The ice five kilometers downstream of Jiangcheng County is completely different from the iceberg that Li Zhan originally bombed in Beiku, the iceberg is basically a whole piece, just like a mountain, you either can't blow it up, but if you blow it up and destroy its own balance, it will collapse on its own.

Ice cubes are not like this at all, for example, ice cubes are ice hills, not very high but jumble and not connected to each other, you blow some of them up, and the other parts don't move at all because their own balance is not broken.

So the best way to deal with large areas of ice is carpet bombing, the Air Force chose this method very directly after receiving the task, the Air Force has carried out such a mission many years ago, and the carpet bombing has the best effect - since there are no joint points, then I will cover you all, very rough.

The situation Li Zhan faced was very tricky.

The surface of the river, which is hundreds of meters long and dozens of meters wide, is full of ice cubes, just like the bamboo shoots that grow from the bottom of the river. There are several forms of ice, the most common is hanging like a door curtain, and there is a heavy rain in the northern winter, and the rain flows down the eaves, and the temperature suddenly drops to less than zero, and the water that flows down quickly freezes.

The ice on the Huajiang River is formed by the freezing of the river water, and as the water flows upstream, it freezes layer by layer, and finally forms a large ice cube that is now higher than the embankment. The most peculiar thing is that not all of the river surface is frozen, the river water is flowing slowly between the ice cubes, and even the river surface has a layer of transparent thin ice, and the water flows below, like ice cream, with a layer of hard ice on the outside and a solid-liquid mixture on the inside.

The ice is melting, but naturally it is melting too slowly!

In fact, if the local area could pay attention to it and take measures to deal with it at the beginning of the ice cream, the current situation would never have occurred. The natural environment required for the formation of ice cubes is so special that the local temperature continues to rise, and it is impossible to form such large ice cubes that clog the entire river with certain precautions.

It can only be said that the local relevant departments are a little slack.

Li Zhan circled 500 meters above Bingling, and then adjusted the direction of the nose of the plane to fly slowly at an ultra-low altitude along the side of the river bank from west to east. The relative altitude was thirty meters, the river was on the left flank, and the fighter plane was basically flying over the embankment on the right bank.

He was a master of the arts, and very few pilots dared to do this, especially at such a low altitude, where wind shear was a disaster, and even a slightly stronger crosswind could be dangerous.

He couldn't take care of the urgency of the situation, according to the flow speed of the flood peak, it would take ten or twenty minutes to hit the ice cube, and he had to determine the attack plan in the shortest possible time.

But after flying back and forth, Zhang Xueyang's brows were wrinkled together, and he said solemnly, "It's not easy to do, the shortest position is more than 200 meters, and we are not sure how big a bomb can play at all." ”

More than three tons of aerial bombs seem to be a lot, but in the face of large and small Xiaoice on the surface of the two or three hundred meters of river, it seems a little stuffed.

Li Zhan made a U-turn over the county seat, and had already seen Hong Feng enter the western suburbs of the county, and now he was going to race with Hong Feng. If there is only one flood peak, it will be fine, even if it is poured into the county seat, the impact is not great, the question is that Li Zhan saw that there are at least seven flood peaks just now, and whether there are still locations further upstream I don't know.

The water level itself is very high, and seven consecutive flood peaks rush over, and the sudden flood water will directly turn the county into a water city, and the county's prostately enlarged sewer system cannot be expected to play any role.

It may be that the people in the county town have been comfortable for a long time, the sense of crisis has weakened, the transfer work is not going well, and many people feel that there is nothing to do, and even start a guerrilla war with government workers and officers and soldiers of the army - I don't think there is much water in the river, nothing to do!

It is true that the river section in the county is calm, and the water level is higher than usual, but the flood is not weaker than the mountain fire at all, you look at the distance and feel that it is okay, maybe it will be in front of you in the blink of an eye, and there will be no chance to run by that time!

The general finger informed Li Zhan of the transfer of the county seat, and Li Zhan was even more anxious.

"I can't hesitate, carry out a line of horizontal bombing along the middle line of the river, you quickly determine the bomb delivery interval and give me altitude speed!" Li Zhan gritted his teeth and said.

Zhang Xueyang didn't talk nonsense, and quickly calculated. In order to ensure that all the bombs fall evenly on the middle line of the river, it is necessary to consider the flight altitude, airspeed, acceleration and inertia distance of the bombs, which are very complicated calculation formulas. If it is the latest H-6, these can be handed over to the automatic bombardier, but the J-15S does not have this thing, the bomb is an ordinary contact fuse, the pilot releases the bomb, the bomb falls freely, and it will move in the direction of the fighter flight under the action of inertia, and explode after hitting the ice.

However, these were not difficult for Zhang Xueyang, he quickly came up with the results, and after Li Zhan completed his U-turn, he said, "The altitude is 550, and the speed is 370!" ”

"Understood!"

