(Brothers, you guys are so powerful! Yesterday you actually rushed to the top 30 of the overall list, and the fourth place in the list!) It really scared me, it seems that the posture of asking for votes should really be rolling all over the ground, so I'm rolling a few rolls!)

Hey, just kidding.

As a token of gratitude, there will be an outbreak in two days, please support me as always, thank you Morningstar!

Gentlemen, slaughtering the gods and destroying the Buddha is imminent!)

Eschatological.

After more than half a month of hard work, the xenomorph nests on the west side of the entire Wanghai City have been basically cleared. In addition to this, NAC soldiers have deployed eleven checkpoints along the Huangpu River, blocking all bridges from the West City to the East City to prevent the spread of xenomorphs from the East to the West.

Now the entire West Side, both on the surface and in the sewers, has been cleared of xenomorph nests by mercenaries and NAC troops. Although it is difficult to eradicate xenomorphs such as mutant cockroaches and rats, the more aggressive xenomorphs such as zombies, Roshan, and even Deathclaw are basically invisible in the entire West End. Succumbing to the NAC's force, survivor groups large and small in the western district of Wanghai City have submitted to NAC's rule.

The mercenary groups and marauder groups that were originally unclean have also followed the good and the out-migration. Having witnessed the overwhelming rain of rockets, they really couldn't raise the slightest idea of resisting. The NAC has used its force to assert its dominance over Wanghai City.

Even Liuding Town, which was originally on an equal footing with the Sixth Block, is now a little inadequate in the face of the behemoth of NAC.

It's better to say. When they saw the bombardment of the city center by the Staff of God, they were completely convinced. They didn't know that the NAC was fighting the Supreme, only that they had a plan to wipe out the xenomorph nests in the city center. And so. They mistakenly believed that the tungsten rod bomb was fired by someone from the NAC......

In addition to establishing its dominance, the NAC also sent sappers in nuclear protective suits to the city center to clean up the radioactive sources that had accumulated in the city center.

Hard-to-remove radioactive material is contained in lead barrels, thrown into a pit in the center of the city that has been blasted by tungsten rods, and poured with leaded cement for landfill. The lightly radiated areas are sprayed with radiant cleaning liquid, and it is believed that it will not be long before it. Gamma levels will return to normal levels throughout the city center.

In addition, there are exploration teams sent to the ruins of atomic energy companies, scientific research centers, and industrial bases to search for pre-war technology, and all collected technical documents will be sent to Camp 27 for aggregation and sorting. The city center, "protected" by radiation, is like a treasure that has not yet been destroyed. Many of the technical materials hidden in the underground bunkers are relatively well preserved and of high value, and the more than 1,000 scientists in Camp 27 are suddenly busy.

The Huangpu River, which crosses Wanghai City, resembles a Berlin Wall, and on the left is the orderly NAC occupation zone. On the right is a chaotic "reservation".

With the end of the xenotide tide. Survivor groups in the East Side have returned to their homes built on the ruins from large survivor bases such as Liuding Town to start a new life. But after witnessing the gap between the two sides of the Huangpu River, there is no need for too much publicity, and the survivors who yearn for the safety and stability of the western urban area have migrated to the west bank of the Huangpu River with their families.

The NAC checkpoint occupying the Huangpu River Bridge did not stop them from migrating, but all survivors who had migrated from the eastern city to settle in the NAC-ruled area were required to hand in dangerous goods such as nuclear grenades and mini-bombs. The policy of denuclearization has been pushed outward from the Sixth Block and spread throughout the NAC district.

At this moment, Wanghai City Airport.

More than a dozen engineering trucks are shuttling and plowing on the runway of the airport. Repairing the shattered airstrip that had been bombed during the war. The repair was tendered by the NAC and the Metal Shell Chamber, the largest builder in the 6th block. The 2nd Corps is responsible for ensuring the safety of the construction site.

This pre-war civilian airfield has been requisitioned by the NAC as the NAC's first military airfield, and is under the management of the nearby Camp 27. At this moment, in the apron of the airport, a flat shuttle-shaped ******-shaped fighter is lying quietly, resembling a petrel, named Aurora-20.

At this moment, Jiang Chen was standing in front of the tarmac, under the leadership of Fang Weixian, to visit the new weapon developed by Vault 27.

"Aurora-20, a fixed-wing fighter, can take off in two modes: vertical take-off and landing and runway. The belly can carry 2 short-range anti-aircraft missiles and 4 medium- and long-range anti-aircraft or surface-to-surface missiles, and a 10mm cannon is mounted in the nose. According to your requirements, the firepower is absolutely reliable!" Fang Wei patted the nose of the plane first and grinned at Jiang Chen.

Including Tiger Hunter II and Yunzhi-51, the cutting-edge military products of the entire NAC are basically from the technical team led by Fang Weixian.

Nodding approvingly, Jiang Chen looked at this powerful fighter.

"What about stealth and speed?"

Concealment and speed are the life of a fighter, and the thickness of the armor is not of great significance at high altitude, no matter how advanced the fighter is, it is difficult to withstand the direct attack of two missiles.

"The aircraft shell is coated with radar signal attenuation coating, which on most radars shows an area equivalent to a sparrow. The radar signal detection system at the bottom of the aircraft can track the coordinates of the ground radar base station in reverse. As for speed, the top cruise speed can reach Mach 4.5. The corners of Fang Weixian's mouth hooked up a smug smile.

