sometimes

Squall, storm also.Wherever he went, heavy rains came suddenly, the temperature plummeted, lightning flashed and thundered, and the sky and the earth changed color.

In particular, the instantaneous change in wind direction and sharp increase in wind force brought about by the squall line will pose a major threat to the flight of fighter planes, ship navigation and the safety of ground facilities, which is why the exercise was forced to be suspended.

Yan Dingbo put the telephone into the hand of the political commissar: "Call the headquarters, ask if the blue team can be forced to return, it's too dangerous."

The correspondent turned back and said: "The blue team has already evacuated to the northeast, and it is estimated that it is out of the warning range of the squall line at this moment."

No matter how fast the cold air mass moves, the speed is only a dozen or tens of kilometers per hour at best, and the most fuel-efficient cruising speed of J-100 can also reach subsonic speed.As long as they want to go, it is easy to leave the thunderstorm cloud behind.

To the northeast of Shanhaiguan is the so-called "undetectable" base.They returned.

"I don't like to hang out with people from the weather station. It's windy and rainy tomorrow, and I always speak inaccurately." The political commissar raised his hand and frowned, "Who said that they have mastered the weather information collected by the blue party?" Evidence? Didn’t they say that Shengjing Port was [-]% beaten? Why did they run to Shanhaiguan against the wind? Besides, they were too messy this time. dead?"

There was a moment of silence in the control room.

"No." Yan Dingbo said slowly, "This is just an exercise. Yan Ming believes that he can win, and he can also afford to lose, but he will never let himself and his teammates risk their lives, not to mention that they are carrying state property. .To take such a big risk...I think they should have accurate information."

——In the night when the first batch of unmanned reconnaissance planes never returned, Jun Yang asked with a cigarette in his mouth: "Does the satellite cloud image for weather forecast work? The one on TV."

"Of course not. What is needed now is 1×1 kilometer grid and minute-level precipitation. Who do you ask to read this for you by looking at the national map? What the hell?" Zhang Yuanzhou dispelled his unrealistic thoughts, He asked again, "Why are you thinking about this again, don't we have intelligence?"

"The unmanned reconnaissance plane was launched in the middle of the night, and it flew away. It must not be homesick." Jun Yang twirled the thick stack of documents at hand with his fingertips, and whispered, "The person on the other side Staring at us non-stop, do you think these things are reliable?"

Zhang Yuanzhou thought: "White people often feel unreliable, but if you take a little and let it go, you will think that your luck suddenly exploded in the rough days and you picked up a leak, and you will be extra treasured. For example, you—— "

Jun Yang paused with a cigarette between his fingers, and glanced at him: "What's wrong with me?"

"I thought you just had a little more practical experience than the average instructor, and a little faster reaction speed than the average nerd, but because of your withdrawn personality and not being gregarious, you were buried in the corner of the flight academy. If no one gives you a hand , You’ve been living like this for the rest of your life.” Zhang Yuanzhou looked at the two cabins not far away, and said, “Don’t believe it, many people’s talents are quietly worn away by time like this.”

Jun Yang was noncommittal: "You think too much."

"I really think too much." Zhang Yuanzhou sighed, "You have shown great interest in reverse combat, just like an autistic patient suddenly opened his heart. As a witness, I am embarrassed to discourage your enthusiasm. Who knows Once here, you have been completely reborn. Every time I see your eyes, I feel that you are not a hot-blooded whim, but you are here to sort out order. I don’t know which one is the real you. I was wrong. , or is there a magnetic field in this place that can change people's temperament?"

"Magnetic field?" Jun Yang showed a rare smile when he had no clue, "There is a magnetic field."

Zhang Yuanzhou looked at him in confusion: "Is it because you and Captain Yan have known each other for a long time, so you are working hard? Next time I have something to ask you, will you support me like this?"

"Let's look at the situation this time first." Jun Yang twisted his cigarette butt, "Is there any commercial way to obtain information now? We can't leave the system in vain, it must be a little convenient."

"Weather releases are regulated by the state. Enterprises usually buy data directly from the National Meteorological Bureau. Therefore, the development of private weather stations is generally not very good. Most of them are leather bag companies. Besides, even if there are, I am afraid that they are not as authoritative as the data in the meteorological database. " Zhang Yuanzhou thought for a while, and then said, "However, some satellites provide some data sharing and can be accessed directly. We can try it."

In the weather cabin, everyone gathered all the information that could be intercepted, including weather forecasts for the local area and surrounding areas, observation reports downloaded from various websites, trial weather information products from paid satellites, and so on.

