India plans to purchase 6 new generation of submarines 300x195 India plans to purchase 6 new generation of submarinesIndia plans to spend more than 5000 billion rupees (1 U.S. dollar equals 46 rupees) purchasing six new generation of conventional submarines to replace the aging submarine fleet.

According to “The Times of India,” 11 reported that the heavily procurement led by the Indian Defense Minister Antony Defence Procurement Board. 6 new generation of submarines in the four countries will provide technical assistance to build in India the other two are likely to buy from abroad, but may also by the Indian private shipyard.

Reported that six new generation of submarines will be equipped with modern combat capabilities, including stealth, attack coastal targets, and so long submerged.

The aging of the Indian Navy‘s submarine forces seriously. “The Times of India”, said by 2015, 15 conventional submarines on active service may be able to use only half. In 2005, India had signed a contract with France, from France to help India build six French “Scorpene” class submarine. However, prices and other factors, the first one, “Scorpene” class submarine is likely to be postponed until 2014 before delivery.

Japan 22DDH is a serious threat to China’s submarine

Jul 6

Japan 22DDH 214x300 Japan 22DDH is a serious threat to Chinas submarineWhy does Japan have repeatedly Qingli large deck type ship built? Does this mean that Japan’s defeat in World War II aircraft carrier again after the recovery of their dreams?

Recently, the Japanese Maritime Self Defense Force agreed that the third ship “helicopter destroyers” will be the relative size and capacity have been served “on the” class helicopter carrier, a major improvement. New 22DDH ship more than 24,000 tons displacement, which makes it almost more than 16DDH “day to” level the size of the helicopter carrier is 50%, so difficult to use the “destroyer” to refer to those ships. Taking into account the size of ship, with the United States during World War II, “Essex” class aircraft carrier in comparison. Why is Japan again Qing Li built a large deck type ship? Does this mean that Japan’s defeat in World War II aircraft carrier again after the recovery of their dreams?

Carrier after another big ship

In 22DDH helicopter carrier, Japan had a continuous manufacturing and service the two types of large ships through the deck, which is known for long, “Osumi”-class landing ship and helicopter transport 16DDH “on the” class helicopter destroyer.

In service since 1998 “Dayu” class landing ship helicopter transport links with all the deck starboard island structure, the standard displacement reached 8,900 tons, Captain 178 meters long, and nearly 26 meters wide, can carry 1,000 Marines, 16 CH -47 heavy-duty helicopters, 10 Type 90 main battle tanks and 1,400 tons of material, two large air-cushion landing craft. Although the Japanese to “Dayu” level as the transport landing craft, they have deliberately conceal class aircraft carrier combat. But it was through type flight deck and aft deck structure can be proved beyond the normal landing craft ship capacity, the potential function of an aircraft carrier, is “quasi-carrier.” “Dayu” class landing ship transport aircraft carrier in Japan has really laid the foundation for a number of militarists in Japan that “Dayu” number service, marking the Japanese aircraft carrier of the comeback. “Dayu” class landing ship transport service, the Japanese Maritime Self-Defense Forces are not satisfied with such a “quasi carriers,” starts on a new aircraft carrier.

In 2004, the Japanese Maritime Self-Defense Force began building 16DDH “on the” class “helicopter escort.” The first ship “on the” number, in August 2007 and launched service in March 2009. Second ship “Ise” was also launched in August 2009, is expected to serve in 2012. The ship deck using all-pass starboard island structure, the standard displacement of 13,500 tons, can carry up to a total of 11 helicopters of various types, can be parked on the flight deck 4, hangar seven, while allowing four helicopters can take off and land. Although the Japanese call it “helicopter escort,” but ship is fully equipped to be a light aircraft carrier with all the features, according to NATO standards is actually a helicopter carrier.

Japan’s Maritime Self-Defense Forces “day to” was launched when the helicopter destroyer had the U.S. media exclaimed: “This is the first one in Japan after World War II aircraft carrier.” Many military experts also believe that “day to” was able to slightly improve the carrier’s new faces join the ranks of Japan’s Self-Defense Forces. But the United States, “Defense News” quoted the Tokyo Institute of peace and security, the President as saying, “The new helicopter destroyer deck is too thin, F-35 can not withstand the pressure of landing.” Helicopter carrier that has a 195 m long straight flight deck, can withstand 33 tons of large-scale helicopter transport MH-53E “Sea Dragon” movements.

