The expressway, in normal times, is a standard highway used for cargo transportation, but in wartime, it can become a runway when it is transformed. This is of very important and practical significance.

Once a war starts, the airport must be the enemy’s first strategic strike target. In the first wave of attacks, the airport may have all been blown up. Even if the aircraft still exists, without an airport, the aircraft cannot be launched. In this way, air supremacy will fall into the enemy's hands.

Although there are various means, such as temporary runways, etc., it is always good to have one more option. Ordinary roads will not work. The standard is not enough, and it is impossible to let fighter planes take off and land. That said, ordinary roads are not enough.

Only highways have this condition. Therefore, when this highway runs from north to south, some special sections were set up in it when it was built. Once these sections were in war, they could be used as runways for airplanes at any time. .

This time, Major Yang came here naturally to organize this exercise. Various new exercise plans were born from Major Yang.

"We plan to close the road at three o'clock tomorrow morning. It will take two hours to complete the runway modification by five o'clock. At seven o'clock, the first batch of fighter planes will land and refuel. , Hang bombs and so on, let go again." Major Yang said to Qin Guan.

Although Qin Guan put forward this idea, there are still a lot of technical problems to realize it. A non-professional person like Qin Guan does not actually understand these problems.

For example, not all expressways can meet the conditions for take-off and landing. For example, ordinary roads, even the highest grade, have insufficient thickness underneath to meet the requirements for take-off and landing. Therefore, these highways are being constructed. At the time, reinforcement must be carried out, and the paved roadbed and pavement should be thicker.

Secondly, there should be no routes for civil aviation aircraft nearby, so that it can facilitate take-off and landing operations and avoid collisions with civil aviation aircraft. At the same time, try to choose a place with a service area. You must know that after the aircraft has landed, refuel, hang bombs, etc. All the operations of the aircraft require a variety of vehicles. Take off and land must be commanded, etc. If these are not supported by a service area, will they be placed directly on both sides of the road?

Although it is now a three-lane highway, it is said that the width is not small, but it is still far from enough for aircraft to take off and land. Therefore, in actual operation, the two-way lanes are merged together.

In this way, when designing, there must be no sunken green belts in the middle of the lanes in these areas. They must be even and flush. Then, the metal isolation belts and road signs in the middle must be quickly removed, and traffic control is carried out on both sides. Vehicles at the exits on both sides were forced to leave the road ahead of time.

This series of measures will take at least two hours to complete, which is already a very high standard.

"Actually, I think one should be added." Qin Guan said: "If the highway is close to our air force base, a road can be built to reach it directly."

Although it is said that the highway can take off and land fighters, in fact, it is to provide a landing site for those fighters that take off. After taking off, their own airport is destroyed. Then after the battle, where can they land? This is the advantage of the road runway.

What if the runway is blown up if the plane has not taken off yet? When vertical takeoff and landing fighters became popular decades ago, they wanted to be able to take off fighters even when the runway was bombed. Unfortunately, the engine’s thrust was insufficient and it was destined to be a tasteless commodity. This will continue to develop into the later F35. , It is considered to have such conditions.

Qin Guan had this fantastic idea, since the highway can take off and land fighters, can the fighters be directly towed to the runway to take off when needed? In the case of being bombed at the airport and the plane has not yet taken off?

"No, if that's the case, this highway will also be blown up." Major Yang said.

"Then we can quickly fill it up with engineers." Qin Guan said.

Major Yang shook his head: "If the engineers can fill the crater on the highway, why not directly fill the crater on the runway so that the runway has the ability to take off fighters?"

Qin Guan smiled. That's right, he is really a layman. At this time, where is the need to drag the fighter directly over, it is more appropriate to repair the crater.

Of course, for the runway, the most effective strike weapon is not one or two bombs at all, but cluster bombs! After the explosion, thousands of small bullets fell down, and there were craters everywhere. Those bullets that did not explode were a more effective strike force and could turn the airport into a hell.

This kind of weapon is quite terrifying, so it is also listed as a banned item by international organizations. However, if superpowers use them everywhere, they will not care about loose international organizations that have no execution capabilities.

"There are so many vehicles here." Qin Guan awkwardly changed the subject. As a person who promoted domestic military modernization, he made such a low-level mistake. Qin Guan chose to shift his attention and focus on other places. .

"The vehicles here are mainly used for the maintenance of the fighter planes and take off again." Major Yang introduced: "Fortunately, our fighter planes are now highly reliable and easy to maintain. If it were the previous fighter planes, again. The efficiency of the dispatch must not be high."

Fighter engines, various equipment, etc., have a long lifespan and routine inspections are quite simple. This is the advantage of Western weapon standards.

"What are those?" Qin Guan looked at some pallets. The tops of the pallets were covered with tarpaulin. They were clearly infantry fighting vehicles or tank-like things. These things appeared here. They were nondescript. The name was infantry. The equipment of the army, the army, how come to the air force?

"This time, we will not only take off and land fighter jets, but also plan to take off and land large transport planes. We will also carry out an emergency assembly of paratroopers and board the aircraft to participate in the battle. The equipment is for paratroopers."

Hearing this, Qin Guan was shocked, paratrooper? Transport aircraft? After the highway is improved, it will be good to be able to take off and land fighter jets. Can it also take off large transport aircraft?

In Qin Guan's mind, a group of data emerged. The standard lane width of the expressway is 3.75 meters, the emergency parking zone on the right is 2.5 meters, and the central isolation zone is calculated at 1 meter, with 6 lanes in both directions, plus emergency parking. The belt is 28.5 meters, if you include other ancillary facilities such as guardrails, the maximum is 32.5 meters.

At this time, the fighter is fine. If the transport plane is used, the wheels should be aligned. Of course, the wings must be drooped outside.
