Because, the indigenous people are limited by backward means of transportation, no horses, no boats, and no cars, and in the wilderness around the indigenous tribes, the jungle is full of fierce beasts, mammoths, saber-toothed tigers, wolves, crocodiles, and very dangerous, so the range of activities of the indigenous people is very small, with a radius of dozens of kilometers and a radius of 100 kilometers.

Therefore, the location of underground caves does not exceed a radius of 100 kilometers.

Chen Rui escaped in the underground soil for more than two hours.

Suddenly, Chen Rui felt that he had broken through the soil layer and came to an underground space.

Chen Rui took out a flashlight from the pregnant Haizhu space, turned on the flashlight, and the light of the flashlight shone through.

Illuminate the underground space.

Taylor. C. Martin put a lot of thought into keeping the Book of Doom and the fighter jet alive in the flow of time.

The place where the underground space was built was chosen a very dry soil layer, which was isolated from groundwater, as well as the erosion of the humid environment and the oxidation of the metal caused by the air.

The underground space is reinforced with huge chunks of cut and leveled rock.

Prevent the underground space from collapsing due to the pressure of movement, extrusion, folding, and deformation of the geological structure layer.

The fighter was parked right in the middle of the underground space.

Due to the fact that the fighter is kept in the underground space isolated from water, air and humid environment, as well as the metal shell of the fighter, the metal of the parts and components, and the engine are made of aluminum alloy and alloy materials, which have extremely strong strength, toughness and corrosion resistance, fatigue resistance, plus the separator material applied on the fuselage, the fighter is relatively well preserved.

Some of the first signs seen in the fuselage.

A red and blue bar, the symbol of a blue circle and a white star, which is the emblem of the United States Air Force.

On the vertical tail of the aircraft there is a squadron insignia.

In the nose of the aircraft there is a merit mark. Sprayed with 2 stars. Indicates that 2 enemy aircraft were shot down.

On the fuselage there is also a sign of combat experience. Sprayed with 14 missiles, it represents 14 combat missions

Various insignia on fighters embody the dignity and honor of aviation.

The appearance of this fighter is very different from the common American models F15, F16, F22, F35, and even from any fighter model in the world.

The fuselage curved surface is flattened, smooth and smooth, the fuselage, wings and tail in the traditional sense are blurred, the tandem three-wing surface aerodynamic layout, and the front-mounted full-motion close-coupled canard wing is fully integrated with the fuselage strip. The forward-swept wing is completely integrated with the fuselage, the wing root extends backward to the tail to form a horizontal stabilizer, the double vertical tail is cambered at a large angle, and the S-shaped air intake is ultra-flat and dynamic.

If Chen Rui guessed correctly, this is the last fifth-generation fighter of the United States, which is one generation more than the F-22 and F35. Compared with the F-22 and F-35, there is also a world of difference in combat effectiveness.

According to the performance of the fighter. There are two standards for dividing the algebra of fighters: one is the standard of the West led by the United States, and the other is the standard of Russia, the difference is that the Russian division is divided from the beginning of the appearance of jet aircraft, while the American division is divided from the jet fighters that appeared after World War II, so the fifth generation usually refers to the Russian division standard, which is equivalent to the fourth generation of the United States.

We usually use American standards.

Typical first generation, American F86, F100, F106, Soviet, MiG-15.

Typical second generation, American, F-4, F-5, Soviet MiG-21, Chinese J-7, J-8.

Typical third generation, American F15, F16, F18, F14, Russian Su-27 series, MiG-29, Chinese J-10, J-11.

Fourth generation, F-22, F35, YF-23, X-32, Chinese J-20, J-31, Russian T-50.

In addition, there are three and a half generations, that is, the improved type of the third generation, which is actually divided into the third generation.

At present, the most advanced fighters are the fourth-generation fighters, F-22, F35, which have entered service and are far ahead, the Chinese J-20 and J-31, and the Russian PAKFA are still flying test, and there is still a very small distance to go before entering service to form combat effectiveness.

Fifth-generation fighters are still in the imagination of various countries.

At present and for a long time to come, third-generation aircraft will continue to occupy a considerable proportion of the world's air armament systems, and will even continue to play the main role.

The combat effectiveness of fighters is very different from one generation to the second generation, the second generation to the third generation, and the third generation to the fourth generation.

The US military once exercise, the fourth-generation famous fighter F-22 versus the third-generation famous fighter F16 had a victory rate of 108:0, although the Americans announced these data mainly for propaganda, but one thing is certain, the cross-generation fighter combat effectiveness is very different.

The fifth-generation fighter in front of the United States, compared with the fourth-generation strong aircraft F35 and F22, has crossed a generation, and uses more cross-generation and beyond the technology of this era, supersonic cruise, ultra-conventional maneuvering, broadband or even full-range stealth, air-space integration, airborne new concept weapons, and more outstanding air-space information fusion capabilities.

If any country has a fifth-generation aircraft, other countries' third-generation aircraft, or even fourth-generation aircraft can be swept into the garbage can, the scramjet engine, pulse detonation engine, turbine/ramjet combination engine, new aerospace material technology, airborne laser (ABL), advanced tactical laser weapons (ATL), and joint high-energy solid-state laser weapons (JHPSSL) on the fifth-generation aircraft have completely destroyed the third-generation and fourth-generation aircraft.

After a long time, the fighter, although it looked relatively well preserved, some of the fragile metal inside had been severely aged and corroded, and it had been completely scrapped.

It doesn't matter, this fighter is the most valuable to Chen Rui, for all countries, is the above beyond the era of various fighter technology, the most important one is an advanced engine technology, China has suffered enough of the engine, it is a heartache and tears, secondly, advanced weapon systems, avionics systems, navigation systems, advanced aerospace material technology,.

If Chen Rui is willing to sell this fighter, the United States, China, and major powers will rush to ask for it even if they spend hundreds of billions of dollars, trillions of dollars.

Of course, Chen Rui will not sell this fighter, perhaps, in the future, the fifth-generation fighter will be the first to soar in the sky on Tortuga Island, and the whole world may be sluggish.
