The development of air-to-air missiles has gone through several stages, the first of which is the need for fighter guidance.

This air-to-air missile is the biggest test for fighter pilots, because whoever slips away first will lose its guidance.

The second stage is that as long as the fighter radar locks on the target once and launches, it can be ignored.

Most of the air-to-air missiles of this period were equipped with active radar.

There is also a passive infrared mode, which is also a kind of emission after ignorance.

The missile will chase the opponent's infrared target signature, but this missile has proven to have a low hit rate.

It is not uncommon for missiles to be mounted on helicopters, and the Comanche can fit a two-meter-long missile and it is in the belly of the aircraft.

However, the range of air-to-air missiles is generally long, at least tens of kilometers, so loading air-to-air missiles on helicopters is a very bold innovation, at least at this stage.

What makes Liu Hai curious is what kind of radar this helicopter uses.

When many people watch air combat movies, they are curious about why the fighter jet is frantically pulled up by the missile lock.

That's because the fuel for missiles is limited, so that the fuel consumption of missiles can be maximized.

As soon as the fuel of the missile runs out, then the missile is also destroyed.

Liu Hai really wanted to go over and see, what type of air-to-air missile is it?

Because Liu Hai seems to remember the failure of the development of the Thunderbolt four-air-to-air missile.

Later, the Thunderbolt-5 missile was successfully developed.

But it's a pity that it is impossible for Liu Hai to get close, after all, the air-to-air missile that is being tested, how can it be possible to let Liu Hai get close, and if something goes wrong, who is it?

Liu Hai and the others came to the shooting range, which was the shooting range of the artillery.

Counter-battery radar positions are arranged at a distance of 5 km from the range.

A program is a program, and after the program is made, it needs to be actually debugged.

The distance of the radar antenna, the radar control vehicle has a distance of 30 meters, which is connected by a cable, of course, the distance of the cable connection can be increased, this is to protect the radar control vehicle, because there are also some anti-radiation missiles specifically for the radar in the back.

The radar antenna has been deployed, and the huge radar antenna is so conspicuous.

The radar control vehicle integrates a series of functions such as computer power generation and of course, and of course, the radar antenna can be towed.

The process of testing and debugging is very boring, that is, the distant range is first fired with various mortars, the radar side records the data, and then the coordinates of the artillery position are obtained.

Just take this coordinate and compare it with the coordinates of the artillery position in reality.

There must be errors, and this cannot be without, and the farther the distance, the greater the error.

Of course, it is much more accurate for the detection of the artillery position of the mortar, because the velocity of the mortar shell is low.

The temperature outside is still very cold, but the temperature inside the command vehicle is constant.

Liu Hai is not the only one here, but several leaders are also watching.

Liu Hai, on his side, was also responsible for directing the artillery firing of the artillery positions.

Nine seconds after the artillery position was fired, Liu Hai got the data of the artillery position.

The artillery radar designed by Liu Hai does not require a person to manually enter elevation data, and the Simberlin radar needs to manually enter 8-bit data and then derive the address of the artillery position.

"Error 6 meters!" These leaders were also surprised to see the data compared between the two sides.

For artillery, an error of 6 meters is nothing at all, and a random howitzer will not be more than this damage area, and as long as the opponent's artillery position is found, it must be dozens or hundreds of shells, directly covered.

Not to mention the error of 6 meters, even the error of 16 meters is not bad.

Of course, for the bangs, the error of 6 meters is relatively large, but there is no comparison, because there are too many precision-guided weapons when the bangs cross.

And it's only 5 kilometers, and the distance is 6 meters wrong.

In 2020, some missiles did not have an error of 6 meters, not to mention various precision weapons.

Of course, Liu Hai also knows that the weapons and equipment at this stage basically rely on quantity to win, whether it is artillery shells or rockets.

"How many shells can be saved with this radar!" These leaders are all military leaders, and of course they know that with the data coordinates provided by this radar.

It can save a lot of shells, and in the past it took a dozen guns to fire two or three rounds, but now with specific data, one shot each of a dozen guns is enough.

These leaders were more excited, but Liu Hai had a breezy look.

The leaders all secretly praised in their hearts: Comrade Xiao Liu is calm and calm.

