Heavy fighters generally use double engines and large thrusters, and some take-off weight will exceed 20 tons. With a large body, this fighter has sufficient space, so it has good load range performance, large bomb load, large radar caliber, perfect avionics equipment, ample body space and great improvement potential. The advantages are in all aspects, under the same technical level, It is better than light aircraft in almost all performance aspects.

In contrast, the light aircraft uses a single engine, the body is limited, the fuel carried is limited, the empty time is short, the range is small, at the same time, the body is small, and the radar caliber that can be accommodated in front is small. As a result, its radar detection performance is low.

It can be said that compared with light machines, heavy machines have all-round advantages. The only disadvantage is that they are expensive!

Only rich countries can be equipped with heavy aircraft. In later generations, the Han country adopted the Su-27 as the main air control fighter, because only this fighter can protect the sky of the motherland.

At present, all kinds of aircraft in the Han Dynasty, from the J-5 to the J-7, belong to single engine light aircraft. Only the J-8 can be regarded as a medium-sized aircraft, if it is not divided into interceptors.

The Han Dynasty was short of heavy machinery.

Now, with the ability, when you go back, get back the Su-27, F-15 and the male cat for technicians to study!

Qin Guan had such an idea in his mind that he wanted to improve his country's weapon development level. However, he didn't know what else he had overlooked.

This neglected thing is also very important.

Absorbing more mental power can improve the upper limit of mental points. However, the country now needs not only weapon samples, but also various processing equipment. Those advanced machine tools can also be exchanged from the machine tool cemetery of future generations. However, simply absorbing mental power cannot unlock the new functions of the system.

In Qin Guan's sleep, all kinds of thoughts were constantly coming out.

Xiang Jing in front is driving steadily. Although she has become a driver for Qin Guan, Xiang Jing is also willing to go to Chen Yutong's house this time. She has a good harvest.

What benefits did Qin Guan get from it? Qin Guan stared at the painting for so long. What did he get? Xiang Jing doesn't know. She only knows that Qin Guan has more and more fans.

The lamppost lit up the road ahead. After turning the corner, we came to the front of a bridge.

This is a stone bridge with a long history. The stone lion at the end of the bridge looks this way and opens his mouth as if he wants to eat someone.

The motorcycle ahead was about to reach the bridge, but at this time, the motorcycle stopped slowly.

"What part are you?" asked the soldier in front.

At the head of the bridge, several soldiers are already standing guard. Although they are wearing the same military uniform, they have different shoulder badges and different weapons in their hands.

"An army of the Second Artillery Corps was ordered to block the bridgehead. Please wait patiently." said the other side.

Second artillery? Hearing this, the soldiers on the motorcycle immediately understood: "yes, we are here, waiting for you to pass first."

Two motorcycles, holding 212 in the middle, waited at the end of the bridge. They turned off the fire and looked opposite.

Trucks are rumbling by.

"What's the matter? What happened?" asked Qin Guan.

The car kept bumping and moving, but Qin Guan slept very well. Now, the car stopped, but Qin Guan woke up.

Qin Guan rubbed his eyes and looked at the road ahead. There were so many lights. Should it be a team in the transition?

In this era, apart from the army, there were few vehicles moving together. Qin Guan lay down in front of the window, looked at it and asked questions at the same time.

"It's an army of the Second Artillery Corps." Xiang Jing replied, "let's make way now and let's go when they leave."

Second artillery? Hearing the news, Qin Guan came to the spirit.

Qin Guan had the most contact with the army, the air force only recently, and the Navy and the Second Artillery had not been in contact. Among them, the second artillery is the most mysterious.

The second artillery, by name, seems to be a subordinate branch of the artillery. In fact, it operates not ordinary guns, but demons and ballistic missiles from hell!

Han has long announced to the world that it will not seek hegemony and want nuclear peace, which has won the respect of the world. However, Han needs to have its own counterattack ability. It can't let others walk around with nuclear weapons, but it has to be willing to bear it?

The atomic bomb will be developed even in 10000 years! The heroic words of that year inspired a generation. In less than 10000 years, not even 10 years, the nuclear bombs and ballistic missiles of the Han country came out. At the same time, a new force was established to operate ballistic missiles, which is the Second Artillery Corps.

The second artillery, which specializes in special artillery, plays ballistic missiles!

In front, there are several open trucks. They are the most common Dongfeng five ton military vehicles with all wheel drive. These vehicles are generally equipped with field troops.

Now, the body of this kind of car has been transformed into special vehicles. Needless to say, it must be similar to shooting command post, power generation car, positioning car and so on.

Seven or eight of these cars passed, and then you can see a Bellier tractor imported from the chicken country rumbling forward.

When Qin Guan saw the car, he shook his head. At the same time, he was filled with a sense of urgency. The heavy truck project he did as he wanted was urgently needed by the country!

At present, only these backward liberation and Dongfeng five ton trucks and a small number of heavy tractors are imported from abroad. In order to tow missiles, ballistic missile forces can only use expensive imported vehicles. In addition to being expensive, parts and components need to be imported from abroad. In case of war, they will be controlled by others.

Once our truck project is put into operation, we can produce heavy trucks suitable for our needs. At that time, we can replace the Second Artillery Corps first. Don't use such old vehicles.

Qin Guan shook his head and looked at the car rumbling forward. The trailer behind him could also be seen clearly.

In later generations, missile launchers used launchers, which were well sealed to prevent missiles from being damaged in transportation. However, now, they can't solve too many problems. They can only be used. Therefore, they directly towed a trailer made of iron frame in the back. On the surface of the trailer, there is a missile naked.

Under the iron frame, there is a hydraulic device, which can erect the missile and launch it. It can also be said to be the simplest transportation vehicle.

The missile was very long, with a visual eye of more than 20 meters. Qin Guan immediately linked it with what he remembered.

Dongfeng-3 missile!
