Because of this, looking at Song Tianming, who was multitasking but not chaotic, Jin Bin's heart unconsciously changed from doubt to amazement, and from exclamation to envy, and finally his eyes lit up and began to look at every part of this carriage, from the ticking radio station to the distribution of the line; From the allocation of personnel, to the composition of the radar system.

Jin Bin is like an explorer who inadvertently broke into a treasure, even if he can't take everything here, he has to keep this place in his mind carefully, because he knows that this set of equipment looks inconspicuous, but once it works, it will increase its combat effectiveness by several levels.

It is important to know that the Soviet Union summed up a set of effective but extremely complicated air defense tactics for fighters based on the experience of the Soviet-German war, that is, to guide the air force to fight the enemy in air based on the real-time detection parameters of ground radar.

The "MiG corridor" north of Pyongyang looks like the MiG-15 is making a big show in the sky, but behind it is an impregnable air defense line that has only been compiled by nearly 100 ground guidance equipment.

However, the problem is that the ground guidance station in the usual sense is a large size and a large number of fixed equipment, and only a unit of the level of the air base can accommodate and use such equipment, but at present, the equipment used by the Chinese army is compressed to only a few carriages.

It can be said that as long as you have this set of equipment, within the combat radius of your own fighters, it is equivalent to having an on-call aviation umbrella, and it is unusually convenient and fast for both attack and defense.

This is nothing less than a rare artifact on the Korean battlefield where the US air force is raging, and its tactical value and strategic significance are simply immeasurable.

In that case, why is the Korean People's Army not equipped with several sets?

With this mentality, Jin Bin looked more carefully, and from time to time he would ask the volunteer officers and soldiers next to him for a few words.

It is nothing more than a series of several sets of mature equipment, and the technical difficulty is not high, the Korean People's Army not only has these equipment, but even in terms of technical level, it is a large cut higher than the Chinese army, of course, even if it can't catch up, it doesn't matter, where does the big brother of the Soviet Union have good things, as long as he runs over and cries and cries poor, he can get it by showing loyalty.

So Kim Bin breathed a long sigh of relief, and secretly decided to wait for the train crew of the Volunteer Army to go south, and immediately report to the Central Committee of the DPRK, and immediately start to set up a North Korea-like train ground-to-air guidance system!

"I didn't expect you to be a knowledgeable person! How's it going, how much have you learned? ”

"Almost seven-seven-eighty-eight!"

Just when Kim Bin was thinking about the train anti-aircraft artillery system in front of him, and considering the words of reporting to the North Korean leader, a cold question came to his ears, and Kim Bin responded casually without thinking about it, but as soon as these words came out, Kim Bin regretted it in his heart.

But it was really impossible to take it back, so he could only turn his head hard, and then he saw that Song Tianming, who didn't know when he would end his busyness, was looking at him with a smile: "Seven, seven, eight, eight? Not bad! It's just ......"

Song Tianming nodded meaningfully, but paused as he spoke, then looked around at the equipment in the carriage, raised his eyebrows slightly, and said arrogantly: "It's just that we have a saying in China, that the meat of the bun is not on the folds, and the goods in the stomach are not on the mouth. ”

Jin Bin, who was broken by Song Tianming's words and stole learning, was ashamed, he didn't even mean to blush, the Soviet Union is the big brother, China is the second brother, and the little brother of North Korea has something to worry about learning from his brothers, so seeing Song Tianming's pick, Jin Bin was ready to get off the donkey and directly admit his behavior.

However, before he could speak, Song Tianming's meaningful words made him stunned, could it be that this set of equipment is not as simple as it seems? It's impossible, one by one, he has carefully looked at each one, it's not a big deal, to say special, it's nothing more than a few unique interfaces, but it's not a big deal.

Seeing Jin Bin looking at himself with a stunned face, Song Tianming couldn't help but smile secretly in his heart, these things look simple on the surface, but several important parts in them have been transformed by Bai Yi himself, otherwise, how to guide the MiG-15 to fight with the 20-kilometer detection range of the Song-9A fire control radar?

It is not yet necessary to rearrange the signal receiving and transmitting devices in the interior, expand its detection capability to 80 kilometers, and use two radars to form a two-coordinate aviation parameter detection network, which can barely meet the basic requirements of the MiG-15 to guide operations.

The air-ground communication radio looks ordinary, but the circuit board inside has been changed beyond recognition by Bai Yi, whether it is distance, efficiency or confidentiality, I don't know how many times higher than before, and the frequency channel must be consistent with the MiG-15 communication system, otherwise how to carry out air-ground communication?

There is also the aviation map on the desktop, which is comparable to a ghost drawing, which is the core of fighter guidance, if there is no detailed track, incomparably clear route and complex parameter comparison table, even if Song Tianming catches the enemy plane from the radar, it is impossible to accurately guide his own fighter.

In the end, it is his own, driving this set of equipment is really not a human job, not only to understand the principle, but more importantly, to guide, while according to the radar indication coordinates with reference to the aviation map for rapid calculation, completely relying on manual real-time calculation, even if the parameter comparison table has been extremely detailed, it is also a job that can tire people to the liver.

Therefore, this guide can be said to be the top priority of the whole set of equipment, Song Tianming was tortured by Bai Yi's hellish training, if it were someone else, it is estimated that he would have been in a hurry and messed up!

Where did Jin Bin know that there were so many doorways inside, and when he heard Song Tianming casually say the details of a few equipment, he was stunned, and after a long time, he asked carelessly: "Comrade Tianming, is this ...... This...... Did you really make it yourself? ”

"Of course! Otherwise, who have you ever seen who can play this big dick like this? Forehead...... Not to mention, the American devils are here again, 'drunkards', 'drunkards', in the direction of ten o'clock, there are about four fighters, the altitude is 1250, and the speed is ...... 214, Route 406! ”

"Leave it to us!"

Lukotsev answered, immediately poured a sip of wine, and yelled at the intercom: "Chinese boys, follow me, see how your master blows up those Yankees......"

As he spoke, Lukotsev moved the joystick and pounced in the direction of ten o'clock, and the five fighters piloted by the Chinese Air Force pilots behind him quickly followed, like young eagles learning to hunt, killing a new batch of prey......