Li Zhan quickly adjusted the flight parameters.

It is necessary not only to take into account the problem of uniform landing of the bombs, but also to ensure that the fighters are at a safe distance when the bombs explode. The two data given by Zhang Xueyang are basically the minimum security standards, and they must take risks, and only by doing so can the effect of horizontal bombing be the best.

The first drop point is very important, and the coordination of the pilot and the weapon operator is very important.

"Five-second countdown!" Zhang Xueyang shouted.

"Keep up the speed!" Zhang Xueyang reminded.

"Three, two, one, bomb!"

Zhang Xueyang put down the first group of bombs, the weight reduction fighter lifted gently, Li Zhan quickly stabilized his attitude, Zhang Xueyang pinched the bomb interval, and then put down the second group of bombs, the fighter lifted lightly again, Li Zhan quickly stabilized the fighter posture, so cooperative, quite tacit.

The third group of bombs had just been put down, a huge explosion came from behind, and the shock wave generated was like a big hand pushing the fighter, the fighter staggered forward a few steps, Li Zhan was prepared, quickly recovered the attitude of the fighter, and then when the fourth group of bombs was released, the second group of bombs exploded, and the bomb dropping point was very accurate from the interval point of view!

If you stand on the bank of the river and look over, you can see a fighter plane flying flat in the direction of the river, and then constantly dropping the bombs like a hen laying eggs, the bombs fall almost at the same interval, and the ice cubes that have been blown up are wiped out, and the water mist and the smoke of the explosion are mixed together, which is like throwing a small arm-thick cannon into a lime pool.

After all 12 groups of aerial bombs were dropped, Li Zhan quickly pulled up his U-turn and flew to the county seat, and when he turned around over the county seat, he observed that the first flood peak had already entered the county seat, and the people in the county town began to panic. A large amount of water had already overflowed the riverbank, but there was still capacity in the section ahead, and the main force of Hongfeng continued to advance eastward.

Li Zhan sped up his speed to complete the U-turn, flying at an ultra-low altitude along the riverbank to observe the bombing effect, Zhang Xueyang was more nervous than him, after all, this was his first actual battle, although the target was Bingling.

"Not ideal! See that herringbone ice cube, it's so stubborn! Zhang Xueyang said in a deep voice.

Horizontal first-line bombing, the explosion points are neatly arranged along the middle line of the river, and the effect is not very obvious, because if the aerial bomb hits the ice, the effect is worse than falling into the river, and it is difficult to destroy the ice by prefabricated fragments, mainly because of the strong impact force generated by the explosion, and the best effect is when it falls into the river.

The most conspicuous is the relatively large herringbone ice cube in the middle of the ice cube, which is stuck there like a urethral stone, and the water that cannot be seen may be a large stubborn ice layer.

"I'll use the cannon to it!" Li Zhan quickly pulled up the attack route from the east, and now there is something to fight, but fortunately, the artillery is full, there are 250 shells, as for the effect, it is really difficult to say.

Li Zhan's choice to enter the attack route from the east is also considered, the water flows to the east, and the thrust on the ice is eastward, Li Zhan wants to hit the bottom of the east side of the herringbone ice, hoping that this stubborn ice will collapse under the impact of the flood peak.

Then there was nothing to do with Zhang Xueyang, he was responsible for observation and lookout.

The rear seat of the J-15S is higher than that of the J-16 and J-11BS, and the rear cabin weapon crew has a better field of vision, and the control stick between the thighs of the pilots in the front cabin can even be seen in level flight.

So Zhang Xueyang could see the entire county in front of him, but the night had gradually fallen, and the visibility was getting lower and lower, and he couldn't see the situation in the county clearly.

At this time, Li Zhan used the low-light night vision device.

After the nose of the aircraft was aimed at the herringbone ice cube, Li Zhan made full use of the excellent low-altitude performance of the J-15S, controlled the attack speed at 230 kilometers per hour, and after the aiming point was determined, Li Zhan determined the impact point when he was 500 meters away, and then decisively pressed the launch button.

Thirty-millimeter aircraft cannon shells were fired continuously, and in the dim night, the muzzle of the aircraft gun spewed tongues of fire, and every two tracer shells were tracer shells, which gave the shooter a good indication of the trajectory. The metal slug hit the waterline of the herringbone ice cube, like a small supersonic fist raindropping on a two-meter-tall giant weighing three hundred pounds.

The attitude of the fighter will be destroyed during the shot, so it is completely impossible to hit all the shells at one point, but a good fighter pilot can control the impact point within a small range, which is an aerial gun ground attack. When attacking an air target, the test is the pilot's prediction of the target's movements, and the shells fired are arc-shaped.

Li Zhan's performance in hitting ground targets with No. 037 J-7E is still the record of the Second Division, and his marksmanship is absolutely accurate. What's more, now I am driving a J-15S with much better performance at low altitude and low speed, aiming more calmly and shooting more calmly.
