The missile destroyer Kaifeng Ship, missile frigate Daqing Ship, comprehensive supply ship Kekexilihu Ship, and comprehensive submarine rescue ship Hongze Lake are located at Pier 3 in Qingdao, and full flags are hung for citizens to visit. In April 1949, the People's Navy set sail from Baima Temple in Taizhou, Jiangsu. The small sampan boats from that time gradually developed into today's graceful giant ships. April 23rd is the anniversary of the founding of the People's Navy, and also an important day for people to pay attention to the ocean, love our coastal areas, and receive national defense education. Practice is enough to defeat the enemy. Standing on the rear deck of the Anyang ship, torpedo soldier Li Yang raised his telescope. In the camera, that is Taiwan, the treasure island of our motherland. From a distance, you can see the central mountain range on the island, with overlapping peaks and clear coastline. In August 2022, the People's Navy conducted joint sea and air exercises around Taiwan Island for the first time, demonstrating to the world that our military is fully determined, capable, and capable of safeguarding national unity, sovereignty, and territorial integrity. Since the 18th National Congress of the Communist Party of China, the naval forces have focused on practical combat training, built and improved a new type of military training system, comprehensively improved the level of practical training, accelerated the transformation from coastal defense to deep-sea defense, and steadily improved their strategic deterrence and counterattack, maritime mobile operations, maritime joint operations, comprehensive defense operations, and comprehensive support capabilities. Being able to defeat battles and calmly respond to threats from the sea is the confidence and strength of the Chinese navy. In the early morning of that day, the 372 submarine carrying out the combat readiness long-range mission encountered a major danger of "underwater cliff" and rapidly descended. At a critical moment, three Dang Geng soldiers relied on their skilled skills to close more than 40 valves and shut down 14 types of electrical equipment in less than 2 minutes. The entire fleet of officers and soldiers executed over 30 commands and completed over 500 actions within 3 minutes, successfully managing the submarine to escape danger, creating a miracle in the history of submarines in China and even the world. If it weren't for daily trials and tribulations, there wouldn't have been a moment of crisis when there was no chaos to turn the tide. The naval forces have always insisted on making preparations for war as their top priority, keeping a close eye on technological changes, war changes, and adversarial changes, vigorously promoting the coupling of warfare and training, systematic training, and technological training, accelerating the transformation and upgrading of military training, and comprehensively improving maritime deterrence and practical combat capabilities. Nowadays, in the vast sea area of our motherland, the People's Navy's warships and fighter jets are constantly patrolling and guarding day and night, practicing tactics and attacking and defending in frontline confrontations and strong winds and waves. The training of People's Navy vessels on the island chain has become the norm, and the systematic training of aircraft carrier formations continues to be promoted. Navy aircraft regularly hone into the ocean. If you want to face the enemy and achieve success, it is advisable to practice it leisurely. In the early spring of this year, the first amphibious assault ship independently developed by China, Hainan Ship, went with the formation to the South China Sea, the Western Pacific and other waters, and successfully completed the task of joint training at sea. In early April, the Shandong carrier fleet went to the Western Pacific for practical exercises. The carrier aircraft took off and landed multiple times to carry out ship aircraft coordination and sea assault, calmly responding to external military aircraft disturbance and provocation. Preparing for war is always the core function and main responsibility of the People's Army. What kind of effectiveness can we play in the missile destroyer Haikou ship's system of operations