For the construction of the new 22DDH Japanese helicopter aircraft carrier, the superstructure and the “day to” class helicopter carrier, similar to the difference is surrounded by 01 deck extension, deck area increased by nearly one-third of the total, can be large enough to accommodate vertical launch air defense missile system. And “day to” class helicopter carrier, the new ship’s point defense capability beyond its double, which is equipped with four MK15 “Phalanx” The gun and two “Ram” short-range defense system launchers, The “day to” level is only equipped with two “Phalanx” The gun.

Japanese financial project that, 22DDH dramatic increase in ship size design one of the reasons is that Japan plans to V-22 “Osprey” tilt-rotor aircraft as a major air forces of these ships. In addition, 22DDH ship’s design also includes consideration of operating unmanned aerial vehicles.

Anti-submarine helicopter carrier lies

Since the post-war Japanese economy recovered from the post, began to wait for an opportunity to seek revival of its aircraft carriers Dream, “Day to the” issue of the construction of aircraft carriers is the first step put the plan into action. More military experts believe that as long as Japan are US-made F-35B Short / vertical takeoff and landing aircraft, immediately will be able to “day to” was converted into a real aircraft carrier. Moreover, as long as the time is ripe, “Japan to” level and “Dayu” level can be in the “converted into an aircraft carrier within two months” to form a new carrier battle group. Military strategy experts pointed out that the future development of the Japanese aircraft carrier program, and the United States is not without relevance. 50′s of last century, the Korean War with the United States of support and opportunity, the Japanese took the opportunity to “revive” its own military forces. However, the U.S. has no intention to build a Japanese Maritime Self-Defense Force to undertake operational tasks independently powerful sea power, but to as a “small attendant.”

So, the construction of so many big Japanese navy helicopter carrying capacity with a strong surface ships, is for what? The answer is: the implementation of ocean-going anti-submarine mission. Soviet hegemony in the Cold War era Soviet submarine fleet in order to prevent conflict into the Pacific, the Japanese Maritime Self Defense Force in the United States, Japan anti-Soviet Union, to carry the heavy anti-submarine pioneers. After the Cold War, the Russian Pacific Fleet, shrinking, growing Japanese patrol area will be expanded to the South China Sea, the strategic task to contain China’s submarine into the ocean. Japanese shore-based anti-submarine combat radius is limited, so the helicopter carrier have come into being, “Dayu” class helicopter carrying a total of four, 16DDH can carry 11 helicopters, 22DDH will carry at least 14 helicopters, mainly SH-60K “Hawk” anti-submarine helicopters, as the fleet’s flagship ocean anti-submarine warfare, to join the existing fleet of “19″ fleet, may be anti-submarine combat capability to double to cover the area have increased several times.

Japanese prefer to give these helicopters contains a selection of the V-22 “Osprey” tilt-rotor aircraft, a model for the SV-22 anti-submarine model, the model is the U.S. Navy plans to replace the S-3 “pirate” ship-borne anti-submarine aircraft general aircraft type. Reached its maximum combat radius of 1205 km. SV-22 will be equipped with hanging sonar, magnetic anomaly detectors, sonar buoys and Mk-50 anti-submarine torpedoes. As the V-22 “Osprey” aircraft superior short-range vertical takeoff and landing performance, so that it can carry anti-submarine equipment, more and more comprehensive, and therefore a greater range of anti-submarine capabilities and patrolling. As the world’s second-largest anti-submarine power of Japan, this would have more than 100 fixed-wing aircraft of advanced anti-submarine patrol aircraft, plus “19″ Fleet-class anti-submarine capabilities, and then join the group if the helicopter carrier’s carrier aircraft, That is really an even more powerful of Japan’s maritime anti-submarine warfare.

