zedong proposed at a meeting of the Political Bureau of the CPC Central Committee: We want to form a navy. In March of the same year, in a reply to the officers and soldiers of the "Chongqing" uprising, he pointed out that in addition to the army, we must also build our own air force and navy. On April 23, 1949, the first naval force of the China people-the Navy of the East China Military Region was born in the war, and Zhang Aiping was appointed commander and political commissar. Following the establishment of the Navy of the East China Military Region, in less than a year, naval forces were formed in the northern and southern coastal areas (later changed to the South China Sea Fleet, the East China Sea Fleet and the North Sea Fleet respectively). In order to provide centralized and unified leadership of the navy and carry out comprehensive construction of the navy in a planned manner, on April 14, 1950, the Navy Leadership Organization of the Central Military Commission was established in Beijing, with Xiao Jinguang as commander. From then on, the Navy officially became a service of the People's Liberation Army of China. Due to the harsh conditions at that time, there were no houses in the naval establishment. Faced with this situation, Chairman Mao Zedong said six words-"Build it yourself, and I will approve the money." After the house was built, Chairman Mao inspected it in person. Since its birth, the People's Navy has cooperated with the army, air force and militia in the battle to liberate the coastal islands of our country. The "fleet" mainly composed of dilapidated surface ships and small wood-shelled gunboats left over from the Qing Dynasty and the Kuomintang period liberated the coastal islands and demonstrated the power of the People's Navy. The US imperialists and the Chiang Kai-shek clique attempted to strangle the People's Navy in the cradle. First, they dispatched aircraft to chase and bomb ships anchored in the Yangtze River in turn. Then, mines were laid in coastal harbors such as the Yangtze River Estuary and blockades were implemented. However, the People's Navy was not strangled. They broke through the blockade and became stronger and stronger in the battle. At present, the Navy is the main service of the People's Liberation Army, with naval forces and naval aviation as the main body, responsible for maritime combat tasks. It is the main force in maritime warfare. It was established on the basis of the People's Liberation Army Army. It started in East China and then developed to South China and North China, namely the three fleets of the East China Sea, South China Sea and North China Sea. It is mainly composed of submarine forces, surface ship forces, naval aviation, naval coast defense forces, marine corps and other arms. The naval organizational sequence is the service headquarters, fleet, naval base (military level), marine police district (division level), ship detachment (division level), ship brigade (regiment level), and ship squadron (battalion level).
