In the deep autumn of the South China Sea, with blue waves surging, a new type of submarine from the Southern Theater Command Navy quietly and stealthily cruised. Under the deep sea, in the submarine's cabin, a navigation damage management training was intensively carried out, involving multiple dangerous situations, multiple contingency plans, and multiple job positions. In the command cabin, the commander carefully assessed the situation, decisively issued orders, sealed the cabin, sealed the leak, drained the water, and extinguished the fire... The officers and soldiers at all positions responded to the orders and cooperated closely, and the "danger" was quickly successfully resolved. Sneak along the way, train along the way, and improve along the way. For the crew of the boat, such high-intensity practical training is performed almost every day during the long voyage mission. The task has come to an end. By bending my fingers, it has been dozens of days since the mission to go out to sea. During the rest period, the tense atmosphere eased and the officers and soldiers began to have time to relax. The "Dragon Palace" barber shop in the corner of the submarine reopened, and the air conditioning technician and barber Lao Jiang of the submarine became busy again. The task is important, there's no need to worry about personal image! ”Looking at the messy hair of several comrades, Old Jiang smiled and said. Talking to the author about his experience of serving his comrades over the years, Old Jiang deeply felt it. More than 20 years ago, Lao Jiang had just joined the crew as a new recruit. I remember at that time, due to factors such as mission requirements and equipment performance, submarines mostly went out early and returned late to carry out missions, and the time was not long, "said Lao Jiang. The crew spent most of their time training and learning on shore. At that time, there was a hair salon in the camp that could basically meet the needs of officers and soldiers. Later on, the intensity and level of military training and preparation gradually increased, and the degree of practical combat also became higher and higher. Once, the crew embarked on their first long voyage mission, which lasted for several weeks. After returning home, when the superiors conducted research on the execution of the mission, some crew members reported that "long-term outings on missions make life on the boat relatively monotonous, with long and messy hair that affects military appearance and mood"... The demands of his comrades touched Old Jiang. Thinking that he had learned hairdressing for a while before joining the army, he decided to purchase hairdressing supplies at his own expense and serve everyone in the camp. When there were long-distance missions, he would pack the hairdressing tools in his backpack and bring them to the boat. In this way, the barber shop became a "amphibious" barber shop that spent half of its time on land and half on boats. This situation has been going on for many years and is starting to change again. In recent years, with the deepening of the reform and strengthening of the military in the new era, submarine equipment has accelerated iteration and upgrading, and practical training has reached a new level, "said Lao Jiang. Now, the exploration of the sea by the military is getting farther and farther, and the execution of tasks is becoming more frequent. High intensity, long-term, and long-distance training has become the norm, and officers and soldiers spend more time at sea than on land. So he simply stopped the onshore barber shop and focused on managing the "Dragon Palace" barber shop. The sun and moon shuttle like a shuttle, and the times change. The "Dragon Palace" hair salon is like a window, experiencing and witnessing many scenes of military training and preparedness. During that mission, the water surface was calm and the officer in charge of sonar, Old Chen, planned to take advantage of the situation. At the beginning of the haircut, the buzzer suddenly sounded a "battle alarm", and a simulated attack and defense training immediately began. Unable to untie the siege in time, Old Chen got up and rushed to the battlefield. The battle was intense, and after several changes in attack and defense, the crew finally secured the victory after several hours. After the "enemy" situation was resolved, Old Jiang awkwardly approached Old Chen and said, "Why don't you shave your head?" It turned out that at that time, because Old Chen was too anxious to get up, Old Jiang shaved a groove on his head. After being on the boat for a long time, the functions of the "Dragon Palace" hair salon have gradually expanded. That time, the crew team collaborated with surface vessels and anti submarine forces to launch a "back-to-back" confrontation. Everyone practices offense and defense against each other, studying practical and effective winning techniques. In the joint training, the crew team conducted blockade and anti blockade exercises with a certain surface vessel unit. In order to closely meet the requirements of actual combat, everyone only agreed on the approximate task sea area in advance, without any contingency plan throughout the entire process. They independently detected targets, judged the situation, and made decisions on their own actions. As soon as the training ended, the opposing commander boarded the submarine with a pile of data, and both sides sat together around the nautical chart to review - finding each other's "shortcomings" from their respective detection data and filling their own "loopholes" in the collision of tactical ideas. During the break, the commander of the sister unit saw Old Jiang cutting his comrade's hair and realized that he should also cut his own hair. Lao Jiang immediately sent out an invitation, and a few people lined up in the submarine aisle to get their hair cut. Everyone continued to discuss parameters and insights while queuing up, creating a lively and enthusiastic atmosphere for communication. Someone joked, 'This trip was not in vain! Not only did it bring back ideas for improving combat methods, but it also gave me an experience of' washing, cutting, and blowing 'underwater!' In recent years, the training of officers and soldiers has become a common sight at the 'Dragon Palace' barber shop. Wrapping soundproof cotton on stairs can reduce walking noise, cables outside the cabin are prone to leakage, so it is important to monitor them carefully, and any potential faults must be detected as early as possible. While cutting hair, everyone exchanged tips on equipment maintenance, hidden control techniques, and troubleshooting. Here, the hair has become shorter and the confidence for diving into the deep sea has increased. The officers and soldiers said that the submarine equipment has been upgraded step by step from "eagerly awaiting" to "constantly upgrading", and the sailing time has changed from "early departure and late return" to "deep-sea voyage". The training level is getting higher and the ability to win battles is constantly improving. The small "Dragon Palace" hair salon witnessed these vivid scenes. As night fell, the submarine untied its cables and set sail again, heading towards unfamiliar waters. Old Jiang and his comrades once again embarked on a journey of sharpening their swords.