Break the bottom line deterrence neighbors

The construction of aircraft carriers in Japan as the biggest obstacle to peace in the Constitution from the domestic constraints, followed by the United States can not allow Japan to build a large attack aircraft carriers, is another who has suffered from Japanese aggression in Asia over the country will not allow Japan to build a real aircraft carrier. But also see the world, though Japan’s pacifist constitution limits have realized they still sending troops overseas, Self-Defense Force ships are openly patrolling in the Gulf of Aden and began to build Zhubo base, also to upgrade the Defense Agency Ministry of Defense and so on. Driven by this trend, if one day, tear up the constitution of Japan, a large-scale production of attack aircraft carriers, nuclear submarines and intercontinental ballistic missiles, is also very possible. Particularly in the current U.S. military rising because of China, worried about the destruction of their Western Pacific strategic balance of Hua, the Keneng to open one eye close one eye to the default strategy of self-Fa Zhan Japanese aircraft carrier force, in particular for the parent type is 22DDH improve the most likely to attack aircraft carriers. This occurs when the sovereignty dispute between China and Japan, the Chinese navy’s submarine force as a large number of in wartime combat forces out of the first island chain, Japan’s powerful anti-submarine force will face checks and balances. Japanese construction 16DDH and 22DDH helicopter carrier on the Chinese Navy submarine force will be the threat of death.

Whether the construction of these vessels in Japan What is the purpose, but you can believe that neighboring countries will not stand idly by: Japan to improve the anti-submarine capabilities and remote combat capabilities, countries would have hidden under the capital increase and the submarine offensive, South Korea and other countries GM will build a more active type deck landing ship and related marine ships, South Korea’s “Dokdo” was obvious examples.

The Japanese both cunning and clever, while in calling for the “aircraft carrier China threat” theory, it already started building his own hands while the aircraft carrier battle groups, and possession of a large head and hide my face to call the helicopter destroyer. At this point, even the United States, Russia have been the calculation of the Japanese “sneak” to deceived. Japan defeated the old, will be inadvertently carrier power, and become a threat to neighboring Asian countries, a strong naval force.

The face of U.S. satellite reconnaissance submarines, Chinese submarines in the surrounding shallow sea “can not hide”

Jun 8

Posted by admin in Defense Report, Navy | Comments off

U.S. fast Bird reconnaissance satellite 300x300 The face of U.S. satellite reconnaissance submarines, Chinese submarines in the surrounding shallow sea can not hide“China, more and more difficult to hide a submarine.” According to Hong Kong, “Asia Times” recently reported that the Navy is satellite technology to track the hunter-killer submarine up in China. With this kind of “submarine reconnaissance from space,” the technology matures, becoming transparent sea, submarine operations in the sea will be difficult to cover. Currently, the U.S. Navy anti-submarine satellite is in space and submarine sonar array, sea anti-submarine ships, air anti-submarine aircraft, together constitute the three-dimensional anti-submarine network.

Satellite detection of flow characteristics of corrugated

Traditional means of detecting submarines and surface ships in the deployment of submarine sonar and other equipment, search the submarine cruising the sound issue. However, the U.S. is currently developing “Non-acoustic detection of submarine hunting” projects, mainly focused on laser, infrared, and hunter-killer satellite technology.

Satellite hunter-killer submarine in the main principle is to flow fluctuations caused when cruise to form a wake, the wake of this expansion to the surface, will form larger ripple characteristics. Deployed in satellite synthetic aperture radar can detect ripples of this feature. In addition, the submarine activities may also cause subtle changes in ocean temperature, infrared detection satellites were captured.

In fact, as early as the mid-80s in the last century, the United States had discovered the potential of satellite hunting potential. In 1984, the U.S. Navy oceanographer Paul aboard the “Challenger” space shuttle into space and successfully to detect other submarines of the ripple. “Asia Times,” also revealed that America’s “Challenger” space shuttle has performed anti-submarine missions.

May 14 this year, “Atlantis,” conducted last space shuttle flight, the crew, including Captain U.S. Navy submarine force, U.S. forces may take the opportunity to further test the potential of satellite hunting technology. In the next 18 months, the U.S. military will launch several satellites reconnaissance and surveillance satellite, which does not exclude the satellite used to detect submarines. Analysts believe that the U.S. Navy, U.S. anti-submarine into the satellite network is best for small satellites in formation flying over maritime satellite, they can be many types of detectors from different locations in space to a suspicious point of focus, better detection results.

Russia and Japan is also studying the satellite antisubmarine

According to U.S. military planning, reconnaissance and anti-submarine network should be submarines, surface ships, unmanned underwater boats, maritime surveillance aircraft and unmanned aerial vehicles equipped with exploration potential to link together as a large “underwater dynamic library” for anti-submarine forces. Currently the U.S. military is also very interested in anti-submarine high altitude airship, the project will be in the Philippines, 10 km to 50 km above the height of the deployment of radar airship to detect from the Philippines to the large area of the Taiwan Strait waters. Today, the U.S. military’s anti-submarine aircraft, anti-submarine ship and submarine sonar arrays and other equipment have formed a more complete three-dimensional anti-submarine network, satellite meant to speed up the deployment of U.S. anti-submarine anti-submarine nets are further improved.

