In the depths of winter, fighter jets line up and engines roar at an airport in North China, marking the beginning of a multi batch and multi course flight training for a certain Air Force aviation regiment. With the smooth landing of the Warhawk, the commander of the regiment, Dong Jun, successfully completed the final flight assessment for the combat qualification modification of a certain type of aircraft, including inspection and reception, cabin closing and debugging, following orders to slide out, and boosting takeoff. For many years, Dong Jun has adhered to the front line of flight training, completed the modification and leading trial of multiple domestically produced new aircraft, and was awarded the second-class merit once and the third class merit twice. He was commended by the Air Force as an "excellent Communist Party member". Devoting oneself to sharpening one's sword and taking on the responsibility of flying is the career of the brave, and as a pioneer in the development of new fighter jets, one is also a 'dancer on the edge of the knife'. Dong Jun has been engaged in leading trials of new aircraft and innovative tactical tactics. He said, 'We must practice flying hard, constantly expand the performance limits of aircraft, defend our country's airspace with stronger capabilities and more reliable means, and protect the lights of thousands of households!' Changing clothes first requires' changing brains'. Every time a new model is modified, the relevant knowledge needs to be learned from scratch. Especially in the face of cross generational modifications, it is an upgrade in thinking and a revolution in philosophy. From the moment we first came into contact with the J-20, everyone devoted themselves to sharpening their swords, practicing one stroke at a time, and breaking through each level one by one. ”Dong Jun recalled that after flying the J-20 fighter jet, whenever he had time, he would immerse himself in analyzing training videos, carefully reviewing aerial scenes, from ideas and concepts to control habits, from discovering shortcomings to finding solutions, constantly thinking and deducing, and practicing and improving through repeated flight training. Flying beyond the performance boundary will encounter more unknowns and challenges, as well as greater risks. During a training session, Dong Jun was about to land his plane when a sudden emergency occurred. Despite the pressure, he controlled the plane to land smoothly. Faced with the concerns of his comrades around him, he only comforted them with a word of relief: "Don't worry, no problem!" In this way, he led the team to overcome more than 10 technical difficulties in three months and achieved combat effectiveness in the same year as the new equipment was installed. As the "leading goose" of the team, Dong Jun took the lead in testing new aircraft and exploring new paths. Whether it was urgent tasks or high difficulty courses, he always took the lead and stood at the forefront. He was the first to fly long endurance, the first to achieve low altitude refueling, and the first to undertake combat readiness duty... Dong Jun fulfilled his resolute oath of "fighting long and hollow to the party, flying thousands of miles without getting lost" with continuous "firsts". In order to win in 2020, a high-intensity free air battle is raging in the long sky of the northwest desert. Enemy tracking! ”Above the clouds, an alarm suddenly sounded. Dong Jun remained calm and composed, quickly pulling the lever and jumping to a high position to maneuver and evade. In the frequent occurrence of extreme overload and extreme elevation warning on the fighter jet, he closely cooperated with his teammates, flexibly used tactical tactics, seized the attack window, intercepted the enemy plane, and hit it with one strike. At the moment of decisive battle, Dong Jun's crew became more and more brave as they fought. They maneuvered at high speed in 60 seconds, completed multiple tactical actions, and won the first "Golden Helmet" of a certain type of crew with a large score of four wins in four battles. The team was awarded the "Winning Unit". Only by training like in battle can the blade of victory become increasingly sharpened. During a confrontation exercise in 2022, Dong Jun had just completed a combat mission and was preparing to return when he heard a ground report stating that there was an 'enemy aircraft' in a certain direction. The opponent reveals a loophole, the fighter jet is fleeting, and at critical moments, we must face the enemy head-on. After completing aerial refueling, Dong Jun piloted the J-20 to launch a low altitude attack and successfully shot down the target. Faced with multiple "enemy planes" pursuing him, he calmly responded and flexibly handled the situation, ultimately successfully returning. Dong Jun led the team to persist in using research on air combat issues to drive the generation of new quality combat capabilities in the troops, strengthen innovative research on air combat tactics, and effectively improve the success rate of mission implementation. Winning is the best responsibility. The airspace of our motherland cannot be violated! No matter how high the risk is, as long as we give the order, we will take off without hesitation! "Dong Jun said. As difficulties were overcome one after another and a group of key personnel grew, the cross generational advantage of new equipment gradually transformed into a systematic combat victory, and Dong Jun and his comrades flew towards higher and farther goals. Gathering strength and soaring high as a leading goose: 'Fighting is not just about a few people, a strong team is the real strength.'. ”Dong Jun is well aware that as one of the first pilots of the J-20 fighter jet, he is like a "leading goose" in the sky. He must train his wings hard in order to lead the "goose flock" to fly towards a wider sky. With the completion of each training task, the pilots of the regiment have steadily improved their tactical literacy, application of tactics, and combat style. Strong internal skills and courage are only meant to seize the opportunity when the sword is shining in the sky. To control the heavy weapons of the country, it requires generations of people to lift each other up and work together to accumulate strength. Dong Jun always shares his flying experience without reservation, helping young pilots grow. The "Combat Flight Outline" of a certain aircraft model that he participated in writing has been popularized throughout the Air Force, and dozens of pilots have been trained and trained, gradually growing into the backbone force guarding the national airspace. Dong Jun made his first public appearance piloting the J-20 fighter jet at the 14th China Air Show in 2022. Four silver gray fighter jets accelerated through the clouds and flew towards the sky, with four diamond shaped formations circling. The two planes crossed at high speed, with each plane performing two half roll maneuvers, horizontal flips, and sharp oblique descents... The J-20 fighter jets danced vigorously in the sky, winning rounds of applause from the audience. With mission expansion and equipment updates, our generation of pilots is born into a great era and has more opportunities. ”Dong Jun said that more and more young pilots are piloting new types of fighter jets, accelerating takeoff and leaving magnificent trajectories in the airspace of major countries. We need to better integrate our personal struggles into the practice of building a strong military, take the path of practical training, and strive for victory in battles, bravely becoming pioneers in exploring the blue sky.
