Chi County.

At night,

The sound of a muffled propeller streaked across the sky.

On the ground, inside the devil's stronghold, Suzuki was stunned.

Long

He muttered to himself.

"It's really airlifted at night."

Even if it has been speculated through various evidences, the Eighth Route Army had airplanes, and used airplanes to carry out night transportation, and to the north to evaluate the transportation of silver dollars, Xinhua Bao and other newspapers.

In addition, the talents of the Northern Assessment were transported by plane to the so-called base area of Tuba Road.

But Suzuki always felt incredulous.

He knew that the forces behind the Dirt Eight Road were very technically capable.

The Eighth Route Army had no problem putting together a few pilots.

But long-distance air transport at night.

How do they navigate accurately?

At this time, when he heard the voice, he realized that it was true.

"Yaga"

Suzuki Fanji spit out a Yaga, but there was a flash of light in his eyes.

Now that the means of transportation of the Dirt Eight Road have been found, it is natural to cut it off.

Compared with the ground transportation channel, although the air transport is convenient and fast, once discovered, it is also easier to cut off, especially this kind of air transport through the enemy's controlled area.

Really think that the empire does not have planes?

However, the vastness of the air, coupled with the limited vision at night, he needs to investigate the flight path and flight time of the unearthed eight-way aircraft, otherwise the army aviation will not be able to accurately send planes to intercept it.

···

It's August '40.

At this time, the Pacific War had not yet begun, and although the contradictions between the United States and Japan were becoming increasingly acute, they had not yet broken out, and the two countries were still bustling with trade on the surface, with a monthly transaction volume of more than $100 million.

Every day, a shipload of supplies departs from the mainland of the United States and is transported to the mainland of the devil.

The devil's strength is at its peak.

The local petty fights in North China and the loss of several wings can only be regarded as flesh wounds for the devils.

Following.

An investigation report involving the entire southern Hebei, Taihang, and Taiyue surrounding devil brigade-level garrisons was submitted to Suzuki Fan's second-hand middle school.

"The plane took off from the Taiyue Mountains."

"Passing through the Taihang Mountains, the southern Hebei region, and even passing near Shimen, we finally arrived at Beiping."

With the orders of the North China Front and the assistance of the General Staff, Suzuki Fanji sorted out and summarized the intelligence data of all the garrisons in North China, and easily analyzed the flight path of the Yun-5.

"Sure enough, it's the Taiyue Mountains."

Suzuki took a deep breath.

Although the 27th Division returned without any clues, it was already certain that all the materials obtained by Tubalu came from the Taiyue Mountains.

He had speculated before,

If there is an airplane on Tuba Road, it must take off from the Taiyue Mountains.

It's just...

"Where is their airport?"

Suzuki didn't understand.

Before the 27th Division swept the Taiyue Mountains, although the First Army Air Wing was limited by the shortage of ammunition and fuel, the aviation bombing resources needed to be prioritized to supply the bombing mission of the mountain city and put pressure on the preserved fruits.

Plus the poor effect of bombing in the mountains.

There has never been a large-scale bombardment of the Taiyue Mountains.

But aerial reconnaissance has also been maintained.

As long as the weather permits, two reconnaissance planes will be launched every day to conduct a comprehensive reconnaissance of the Taiyue Mountains.

Since there was no air defense on the Tuba Road in the Taiyue Mountains, the reconnaissance planes flew almost at an altitude of less than 500 meters.

At this height, coupled with the special high section, the intelligence department of the First Army, the intelligence department of the North China Front, and the ground reconnaissance intelligence personnel sent out, even in the mountainous areas, it is impossible for an airfield to avoid aerial reconnaissance.

The airfield targets are large, very obvious targets for reconnaissance, and it is almost impossible to hide.

"Submit the information to the North China Front Command."

Although he was puzzled, Suzuki quickly handed over the information to the headquarters.

···

"The plane took off from the Taiyue Mountains."

"Passing through the Taihang Mountains, the southern Hebei region, and even passing near Shimen, we finally arrived at Beiping."

Command of the North China Front.

After receiving the news, Tada Jun was overjoyed and immediately transferred the information to the major general directly under the aviation command - Ghana Shunzheng.

At this point,

Garner Shunmasa was chatting with his old friend, his old subordinates, the captain of the First Army Flying Wing who had come to Beiping to participate in the military conference, and Sakashita Baoxiong.

After receiving the news, the two devil flight commanders were not happy at all.

"No airfield found."

"Night flight."

The two looked at each other, their eyes solemn.

As flight officers, the two are better versed in the strengths and weaknesses of aircraft.

According to the information,

The planes of the Eighth Route Army flew at an altitude of more than 2,000 meters the entire time, and at this altitude, all the anti-aircraft guns equipped with the North China Front were powerless and could only rely on aircraft to intercept them.

But in North China, the Locust Army currently does not have aircraft that can be used for night operations.

According to the report of the Beibalu Organ Section, at present, the police and the gendarmerie have still not found the location where the Tuba Road plane landed, and it seems that in the Bei Assessment, the landing position of the Tubalu plane was temporarily decided and can be changed at will.

