"Hurry up, this is the four J-18 fighters that have just come off the assembly line this time, just fly it back if you need it, and after landing, there will be relevant staff to contact you, and the four of you will be taken to the designated place to prepare, understand?"

No one knew that somewhere in the central region of the republic, which was already a semi-abandoned military airfield, when it was just getting dark, two batches of the republic's most advanced third-generation military fighters, a total of eight planes, landed here, and no one even knew that among these eight fighters, there were only four external numbers. Pen, fun, pavilion www. biquge。 info

In the vast darkness of the night, the ground crew quickly completed ground tasks such as fuel refueling, and it took less than 20 minutes for the ground crew to complete the maintenance and overhaul tasks of the two batches of fighters.

Taking advantage of the dark night, the pilots boarded the fighters that had been replaced, and the turbofan 12 engine pushed the fighters to quickly taxi and take off, and the pilots in the cockpit could clearly feel that the fighters under their buttocks were no longer as familiar as in the past, but with the long-term flight training for half a year, the familiarity with the model could already ensure that the new aircraft could be easily controlled, and now the plane only needs to fly back safely.

In the center of the ground tower, watching the four planes complete the formation and slowly fly away, the task at this time finally had a good start: "Smooth takeoff, so when do the other four fighters plan to leave?" ”

At this time, the four fighters left on the ground and have not yet taken off are naturally the full-state J-18 fighters that were replaced from the active forces before, and they can fully meet the secret combat missions planned by the army, that is, at this time, all the fighters used to carry out combat missions are enough, the four fighters are quietly parked in the dark, the navigation lights emit a faint red, and the pilot sits in the cockpit and responds to the take-off command at any time.

In the end, the group said goodbye to the staff on duty at the tower and prepared to leave, leaving a sentence: "When the fighters are released, that is the business of your tower, you just command them to take off safely." ”

With the second batch of four J-18s ready to take off, the ground take-off preparation area began to withdraw the ground support personnel, leaving only the take-off dispatcher waving the baton in front of the fighter, and the luminous baton in the dark night drew different trajectories.

With the light steering of the nose landing gear headlights, it also means that the direction of the fighter's taxiing changes, and the constantly flashing navigation warning lights tell everyone that the second batch of J-18s in the dark night began to transfer, followed by the second, third, and fourth planes that followed one after another, and the fighters entered the taxiway in turn and took off in turn. Naturally, its destination is to return to the test flight site station in the southwest of AVIC, where there is corresponding maintenance and support equipment, which can inspect the 10 fighters on this mission and ensure the delivery of the fighters the next morning.

A Y-7 100 passenger plane in the tarmac, which belongs to the military's commuter transport plane, carrying the relevant staff who came to preside over the exchange of two groups of fighters, also took off in the dark night, and as time passed, it disappeared into the boundless darkness and flew to a farther destination.

In the same dark night, on the Yunnan-Guizhou Plateau in the southwest, Yang Hui waited here for a long time at the test flight delivery center in Guiyang Aviation Industrial Park, and since the four J-18s that failed to reach the full state of delivery at the test flight station in the afternoon flew away, the test flight delivery center has been out of martial law, especially the periphery of the test flight delivery center, which has actually been controlled by the local military.

"Everyone hurry up to carry out the final inspection of the fighters, this time the military's actions are not small, but we can't have a business trip here, otherwise our life will definitely be difficult in the future, so everyone must be more careful, just now after this period of time has passed, the situation may be clear enough, I promise to give everyone a good holiday at that time."

AVIC Southwest up and down since the middle of 95 years after receiving the military order, has been ten months of long-term full capacity capacity, the pulse production line on the production team can have two teams shift production, but the work of the test flight delivery center has no way to shift shifts, all rely on the staff to work overtime to be able to progress better, really to say that the holiday, the staff of the flight delivery center should be the most should be the first holiday to rest and rest.

"Mr. Yang, the plane over there has flown back and is about to land, should we not go to the runway to have a look?"

After waiting for so long, the four J-18s finally flew back, this married daughter has a rare opportunity to go back to her parents' house once, she should indeed go to the door to greet her, tighten her clothes, the Yunnan-Guizhou Plateau in March is still a little cold, especially at night, I can't help but shiver when I go out.

"Okay, let's go to the runway to greet us, our daughter will go back to her parents' house once, no matter what the purpose, everyone should be happy!"

When they came to the runway, in fact, the four planes had completed the landing procedures, and the ground crew was towing the planes to the indoor parking shed, where the ground maintenance personnel had already prepared, and the maintenance work of these aircraft had to be completed in the shortest possible time.

In fact, when the J-18 is designed, it pays great attention to maintainability, especially through the practice of the previous J-74/5, JF-17 Lightning and other fighters, although the current J-18 has not been able to reach the level of automatic computer maintenance, but the J-18 in the design at least focuses on optimizing the installation / disassembly of parts that need to be maintained and inspected frequently, various quick-release port covers, special testing equipment, etc., are also essential things, and now the maintainability of the J-18 is already the level of fighters in Europe and the United States in the late eighties, In addition, the design of the J-18 is not too complex and sophisticated, and the maintainability can be completely comparable to the original F-18 Hornet fighter of the US military.

"How? What is the state of maintenance of the fighter? ”

"It's pretty good, the troops are in strict accordance with the maintenance manual to carry out maintenance, at most four hours, we will be able to complete the comprehensive overhaul of these four fighters, look at this state, we can guarantee the delivery of ten fighters in full state tomorrow, single-seat A type 8, two-seat B type 2!"

Ten fighters were used for this mission, this is already the result of the best efforts of AVIC Southwest, and then heard the sound of the propeller of Yunqi outside, at this time I also put down a big stone in my heart, this time the task of delivering the fighter of AVIC Southwest has been completed, and then it depends on the army's own ability, what Yang Hui can do is to wait for a few days under the supervision of security and confidentiality personnel.
