Breakthrough in the air seems very simple, but how to say it, modern warfare is really not about being powerful but invincible, everyone is equal in front of bullets.

Although the Northwest Wind Air Defense Missile is also known as a portable missile, how to say it is not a simple missile, but it can form a unit of an air defense system.

The Army-type Northwest Wind missile has three modes. It is a group of two people, with a tripod, used as a portable air defense system. It is also a Northwest Wind Air Defense missile. It is installed on a vehicle and equipped with a search radar. It can detect air targets from many kilometers away. Not only can it hit aircraft, but also cruise missiles, but it is also a ground-based air defense type. With a large radar, it will search for a longer distance. Small radars are closer to search, but it is impossible for a helicopter to rush through the missile position before being discovered by the search radar.

The portable northwest wind can detect and attack targets of 6,000 meters as far as the distance. Using search radar, you can discover high-altitude targets of dozens of kilometers away, low-altitude targets of ten kilometers away, and ultra-low-altitude targets of five kilometers away, such as flying objects with an altitude of fifteen meters. After discovering the search radar, you can wait for the flying objects to reach the missile range and start fifteen meters away.

In order to support the Syrian rebels, France spent a lot of money. The cheapest portable system also cost more than 100,000 US dollars. What's bad is that France provides not only portable systems for free, but also two sets of vehicle-mounted air defense missile systems. Moreover, these two sets are all in Aleppo.

I know how much does a set of on-board air defense systems such as search radars and laser rangefinders cost? The cost price is 8 million US dollars per set. There is no need to bargain. This is the internal purchase price of the French army.

The information Gao Yang received was so reliable that it was no longer reliable. The missile that he did not dare to take even if he had a plane was the one who had Polovic's former subordinates resold to the rebels surrounding the Aleppo prison.

So it’s not that you are timid, but that under the conditions of modern warfare, you have to believe in science and respect science. France is also one of the five major talkers in the world. The Northwest Wind Missile System is also the main weapon of light air defense. It’s not a joke.

Also, the Northwest missile system is the world's sales champion of portable air defense missiles, which has defeated the sales champions of famous brands such as the American Stinger, the British Starlight, and the Russian Needle.

If it weren't for the rebels' air defense missiles, Gao Yang would have run away.

Of course, the Northwest Wind missile is not unsolvable. If it can fly at an ultra-low altitude, the missile's infrared seeker cannot be captured and locked. It can also safely break through the air defense network of the Northwest Wind missile. But the problem is that this ultra-low altitude is really ultra-low altitude, and the minimum height of the northwest wind is fifteen meters. To ensure safety, it must be less than fifteen meters.

What is the concept of fifteen meters?

Below 100 meters, it is an extremely low altitude. If you lower the height to a height below 15 meters, it is really flying close to the ground. Let's put it this way, if you are not careful, the telephone pole can poke the helicopter down.

The height of the ground is not constant, it has buildings, mountains, hills, towers, wires and flagpoles.

Flying at ultra-low altitudes, below fifteen meters, is not so easy during the day. Whether you watch movies or TVs, do helicopters fly at ultra-low altitudes, and they may be very low when taking off and landing, but after flying, there are no places that fly close to the ground. Unless it is a simple terrain such as water or grassland, there are a few people who dare to fly below fifteen meters, and they don’t dare to shoot like this.

Why is the American longbow Apache armed helicopter powerful? Because a millimeter-wave radar called the longbow is installed on the top of the set, which can search and attack hidden targets at the height of the treetops. The search distance is long and can be used for ultra-low-altitude penetration at the height of the treetops. Before other people's radars discovered it, the longbow Apache emerged.

The United States is the world's number one military power. Russia may not be able to do what the United States can do, but Syria cannot do it, and Mi24 cannot do what the Longbow Apache can do.

Longbow Apache can fly at night, but the old version of Syria's Mi24 is far from that. It can fly in the transition at night, but if you want to fight, you are almost the same in dreams. Without a night vision system or a good radar, you are like a blind man. How to fight?

Gao Yang and his team bought a night vision device and modified two Mi24s, which is very important because after the modification, Mi24 has initial night combat capabilities, but if they want to fly at night ultra-low altitude, the limited modifications that Mi24 have undergone are reluctant to be difficult.

The Apache helicopter has an automatic terrain following system and a terrain following radar, and Mi24 has nothing...

What is terrain follow radar? Terrain follow radar means automatically detecting terrain changes and then automatically notifying the pilot. For example, when flying, a tree suddenly appears in front of it and can hit a helicopter. The terrain follow system will notify the pilot, and then the pilot can control it and dodge it.

Gao Yang can use Mi24, only one night vision device can help you with night flight, and it has limited help.

