Under the instructions of Chen Weidong and Lin Zeju, both domestic and African bases have been making various preparations for the Utopia Plan for several years.

They fought hard in the shopping mall and earned large sums of money, effectively supporting the smooth progress of the Utopia project.

Including at the press conference, the spokesperson claimed that this was only a preliminary test of lunar exploration and that the aerospace aircraft was far from perfect.

But in fact, let’s not talk about the three-year data flight test of the ten-meter shrinkage data collection machine organized by Zhao Gong and others in the southwest region.

Even this 98-meter full-scale verification aircraft has been tested for takeoff, landing, and low-altitude performance more than once or twice.

However, because the verification aircraft has never reached medium and high altitudes, and among the mountains in the southwest, it is difficult for foreign long-range radars to detect targets at such long distances and under complex terrain conditions.

It was not discovered by the national monitoring station.

Now, the vast mountains in the southwest have become Infinite Company's secret base specifically for testing heavy equipment.

A few years ago, the location of the base was just a river valley.

The water flow brought abundant soil and sand, which after reverberating in the valley, settled down and gradually filled the valley into a gentle valley.

Engineers repaired the entrance of the valley and built a dike to prevent the river from flowing back during the rainy season.

After that, they leveled the land in the valley and built factories and dormitories in patches.

The sealed environment at the bottom of the valley and the natural terrain shaped like a basin are an excellent location for building a confidential factory.

In order to transport supplies, the military also specially allocated a large amount of manpower and material resources to build an asphalt road leading outside the mountain.

Soldiers are stationed along the road, responsible for checking the road conditions along the way, so as to carry out timely road repair and maintenance and ensure smooth access of materials.

This winding path, about ten meters wide, is the secret factory and the only way to maintain communication with the outside of the mountain.

At the mouth of the valley, there is a battalion of soldiers stationed here all year round.

All people entering and leaving must wear identification tags, and everyone has a complete file. Even strangers with letters of introduction from the province or military divisions cannot enter the valley.

Anyone who dares to break in will definitely be shot to death on the spot.

From here on, there are warning lines every five hundred meters.

There are three such cordons.

In addition to light firepower, there are also heavy equipment such as wheeled armored vehicles and transport helicopters.

Warning posts were installed on the surrounding hills. Telephone lines were crisscrossed. Surveillance cameras were all over the hills, covering 360 degrees, with no blind spots in all directions.

Thirty kilometers away from the valley, there are two ground radar stations monitoring the sky.

More than a dozen sets of anti-aircraft missile positions are scattered around the valley.

High-speed aircraft positions, anti-aircraft gun positions, and individual air defense missiles form a high-low air defense system.

Although there is no protection from Air Force fighter planes, in the southern theater several hundred kilometers away, two squadrons newly equipped with J-10 fighters are ready at any time.

There are two planes on duty every day, hovering over the southwest mountainous area, euphemistically called familiarizing the equipment.

In fact, as long as they give an order, they can rush to the sky above the base and provide air cover within ten minutes.

With such strict protection, unless the enemy uses long-range nuclear missile attacks, no one will be able to shake the base in the slightest.

Moreover, over the past few years, engineers have been blasting at the heart of the mountain, preparing to hollow out the interior of the mountain.

Once the entire project is completed and the several-meter-thick lead-iron alloy door is closed, even if a nuclear bomb attack is used, the production base may not be wiped off the map.

Such tight protection has never been seen before.

What exactly are they protecting?

The answer will soon be revealed.

Under the protection of a large number of leading vehicles and rear guard vehicles, 50-wheel heavy-duty military trucks slowly moved into the base in the night.

The machines unloaded from the truck range in size from seven to eight meters square to tens of meters in size.

And these are just some parts of a complete machine!

These parts were carefully transported to the factory by technicians and installed under the guidance of another group of people wearing dark blue uniforms.

The time for transporting parts was all arranged at night, and the time for the American satellite to take off was accurately calculated, and the parts were delivered quietly.

This process lasted for two or three months.

Under the guidance of Infinite Company's engineering and technical experts, huge machine tools were installed one by one, and with post-debugging and precision calibration, this batch of large machine tool equipment was initially installed.

At this point, this is the core of China's military industry.

Tank turret?

