Chapter 857 Continue to Prepare
"Ah? So low?" Not to mention the comrades who were engaged in TV broadcasting, any comrades who knew a little about television would be unable to hold back.

Gao Zhendong smiled: "Yes, it is that low! Don't forget, our missile is used to strike large fixed targets dozens of kilometers away."

Others didn’t quite understand what Gao Zhendong said, but the comrades in the Air Force felt like the door to a new world had been opened.

Yes, this frame rate may not be suitable for hitting other targets, but it is absolutely effective for hitting this kind of target. It is much better than any horizontal bombing or dive bombing!

Theoretically, the current method of arbitrary eye bombing is to aim the bombardier at a "photo" taken with his own eyes.

The problem lies in horizontal bombing. Once the bomb is dropped, there is no chance to correct it. The errors caused by the manufacturing accuracy of the bomb, the airflow in the air, the change in air density, etc. will continue to accumulate.

As for dive bombing, forget it. Facing an enemy with certain anti-aircraft firepower, that thing is very tiring.

Facing away and throwing? There is no need to discuss this. This special method does not consider accuracy at all. What's the use of a few hundred meters?

Correction once per second? With the flying speed of the bomb, theoretically, there is still one correction opportunity when it is 1-200 meters away from the target. Adding the limitations of human reaction speed, there is at least one correction opportunity within 300-400 meters.

Because a bomb without power can never exceed the speed of sound.

This distance is the attack distance of dive bombing, which means that even at 1 frame per second, this bomb can at least achieve an effect similar to that of dive bombing.

As for the dive bombing attack distance of 200 meters, just listen to it. The escape distance is about the same, or it is just a game. Anyway, no one will die, so you can do it as you please.

At this time, the slower flying high-drag bomb actually became its advantage, increasing the reaction time in disguise and shortening the distance for the last correction.

No wonder Chief Engineer Gao said that this type of kit does not need to consider the drag reduction hood. This may also be a reason, in addition to minimizing the impact on the fuzes of some types of ammunition.

Moreover, high-drag bombs are more stable in flight than low-drag bombs and are more practical in this situation.

Absolutely, absolutely absolutely. Thoughtful, really thoughtful!
"Yes, yes, comrade, as long as we can achieve one frame per second, it will be useful to us!" The comrade from the Air Force immediately expressed his opinion.

The chief engineer of the Defense Work Committee asked him, "Can it really be used?"

"It really works, Mr. X. Do you think this thing can be used even if it has a 10% accuracy rate?"

There is a huge difference between 10% hit rate and 10% accurate hit rate.

With this bombing method that can correct its direction within a few hundred meters, achieving a 10% accuracy rate is no longer a dream.

"That makes sense. This thing is used to hit high-value key targets. One characteristic of this type of target is that it doesn't move. The second characteristic is that they are generally large in size. The third characteristic is that they are of high value and worth throwing more at." The chief engineer murmured.

These three characteristics determine that 1 frame per second is really playable!
Since it won't move, the requirements for the bomb's maneuverability and correction are much lowered. Just aim in that direction and fly over. The aiming line is stable, and the designed strike distance is long, so there are many opportunities for correction. The field of view is gradually corrected from large to small, and fixed focus is like zoom.

Isn’t this better than horizontal bombing?

The large size means that even a slight deviation can achieve the desired effect, unlike hitting tanks or small bunkers where the requirements are so high. Moreover, a one-ton bomb can have a great impact on the target even if it is slightly off. No wonder he asked for the smallest one of one ton right away. It lacks accuracy, but makes up for it with power.

Not to mention the high value, for high-value targets, it is impossible to launch an attack with an accuracy at least equivalent to dive bombing from 45 kilometers away! If I can't hit one, I will throw ten or a hundred.

For high-value targets, dropping 100 bombs can solve the problem, which is definitely a good deal, not to mention that according to this design, dropping 10 bombs may be enough to solve the problem.

For the attacker, the risk is low anyway. I can just fly the kite slowly. I can make a hundred mistakes, but the defender cannot make even a single mistake. The worst thing is that even if the defender does not make any mistakes, he still has to pray that the attacker makes mistakes every time.

"Well, Comrade Zhendong's suggestion is practical and meaningful, and it can indeed be done!" The chief engineer of the Defense Work Committee laughed.

As for Gao Zhendong's suggestion of a resolution of 300 or even 200 lines, no one had any objection. Everyone knew that this resolution was enough to do many things.

Gao Zhendong didn't even need to say anything, as others had already analyzed everything. After all, no one is stupid.

After hearing what the chief engineer said, Gao Zhendong smiled and asked the comrade in charge of broadcasting: "Comrade, do you have confidence in this parameter?"

In fact, if there is enough time, Gao Zhendong has a lot of tricks to improve this parameter to a level that is roughly enough for watching TV, but since he doesn't have time, he will put it aside for now.

The comrades who were engaged in TV broadcasting thought and calculated for a long time before they said responsibly: "I can guarantee 200 lines and 2 frames, and try to achieve 200 lines and 4 frames!"