If Liu Hai knew that he would be praised by the leader like this, he would probably cry and laugh, because for Liu Hai, there is nothing surprising that the error of 6 meters is, because he has seen more accurate weapons.

Then another test was carried out, 60 mortars and 80 mortars took turns.

The range is also gradually increasing, of course, to the bitterness of the soldiers who fired the artillery, because these soldiers have to run around with mortars.

Go to one place and shoot two shells, then report your own coordinates, and then run quickly.

When these soldiers ran around with mortars.

In a certain unit on the plateau, a group of soldiers are conducting target shooting training.

The soldiers were armed with a variety of weapons, including AK47 automatic rifles, bald eagle carbines, and early Mosin Nagant rifles.

In addition to the K47 automatic rifle, the carbine and the Mosin Nagant rifle all have a triple lens on them.

These soldiers are all from the southwest, as well as from the plateau.

In addition to training, the soldiers were learning another language, but it was enough to learn a few of the other language.

This language is partially similar to the highland language, but the soldiers did not know which country's language it was.

The plateau is still very cold, and these target soldiers are still quite excited, although the guys in their hands are old, but after all, they can shoot bullets.

As a soldier, as long as you can shoot, as long as you have a gun in your hand, you like it very much, and the carbine and Mosingana rifle are equipped with triple lenses, which makes them more energetic.

In addition to target training, they also have to train mortars, RPGs, and the most surprising thing for these soldiers is that they actually have to take a helicopter for rappelling training.

There were even some antique infantry guns that came out, and although they were said to be antiques, the shells still made the artillerymen very excited.

As for the most basic civil engineering training, now is not the time.

These soldiers train during the day and at night for language training.

Although these soldiers did not understand the reason for the training, most of them knew that there must have been action, otherwise how could they have opened up so many things for themselves to build.

It's just that so much hodgepodge of equipment makes the soldiers a little puzzled, isn't there any standardization and unification in the team? It's about reducing logistical pressure.

What's the point of taking out so much of the old stuff now?

According to Liu Hai's suggestion, the higher authorities did not contact anyone on Xijin's side, because they were not sure if there were any people from the king's side over there.

However, the railway department has mobilized capable forces to prepare to build a road from Karitse to Yadong.

The reason why the railway department came to build this road is because the shield machine is under the jurisdiction of the railway department.

The invention of the shield machine has brought great changes to our country over the years, especially when building tunnels, and the probability of encountering dangers is getting lower and lower.

In the past, tunnels were built by manual blasting, which was quite dangerous.

And artificial blasting will also cause certain damage to the mountain, after the shield machine, the safety factor is greatly improved, the shield machine goes in front, and the module is installed in the back.

Of course, now the module has also made a lot of improvements, using high-strength concrete in some high-strength places, and even adding a series of other things such as glass fiber to increase strength.

However, the improvement of the shield machine is still relatively slow, and the current shield machine is basically hydraulic and mechanical control, and the electronic control is not very realistic.

Hydraulic and mechanical control is more needed.

With electrified control, a smaller number of workers are required.

After so many years of development, the railway department has cultivated a mature team of shield machines.

The railway department has also set up its own research institute to optimize and upgrade all aspects of the shield machine.

Bangs test counter-battery radar data, the program is optimized based on the data of the tests.

At a distance of 25 km, the error on the mortar position reached more than 20 meters, and on average it reached 23 meters.

This data is relatively normal in the eyes of Liu Hai, and the error of the last 5 kilometers was 6 meters.

Then there are howitzers, which have a relatively large detection error for low-trajectory howitzers.

Although Liu Hai was a little dissatisfied, the onlookers were quite satisfied.

Because in general, the artillerymen will shoot one shell first to correct the position.

At this time, the counter-battery radar gets the coordinates of the other side.

Maybe the artillery positions of the opposing side have not yet begun to fire, and the shells from this side will shoot out and fall on the artillery positions of the opposing side.

As for the error of more than 30 kilometers and 20 meters, this is also called an error?

To know how far 30 km is, most of the howitzers in the 70s had a range of only twenty or thirty km.

That is, 30 km basically reaches the firing limit of howitzers, and the counter-battery radar is quite safe at this distance.

The key is the bang, an anti-battery radar, which can also be anti-rocket.