Cast in one go!

Large aircraft engine?

no problem!

The special production line can complete the processing in one go without changing the machine tool.

Without changing to a better alloy formula, the strength of the engine has increased by anywhere from ten to more than ten percent.

Fuel consumption has been greatly improved, and the airborne time has been greatly increased.

The service life has jumped from a few hundred hours to nearly a thousand hours.

It greatly extends the service life of military equipment in peacetime and reduces armament maintenance costs.

Submarine propellers, new high-precision ultra-large machine tool equipment, and processed submarine propulsion blades can reduce the power propulsion noise to less than 80 decibels when the submarine is traveling on the seabed.

It was completely covered by ocean surges and the noise of underwater creatures, making it impossible for the enemy's underwater sonar to detect it.

Rocket engines, large warship keels, fighter aircraft shell casting...

With the continuous operation of the base, from the initial single-piece trial production, to the mid-term small batch processing, to the later stage, the three armies lined up to send the main components of large-scale military products here for manufacturing one after another.

This base has officially played the role of the core of China's military industry.

The J-10 is still the same J-10, but its improved engine gives it more powerful power.

The take-off weight increased from thirteen tons to seventeen tons, which increased the load capacity by more than four tons.

The powerful power support greatly improves the fighter's climbing ability and turning radius, making air combat flexibility more prominent.

If we say that the performance of the J-10 was previously promoted to be equivalent to the F16, there is a psychological comfort factor in it, but the modified J-10 is no less inferior to the F16 in terms of its air combat performance.

In addition, a new model of nuclear-powered attack submarine, its shell casting and propellers were all trial-produced by Infinite Company's machinery department at this foundry base.

After the final assembly was launched, the test results were extremely satisfactory to the Navy.

Since then, during combat readiness patrols, this type of submarine has "accidentally entered" our waters several times from the front of the Japanese fleet, suddenly surfaced without warning, and appeared in front of the opponent's fleet.

Scared them into a cold sweat and kept them away from this sea area.

In the official submission document of the other party, this new model of submarine is called a "ghost submarine".

Wandering in the deep sea, coming and going without a trace, elusive and impossible to trace.

The military's strategic duty nuclear submarine built a test boat and after a year of testing, all the remaining shell and blade manufacturing tasks were handed over to Infinite Company's large equipment casting base.

The military's large-scale weapon systems have achieved a huge leap in overall performance through the ultra-high-precision equipment manufactured by Infinite Company.

By 2010, the mountainside project was completed.

The engineers used TNT to blast out a huge space that extended underground and covered dozens of square kilometers.

The thickest part is two to three kilometers long, while the weakest part is only one or two kilometers long, which is enough to withstand a frontal attack by a nuclear bomb.

Internally, there are engine casting workshops, large deformation equipment manufacturing workshops, and special equipment manufacturing workshops, etc. There are more than ten large workshops in total.

Each workshop is divided according to levels.

In total, it can accommodate tens of thousands of people to work, live and rest inside.

The new foundry base operates in three eight-hour shifts. After each shift at the entrance of the cave, the eight-meter-thick lead-iron alloy gate will be driven by a high-power motor to slowly close to prevent emergencies.

There is an air filtration system inside the mountain, and it is connected to underground water. In addition, a large amount of food and equipment are stored.

In possible critical moments, the cave can protect 20,000 people from the outside environment within a year.

After the factory was relocated to the center of the mountain, the temporary factory building outside became vacant.

However, it was only vacant for less than half a year before new staff arrived.

This is the aerospace aircraft test team led by Zhao Gong.

They retained a factory building near the mountain wall, and the other buildings were knocked down and filled in.

After that, high-grade cement was transported from outside the mountain and a ten-kilometer-long ultra-long runway was built.

The collection machine used to test data is only about one-tenth of its full size and is about ten meters long.

However, because the aerospace aircraft must ensure supersonic flight, it cannot adopt the shape design of a conventional aircraft. An excessively long wingspan will create strong resistance during flight.

Therefore, the aerospace plane designed by Infinite Company uses what is called a "rising body" in supersonic aerodynamics.

That is, a blunt triangle.

An aircraft with this shape design will form an upward lifting force when flying at supersonic speed, reducing power consumption and saving energy.