Besides the U.S., Russia in 1991 launched Almaz-1 satellite is a kind of submarine detection satellites, can observe the underwater submarine produced in the wake. This year in April, the Russian Space Systems spokesman Boldyrev said, the company’s research center has developed a new type of satellite that can detect submarines in the deep-sea navigation. Expected that the satellite into space in 2011. Japan has the potential of satellite technology is very interested in hunting in recent years launched a number of advanced remote sensing satellite for submarine surveillance. Recent Japan in cooperation with NASA, a project also is trying to detect buoys and sea reconnaissance network, has obvious anti-submarine intent.

Technology in less than a high alert, but China should

Hunter-killer satellites in the U.S. case, in any country in the satellite detection of submarines under the “exposed.” U.S. Naval War College, Marine Institute, Chinese scholars Bide Da Dayton clear that the activities in the Spratly Islands in northern, eastern and Paracel Islands in southern Luzon Strait is very easy for the Chinese submarine captured. In the East China Sea, Yellow Sea submarine activities are faced with greater challenges, because this sea is very shallow along the coastline from China to Japan Okinawa Trough, most of the waters of the depth of only 54 meters to 109 meters.

At present, China has Asia’s largest submarine force, submarine force growth rate is also second to none in the world. U.S. Navy Intelligence Office in July 2009 released a report that China’s nuclear submarines as noisy, relatively easy to detect. The conventional diesel electric submarine has a good quiet effect, difficult to detect.

Of course, satellite anti-submarine still facing some technical difficulties. Although the satellite can detect the formation of the submarine wake, but not a long time to track. Satellite technology to compensate for the shortcomings of hunter-killer, the U.S. Navy is considering other potential means of hunting and satellite network, forming a large submarine hunting system. China should lead to a high degree of vigilance.

Kilo class submarine 300x154 Vietnam to use 3.2 billion U.S. dollars to purchase six Kilo class submarinesRussian News Agency reported on June 3, according to Russia’s “arms exports” magazine, in 2009 Russia and Vietnam signed a value of 3.2 billion U.S. dollars in 6 “Kilo” (Kilo)-class submarines purchase contract, which is the Russian Navy equipment A history of the largest export contract.

The contract was in December 2009 in Vietnam, signed during Prime Minister’s visit to Russia. According to “Arms Exports” magazine, which six “Kilo” class submarines of the construction cost of 2.1 billion U.S. dollars, but others need to coastal infrastructure, weapons and other equipment purchased to make the contract worth 3.2 billion dollars.

Admiralty Shipyard in St. Petersburg will be the rate of one per year for the construction of the six Vietnamese Navy submarines. Russia’s state arms exporter Rosoboronexport said before, Russia will be sold abroad by 2015, 40 diesel-electric submarines.

Known as “the hole” and “Kilo” class submarine is considered the world’s quietest submarine. Mainly used in the implementation of the submarine anti-submarine warfare, anti-ship warfare as well as routine investigations and patrol.

The class submarine displacement of 2300 tons, the maximum dive depth of 350 meters and the endurance of 6,000 miles, the staffing of 57 persons and is equipped with six 533 mm diameter torpedo tubes.

So far, Russia has been to China, India, Iran, Poland, Romania and Algeria to sell a total of 29 submarines of the class.

China’s new submarine combat capability with a good Mute and strong attack

Nov 20

Posted by admin in China, Military Sources | Comments off

Chinas new nuclear submarine 300x201 Chinas new submarine combat capability with a good Mute and strong attackAutumn 2009, the People’s Navy submarine force came good news: China has independently developed the successful completion of a new type of submarine dive limit, underwater high-speed, deep-sea mine warfare launched series of tests and training evaluation, etc., all the performance indicators to meet the design and operational requirements, marks the formation of China’s new submarine fully operational capability.

The birth of a new submarine, the Navy’s rally in a factory representative of the military effort and sweat. Them, with the basing of the Republic of loyalty and blood iron and steel “Blue Whale”, from the slipway towards the ocean.

