Events: Russia: new weapons, two People's Liberation Army caused panic in the United States Army
| Event Details:
[Abstract] Russian claims that China began to experiment with their fifth-generation fighter J-20, and some people call it the J-14 and J-XX. January 11, 2011 J-20 completed its first flight. The incident caused a panic the U.S. military. For example, U.S. Defense Secretary Robert Gates • an official visit to China shortly after that, U.S. intelligence on China's growth rate and level of equipment underestimated. He said that China's DF-21D anti-ship ballistic missiles and J-20 is particularly disturbing.

According to the Russian bond news report, China's fifth generation fighter J-20 prototype developer of who is suspected of copying the U.S. F-117 "Nighthawk" stealth fighter-bombers on the use of technology. Some experts say that Chinese agents may be purchased from Serbia during the Kosovo war of 1999 F-117 downed aircraft wreckage. Interestingly, the Chinese copy on to say that U.S. technology proposed by the Croatian army.
Lockheed - Martin Corp. F-117 "Nighthawk" fighter-bomber, the Air Force in 1993 and fitted out, which is the world's first stealth fighter. The maximum flight speed of 990 km, mainly geometric stealth technology, each part of the fuselage radar reflected radio waves will not return to the radar receiver, this is the aircraft fuselage with a bizarre and unique form of reason.
In addition, the aircraft structure using the heat-absorbing ceramic plates, used to reduce the aircraft's infrared detectability, but also using composite materials and the absorbing material. Various parts of the aircraft fuselage serrated interface, which is directly in order to prevent electromagnetic energy along the direction of the radar antenna reflector back. It is said that these technologies make it difficult to aircraft penetration was found.
90's of last century the new technology effectively in the battle to what extent can continue to argue. F-117 a total volume manufacturing of the 59 (plus the prototype is 64), lost in actual combat only one. Need to be reminded that, in the Kosovo war, the number 82-806 of an F-117A was from Serbia Zuoer Dan command of Colonel Daniel • 250 air defense brigade belongs to 3 with the S-125 "Pechora River "air defense missile system shot down.

NATO command was explained, F-117A was the main reason for S-125 shot down by Serbian anti-aircraft missile systems long-wave, while the F-117A is designed for the modern short-wave radar. Because of this defect, the Serbian air defense weapons to be found and brought down the world's first stealth fighter. Then there is a saying that, F-117A stealth of the radar is not aimed at the transmitter and receiver antenna case of the two places, while the Serbian air defense system is this.
Zuoer Dan himself later said, has been able to successfully shoot down F-117A, due to too much faith in the U.S. Air Force F-117A stealth performance, and to ensure that the aircraft did not take basic security precautions. U.S. aircraft at the scheduled time for combat flight along the same route, so Serbs can shoot down one of them. The U.S. has since changed the flight the aircraft.
Another factor is the favorable Zuoer Dan resourceful commander. Zuoer Dan radio silence in order to ensure a series of measures taken. He knew that NATO forces be able to immediately intercept electronic surveillance in connection with its missile radio, which organized the cable communication system. In addition, the Serbian radar and launcher constantly changing positions, increases the difficulty of the enemy found them.
F-117 aircraft were shot down and wreckage scattered over a large area in the region. Including the canopy, the pilot helmet and some fragments of the wing of some aviation museum in Belgrade is currently on display. The remaining fragments collected by local residents and as souvenirs away. According to reports, April 30, 1999 F-117A was also a Serbian anti-aircraft fire hit, but it can be returned to base. Since then, the fighters said to never fly.
Following use in Yugoslavia, the United States in 2001 and 2003, respectively, in Afghanistan and Iraq with the F-117 has successfully carried out the bombing. U.S. Air Force in 2008, the F-117A retirement on the grounds that the use of cost is too high, driving problems, the other more advanced F-22 fighters have entered active duty. At present, only a few F-117 aircraft still in test flights.
The end of December 2010, China began to test their fifth-generation fighter J-20, and some people call it the J-14 and J-XX. January 11, 2011 J-20 completed its first flight. The incident caused a panic the U.S. military. For example, U.S. Defense Secretary Robert Gates • an official visit to China shortly after that, U.S. intelligence on China's growth rate and level of equipment underestimated. He said that China's DF-21D anti-ship ballistic missiles and J-20 is particularly disturbing.
Although the U.S. defense budget for the next five years is reduced overall, but in order to successfully confront the threats from China, Gates decided to increase the funding of several military programs. Among them, the budget increase in 2009 related to termination and should be restored in 2012, a new generation of long-range bomber development program, the new ship-borne radio-electronic suppression equipment development work, and F-35 aircraft carrier project.
At the same time, J-20 began to experiment not only make the United States fear, but also make the United States surprised. To know that China not only failed to develop stealth aircraft technology, not even a reliable high-power engine, while the shoulder with the U.S. F-22 performance and the Russian T-50 fighter-bomber project than shoulder suddenly turned out. Western military experts rush to accuse Russia and China "share" and the design of stealth aircraft technology.
Indeed, all such statements are likely to be speculative. Russia and China previously did "share" some technology, but very limited. Among them, China has permitted some Russian fighters assembled at the same time, copy the aircraft and power plant. At present, China is actively promoting J-11 fighter aircraft of foreign - Russian Su -27 imitate, but both the aircraft itself or the former power plant of its life were significantly lower than the original product. Indeed, prices of Chinese aircraft Russian aircraft is much lower.