This made several leaders very excited, in fact, the counter-battery radar of Liu Hai can also detect missiles.

As long as the data can be detected within 30 kilometers.

When Liu Hai tested the counter-battery radar data and debugged it, the relevant drawings and procedures were sent to the relevant departments for study.

This time, the bangs were only designed and programmed, and the rest was completely left to other departments, from radar antennas to computer circuit boards.

So it is quite simple for the higher authorities to want to copy a counter-battery radar.

Of course, the cost of the current counter-battery radar is too high, first of all, the electrical scanning phased array radar antenna, which is almost entirely hand-built in the laboratory.

In addition, there are various chips on the computer, and the superior departments have attached great importance to the chips, because a large number of chips are used in the three-axis CNC machine tools designed by Bang Hai.

The price of the purchased chips is too high, and the cost is too high for large-scale use, so the higher-level departments set up relevant departments as early as last year to develop and manufacture our own chips.

Today's semiconductors involve computers, which are more expensive than gold, and there are many chips in a computer cabinet on the radar car.

Because today's computers use a lot of precious metal gold.

Now the pins of the chip are basically gold, even the circuit board is gold, and the wires are made of silver.

As for why the use of gold and silver is to improve the life of the entire computer, the military is to ensure its stability.

Even in modern military equipment, precious metals are used a lot.

Gold is originally a hard currency, and then it is not cheap to make a finished product through a complex process, of course, Liu Hai has this capital to take so many chips to pile up materials.

Now a state-of-the-art 8080 chip costs $360 a piece, and of course the performance is 20 times higher than that of the 4004 chip.

You must know that at this time, the average annual income of the workers in the Bald Eagle family is about 3,000 US dollars.

One chip is equivalent to a month's salary for a bald eagle worker, and he can't afford it.

Therefore, it is really burning money to engage in computers now, and the speed of updating and iteration of chips from now on is also accelerating.

The development of chips is very rapid, from the birth of 4004 to 8080 only used for a few years, the development of chips has since embarked on the fast lane, we can enter the field of chip development at this stage, or can catch up.

In 1974, the sales of 8080 chips skyrocketed and millions of pieces were sold, so the price also dropped from $360 to $35.

That is to say, if you bought a $360 chip in the second half of this year, you will lose 90% of the cost price alone.

Of course, in the future, the chip will only sell for three dollars.

However, for the chip field, Liu Hai is confident that he can catch up with foreign countries, and he wants to have a direction, a direction, an application, and then it is nothing more than burning money.

Of course, the notch counter-battery radar can also do a lot of things, and it can also be used for artillery calibration, ground and coastal surveillance, helicopter tracking and control, rapid geodesy, and weather balloon tracking.

Although the test and debugging have not yet been completed, the higher authorities have already rushed to the ground to start producing this counter-artillery radar.

At the end of March 1974, Rover Film Company successfully acquired Luen Mei Film Company, which is one of the eight major Hollywood film companies, Liu Hai became a shareholder of two people, Mr. Jack invested 4.9%, Mr. Z invested 4.9%, and Liu Hai's personal contribution was only 5 million US dollars, that is, 4.9% of the shares, worth 2.5 million US dollars.

Several major Hollywood studios have been sluggish in recent years, because a large piece of the cake has been cut by Rover.

The entire film market plate is so big, and Rover Films uses Transformers Kung Fu Panda, online and offline alliances, online movies, and offline toy playgrounds to beat other film companies unwanted.

Therefore, only one or two of the major film companies can guarantee profits, and the rest lose money every year.

As a shareholder, there is no need to keep a loss-making business in your hands.

As for why the share is 4.9%, it is because of the principle of public announcement, and 5% is a threshold.

In other words, Liu Hai's shareholding is actually 9.8%, but if you buy shares as two people, you don't need to make an announcement.

His Majesty also holds 10% of the shares of the film company, and the rest is owned by Rover.

This dealer hit Liu Hai with the idea again, and wanted Liu Hai to write a script and turn Luen Mei Company into a profit.

Of course, Bangs is obliged, so every night when he comes home, he goes into the aircraft carrier space to see what movies are easier to make money.

For Liu Hai, copying the script may only take a few hours, but the income may reach tens of millions of dollars, so why not?