Facing the mixed data, the forecaster awkwardly picked out a few obvious features, pointed to a vortex cloud system and said: "From the picture, this may be the cold vortex itself, and the thunderstorm cell and cumulonimbus cloud are here. Organization is moving from southwest to northeast and is expected to be strongest along the coast."

"This is Shanhaiguan, Kutao Port." Jun Yang followed the direction of his finger, pointed the tip of the pen on the only way the clouds must pass, stared at the unnamed bay for a few seconds, and asked, "There is a chance of special weather ?"

The forecaster consulted several data and said conservatively: "There is a possibility of a squall line forming, you can observe it again."

Jun Yang asked, "What if it is possible?"

"If extreme weather can form and the clutter noise reaches a certain level, the radar will adjust the threshold level according to the Neyman-Pearson criterion to ensure that the signal-to-noise ratio maintains the original false alarm probability." The forecaster explained, "We You must first know the inherent noise level of the radar receiver, and then install electronic pods on the stealth fighters on the front line to capture weather clutter signals. You should be able to calculate the maximum allowable interference level of the radar, and the minimum interference level after the threshold is adjusted. Detectable signal."

The forecaster wrote while talking, and listed a bunch of equations, even Zhang Yuanzhou couldn't help rubbing his eyes.He was about to pat Jun Yang on the shoulder to signal him to persevere, but when he turned his head, he saw that Jun Yang was staring at the paper without any signs of fatigue.

Jun Yang asked: "Are you sure that's the way to calculate it?"

Zhang Yuanzhou turned the paper and looked at it: "If you don't consider other shipboard radars at sea, you can calculate this for radars with a small number and a single model."

"When the ship enters the port to avoid the wind, it will protect the antenna and radar. It is enough to only consider the shore base." Jun Yang said, "But even in a complex environment, the detection performance of the radar is not as good as usual, and it is not enough for the fighter plane to penetrate the defense at high speed. .”

"Of course not fighter jets, but other things can." Zhang Yuanzhou took out a piece of paper and listed a few lines of formulas, "We can use small, low-speed and low-altitude aircraft with low metal content in the body, reduce the echo signal strength, and do as much as possible for the shape. Flexible processing, dilute the characteristics of the aircraft, and if time permits, it is best to add camouflage and deception jamming, or a false target generator."

Jun Yang's eyes lit up, and he asked: "If you want it to fly near the ground radar and irradiate the target with lasers, what other conditions do you need?"

"The most important thing is the timing of releasing the drone." Zhang Yuanzhou said, "It must be after the radar adjusts the threshold level and before the squall line actually arrives. There may not be very much time in between, and even It only takes ten minutes, or a few minutes, and at the same time, it is necessary to control the drone to land in a place with few people so as not to be discovered. Therefore, to see if there is a chance, we need more horizontal and vertical scans of clouds to judge their In addition, the size and intensity of the cold vortex must be supported by the short-term radar layer to grasp the moving speed of the cold vortex."

While they were discussing, several other people at the weather station started to use their independent computers to search the Internet: "This website seems to be good?"

Another person said: "If the product can have this kind of clarity, then it is really possible."

There was a tsk tsk tsk tsk sound from behind Jun Yang: "It's so expensive. Is this price serious?"

"Hey, do you think polar-orbiting satellites are launched casually? Besides, it doesn't cost money to build observation points..."

Jun Yang said to Zhang Yuanzhou: "Check, is the Kutao ship in Hong Kong recently?"

"I have been in the observation center of the headquarters for a month, and I have never heard that the Kutao ship has exercises." Zhang Yuanzhou recalled, "If they are nearby, they should participate in joint exercises as in previous years. No, it is estimated that he went to sea to perform a mission."

At the beginning of the design, Kutao Port was mainly built around serving the Kutao ship and its battle group.When the Kutao ship is not near Shanhaiguan, the number of personnel and the air defense system in the port cannot be saturated at all times, otherwise it would be too wasteful of resources.Besides, without the Kutao battleship battle group, the combat effectiveness of the port would be greatly reduced.

"Buy." Jun Yang turned back and said, "I will pay for whatever I need."

Zhang Yuanzhou hurriedly stopped him: "Don't, is it reliable? You don't even ask the customer service first! Look at the reviews! Check your qualifications!"

"Time is running out." Jun Yang pointed at the information on the desktop, "The third party is at least a little more reliable than this."

When Yan Mingxin woke up, he saw Jun Yang sitting beside the bed.

He held a chart in his hand, with a step-by-step plan densely written on the edge.

