Although the original plan was to launch a counterattack after the completion of the Nantianmen Plan, due to the long development and construction cycle of large-scale aerospace strategic carrier aircraft platforms, countries in Europe, and even Lucia and Yanguo, were ready for counterattack. At that time, the construction progress of the Luanniao large-scale aerospace strategic aircraft platform was still not even half of it.
After three years of testing and research and development, the theoretical basic research and development of the large-scale aerospace strategic carrier aircraft platform, as well as various tests and designs, have been completed.
?? 3D printing technology plays an important role in the entire R&D and design process.
This technology makes it much easier to manufacture test prototypes and greatly shortens the construction period. This can shorten the entire research and development design process to three years, and start the construction of this super aircraft immediately after the design and development is completed.
"It is difficult to build a behemoth equivalent to at least four aircraft carriers beyond everyone's imagination.
Not to mention anything else, just the factory 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 platform is completed, it is still necessary to consider the issue of its leaving the factory building.
Therefore, in addition to having enough 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 long-span suspension bridge.
If you want to build such a factory using conventional methods, it will be difficult for both the designer and the construction unit.
However, there are always more solutions than difficulties. After some attempts and research, the factory was built and successfully completed.
If it is unrealistic to build a 700-meter-wide gate, then try a more realistic design.
Therefore, the design team designed the entire factory with a fully open top. After the construction of the Luanniao large-scale aerospace strategic aircraft platform was completed, it did not move out of the factory from the ground, but directly lifted into the air. It can be opened and closed from the top of the factory. The roof leaves the factory building.
This undoubtedly greatly solves the problem of factory construction. After such a huge factory 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. It would be too wasteful to demolish it. Luanniao itself also needs a hangar and maintenance space, so retaining it is a good choice.
Relying on 3D printing technology, the construction of the factory building was also very fast, and at the same time that the construction of the factory building started, the construction of Luanniao also started simultaneously.
By the time the factory is fully completed, some basic parts of Luanniao have also been manufactured.
Speaking of parts, they are compared with the huge size of the Luanniao. Some completed parts are no smaller than a large civilian airliner.
As for the most important wing frame, the more than 300-meter-long frame will take a lot of time to complete even if it is integrated with 3D printing equipment, and requires a special site, so the construction progress of Luanniao is not fast.
According to the expected construction progress, it will take about one year to basically complete the construction of the entire Luan Bird, and then it will take about another year to outfit, and the final training and running-in of the crew members will also take about one or two years. .
It will take at least three to five years before the entire Luanniao large-scale aerospace strategic aircraft platform can truly be put into actual combat.
However, Europe can¡¯t wait any longer.
During the three years when Luanniao was under construction and European countries were preparing for counterattacks, European countries attempted several small-scale counterattacks.
Three years were enough for European countries to complete the re-equipment of all their armies, and they also purchased some small land craft and mobile bases from the Yan Kingdom, which greatly improved the combat effectiveness of their armies.
Relying on these troops with increased combat power, they tried to counterattack in some concave areas where the previous defense lines were breached, trying to level the defense lines and push them back to their original positions.
Such counterattacks have achieved certain results. Although not every counterattack can achieve the expected combat goals, relying on such attacks bit by bit, Europe has regained a certain amount of lost ground, and the originally uneven ground was like a dog gnawing. The general defense line gradually flattened into a straight line.
They successfully pulled back most of the previously occupied areas of the entire defense line, and even created some salient areas.
This gave the Europeans a lot of confidence, and they even began to formulate a counterattack plan. The entire plan was written in such detail that it made people mistakenly think that they were preparing for a world war.
Yan Guo also tried some attacks, starting from the defense line in the Middle East that has been completed, and attacking the areas far away from Aleppo.?An attack was carried out on the closer island of Cyprus.
Because the alien biological offensive in this direction is not strong, 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 them and have shields to resist attacks, their threat to humans has actually dropped a lot.
The smoothness of Yanguo's attack this time speaks volumes.
After the improvement of human military technology, alien creatures can only rely on numbers to resist human attacks.
This has also greatly encouraged various countries to launch a counterattack and completely eliminate alien life from Blue Star. At the same time, some European countries do not want to wait any longer.
After all, we have been waiting for three years. If we wait another three years, the people's morale will be exhausted.
Yan Guo and Lucia also understand this situation. After assessing the current power of mankind, the two countries still do not agree to start a large-scale counterattack immediately, but they are not opposed to carrying out small-scale counterattacks in local areas first.
??For example, recovering the Aegean Sea region and the Apennine Peninsula.
In the past, one of these two areas was due to rising sea levels, and the other was due to its geographical location surrounded by sea on three sides. They quickly fell when alien creatures invaded.
European countries have struggled to defend themselves before, so there is nothing they can do to face the fall of these two regions.
But now that they have the power to fight back, European countries certainly want to regain their lost ground.
Especially the Apennine Peninsula, located in the middle of the entire Mediterranean. If the lost territory can be recovered, the entire Mediterranean can be divided into two parts, and the alien forces can be divided into two and then annihilated area by area.
This strategy was quickly adopted, and European countries began to gather troops. Lucia also sent its troops to the Asia Minor Peninsula this time, preparing to join the Yan Kingdom's army here, and then launch an attack on the Aegean Sea area.
