CCTV News:According to WeChat official account news released by Fuyang,On July 22 ndAs late as the early morning of the 23rd, short-term heavy rainfall in Fuyang District of Hangzhou triggered flash floods and caused local landslides and mudslides, involving Dayuan Town, Shangguan Township and Evergreen Town. As of 14: 00 on July 23, a total of 5 people died and 3 people lost contact (still in the process of search and rescue); There were 32 mountain torrents in small watersheds, 144 geological disasters, 26 dilapidated houses damaged or collapsed, 1,619 households affected by power outage, 42 vehicles flooded and 21 roads were interrupted.The Flood Control and Drought Relief Headquarters of Fuyang District People’s Government informed the latest situation, as follows.

　I. Heavy rainfall

　　First, short-term heavy rainfall. Since the rainfall monitoring point was set up in Fuyang District in 1955, the maximum rainfall per hour is 83.5mm.. This short-term heavy rainfall is extremely rare. From the evening of July 22 to the early morning of July 23, the rainfall in the whole region was 26.1 mm, the largest being 209 mm in Shijia Village of Dayuan Town, followed by 169 mm in Dasheng Village of Shangguan Township. Among the top ten stations with rainfall, there are 4 in Dayuan Town, 4 in Shangguan Township and 2 in Evergreen Town. Among them, the four rainfall monitoring stations in the border area of Shangguan Township, Dayuan Town and Evergreen Town exceeded the historical maximum rainfall per hour, namely 112.4 mm in Dasheng Village of Shangguan Township, 95.7 mm in Fangcun Village of Shangguan Township, 94.5 mm in Shuangxi Village of Evergreen Town and 88.8 mm in Shenli Village of Shangguan Township.

　　Second, the rainfall area is concentrated. Affected by short-term heavy rainfall, due to the narrow mountainous area at the junction of the three towns, the rainwater was collected very quickly, and the short-term rainfall was collected in the river at the first time. The instantaneous flow of Evergreen Creek, Shangguan Section of Tunxi and Luocun Qingong Section of Shijiacun Village of Dayuanxi was huge, and the main roads (including provincial and county rural roads) in Dayuan, Shangguan and Evergreen areas were flooded for 73.6 kilometers. According to the on-site witness and video playback, the river surged instantly, and the flooded level of villages and factories on both sides of the river rose by 1.5-2 meters in 10-15 minutes, accompanied by the collapse of many roads, which seriously blocked traffic and prevented vehicles and pedestrians from entering and leaving for nearly 2 hours.

　　Second, the emergency response

　　Provinces and cities attach great importance to Fuyang’s short-term emergency rescue response to local rainstorm. The main leaders of the provincial party committee and government, the municipal party committee and municipal government gave instructions at the first time, and the executive vice governor of the provincial government, the mayor of the municipal government, the executive vice mayor and relevant departments of provinces and cities went to Fuyang to guide the emergency rescue work. All the people in the whole region are United and go all out to rescue:

　　The first is to implement upgrading control. On July 22nd, Fuyang Meteorological Bureau issued yellow, orange and red rainstorm warnings at 15: 44, 17: 03 and 17: 34, respectively, and the flood control emergency response was launched in an all-round way. The main responsible persons of the district committee and government went to Shangguan and Dayuan to conduct on-site command, and the relevant responsible persons of the district defense index went to the district emergency command center to take command and coordinate various rescue work.

　　Second, the strength sinks. 609 rescue teams, including district-level comprehensive rescue, fire rescue, emergency rescue of five state-owned enterprises’ platforms, public security, transportation and medical care, with a total of 6,230 people, involved 1,536 people in dangerous areas, including 695 people in Shangguan Township, 236 people in Evergreen Town, 525 people in Dayuan Town, and 80 people in towns and villages such as Longmen and Huyuan.

