Russia and exposure People’s Liberation Army underground cavern full of big guys
Portal width, the length of the hangar between the Portal, cavern capacity and other parameters according to the number of underground airport, in general can be inferred, known in the Chinese Air Force 17 F -4, strong -5 , J-6, F-7, F-8, such as the J-10 fighter cavern can accommodate 683-723 aircraft F -10, both linked to the minimum distance of 16 meters, accounting for the Chinese Air Force active duty and plans to service F – 10A/B/S aircraft three-quarters of the total; 14 H – 5 bombers cavern can accommodate up to 600 H – 5, enough to park all active in the Chinese Air Force H–5 bombers. You can also park 544 F -20 668 J-11.
According to the Russian Military Review reports, pictures and media information has been exposed, the Chinese Air Force more than 40 underground construction of the airport all the hillside, cavern door width between 12-40 m , is divided into three types, can accommodate more than 1500 combat aircraft, including 17 fighter caverns and 14 H 5,7 H-6 bombers cavern.
Russian media said found more than 200 military, civilian and dual-use airport towards airport construction has been a high standard strict requirements, especially for a certain type of airport runways, taxiways and apron is always the same. The
from the exposure image and the media disclosure of information
in the construction of a military airport fully learn the advanced experience of foreign countries, the majority of military airports to select the 1950s, the WTO is very reliable fighter Airport for the standard model, and the Warsaw Pact countries, especially the Soviet engineers , played a key role in the Chinese military airport construction project.The
Russian media said the Chinese Air Force underground airport usually has a main runway with parallel taxiway is often used as alternate runway. The main difference of the Air Force ground and underground fighter base is usually the intergenic region and the existence of the underground cavern. Underground hangar fighter base is basically not to use the taxiway and intergenic regions, but the base will have two taxiways.
underground apron diameter usually is 23 to 30 meters, can be parked three fighters. Concrete pedestal in front of the cavern is usually 14 meters wide. Less typical of the Chinese Air Force base in Quzhou cavern in front of the concrete pedestal and taxiway together, enemy bombers in order to destroy the taxiway at least several times fighting to enter.
aviation base in the shape of the traditional style of
generally like a horseshoe, the use of the apron around the underground machine nest, able to withstand the low-flying missile-bomb attack. This decentralized deployment of fighters and H-5, H-6 bombers underground base in China is very common.
However, the presence of a large number of remote high-precision cruise missiles is basically offset by the advantages of this decentralized layout, separate apron high-precision weapons to destroy a high probability. Horseshoe-shaped or linear layout of the airport in the attack, the enemy without having to use too many missiles, can easily cut the links between aircraft and the runway.
Although this defect by way of an additional taxiway to make up, but it can only reduce the number of aircraft damaged by explosion and fire.
Russian media said recently, some traditional Chinese Air Force base through the addition of a high protective aviation bunker can be further reinforced, very much like the United States and NATO TAB- V bunkers, the main symbol of the taxiway and apron camouflage finish, apron top of the cover it with dust, in order to strengthen protection.
, however, still no evidence that this high-strength reinforced concrete bunker able to withstand the destruction of high-precision ground-penetrating bombs, such as the BLU-109/B, BLU-116/B, BLU-118/B and The GBU-39/B bomb. U.S. Air Force in Okinawa, Japan, the high protective TAB-V aircraft shelters could not resist the blow of the giant earth-penetrating bombs. Do not have enough troops, even with modern weapons and equipment we will be too much.
Russian media said the Chinese Air Force air base of the underground hangar in the topography and geology permit, hillside, if there is no underground hangar, only because of the surrounding mountains, mountains or hills did not meet the conditions. The terrain is very flat in most parts of the eastern coast of mainland China, mountains, hills and mountains visible at any time, very suitable for the construction of underground airport.
Chinese Air Force is in these places in the area of ??Shenyang, Beijing, Jinan, Nanjing and Guangzhou Military Region Air Force built a majority of underground hangars. The layout of these caverns different engineers in the design of these underground facilities as much as possible to make full use of terrain, determined according to the characteristics of the flat terrain of directly approaching hills runway layout, the results of some of the runway from the cavern a few hundred meters, some distance of several kilometers, which will naturally have a combat aircraft quickly take off to have a greater impact. Chinese helicopter manufacturing history can be traced back to the 1950s, the Harbin Aircraft Manufacturing Factory, in 1956 the Soviet Union help license production m -4 helicopter, code-named Straight -5. After the name of the majority of helicopters in China to the Chinese character for “helicopter” the first Chinese character for “direct” number.
underground air base on the taxiway or an additional runway has assisted take-off area, and usually with a hangar door is directly connected. This hangar in front of a concrete pedestal, or only a few hundred meters from the main runway, the aircraft taxiing off rapidly change calm.
return aircraft will be landing in the main runway, then taxiing or towed back to the underground hangar. Under normal circumstances, concrete pedestal middle of the same auxiliary runway to ensure that the plane took off and return to the hangar. This auxiliary runway than the standard taxiway width and straight. Individual airport’s secondary runway status is not good in some places overgrown with weeds.
