The Boeing 707 aerial tanker is actually a large aerial tanker improved by the US Air Force KC-135 large aerial tanker, an improved US C-135 military transport aircraft. It has a wingspan of 3988 meters, a length of 4153 meters, an altitude of 127 meters, a maximum cruising speed of 9000 meters is 982 kilometers per hour, a ceiling of 15240 kilometers, and a range of 5552 kilometers.

The reason why this large aerial refueling aircraft has become a nurse of the US Air Force is not only because it can refuel four fighter jets at the same time, but also because its maximum fuel transport capacity reaches 90 tons, and the maximum take-off weight of the entire aircraft reaches 146 tons! It adopts a telescopic casing aerial refueling system, and the refueling operation adjustment distance is 58 meters, refueling four fighter jets within a space range of 54 degrees up and down and 30 degrees horizontally!

This is the longest-serving military aerial refueling aircraft in the world.

Liu Yijiu himself did not expect to fool Iran into flying such an aerial refueling aircraft that the republic could not get to China.

Liu Yijiu was a little excited to see that he had completely landed on the runway of Taiping Temple Airport.

This thing is much stronger than the Hongliu Master, who has carried the banner of the Republic for more than half a century.

The refueling machine developed by the Republic on the basis of H-6, is called H-6, with a maximum take-off weight of 758 tons and a maximum oil load capacity of 37 tons. The only 185 tons can be used to transport oil to fighter jets...

Such a nurse simply lacks milk, and the child cannot get enough, so he naturally cannot run far. Even if he improves countless times later, these congenital defects cannot be solved, and the entire plane is too small.

You can only refuel two fighter jets at a time, and at most six J-8 fighter jets can be refueled.

When the Republic's Air Force used tankers, a typical formation was two six-mistresses and twelve eighth masters. Then the 12 eighth masters were divided into three four-mistress formations, and three air guard circles were established within 1,200 kilometers to protect the nurse from being destroyed by the enemy.

You should know that the nurses of fighter jets are basically without attack power, and they are full of aviation fuel. When attacked, they will easily become a pile of garbage and fall down.

Without the nurse, the eighth master's combat radius is only more than 700 kilometers...

Of course, with a nurse, it only expanded by 1,200 kilometers, increasing some time to stagnate.

Originally, Liu Yijiu didn't think of this problem at all. After all, the problem of aerial refueling aircraft was not within his consideration. In their era, fighter jets were reduced in mass due to the large-scale use of graphene, and the combustion efficiency of the new aircraft engine reached a level that could not be looked up to in this era. That range could even circle the earth...

Therefore, he did not consider the issue of aerial refueling engines.

Moreover, there is no platform suitable for changing to an aerial refueling machine in China.

Sixth Master carried the banner of more than half a century. In the end, the Republic tried hard to increase the range of the fighter jets because of the lack of milk from this nurse, and finally cut off the arrangement. The fighter jets were only able to refuel directly at the airport, and it was not a problem to run around the world. Or it also had a lot to do with Yunshi falling behind after the success of Yunshi and Yunshi dismounting.

Large aircraft have always been a pain in the hearts of the Republic's aviation science and technology workers. Until the Republic's aviation technology made breakthrough progress in the late 1950s - the emergence of super aerospace fighter jets!

In 1997, the first aerial refueling group of the Republic was established...

For the Chinese Air Force, the combat radius of fighter jets is small, and the nurse in the air is not strong, and there is too little milk. This is a huge sadness.

Liu Yijiu has arrived in this era. He has no way to let the aerospace fighter appear when such various foundations are just beginning, and he can't understand them completely. Therefore, he found ways to make the Republic's air force stronger.

Only by having a strong air force can air supremacy be guaranteed.

It is further related to sea control and ensuring the security of the motherland!

"Wow, this plane is so big..." Li Rui had never seen such a big plane.

Even pictures are rarely seen. The Sixth Master of the Republic is already very large for her, but she didn't expect that there would be a larger plane than Sixth Master!

"Yes, this aircraft is too big. If we can understand the technology thoroughly and then transform the J-8, we can completely protect all our territorial waters and airspace..." Even Sun Daoqian, a person who specializes in transport aircraft and bombers, had to sigh at the size of this aircraft when he saw the physical objects!

It's more than ten meters high, and it's too small for people to stand in front!

Liu Yijiu didn't think this thing was too huge. The space plane used by the Republic to launch spacecraft when it was building the moon base. If it were here, it would scare them to death!

