Doomsday Bunker Upgrade

Although the original plan was to launch a counterattack after the completion of the Nantianmen plan, because the development and construction cycle of a large-scale aerospace strategic carrier platform is a bit too long, European countries, and even Lucia and Yan Kingdom are ready for counterattack. At the time, the construction progress of the Luanniao large-scale aerospace strategic aircraft platform was still not even half.

After three years of testing and research and development, the theoretical basis research and development of the large-scale aerospace strategic carrier platform, as well as various tests and designs have been completed.

3D printing technology has played an important role in the entire R\u0026D and design process.

This technology makes the manufacture of test prototypes much easier and greatly shortens the construction period, which allows the entire R\u0026D and design process to be shortened to three years, and the construction of this super aircraft can begin immediately after the design and development is completed.

The difficulty of building a behemoth equivalent to at least four aircraft carriers is beyond everyone's imagination.

If nothing else, the factory building itself that can accommodate this behemoth can be regarded as a super project.

Without considering the demolition of the factory building, after the construction of the Luanniao large-scale aerospace strategic aircraft carrier platform is completed, it is also necessary to consider the issue of its departure from the factory building.

Therefore, in addition to having sufficient space to accommodate a behemoth with a width of more than 600 meters and a length of more than 200 meters, the factory building must also have a super gate that is at least 700 meters wide and comparable to a large-span suspension bridge.

If you want to build such a factory in a conventional way, it is difficult for both the designer and the construction unit to die.

However, the solution is always more difficult than the difficulty. After some trial and research, the workshop was erected and successfully completed.

If it is not realistic to repair a gate that is 700 meters wide, try a more realistic design.

Therefore, the design team designed the entire plant to have a fully open top. After the construction of the Luanniao large-scale aerospace strategic aircraft carrier platform, it will not be moved out of the plant from the ground, but will be directly lifted into the air, which can be opened and closed from the top of the plant. The ceiling leaves the factory.

This undoubtedly greatly solves the construction problem of the factory building, and after such a huge factory building is preserved, it can also be used as a hangar and maintenance site for Luanniao.

After all, it is not easy to build such a large factory building, it is too wasteful to dismantle it like this, and Luanniao itself also needs hangars and maintenance sites, so it is a good choice to keep it.

Relying on 3D printing technology, the construction of the plant is also very fast, and at the same time as the construction of the plant, the construction of Luanniao also started simultaneously.

By the time the plant is fully completed, some of Luanniao's basic components have also been manufactured.

Speaking of parts, it is also compared with the huge size of Luan Bird. Some completed parts will not be smaller than that of a large civilian airliner.

As for the most important wing skeleton, even if the skeleton is more than 300 meters long, it will take a lot of time to complete even if it is integrated with 3D printing equipment, and it needs a special site, so the construction progress of Luan Bird is not fast.

According to the expectations of the construction progress, it will take about a year to complete the basic construction of the entire Luanniao, and then it will take about a year for outfitting. Finally, the training and running-in of the crew members will take about one or two years. .

It will take at least three or five years for the entire Luanniao large-scale aerospace strategic carrier platform to be put into actual combat.

However, the European side can't wait.

During the three years that Luanniao was building and European countries were preparing for counterattacks, European countries tried several small-scale counterattacks.

Three years was enough for European countries to complete the refurbishment of all their armies, and they also purchased some small land-running ships and mobile bases from the Yan Kingdom, which greatly improved the combat effectiveness of the army.

Relying on these improved troops, some of their previous defense lines were broken, causing the concave section to try to counterattack, trying to level the defense line and push it back to its original position.

This kind of counterattack has achieved certain results. Although not every counterattack can achieve the expected combat goals, but relying on such a little attack, the European side has recovered a certain amount of lost ground, and the original unevenness is like a dog gnawed. The general line of defense gradually flattened into a straight line.

They managed to pull back most of the previously occupied areas of the entire line, and even hit some salients.

This gave the Europeans a lot of confidence, and they even began to formulate a counter-offensive plan for this purpose. The whole plan was written in such detail that it made people mistakenly think that they were preparing for a world war.

The Yan Kingdom also tried to carry out some attacks. Starting from the defense line in the Middle East that had been completed, they attacked the island of Cyprus, which was closer to the Aleppo area.

Because of the weak offensive of alien creatures in this direction, the joint force composed of the Yan Kingdom and the Middle East army successfully captured the island of Cyprus and established a stable base on it.

Although alien creatures are powerful, after humans can effectively kill and have shields to resist attacks, their threat to humans has actually dropped a lot.

The success of the Yan Kingdom's attack this time is very telling.

After the improvement of human military science and technology, alien creatures can only rely on the number to resist the attack of human beings.

And this has also greatly encouraged the determination of countries to launch a counterattack and completely remove the alien creatures from the Blue Star. At the same time, it also made some European countries do not want to wait any longer.

After all, it has been three years of waiting, and after another three years, the morale of the people will be consumed.

Both Yan Guo and Lucia also understand this situation. After evaluating the power currently possessed by human beings, the two countries still do not agree to start a large-scale counter-offensive immediately, but they also do not object to a small-scale counter-offensive in local areas first.

For example, the recovery of the Aegean region and the Apennine Peninsula.

In the past, one of these two areas was due to rising sea levels, and the other was surrounded by the sea on three sides because of its geographical location. When alien creatures invaded, they quickly fell.

European countries were struggling to defend themselves, so there was no way to face the fall of these two regions.

But now with the strength to fight back, European countries certainly want to regain lost ground.

Especially the Apennine Peninsula, which is located in the middle of the entire Mediterranean Sea. If the lost land can be recovered, the entire Mediterranean Sea can be divided into two parts, and the forces of alien creatures can be divided into two and then annihilated one by one.

This strategy was quickly adopted, and European countries began to gather their forces, and Lucia also sent her own troops to the Asia Minor Peninsula this time, preparing to join forces with the Yan Kingdom's army here, and then launch an attack on the Aegean region.