Today, the focus has shifted to the United States from Russia. 1 January 2011 21 Analysis of `site G2Bulletin published material shows that American companies during the Clinton administration, Bill • generously shared with the Chinese developed the field of aircraft technology and technical secrets. BP U.S. companies to China in which the transfer of the composite materials and precursor materials technology, Hexcel Corporation provided China with pre-impregnated composite materials technology, and the transfer of the Sikorsky aviation gasoline component production technology and aircraft fuselage shape calculation.
Site in accordance with the conclusions of G2Bulletin, China successfully mastered the technology and be combined, for the development of advanced weapons, including stealth cruise missiles, a new generation of fighter aircraft, warships, and with low detectability of ground technical equipment. The U.S. military did not yet comment on the report. Should be noted that on several occasions in U.S. history, with many countries signed a military technical cooperation agreement, within the framework of these agreements carry out various projects within a reasonable share of their technology.
Later, he participated in the former Yugoslavia, Croatia's military operations in sub-Davao • General Duomazete - Velloso speculate that China could develop its own process of J-20 F-117A in the use of technology. He said that according to intelligence agents active in China, farmers from Serbia to buy the F-117A wreckage, some of which fragment size and the "car" quite. He said: "We believe that the Chinese people to get the concept of secret technology ... ... the use of these materials and transform them."
January 24, 2011, The Associated Press quoted an unnamed senior military officer as saying that Serbia, the foreign intelligence agents to the farmers who actually acquired the downed F-117's wreckage. Meanwhile, in Rome's military adviser, Zoran • Kusuowaqi speculate on the downed F-117 study may in the Russian T-50 fifth generation fighter aircraft's development process has also played its own role.
Meanwhile, Kusuowaqi apparently forgotten in the development of the U.S. F-117 when the active use of the Russian physicist Peter Zaitsev • Wu Feimu 60s of last century in its scientific monograph "methods of physical diffraction," expounded the idea in the . Wu Feimu Zaitsev presented in this work plane of the radio wave reflection theory. Wu Feimu Zaitsev since 1990 working at the University of California, and with Northrop - Grumman B-2 bomber in the development of cooperation within the framework of the project.
About China in the development of J-20 may use the technical declaration F-117 overall look is not convincing. The Pentagon believes that China is strong enough to develop intelligence, is fully capable of "stealing" some of the foreign technology is not complicated - not to mention stealth geometry theory, which in itself is not any great secret. The use of well-known theoretical calculations and the development of not only stealth, but also the aircraft can fly more complex.

The United States in the development of fourth-generation fighter F-117 attaches great importance when the first stealth, but paid the price for loss of flight performance. Because different body, the U.S. aircraft difficult to control, mobility is poor, can not break the sound barrier. F-22 later in the development process, the United States try to aerodynamic performance and stealth aircraft to find a compromise between performance. Fifth-generation fighter aircraft rely on the front section to achieve stealth.
In addition, should also not forget that any technical equipment, even non-military technology and equipment, if there is no technical information, do not use the same production technology, are difficult to imitate. You know, imitation is not enough aircraft shape, but also need to know what materials to use, how to assemble, how to use. China has copied the Russian АЛ-31Ф and РД-93 engine many years, but the imitation of life and reliability in fact only half of the original product.
F-117 material used in the development process as well. F-117 fragments may fall into the hands of Chinese agents, no doubt about it. Neighboring countries have the advanced technology of their own interest. It is hard to believe that China has successfully copied the U.S. plane absorbing materials, composites and ceramics components, although not exclude the possibility that this attempt.
For example, as early as mid-2010, the Internet appeared in Chinese-made copies of F-117 fighter satellite photos. The plane parked in a military enterprise Luoyang plant. As to whether China is mass production of the aircraft, there is no any news.
U.S. Air Force has stated, F-117 and J-20 have nothing in common. In any case, if China succeeded in opening a secret F-117 and J-20 used during the development of these secrets, these findings did not give the Chinese technological superiority. Because since then, combat aircraft stealth technology and the development of technology has made significant progress. The United States has equipped the F-22 fighters and is developing the F-35, while the latter uses a new material. Therefore, based on the principle of development of F-117 aircraft in any case, China will lag behind the U.S. and Russian fighter jets at least ten years.
A national of another country based on technology developed fourth-generation fighter's ability to fifth-generation fighter has been very suspect. To know the characteristics of a new generation of fighters is not only famous stealth - Today's soldiers, the military industry in the production of socks only when not using it. New fighter also has a complex airborne electronic equipment, radar systems and weapons, super maneuverability, supersonic cruising ability ... ...
In short, to develop performance and F-22 or T-50 fifth generation fighter aircraft rather, China must complete a breakthrough in several areas, including electronics, materials science, program design and aerodynamics. In addition, there must be a wealth of experience in aircraft design. Otherwise, there are big countries can boast that they have the fifth-generation fighter aircraft.