Not to mention anything else, even the An-225 that appeared in the 1980s was far more than these aircraft!

I hope that because of his arrival, the Russians will produce more of these huge aircraft that had not been surpassed before the 1940s. They will steal it back and install nuclear power. They will be completely a mobile fortress in the air. If they are loaded with bombs...

That thing is eighteen meters high, which is as high as a six-story building! Its length is twice that of the kc-135 that is slowing down, and its wingspan is also twice as high!

For Liu Yijiu, the air refueling aircraft that is about to be eliminated by the US Air Force may not be eliminated, but the US has a more abundant milk KC-10.

This thing is just right to match the fighter jets with double three indicators they are currently designing.

For a small plane like Eighth Master, you can only go to the Sixth Master to feed them. Of course, if this nurse is made, she can completely let a group of Eighth Masters who have more than twenty aircraft go to the air to play. At that time, half of them will go out to beat people and half will keep them for protection...

"We must make this plane by ourselves!" Xia Fei was jealous when he saw this giant.

As a country's air force commander, his aircraft can only fight within the combat radius, and even the most basic airspace cannot be fully defended. This is simply a huge shame! There is no air force base in the South China Sea, and it is a distance of 1,000 kilometers from the South China Sea Island to the most remote place in the Xisha Islands!

"Yes, it must be done. Xiao Liu did a good job this time!" Long Yaohua looked at the huge plane that had completely stopped, looked up and murmured.

"If our logistics company has this, we don't have to worry about our air force being unable to fully patrol our seas because of the small combat radius!" Li Yunlong said gritted his teeth, then turned his head and said to Sun Daogan, who looked at the giant in front of him with affectionate expressions, "Xiao Sun, give me a message, when can I copy it! I don't need to do it from the base of Yunliu, so let's start with this!"

Sun Daogan didn't expect that when he saw this plane just now, and he didn't even figure out how many techniques they couldn't grasp inside, Li Yunlong began to ask him when he could imitate it.

He knows better than anyone else about Qin Fei's situation. The technology of bass engine has been introduced for a long time, and Qin Fei has not digested it until now.

The J-8ii has not been used to the Chinese mind until now!

"We can be responsible for the avionics system, and we can also bear the engine..." This time, Liu Yijiu did not refuse.

Anyway, they have long been studying the avionics system of fighter jets.

If they win the most difficult part, only they have the strength to win!

Qin Fei should have nothing to say.

Moreover, Liu Yijiu also made two of the most profitable parts. The aircraft engine is related to whether the aircraft can fly in the sky and various data during flight, and also to the various performances of the aircraft.

This is the heart!

The highest profit means the highest technical content and the greatest technical difficulty.

"In six years, we should be able to provide engines for large transport aircraft! If our turbofan ten projects make breakthrough progress, it may not take that long!"

"Six years! Chief, please give us six years. As long as Director Liu can provide us with avionics and power systems, we will definitely be able to manufacture such an aircraft by ourselves!" Sun Daogan said gritting his teeth.

The technical content of f14 can even be said to be higher than the huge aircraft in front of you!

Liu Yijiu dared to guarantee that he could imitate the American heavy fighter F14 in five years. Why didn’t he guarantee that the most core technology would be undertaken by the Ninth Academy?

"Okay, I'll give you six years to all major aircraft factories, and you will allocate the personnel, and we will satisfy you to the greatest extent..." Li Yunlong also said proudly.

When Liu Yijiu heard this, he was anxious. He couldn't shoot himself in the foot!

The project team of Yunshi must not let go.

Moreover, he wanted to dig people from other planes.

Qin Fei is engaged in transport aircraft and bombers. His first choice is the Yun-10 team, which has completely stopped the project research. Liu Yijiu has already agreed with Ma Fengshan Ma Lao to not go to the funding. The Ninth Academy will fully accept the large aircraft project and their entire team. No one can be left behind. Just pack up their things and wait with peace of mind.

At that time, just divide them into part of the territory at 611.

The current Rongcheng is not as crowded as decades later.

"Chief, this doesn't work. I still need people. They have all taken away people. What can I do? Otherwise, I'll keep it in my own hands!" He immediately raised an objection. (To be continued.)

ps: The eighth update, it was more than an hour late, and it was finally updated. This is already the limit, and it is not easy to serve the wife to change the diapers to the child...

I will continue to go crazy tomorrow, and it is possible that I will still be seven updates!
Chapter completed!
