Although the original plan was to launch a counterattack after the completion of the Nantianmen project, because of the long development and construction period of the large-scale aerospace strategic carrier platform, European countries, and even Lucia and Yan countries have made counterattack preparations. At the time, Luanniao's large-scale aerospace strategic carrier platform construction progress was still not even half of the progress.

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

In the entire R&D and design process, 3D printing technology has played an important role.

This technology has made the manufacture of test prototypes much easier and greatly shortened the construction period. This will shorten the entire R&D and design process to three years, and start the construction of this super aircraft immediately after the design and development is completed.

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

Not to mention anything else, just the factory building that can accommodate this behemoth can be regarded as a super project.

Without considering the dismantling of the plant, after the construction of the Luanniao large-scale aerospace strategic carrier platform is completed, it is also necessary to consider the issue of leaving the plant.

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

To build such a factory building in a conventional way is something that can be difficult for both the designer and the construction unit to die.

However, the solution is always more difficult than the difficulty. After some trials and research, the factory building was built on the ground and successfully completed.

If it is unrealistic to build a gate that is 700 meters wide, try a more realistic design.

Therefore, the design team designed the entire factory building into a fully open top style. After the construction of the Luanniao large-scale aerospace strategic carrier platform is completed, it does not move out of the factory from the ground, but directly lifts into the air, which can be opened and closed from the top of the factory. The ceiling leaves the plant.

This undoubtedly greatly solves the construction problem of the plant, and after such a huge plant is retained, it can also be used as a hangar and maintenance site for Luan Bird.

After all, in the final analysis, the construction of such a large plant is not easy, and it is too wasteful to dismantle it like this. Luan Bird itself also needs a hangar and maintenance space, and it is a good choice to keep it.

Relying on the 3D printing technology, the construction of the factory building is also very fast, and at the same time that the construction of the factory building starts, the construction of Luanniao also starts simultaneously.

When the plant is fully completed, some basic parts of Luan Bird have also been manufactured.

Said it is parts, it is also compared with the huge size of Luan Bird, some finished parts are not smaller than a large civilian airliner.

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

According to the expectations of the construction progress, it will take about one year to complete the entire Luan Bird, and then it will take about one year to outfit, and the final training of the crew members will also take about one or two years. .

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

However, the European side can't wait.

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

Three years are enough time for European countries to complete the refitting of all armies, and they have also purchased some small land cruisers and mobile bases from Yan Country, which greatly improves the combat effectiveness of the army.

Relying on the increased combat power of the army, some of their previous defense lines were breached, and the recessed areas attempted to counterattack, trying to flatten the defense lines and push them back to their original positions.

This kind of counterattack has achieved certain results. Although not every counterattack can achieve the expected combat goals, but with such a bit of attack, the European side has regained a certain amount of lost ground and turned the original jaggedness like a dog. The general line of defense gradually flattened into a straight line.

They successfully pulled back most of the previously occupied areas of the entire defense line, and even made some protrusions.

This gave the Europeans a lot of confidence, and they even began to formulate a counter-offensive plan for this. The whole plan was written so meticulously that people thought they were preparing to fight a world war.

The Yan country also tried to carry out some offensives, starting from the already constructed defense line in the Middle East, and attacking the island of Cyprus, which is closer to the Aleppo area.

Because of the weak offensive of aliens in this direction, the joint force formed by the Yan Nation 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 decreased a lot.

The success of the Yan State offensive this time speaks volumes.

After the advancement of human military technology, alien creatures can only rely on numbers to counter human attacks.

This also greatly encouraged countries to launch a counterattack and completely remove the aliens from the blue star. At the same time, it also made some European countries no longer want to wait any longer. UU Reading www.uukanshu.com

After all, we have waited for three years. If we wait for another three years, the morale of the people will be consumed.

Both Yan Country and Lucia understand this situation. After the two countries have assessed the power currently possessed by mankind, although they still do not agree to start a large-scale counterattack immediately, they do not object to a small-scale counterattack in a local area first.

For example, recover the Aegean region and the Apennines.

In the past, these two regions were due to rising sea levels and the other being surrounded by sea on three sides, and they soon fell when alien creatures invaded.

European countries used to be very difficult just to defend, so naturally there is no way to face the fall of these two regions.

But now that they have the power to counterattack, European countries certainly want to regain their lost ground.

In particular, the Apennine Peninsula is located in the middle of the entire Mediterranean. If the lost ground can be recovered, the entire Mediterranean 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. European countries began to build up their forces, and Lucia this time sent his own army to Asia Minor, preparing to converge with Yan's army here, and then launch an attack on the Aegean area.