He also heard that compared with resolution, these big guys were more concerned about frame rate.

This comrade is very good at grasping the key points. Gao Zhendong smiled and said, "Okay, how long?"

He calculated for a while and said, "Guaranteed four months! Try to be ahead of schedule." Technical comrades are always steady. Gao Zhendong was very satisfied: "Okay, thank you then."

Hearing his words, the comrades from the Defense Work Committee and the Air Force looked at each other.

"But I hope to get a better working environment for the equipment. In addition to the necessary equipment, I hope that as much space as possible in this suite can be left for us." said the comrade in charge of broadcasting.

Gao Zhendong nodded: "That's no problem. You are the most important. Our comrades in guidance will assist you in completing your work, and those who work on the missile structure will also lean towards you as much as possible."

After that, Gao Zhendong pointed to the schematic diagram of the gliding kit and said, "You can arrange the antenna problem that you are most worried about here. After the vertical tail is popped up, pull an antenna between the head and the tail of the kit. This is your antenna. This size should be enough."

Gao Zhendong had thought about putting the antenna on the wing, but placing the antenna close to the conductor was pushing the limit, even with insulation. It would not work, so he decided to use a tilted antenna.

Before phased arrays matured, there were very strict requirements on the size of the antenna. I think making them a longer one would meet their requirements.

"Well, okay, okay."

"As for the power issue, we will use silver-zinc batteries this time to take care of your electricity as much as possible." Silver-zinc batteries may not be very good as rechargeable batteries, but they are still very good as disposable batteries. If you don't consider the price, they are stronger than lead-acid, cadmium-nickel, and nickel-metal hydride. They have high capacity and small size. Otherwise, early electric mines would not have used this thing.

This kit obviously doesn't take price into consideration.

The comrades at Chunlei Factory quickly wrote down these words and said, "Well, this thing uses silver-zinc batteries."

Gao Zhendong's promise made the comrades in charge of television broadcasting very happy, and it was basically a sure thing now.

Somewhere on the snowy plateau, some soldiers are training.

"How is it? Can you hold on?" Looking at a soldier's face and condition, his platoon leader asked him hurriedly.

"It's not a problem, I just have a bit of a headache, but I can still handle it." The soldier insisted, answering with some difficulty.

"Headache?" Looking at his breathing and complexion, the platoon leader gave the order.

"Two people, take him to the infirmary for oxygen."

He knew very well that this soldier would not even mention a normal headache and it would go away if he just endured it. But since he mentioned the headache, it meant that the situation was very serious. Considering his other conditions, he absolutely could not continue.

The soldier shook his head: "I'm fine, I can still hold on!"

"This is an order! There is still time for training. We have just come up from the southwestern plateau a few months ago. We will eventually adapt to the environment here, but you can't be impatient, do you understand?" The platoon leader gave orders while comforting them.

These are field troops transferred from the southwestern plateau. The southwestern plateau is not as high as here, but I think they will adapt faster than those in the plains.

Moreover, the southwest plateau is mountainous, and the troops stationed in these two provinces have advantages in mountain warfare. They can quickly connect and cooperate with the border defense forces that have long adapted to the local environment, and their equipment and training are more inclined to the goal of this time.

The value of the vast land and abundant resources has risen again.

At about the same time, the Snow Mountain Airport was under tight security.

In addition to the air-transported anti-aircraft guns, there are also some surface-to-air missiles.

Several commanders were waiting for something in the tower, chatting as they waited.

"With the anti-aircraft guns and short-range surface-to-air missiles modified from infrared air-to-air missiles, the innermost two layers of the airport's key air defense have been almost solved. Unfortunately, the radar medium- and high-altitude missiles can't reach them."

The infrared air-to-air missile is not used after being launched, but its reaction speed is greatly enhanced with the matching radar. It still has a range of 6 to 7 kilometers on the ground and a firing height of 3 kilometers. In addition, at a snowy mountain airport at an altitude of 3600 meters, the air defense effect is already quite good.

After Gao Zhendong and the Institute of Radiation Research developed the Thunderbolt-3, the institute was not idle. How could such a good thing only be used in the sky? It can be used in the sky and underground.

In the 60s, 80s and s, infrared missiles were rarely used as surface-to-air or ship-to-air missiles because they had a big problem: they could not hit the enemy head-on.

Even if the air defense is nine out of ten times effective, this air defense method can only be used after the fact and is too abstract, so it is rarely used as an air defense projectile.

Oh, what a coincidence, the Thunderbolt-3 can hit head-on! So it is logical to use it for close-range air defense and key point air defense. This thing is very useful after it is launched. Although the range is not far, it is better than the portable bomb with only half of its range. And one advantage of this thing is that it is not that big.

"The S-75 is too big, so there are indeed some difficulties. But don't worry too much. We have portable air defense missiles as an inner layer supplement, and radars and fighter jets as an outer layer of air defense. We will definitely be able to complete the airport defense mission." Another Air Force comrade replied.