Jiang Chen was also very satisfied with this figure.

The maximum speed of Mach 4.5 has exceeded the record of Mach 3.2 set by the MiG-25 high-altitude high-speed interceptor on the other side, and is close to the speed limit that a fighter in the atmosphere can reach.

Of course, in the case of close combat, it is naturally impossible to use the maximum speed for combat. Otherwise, let alone Mach 4.5, even if it is a speed of Mach 2, the acceleration of the plane will make the pilot faint when it turns casually.

In addition, according to Fang Weijie's introduction, this "Aurora-20" fighter can have a combat radius of up to 3,100 kilometers without the support of tankers, which has far exceeded the record of 2,177 kilometers set by the US F22. On the one hand, the new titanium alloy material used in the aircraft makes the aircraft much lighter than the fighter jets of the 21st century. On the other hand, it is because the engines and synthetic fuels used in the aircraft are better than they are in the 21st century.

"From the engine to the fire control system, it's the military technology of PAC. From the landing gear of an airplane to an air-to-air missile, it is all made by 3D printing technology. ”

"How feasible is industrial production?" Jiang Chen asked.

3D printing is more expensive. A lot of materials and energy are wasted. The cost of 3D printing to produce a fighter jet is about three times that of an industrial production line. Although NAC has a lot of money, if any cutting-edge weapons rely on 3D printing technology, Jiang Chen, who burns this money, is still a little distressed.

"It's hard, it's hard to do it with the heat-resistant materials of the engine, at the industrial level of the sixth block. Fang Wei shook his head first.

Jiang Chen thought for a moment and said.

"The means of production of some of the parts with simple processes were handed over to the military factory in the sixth block. Whenever possible, these parts are outsourced to them. In this way, the cost should be much lower than 3D printing, and the production cycle can be shortened. Do you think it's feasible?"

Fang Wei pinched his chin and meditated hard.

Strictly speaking, there is no part that is simple to ......

Jiang Chen shook his head and said with a smile.

"When I say simple process, I don't mean how easy it is to produce according to the production process we know. It's about technical feasibility. Don't underestimate the creativity of the people of the wasteland. As long as we offer the right price and are technically achievable, they may be able to develop a more cost-effective production process than we do. ”

Regarding Jiang Chen's statement, Fang Weixian was obviously not very convinced. After all, he came from the refuge and belonged to the elite before the war. He really didn't believe that the survivors, dressed like "beggars", were capable of solving the problem of the production of fighter parts.

However, due to the disparity in status, he did not show his disdain for the survivors of the wasteland.

Seeing that Fang Wei didn't speak first, Jiang Chen probably guessed what he was thinking. But he just smiled. Didn't say much on this issue.

Fang Weixian is very arrogant, but this arrogance is not arrogance for no reason. Rather, it stems from his technical rigor

"Science and technology are two different things, the former determines the development space of the latter, and the latter determines the practical value of the former. Being able to survive the brutal apocalypse to this day has proven the creativity of the survivors. ”

"But you can't expect a group of refugees to do the job of a technician...... Well, if you insist. I want to think about it...... Screws, wings, canopies, ejection seats, operating interface shells and the like, about 60% of the basic parts are not very technically difficult. Sighing as if giving up, Fang Weijie said.

"Good. Jiang Chen nodded and patted the technician's shoulder with satisfaction, "You can list these parts in detail and give them to Xu Lu." The rest of the parts are still produced by 3D printers. ”

"Understood. Fang Weijie bowed slightly.

They were only responsible for R&D and building the first prototype, providing drawings and production details. As for the specific matters of production, the military factory of the fish bone base will be in charge, and there is no need for scientists like them to worry too much.

"Regarding the next scientific research project," Jiang Chen paused, looked at Fang Weijie and said seriously, "I hope you will develop an airship that can stay in the air for a long time, has armor protection capabilities, and has basic firepower." ”

"Airship?Armor Protection Capability?" Fang Weijie was stunned and frowned slightly, "Is it still made of steel?"

"Is it technically difficult to achieve?" Seeing Fang Weijie's embarrassed look, Jiang Chen asked.

"No, it's not technically that hard to implement, it's just ...... I've never heard of an airship. Fang Weijie said helplessly.

He had never heard of what he said, so naturally he had to be before the war. Not to mention that before the war, airships, which were air units with poor mobility and large targets, were eliminated as early as the beginning of World War II. Although with the technology of the 22nd century, it is not very difficult to build a steel airship, but Fang Weijie is deeply skeptical about how cost-effective such a weapon can be.

So he euphemistically said that he had never heard of this kind of weapon, and hoped that Jiang Chen would change his mind.

"It doesn't matter, there was no pre-war, just build one from beginning to end with pre-war technology. However, Jiang Chen did not change his mind.

"But to build such a fortress in the sky, the amount of steel, titanium alloy, copper, and aluminum needed will be astronomical. From the point of view of cost performance, does this thing really make sense?" Fang Weijie questioned.

"Of course it makes sense. Jiang Chen said with a smile.

As he spoke, he looked at the sky outside the airport.

It was clear there, but further afield, it was still cloudy.

Looking at Jiang Chen's line of sight, he asked, who didn't understand Jiang Chen's meaning.

"What is it?"

"Spread our will, our order, our philosophy, farther and farther. (To be continued.) )
