At 4 o'clock in the morning in the South China Sea, the 10000 ton destroyer Xianyang split through the dark waves and raced forward. In the combat command room, officer Zhao Qiang's gaze was tightly fixed on several radar screens flashing with faint blue fluorescence. There was no sound of gunfire or waves here, except for the low hum of equipment running, and the cabin was quiet. As Zhao Qiang lightly tapped his fingertips, the dots of light on the screen jumped and connected together, accurately capturing every target in the surrounding area. This is Zhao Qiang's battlefield and also the "sharp eye" of this new type of warship. Over the past 1000 days and nights, Zhao Qiang has grown together with the Xianyang ship here, heading towards the deep blue. The encounter with the Xianyang ship began in 2021, and Zhao Qiang still remembers that when he first met, this domestically produced 10000 ton destroyer was completely different from the escort ship he had previously been on, the Yueyang ship. The highly integrated integrated mast and huge phased array radar matrix have greatly improved the detection range and accuracy, which deeply impressed Zhao Qiang. With excellent professional competence and rich experience, Zhao Qiang was appointed as the department head of the Xianyang ship. However, at the beginning of the installation, he still felt a strong sense of skill panic. In Zhao Qiang's memory, those days were a "pioneering" time, with technical data piled up like mountains and complex system integration and debugging. Relying solely on personal research is no longer sufficient to fully master this new type of ship. This time, he led the team to start learning and accumulating data from scratch. During the takeover of the ship, Zhao Qiang specially invited experts from the manufacturer and the institute to give detailed explanations to the team, and requested that department officers and soldiers set up cameras to record every step and key node in the teaching process. In practical operation, when encountering areas that were not understood, he would lead everyone to repeatedly compare the videos until they all learned and understood. The trial voyage is the most intense stage, and Zhao Qiang led the backbone team to follow up throughout the process. This is not only to familiarize oneself with the process, but also to obtain first-hand and complete experimental data. Later, department soldier Zhang Tiancheng recalled that during that time, it was normal for training uniforms to be repeatedly soaked in sweat, and "the experimental data in the late night was his best companion". After the experiment, Zhao Qiang was not satisfied with the factory's summary report. He also leads the backbone of the department to directly spread massive data on the desktop, analyze and compare it bit by bit, and sometimes even engage in heated debates. In the end, they wrote a more practical experimental summary report with guiding significance. A solid foundation in our profession will give us more confidence in the face of unexpected situations in the future. ”This is a sentence that Zhao Qiang often says to the officers and soldiers of the department. The fact proves that Zhao Qiang and his comrades' diligent study has indeed withstood the test of practical combat. That year, the Xianyang ship participated in full training at the naval training center and competed with three other new types of ships that participated in the training and assessment at the same time. In the most critical professional competition segment, facing the challenges of multi-target recognition and stable tracking in complex electromagnetic environments, Zhao Qiang led his department's officers and soldiers to perform their duties with solid skills and tacit cooperation, calmly operate, accurately and efficiently identify target attributes, and ultimately win the first place. It is also because of his outstanding contributions in this installation and full training that Zhao Qiang was awarded the third class merit. Touching the brand new military merit badge on his chest and looking at the confident faces of his comrades in the department, he felt a sense of "accumulated joy". Over the years, with the Xianyang ship's repeated sea exercises, Zhao Qiang's professional competence has become increasingly solid through practical training. But he always felt that having strong personal abilities and qualities was not enough, and it was important to make the overall quality of the department strong. This experience stems from a live combat training mission. At that time, the Xianyang ship excellently completed the planned topic exercise and began to return. No one expected that the formation command post would increase electromagnetic interference special situations on the spot. Suddenly, on the radar display screen of the Xianyang ship, a clear target light spot appeared to flicker abnormally. Subsequently, the trajectories of several key targets became intermittent and blurry. The atmosphere in the combat room suddenly became tense, which was not a part of the exercise plan. Radar soldier Li Chunhang quickly switched to anti-interference mode, but the effect was not satisfactory. At this point, the officers and soldiers instinctively looked at Zhao Qiang, waiting for him to give instructions. The approximate direction of the interference source, the pattern of signal jumps, which frequency band mainly affects us? ”Although Zhao Qiang had a solution in mind, he did not immediately issue specific operational orders. Instead, he raised a series of questions and gradually guided Li Chunhang to conduct his own analysis and judgment. In the end, Li Chunhang seized a fleeting signal stabilization gap and successfully established stable tracking. Although the handling was successful this time, Zhao Qiang felt uneasy due to Li Chunhang's hesitation and relatively mechanical operation during the response process. During the review and communication, he pointed out that the core of the problem lies in the lack of in-depth research on basic theories, which inevitably leads to officers and soldiers being accustomed to recalling "how the factory master taught them back then" when faced with "exceeding the scope" problems, making it difficult to quickly trace back to the root of the problem and conduct independent analysis and flexible response. The ultimate performance of equipment can often be forced out in the most complex and extreme environments. Merely being satisfied with 'being able to operate' and 'being able to complete tasks' is far from enough, which does not match the mission of the 10000 ton heavy drive as a' national treasure '. ”Zhao Qiang explained. This experience made Zhao Qiang determined to strictly control the learning and training of the department. Soon he launched a "theoretical deepening" campaign within the department, guiding officers and soldiers to deepen their research on equipment basic theory. During the weekly battle position training, Zhao Qiang would have different levels of veteran soldiers and volunteer soldiers who enjoy studying come up to the podium and share their personal thoughts on equipment theory. In order to explain clearly on stage, officers and soldiers must first learn and ponder on their own, and think about how to express themselves in layman's terms. At first, everyone expressed 'immense pressure', but over time, this' output forcing input 'model has instead sparked unprecedented learning enthusiasm among the department's officers and soldiers. The audience speaks with dedication, while the audience asks sharp questions. Abstract theories become vivid through the combination of practical equipment operation. Once, Sergeant Deng Wenqiang made a model out of cardboard in order to explain the principle of a certain radar clearly. The vivid explanation and demonstration made everyone suddenly enlightened. When it comes to the drill, Zhao Qiang will lead the backbone to standardize and sort out all the abnormal situations and special cases encountered, forming a learning database. Each case in the library includes phenomenon replay, disposal review, and the most important principle mining. It will also continuously optimize disposal methods and update them in various training tasks. This learning mode that closely follows actual combat has allowed the officers and soldiers of the department to accumulate a lot of experience and become more confident in their subsequent tasks. Not long ago, the Xianyang ship was carrying out a combat readiness mission. In extremely harsh sea and weather conditions, soldier Zhu Xiaolong flexibly switched radar search modes and quickly discovered and identified multiple batches of airborne targets. No matter how advanced the equipment is, only when the user truly understands and integrates into it can it play its due role in various unexpected situations. ”Zhao Qiang said. Over the years, he has learned and grown together with this' national treasure ', and has honed his skills in numerous radio wave battles. Radio waves are intangible, yet silently and firmly engraved on the longitude and latitude lines of the vast ocean. ”Zhao Qiang said, "My comrades and I will continue to use this square screen as our outpost, infusing our passion and infinite loyalty into the deep blue trajectory of the ten thousand ton drive
