Fan Wuxian has always been very concerned about the combat situation of the US military in Afghanistan, which is not to say that he is ready to engage in military command research, but because now that he is a big arms dealer, it is necessary to understand the modern combat mode of the US military so that he can develop all kinds of weapons that can compete with the US military equipment.

Therefore, on Christmas Eve, Fan Wuxian inspected the Southeast Heavy Industry Group.

Originally, he wanted to take the opportunity to meet Ouyang Xiaowei, who was in charge of important information liaison work in the Southeast Heavy Industry Group, but unfortunately he only learned after passing over that because of some things in the General Armament Department and some things in the military, Ouyang Xiaowei just left here and went to the capital.

"What a mistake—" This made Fan Wuxi feel a little regretful.

Among the technical personnel of the Southeast Heavy Industry Group, in addition to some of their own people, there are many experts supported by the military, and some are professional soldiers who specialize in the study of modern war weapons, but now these people have taken off their military uniforms and appeared in the Southeast Heavy Industry Group as civilian people, and everyone has become engineers.

Overall, the paramilitary management in the Southeast Heavy Industry Group still made Fan Wuxi feel some of the atmosphere of being in the barracks, at least the factory guards with loaded guns and the light and dark sentries cleverly hidden in various positions in the factory area, as well as the ubiquitous electronic eye monitoring system, made Fan Wuxi feel that this was really not an ordinary factory.

In fact, Fan Wuxian suddenly came to inspect, Southeast Heavy Industry is still a little uncomfortable, because since the establishment of the factory, no one has ever inspected the key departments here, and the external propaganda is also to say that Southeast Heavy Industry Group is a private enterprise mainly engaged in the production of auto parts, and it is a very ordinary key enterprise that provides services for several large domestic automobile enterprises.

Therefore, the previous inspections of local leaders only led them to those peripheral links that were not very important to take a turn casually, at this time Fan Wuxian came over in person, naturally he would not go to see those irrelevant things, he directly wanted to see the core production of the research and development link.

In this way, it poses a huge challenge to the confidentiality system of the enterprise, because according to the current situation, Fan Wuxian has been engaged in behind-the-scenes operations, although the chairman of the Southeast Heavy Industry Group has never appeared in the factory area, and when he first came over, the guards in the key military industrial area did not let them in at all.

"The boss can't go in either?" Fan Wuxi felt a little entangled, and said in his heart that this system was a bit too much, and no one could limit himself.

The leaders of the enterprises who accompanied him said that because there are some military projects, they still need to get the approval of the military to visit these laboratories and production workshops.

"Originally, when Miss Ouyang was there, she was in charge of this part of the work, and she was directly able to approve whether visitors could enter on behalf of the military, but now she happens to be away, so it's trouble-" One of the deputy general managers who accompanied her explained to Fan Wuxian.

Fan Wuxi patted his forehead and said with a smile, "This matter is done, then contact Ouyang." ”

contacted Ouyang Xiaowei, Fan Wuxian chatted with her for a few words, and then explained the current situation.

"Hehe, who made you never come to the factory to see me, of course you can't come in now." Ouyang Xiaowei smiled, and then said that he would add Fan Wuxi as an exempt person to the safety management system of Southeast Heavy Industry, so that he could inspect the work of the enterprise at any time.

After doing this for a while, the company's security network finally added Fan Wuxi's personal information, which is the highest level of security, and can visit any laboratory and production workshop, and has some corresponding temporary disposal permissions.

Of course, if you want to exercise the chairman's authority on some major issues, you still have to go through the right procedures, after all, although Southeast Heavy Industry is a private enterprise, but because it involves the top secrets of military production, it has to be stricter.

During the visit, Fan Wuxian saw the fire control system, laser guidance system and computer self-positioning system on the domestic infantry self-propelled artillery and the new tank that were already in formal production, and saw the actual effect demonstration, which was really a very advanced technology, which opened his eyes and expressed high praise.

In several laboratories, we have also seen several projects that are being developed intensively, such as fighter stealth and anti-stealth technology, laser-guided bomb devices, and some equipment for the disintegration of airborne early warning aircraft systems on large aircraft.

The stealth technology and anti-stealth technology of the fighter plane seen this time are actually not unrelated to the last time the Americans bombed the embassy.