Russian media said the Chinese Air Force underground hangar door and taxiways are usually opposite, built about 200 meters away, which naturally exposed the location of the cavern door. An underground airport is usually open two holes in the library door, using a Y-shaped taxiway. A small amount of the airport is only a hole in the library door.
individual caverns and even have a four door, such as the Nanjing Military Region Air Force Guiyang Airport and Lanzhou Military Region Air Force Yinchuan Airport. Chinese Air Force underground hangar door width ranging from fighter base cavern door is quite narrow, the narrowest part of only 12 m, H-6 bombers base cavern door width up to 40 meters.
disclosure to the Google Maps satellite images of the study found, the Chinese air base underground hangar door width is mainly used three criteria used for parking the F-4 (MiG -15) strong -5 F-5 (MiG-17), J-6 (MiG -19), F-7 MiG-21 and F-8 (MiG-23) MiG-class fighter cavern door width of 12-15 meters, parked H-5 (IL-28) bombers cavern door width of 22 meters, parking H -6 (-16) bomber cavern door width of 35-40 m.
Most common in
door width of approximately 14 m, apparently mainly for the Chinese Air Force old fighter, but can also be parked a little new F-8 and JH-7 aircraft . The reason why there is no F-11A/B, Su-27 aircraft, because of too much, this fighter’s wingspan is 14.7 meters, and can not hole.
If you want to use the F-11A/B in these underground airport, it must be modified Su-27K, Su-33, -15 F to use the folding wings, or production wingspan and related tunnel width fairly new aircraft, or to expand the tunnel. As for China the F -10A/S/B new combat aircraft, the wingspan of only 9.7 m, fully able to use all underground hangar. With Western modern gas turbine helicopter production experience, China’s aviation manufacturing division based on the development of domestic helicopter in the late 1990s started to develop a domestic army anti-tank helicopter gunships straight -10.
the latest 5th generation fighter F -20 prototype you need folding wings, or change the wingspan of less than 14 meters. Door width of 22 meters underground hangar apparently in order to park a wingspan of 21.5 m H – 5 bombers were built.
of course, can also park the F-11A/B, Su -30MKK/MK2, and F -20, rather than the aircraft or tunnels to make any changes. The hangar door width of 33-40 meters in the underground base of the Chinese Air Force to ensure that parked H-6 bombers, and all dimensions smaller number of aircraft.
Russian media said, should be recognized that the public media to grasp the picture is very little detailed information about the internal layout of the Chinese Air Force underground hangar basically not known to the public. Given the special nature of the cavern, its internal layout, there are many possible. Majority of the underground hangar airport no external hangar, aircraft engineering and technical maintenance is usually also in other places.
underground hangar layout of the internal fighters and aircraft carriers configuration is similar, but the aircraft carrier hangar is usually wider than the underground hangar. Underground hangar is the most simple internal layout of the Chinese Air Force is in the straight, curved or arched tunnel to open the portal, connected to two before and after the parked aircraft in accordance with the end to end.Beijing Shahe base,
only open to the public on the use of this layout, the Portal between the total length of the hangar for more than 500 m, at least for connected end to end parking 12 H-6 bombers , which is equivalent to the number of the establishment of a standard Air Force, Chinese Air Force combat aircraft. If this layout is the standard configuration, then by the straight-line distance between the Portal has a rough assessment of the internal capacity of the hangar.
most airports cavern length of 500 meters or so, may grow up to 1000 meters in some places, some places may be only 300 meters, the average total capacity of 3200 m3. Thus, although in the case of the lack of an open layout diagram to assess the capacity of the Chinese Air Force underground hangar there are some difficulties, but can still picture analysis of Google Maps exposure rough guess.
Of course, the absence of detailed internal layout information and do not know the hole bank a few minutes the hole, there is no parallel to the tunnel, estimate the figure may be lower than the actual capacity.
Russian media said one of the few photographs I have seen the Chinese Air Force underground hangar may they use a simple layout, Portal, and the shape of the hangar is a shape, L-shaped, U-shaped and S-shaped. Used for parking the F-11A/B, Su -30MKK/MK2 F -10 F -20 fighter planes and bombers -5 cavern layout the H -6H/M/K/U bombers are not the same, but the overall layout not a big difference. A few years ago, the Russian news agency disclosed that China and Russia signed a cooperation agreement in March 2007 set up a joint venture in Chengdu, Sichuan Blue Sky Helicopters Ltd., responsible for the maintenance and assembly m -171 helicopter.
, according to the number of underground airport Portal width, the length of the hangar between the Portal, cavern capacity and other parameters can be in general speculated that the Chinese Air Force 17 known F-4, Q – 5 , J-6, F-7, F-8, such as the J-10 fighter cavern can accommodate 683-723 aircraft F -10, both linked to the minimum distance of 16 meters, accounting for the Chinese Air Force active duty and plans to service F – 10A/B/S aircraft three-quarters of the total; 14 H – 5 bombers cavern can accommodate up to 600 H – 5, enough to park all active in the Chinese Air Force H–5 bombers.the
can be accommodated 544 F -20 668 J-11 J-11, both linked to a minimum spacing of 14 m, F -20 minimum spacing of 19 m; 7 H – 6 bomber cavern could accommodate 138-145 aircraft bombers -6, both linked to a minimum spacing of 36 meters, enough to deploy all of the media, the Chinese Air Force active duty 120 H – 6.
Of course, the Chinese Air Force in the H – 6 holes library parked fighter, with a capacity of 10 H-6 of the cavern can accommodate an aviation regiment prepared 36 Su – 27/30 fighter aircraft. In addition, at least three known underground hangar rarely, in the end be able to park the number of combat aircraft, it is difficult to make reliable estimates.
but, even so, once the Chinese mainland was attacked, the Chinese Air Force can at least hide in the underground hangar over 1500 combat aircraft, to resist the enemy’s first round of the fatal blow, to save a considerable considerable strength, and then resolutely fight back. With continuously strong rise of Chinese economic and military irreversible.