This means that

Even if they knew the flight time and route of the Tubalu aircraft, the locust army could not do anything.

"They should have some kind of positioning and navigation."

Sakashita presumed hokuma.

It is not difficult to derive this conclusion, it is even very simple.

Night flight, navigation is the key, but also the key, the locust army has not been able to solve the problem of night navigation so far, whether it is using radio navigation, or coordinate point navigation, it is easy to get lost.

In the past month, the Tuba Road has flown 15 waves, and the locust army investigation has not found any abnormalities, which can probably show that there are no problems with the Tuba Road aircraft in these 15 waves of transportation.

"We need night fighters."

Sakashita looked at his boss, Major General Junmasa Garner.

The North China Front did not have night fighters,

Although there is no one on the mainland, he is just a big Zuo, maybe he doesn't know this kind of confidential information,

"I'll report to the local community."

Garner frowned.

As far as he knew, the Reich did not have a night fighter in service, and there was not even a plan to study a night fighter.

As a senior major general, a technical officer who had participated in the development of a variety of fighters, bombers, and transport aircraft, he did not know, which means that there really is none.

Without night fighters, how can you intercept enemy transports at night?

"It takes too long to mobilize fighter jets from home."

"Let's start with navigation."

"Whatever they do to navigate accurately at night, it's necessarily by radio, and we can find them by technical means."

Garner said in passing.

Radios are great for concealment, but they are also very easy to expose.

"Hey."

Sakashita had a hunch that this would not be so simple, after all, the forces behind Tsuchihachi were notoriously technologically advanced.

But there is no other way at the moment.

···

"Report."

Night.

Headquarters of the Eighth Route Army.

A copy of the information was submitted to the Deputy General Staff:

"According to intelligence, the devils have recently collected the logs of the devil's garrisons in Taihang, Taiyue, southern Hebei, etc., almost the entire North China region."

"The focus was on asking if there were planes passing by during the night, and the time and route were investigated in detail."

Information!

Information!

With the abundance of funds, the enhancement of military strength, and the enhancement of influence, the intelligence construction that the headquarters has focused on has finally yielded results.

As soon as the devil collected information on his front foot, the headquarters here got the news.

Of course, there is a big reason why it can be so fast and detailed and accurate, that is, the devil does not hide it, and of course, it is almost impossible to cover up such a huge action.

"It seems that the devils are planning to attack our air transport corridors."

The division commander speculated.

It was thanks to the successive waves of transport planes every two days that the headquarters was able to transport funds to Beiping, Taiyuan, Yangquan, and even Jinling, as well as to transport and transfer personnel.

The local talent has been replenished.

Comrades lurking in various places have also been replenished with funds.

"Do they have a night fighter?"

The Deputy General Staff sneered.

The transport aircraft always flew at an altitude of 3,000 meters and remained at night.

He asked pilots with experience in fighter flights.

Even if there is a moon, the vision in the sky at night is very poor, the distance is a little farther, and it is impossible to see the plane of the Tianshan Mountains at all, although the biplane has poor maneuverability, but the maneuverability of the devil plane is not much better, and it is easy to dodge it through low altitude.

Flying at ultra-low altitude at night, it is almost impossible to find.

The low-altitude performance of its own transport aircraft can seem to be excellent.

There are navigation coordinates, and there will be no trek.

Unless, the devils have night fighters.

But the information behind Li Yunlong is very clear, the devil doesn't talk about fighter jets, and he doesn't even have a plan to study night fighters.

"The devil is probably going to attack our navigation equipment."

Deputy General Staff looked at the map.

This air transport line has three weaknesses.

One is the take-off phase.

However, the airfield is in the Taiyue Mountains, where the 386th Brigade is stationed and the Independent Regiment is also there, and it is the base area with the strongest defense and control of the troops.

The hangar is also in the mountain, and the take-off runway is actually a road.

Extremely concealed.

The second weakness is the landing position.

This point is the most dangerous, and in order to ensure the safety of landing, the General Headquarters directly dispatches a special commissioner from the General Staff Headquarters to take charge of the landing position whenever there is a landing point for the aircraft's transportation line.

Fortunately, with the abundance of funds, the latent forces everywhere are also increasing, and the landing position can be transferred at any time, which can temporarily ensure the safety of landing.

The third point is the navigation equipment.

The navigator the same size as the knapsack walkie-talkie, combined with the walkie-talkie that can communicate at a distance of 30 or 40 kilometers, ensures that the transport aircraft will not yaw and can accurately transport the cargo to the destination at night.

But this navigation line is also the most vulnerable to attack.

Although the walkie-talkie and navigator are only more than 20 catties, in order to ensure the navigation and communication distance, the gain antenna is dozens of kilograms, nearly ten meters high, and the target is large, which is easy to find.

Ground navigation stations are also easy to spot by devils.

"We need to strengthen the security of navigation stations and communication lines."

The boss gave the order.