Mission: To the birth of a new submarine, the new starting line sprint

One day in December 2006, the CPC Central Committee General Secretary and State President and CMC Chairman Hu Jintao, himself for a new type of submarine in the first boat out into the flag.

After the flag presentation ceremony, Hu Jintao has boarded two new submarines to inspect deep into a battle for every bit, asked in detail about the quality and performance of equipment, he repeatedly advised the boats the men, we must learn the proper management and use of new equipment, so that new equipment combat as soon as possible.

Turn of the century, after the CPC Central Committee, Central Military Commission, China formally started the construction of new submarines.

The development of new submarines, the People’s Navy an important step in restructuring and development.

History has chosen them – the Navy Military Representative Office in a factory to assume supervision of the sacred mission of the new submarine.

New submarine must be high-tech age births. The need to re-establish production lines, processes, equipment, materials need to re-develop, staff need to re-train … … all stand in a brand new starting line.

Similarly, the military representatives stationed in a factory room will also be standing at a new starting line. From more than 10 local colleges and universities by the army and assigned to the representative chamber 40 doctoral, master’s and undergraduate students, embarked on a new type of submarine supervision positions.

The face of new submarine involved in more than 1,000 professional and technical categories, the young delegates to a military fort launched a dash of technology: “brush up” professional knowledge and 10 days won a major; familiar with drawing information, they often all night long and his eyes bloodshot; to master technical personnel and workers ask for help, plant three shifts, they Lian Zhouzhuan … … In this way, a new generation of military representatives in just 3 months into his new role on the half year to assume supervision of the independent task.

Chinese New Year has just passed, the new submarine power component installation is in progress.

Conductor gallery filled with relevant leaders and experts, through the video system, they watch every detail of installed components.

Article 10 components begin filling.

Designers, on-site construction and assembly plants have confirmed that the professional inspector: fuel assembly number, coordinates and drawing on the logo exactly the same.

As a member of the Group 3 tests, 25-year-old was alone in the military on behalf of Liu Haipeng stayed. He repeatedly warned myself: careful, careful, and then carefully!

Power Components Up to dozens of groups, internal structure, composition different from the appearance it is difficult to distinguish. Liu Haipeng Projections by the Working Principle: “10 components should not be in this position!”

On-site commander immediately ordered: operation suspended! Liu Haipeng than made after repeated: “Drawings identification error!” Authorities immediately organized the right drawing, component, loading position re-examined to confirm the conclusion that: “Liu representative was right!”

The chief architect of the new submarine the first time that this has happened, immediately called to the scene: “a young army representatives to find such an important issue, great!” Liu Haipeng awarded for this second-class power.

Submarine construction is a large and complex systems engineering. Military representative to bear from design to construction, the whole process of inspection and acceptance testing.

Fan-Ming Meng, Deputy Chief Representative briefed reporters on such a string of numbers: a new type of submarine construction from start to delivery units, the military need for the identification of projects on behalf of more than 100,000, and acceptance of technical documentation, drawings data, calculated data can be loaded with a truck .

On behalf of the whole group of seven military to check the acceptance of the project reached 1.5 million, related to the overall layout, shipping performance, hull structure, outfitting anti-corrosion, vibration and noise reduction five major professional 50 subjects; wheel unit 9 comrades in charge of 66 large systems, 732 sets of equipment; Wubei Group of electronic equipment must correspond to only a few dozen factories … …

Wu Wang Yang, 23-year-old military representative on the task of independently undertake the submarine acceptance. In September 2008, he was at the construction site supervision, “the external branch of the cartridge loop” machining, through measurements found that workers crossed position will be processing classified high. In case processing is wrong, will affect the missile launch tube of the benchmark, we should scrap the whole cartridge will bring about a series of serious consequences. The discovery of a timely, Wu ocean by the award.

Cross: In order new submarine high-performance, the face of risk is not made to give up

Represents a new type of submarine of modern science and technology and industrial development in China, the highest level achieved “From there to the superior” historic leap:

Widespread adoption of new technologies, new processes, new materials, new equipment, system is more complete, more advanced performance, operational faster reaction, and quiet performance, better and more offensive capability.

Military representatives of the leader to lead the cross.

New type of submarine tonnage big, large diameter submerged deep, deep need to adopt to withstand the pressure of new high-strength steel.