"Avoid ships returning to Hong Kong, approach Kutao from the waters with complex hydrology, and drop drones; the G-02 tanker is on standby in the airspace of the Mother Sea, ready to deliver fuel to the J-100 team..." Yan Mingxin After reading a line in a daze, sighed, raised his hand and rubbed his head indiscriminately, "Did you sleep last night?"

Junyang and the staff of the two stations collected data overnight, sorted out calculations, combined with marine hydrological elements, and drew a chart.

In the second half of the night, he relied on cigarettes and tea to cheer himself up. At this time, his voice was hoarse and he said haggardly, "I don't care."

"Stinky boy, you put me to sleep and ran to help me with my homework." Yan Mingxin murmured and scolded him, stretched out his hand, and hugged him with the person and the picture in his arms, close to himself, "Okay Leave it to me, you rest for a while."

After one sentence, there was another slight snoring sound.

"..." Jun Yang patted him on the back lightly, "Can you do it? Are you awake? I'll go with you."

Yan Mingxin's spirit was as clear as ever, but his body was weak and slow to wake up due to excessive overdraft.He complained, "You don't know if I can do it or not?"

Moaning twice, he said again: "You have written the answer for me, and you just wrote the punctuation marks, can I still not understand?"

Everyone in the war room gathered again to analyze the feasibility of this plan.Jun Yang's heart was hanging, and he couldn't sleep for a while, so he still came together.

Lin Jisi pointed to the deception mission in the direction of Shengjing, and said, "I'll do it."

Jun Yang raised his eyes quickly, glanced over sharply, stared at him and asked, "Why?"

It is impossible for a man to join the army without a little selfishness to make contributions.If what is pursued in war is victory, then what is pursued in exercises is the amount of bombs dropped and the hit rate.

The deception mission in the direction of Shengjing Port has almost no chance of firefights, and even if there is, he will be beaten. As a pilot of J-100, Lin Jisi will take the initiative to reduce the dimension and ask for this tasteless position, or he has no confidence in the raid and feels that he has gone dry. Tao also returned in vain, either because he had a lot of trust in the trip and was willing to be a pawn with enthusiasm.

Jun Yang pressed the question too quickly, and Lin Jisi was momentarily at a loss when he asked: "Only Captain Yan and I heard the whole story from beginning to end. Of course I went. And the speed of advance and retreat in the air defense zone, I personally think, depends on It would be better for me to handle it."

He doesn't look like the former, nor does he look like the latter, but he looks like a big brother.Not only took Yan Mingxin's situation into consideration, but also took care of other teammates.

Jun Yang couldn't tell what he put down in his heart, but he felt sleepy all of a sudden.

Out of the corner of his eye, he glanced at Zhang Yuanzhou beside him, who also drooped his eyes half-deadly.

Yan Mingxin had no objection to Jun Yang's allocation, and assigned the tasks properly according to the scriptures, and said: "This plan is temporarily designated as Plan A. In the next half day, we still need to continue to look for other breakthroughs, so don't slack off because of this."

Zhang Yuanzhou struggled to sit up in drowsiness, and Jun Yang also came back to his senses: "Why is it temporary?"

"It's not that I don't believe you." Yan Ming believed, and looked at Zhang Yuanzhou again, "It's not that I don't believe you."

He turned back a few pages, pointed to the footer of the information, and said: "All calculations are based on the data provided by third parties. I cannot fully trust them. They must be verified first—whether this thunderstorm group is formed or not." The squall line and the weather forecast around Shanhaiguan will definitely be mentioned. In the next 24 hours, we will monitor all frequency weather forecasts and sea surface warnings, and extract information related to Shanhaiguan from them. If it completely coincides, we will implement this plan, otherwise it will be invalidated.”

After the meeting, the squadron leaders went back to distribute the charts and convey the combat missions. Yan Mingxin left Jun Yang and Zhang Yuanzhou behind and said, "You two have worked hard. I personally thank you for your efforts, but I can't let anyone take risks. , I still hope to understand."

"I won't let you take risks." Jun Yang replied, "If the timing is wrong, this plan will be canceled, but if the timing is right, we will definitely succeed."

Zhang Yuanzhou was in it, and wondered if it was because he had been working all night long, and his overwork had given him the illusion—he always felt that he was superfluous, and he didn't need to speak at all.

He saw the young captain Yan bent down, leaning on the table with one hand, laughing very softly, and asked in a low voice, "What? You have a premonition again?"

He also heard Instructor Jun, who had been meticulously sculpting hand-painted navigation charts all night long, striving for perfection to the point of penny-pinching and unreasonable, speaking, the rough energy and miscellaneous tobacco smell from when he fought side by side with them all disappeared at some point. Dispersed, said with a meaningful tone in an unserious tone: "Yes, I have a hunch."