Infrared night vision devices cannot be too large. When flying at ultra-low altitude, due to altitude, the onboard night vision devices can only see a very small angle in front of them, and then present the image on a very small screen. Even if there are obstacles, whether it can be discovered on the screen in time is a problem. It is better to use a helmet night vision device than to control the plane when staring at the screen.

Helmet night vision instruments cannot be like the daytime, but they are limited distances. After all, it is an electronic re-imaging device. It is impossible for him to see as clearly as the naked eye during the day. There is no problem with infantry combat. However, the pilot flies at high speed at a very low altitude and uses the helmet night vision instrument to see a telephone pole a hundred meters away. From discovery to the operation of the aircraft, how long can the pilot take?

Based on the flight speed of 100 kilometers per hour, the speed of 100 kilometers per hour is twenty-eight meters per second. From discovery to having to avoid it, the pilot only takes more than three seconds. Moreover, when the pilot sees everything from the pilot's eyes, everything is super fast. It is hard to say whether it can detect the telephone poles in time. So how difficult it is and how dangerous it is, you can imagine how difficult it is.

The danger of ultra-low altitude flight at night is no less than that of flying out at high altitudes during the day, threatening the northwest air defense system.

To improve safety, the pilot of the Mi24 must be the best pilot. Ordinary people dare not fly like this, and they must be two excellent pilots. The weapon operator stares at the screen of the airborne night vision device. If there is any danger, please remind the driver to wear a night vision device with a helmet. At night, the two people must cooperate with each other to complete the task.

Of course, doing enough homework before flying, such as flying from a familiar waterway, flying over the enemy's head at the shortest distance, and knowing obstacles on the flight route can also reduce some danger.

Now, the four pilots Polovic found have arrived in Damascus, and Gao Yang has just received the notice. However, they have to study at least two or three days of navigation maps and plan the safest flight route. They can only pick them up after they keep it in mind.

The preparations before the flight were only done by those pilots themselves. Gao Yang would definitely not be able to help, but Aleppo Airport had sent two familiar pilots to Damascus Airport to help Polovic's Russian pilots formulate flight routes.

For an inconspicuous evacuation work, the manpower and material resources are consumed. Experts look at the tricks and laymen watch the excitement. Those who don’t understand see the helicopter fly over and pick them up and get them away. Only those who understand the difficulty can know how difficult this seemingly simple flight is and how powerful the pilot is.

Gao Yang didn't know very well, but he could barely know a rough idea. If he hadn't learned flying, hadn't he learned to use helicopters to conduct ultra-low altitude raids in Israel, and knew the difficulty, he would have thought that he would just fly over.

The older the world, the less courageous he is. The ignorant is fearless. All the same thing is said. If you don’t know how powerful he is, maybe Gao Yang ordered the helicopter to pick him up and leave. It was because he knew the power of it that Gao Yang was locked up and was anxious. After he could not see the hope of leaving for a long time, he was willing to make a forced breakthrough under the conditions of acceptable risks.

The closer he was to the day of leaving, the more complicated Gao Yang felt. He was looking forward to leaving, and was worried about being knocked down in the air. But in general, he was still happy because after all, he could leave immediately.

Gao Yang had too many things waiting for him to do, but Gao Yang had decided that after leaving Aleppo Prison, he would do three major things first. The first thing was to eat, and have a big meal first.

The second thing is to have a big meal.

The third major thing is to have a big meal.

It took more than a month and a half, Gao Yang had never eaten a full meal, and there was nothing else every day except two palm-sized noodles. The fresh meat sent to the prison was finished in one meal. Then he ate the noodles for more than a month, and he drank the canned meat in the middle of the day. During this period, he drank the canned meat. The ten Satans ate two canned meat in a separate meal, and they were as happy as the New Year.

During the three years he was a savage in Africa, Gao Yang had never suffered so much. Although he was hungry and full, he still had plenty of time. It was not like this one and a half days of eating noodles. He was hungry all the time. Therefore, the only thing Gao Yang had set for himself was to eat. He went out of prison and ate it wildly, and then he had enough money first.

The day has been set. During the day on February 7, two Mi24 will take off from Damascus to Aleppo, and then refuel at Aleppo Airport after maintenance and adjust everything to its best condition. At 3 a.m. on February 8, the helicopter landed in the Aleppo prison and picked up Gao Yang and the others to leave.

Today is February 6th. (To be continued, please search for Astronomy, novels are better, updated and faster!

ps: I went to the hospital today to check my legs and was so tired that I wrote this chapter too late. I apologized first, but I still have to ask for monthly tickets. At the end of the day, I can't leave it.

Also, I would like to explain why this chapter was written, and I didn’t plan to write it, but a friend asked me why I didn’t use a helicopter to pick up people and left. I thought that there are many friends who are not military fans who don’t understand the key, and may have the same questions, so I wrote it, so everyone knows what’s going on.