We all eyes are focused on the success of our newly developed special steel. Stretching, bending, cracking test; hardness, precision, density testing; fracture inspection, chemical analysis … …

However, it is troublesome is: precisely because of this high-strength steel “rather break than bend” and “steel” of welding very difficult.

The first welding test, examination pass rate for less than 10%!

The second, third … … have several tests, pass rate has hovered at a low level. The new submarine welding pass rate requirement to be 100%!

Problem repeatedly attack high, so that everyone felt the high-strength steel using this great risk, hastily adopted, if the weld was defective, the consequences can not imagine. “Otherwise in the end use of this steel?”

Military representatives and the builders of these concerted efforts: “high-strength steel will never give up! The key technology is not a breakthrough, submarines, it would not be ‘for type’, the follow-up boats also will be affected!”

Military Representative Office, together with the factory specialized research project and began the difficult process step by step to explore.

The whole factory selected 80 welder training, on the model tests carried out under harsh conditions. Beginning of winter frost winter, temperatures dropped to minus 20 degrees Celsius, the military brass bridge on behalf of Lee, Chen Ai-Zhi, Sun Qian, Li Ning, Zhang W, Fan name of qi, and the workers work alongside the master, facing intense welding arc welding to do test burns of the eyes, swollen cheeks frozen, and rotten cold toes, and may be their determination than high-strength steel is also hard.

Welding wire, gas, process overall innovation. From the soft and hard wire, gas ratio, welding speed to weld parts of the “warm” “After the heat,” from hand-welded to the automatic welding, work hard for 37 days, after hundreds of failures, they finally find out about the high-strength steel The “temperament,” a key breakthrough in welding technology, and achieve process stability. The range of advanced surface by means of weld testing and internal testing, with a pass rate of 100%!

The development of new submarine in the construction process, the military representatives participated in 100 research a number of major technical problems in the field of more than 10 core technologies to achieve a major breakthrough and make it applied.

This year in August, the new submarine boat on land the first joint test. Boats followed the “rotating main converter unit,” is to ensure the safety of the submarine core equipment. The FBI found that the equipment characteristics of instability, and can not be used in emergency state manual. As a test head of the military representatives Pei Feng insisted that: The new boat for the first time power system automation control, must also guarantee that an emergency start. Focus on the need for new submarines, he strongly advocated a more advanced “static-type main converter devices.”

This, at that time was a “world problem.” Representative Office in the military leadership’s support, Pei Feng took part in the research team, after hundreds of day and night research, and finally successfully developed the “static-type main converter device”, this new equipment to enable a new emergency power system, advanced submarines, reliability increased dramatically.

A truly new type of submarine is a submarine information. Electronic equipment Mimizaza, performance, complicated. Military Representative Office of the lead set up the “expert group” for the various kinds of electronic equipment on the boat to simulate the magnetic field testing, the establishment of electromagnetic radiation “ultra-poor assessment of the” new models and to analyze the surrounding equipment, anti-jamming capability. Through calculation and test, design the ideal information equipment compatible programs, the implementation of equipment, systems, the overall three control and successfully resolved the high-tech brings new risks, to ensure that a new type of submarine information superiority and comprehensive operational effectiveness of the play.

Responsibility: sign acceptance on behalf of the State, depending on the quality of the submarine, such as life -

Chief representative of the CHAI Xiao-wen, in the submarine supervision post for 20 years, participated in the development of China’s first generation of submarines supervision, supervision of new submarines is now a leading figure. He knows the military on behalf of the inspection report, signed on the weight put pen to paper: “We are representing the State Inspection and Acceptance.”

Quality is the life of the submarine, but also on behalf of the military life. The birth of each submarine, from a steel plate, a weld, a valve, a bolt, the military representatives have to personally pass three hurdles, let off a shred of vulnerability.

“Crawl space” is the military representatives of the “basic skills.” Submarines, hundreds of small compartments, each bilge corner Sazhuo their sweat.

“More difficult to drill areas, the more ‘technology accessibility’ test priorities.” Overall team leader Li Ning deliberately explained: not “drill” but “climb” and must “limbs touch the ground.” Double pressure shell caught, followed by almost a drawer, only flat tummy in, pour tummy out, get out of being stuck in the inside is a frequent occurrence. Time, the military on behalf of Zhang to 9:00 crawl out until 15 o’clock, because collapse was almost choking, dragged out, arms, knees are frayed leather … …

Ning rough forget this: 1 boat dry down, the military stands for “crawl space” total length of more than 400 kilometers, the equivalent of 10 marathons crawl forward!