At that time, because of the important parts and external composition materials of some US stealth aircraft, these things were sent to several research institutes of the military for decompilation, and some results were also achieved.

"This work is also very important—" Fan Wuxian looked through the floor-to-ceiling glass compartment as the staff were busy doing various analysis tests inside, and nodded to the people around him who accompanied the visit.

Fighter stealth is a big problem, and at the same time, this technology can also be used in other aspects, such as the stealth technology of maritime ships, which is mainly for the detection of aircraft or radar for stealth, which is very useful.

In terms of anti-stealth technology, the laboratory side is conducting combat tests of passive radars.

In fact, in the face of the continuous proliferation of stealth technology of US fighters, countries around the world are seeking solutions to counter stealth technology, and one of the technologies is low-cost and efficient passive radar.

Passive radar is a pure receiving system that uses external radiation sources, and the passive radar receiver is laid out in a network pattern, which can detect, track and target manned and unmanned stealth systems after forming a comprehensive system, and guide air defense weapon systems to attack them. Passive radars do not emit radio signals and can be closely camouflaged in urban and rural terrain. The attacking system cannot receive any hints of passive radar reconnaissance signals from friendly radar warning receivers, so it is difficult to determine the location of such radars and attack them.

In the face of the threat of passive radar, although the US military has advanced stealth technology, it also finds it difficult to seize air supremacy at an acceptable cost in the future.

At present, the rapid development of passive radar technology has made it impossible for the US military to use traditional means to destroy the opponent's air defense system, so when facing an opponent equipped with passive radar, the US military will also find it more difficult to seize air supremacy.

In World War II, the overwhelming offensive power of aircraft was seriously weakened by radar and modern air defense systems, air power is not an invincible all-round offensive weapon, bombers often cannot break through the enemy's air defense system, the air defense systems of both the Axis and the allies are advanced and very flexible, and combat aircraft can only gain partial air supremacy by destroying the enemy's air defense system at a great cost, and this situation lasted from World War II to the Cold War.

Although a technical breakthrough was made in the test of passive radar at that time, there were also some problems, including the signal strength was sometimes strong and sometimes weak, because the geometric arrangement of passive radar could not determine the position of the target, and the tracking of the target was uncertain. Passive radar is a kind of transceiver separate radar, which means that there is a certain distance between the receiver and the transmitter, and scientists configure the receiver and transmitter by sharing antennas, thus solving the problem of geometric arrangement, that is, monostatic radar, which was later adopted by general-purpose conventional radars.

Radar is the basis of air defense combat systems, such as in the Vietnam War, the North Vietnamese army used air defense radar to target US fighters, and US fighters jammed North Vietnamese radars and fired anti-radiation missiles. Due to the successful organization of air defense in North Vietnam, the United States could only temporarily establish air supremacy in parts of North Vietnam. During the Vietnam War, North Vietnam used Russian surface-to-air missiles in the fifties to shoot down nearly 200 U.S. warplanes.

However, after the seventies, Lockheed Martin's Skunk Works began to develop the F-117 stealth fighter. The F-117 took up combat duty in 1983 and later participated in combat operations in Panama and participated in the Gulf War. During the Gulf War, the U.S. Air Force used F-117s to attack Iraq's most heavily defended targets. Despite Iraq's powerful air defense system, the US Air Force did not lose a single F-117 fighter in the Gulf War.

In comparison, 32 non-stealth warplanes of the US military were shot down by Iraqi anti-aircraft artillery or surface-to-air missiles.

In fact, in the wars that have been waged in recent years, including the Allied operations in 1999 and the recent US military operations in Afghanistan, the US military's stealth planes have maintained an overwhelming superiority.

Despite the overall success of the U.S. stealth program, the year before last, a U.S. Air Force F-117 was shot down by a Serbian surface-to-air missile over the Balkans. While some believe that the downing of the aircraft was just an accident, the incident has caused controversy, with some arguing that it is a proof that stealth technology has been defeated, an incident that shows that stealth technology does not make the aircraft invisible, it is just a technological game.

But in fact, Fan Wuxian is more aware of this, but a grating information feedback system used on the ground is actually very passive, if it were not for the fact that the US fighter plane was too carried away and the round-trip trajectory was recognized by the ground forces, or this F-117 was unlikely to be shot down.

In order to completely break the stealth technology of US fighters, this passive raster scanning system alone is obviously not enough.

There are no pop-ups