“Submarine is no small matter.” The smallest details have contests. On one occasion, the shipyard, “complain”: equipment installation finished, the military on behalf of Zhang Wei does not agree and acceptance. Things, “zombies” in a plug. Zhang Wei found that, because when the cable laying into poor effort in order to insert the jack plug. He said: “so easy to break, you must re-install!”

We must find the reasons for quality problems. Army on behalf of Xu Jin-liang Regulator Fastener Torque is not found in compliance, so that equipment factory three times rework. After compliance, Xu Jin-liang not give up, persist to find out the reasons. He and plant technology, together with the nut on the bolt thread size of each measurement, one by one to do chemical composition analysis, mechanical properties of each doing testing, and finally the identification of “super bad” reasons, so that follow-up to the quality of products is guaranteed.

New submarine massive and the country’s 22 provinces, seven major industry groups, 20 design units, more than 500 factories involved in the construction. The face of enterprise restructuring, the market economy, the new environment, the military on behalf of room for adherence to “national security paramount, equipment, construction quality first”, to play a leading role in the military, brave improve coordination, promote the military, factory, the largest cooperative to ensure the construction quality.

Power plant control equipment and more interfaces there are thousands of participating in a number of design units, each interface is given not uniform, do not match. Zushi, director of the trial served as the military representatives Liu Zhizhong, repeated communication with the design department, adhere to standards, unified voltage, current interface; his trial diagram also found that some units in order to easily design and production, have larger equipment size, so that the submarine control rooms are crowded. He also and design, together with the right control system for each device one by one study, provides a unified size, and control room layout optimization. Control system for the FBI ahead of a months to complete.

Loyalty: Youth bearing glory and dreams of blood cast submarine “keel”

All tests of the submarine, we should limit the number of the most dangerous and unpredictable diving.

Chief representative of the CHAI Xiao-wen, deputy chief representative of the Fan-Ming Meng, Chen Ai-Zhi, 14 were duty-bound to participate in a new type of submarine boat limit of two types of the first deep dive test.

Army on behalf of Wang Sheng 1 week before the dive medical examination and found that the Minister of the liver the size of a 5 cm mass, initially diagnosed as hemangioma. His hesitation to make a choice: “first dive, after surgery!”

Submarine dive review, every cabin, every piece of equipment, every cable, every weld, their inspection, testing is more than six times!

Compressive deformation in the boat dive experience. The main circulating sea water system pipe, “bellows” As soon as the bursting of the influx of sea water per second would have a large number of tanks, causing an instant crash boat tragedy. The potential pre-test and calculation, found that “bellows” linear deformation changes in depth when the dive to the limit, it may even break approaching the limit of its tolerance. “Must ensure that everything goes!” Chief representative of the Cai Xiao-Wen Ma Jun, who led the repeated calculation, verification, to take the weight of “transfer” measures, successfully resolved the security problems.

China’s new submarine deep dive test a complete success!

Slipway and sweat, blood and cast the “blue whale.”

Fan-Ming Meng, deputy chief representative at the test site is to stay for 13 months; the military on behalf of Wang Sheng continuous 22-month experiment in the field to participate in sailing, sea more than 130 days out of full-qin, a voyage does not fall … …

“Saturday undertake not to rest on Sundays does not guarantee that” This is a portrayal of the military on behalf of overtime over many years.

From the start of the day the new submarine, the military representatives of the average overtime hours is equivalent to three years of the normal workload.

Before the Spring Festival in 2004, the first boat main pump motor failure. Military Representative Office bulletin board that appears in five Chinese characters “that it had no New Year”! Lunar New Year’s Eve afternoon and started this morning, TANG Yao-Yang, Xiao-Ming Xu boarded the train rushed to the manufacturer, on-site dismantling the main pump motor, analyze the causes, from the first form stem to the sixth days, until the troubleshooting.

Every 10 years, the Spring Festival, the military on behalf of a holiday is only 2 days.

Hai-wide 6-month pregnant wife, check out the suffering from pregnancy-induced hypertension syndrome. Mission at sea Zhang W, until the day before his wife give birth come back.