　　The third is to work together to rescue. Cadres and villagers at all levels in party member fought all night to carry out personnel search and rescue, emergency repair of power communication, etc. Eleven tourists were trapped in Longmen Mountain, and all the trapped people were rescued and safely sent away at 20 pm on the 22nd. Xiner Village in Huyuan Township has a large amount of water, with 100 meters of roads washed away and 48 farmers trapped. At present, all the people have been safely relieved. Some houses and factories in Xinguan, Qikou, Luocun, Qingong, Qingshan, Sanling, Shijia and other villages in Dayuan Town were flooded, and 7 houses collapsed, and all the personnel were transferred in advance. Other towns and streets in the region are currently in a stable flood situation.

　　Third, the next step of work measures

　　First, fully organize flood fighting and disaster relief work. Concentrate on disposal, set up five working groups including personnel transfer, disposal and rescue, and clearing obstacles, and do a good job in personnel search and rescue and related disposal; The implementation should be completed, and the towns and streets should pre-judge and mobilize the personnel who should be transferred to small watersheds, geological disasters and dilapidated houses within their jurisdiction. From 7: 00 on July 23, the corresponding personnel should be reported every hour to ensure the safe transfer of personnel in dangerous areas; Strengthening emergency duty, cadres and workers in the whole region devoted themselves to flood control and disaster relief. Among them, district leaders sank into the town street according to the contract system and carried out supervision and guidance on the transfer and prevention and control.

　　The second is to fully search and rescue the lost personnel. Fuyang Branch of the Municipal Public Security Bureau took the lead, and the professional rescue teams of various departments and the comprehensive rescue forces of towns and villages went all out to do a good job in search and rescue, and implemented the control of the affected areas and surrounding areas, so as to prevent the occurrence of secondary disasters while doing a good job in personnel search and rescue.

　　The third is to fully carry out post-disaster repair and reconstruction. District Transportation Bureau, district power supply company and district mobile operation company arrange emergency rescue teams to rush to the scene 24 hours a day to do a good job in post-disaster repair and reconstruction. Among them, the District Transportation Bureau focuses on the emergency repair of damaged road sections, while speeding up the transportation and cleaning of roads, and stepping up inspections of roads, water and projects under construction to ensure the improvement of emergency response efficiency and safe and smooth transportation.

　　The fourth is to fully protect the lives of the affected people. Immediately carry out the nuclear disaster, do a good job in continuing to report the disaster, start the disaster response, organize relevant departments and local towns to carry out post-disaster self-help and reconstruction, and ensure timely and sufficient food, clothing and accommodation for the people affected by the collapse of houses. Quickly carry out epidemic prevention and disinfection to prevent the spread of infectious diseases after disasters and ensure the safety of people’s lives and property.

CCTV News:Affected by the global epidemic, from January to February, China’s import and export, export and import decreased by 9.6%, 15.9% and 2.4% respectively. At present, foreign trade enterprises generally face problems such as cancellation or postponement of orders in hand, difficulty in signing new orders, and poor logistics and transportation. Today (10th) afternoon, the joint prevention and control mechanism of the State Council held a press conference at the State Council Office. Ren Hongbin, Assistant Minister of Commerce, introduced that in order to cope with the impact of the epidemic on foreign trade, the the State Council executive meeting on April 7th put forward a series of policies and measures to stabilize foreign trade, including adding a comprehensive cross-border e-commerce test zone, supporting the development of processing trade, and holding an online Canton Fair.

Ren Hongbin, Assistant Minister of Commerce:First, add a number of cross-border e-commerce comprehensive experimental zones. Since 2015, the State Council has set up 59 cross-border e-commerce comprehensive test zones in four batches. In 2019, China’s cross-border e-commerce retail import and export volume reached 186.21 billion yuan, five times that of 2015, with an average annual growth rate of 49.5%.

At present, traditional foreign trade has been severely impacted by the epidemic, and it is necessary to further develop the unique advantages of cross-border e-commerce. On April 7th, the State Council decided to set up 46 new comprehensive test areas, and with 59 approved, there will be 105 comprehensive test areas in China, covering 30 provinces, municipalities and autonomous regions, forming a development pattern of land and sea linkage and mutual assistance between east and west. The comprehensive test area will continue to carry out pilot tests, and apply policies and measures such as cross-border e-commerce retail export tax and retail import supervision.

Second, support the development of processing trade. Reduce the domestic sales cost of enterprises. When bonded materials or finished products of processing trade enter the domestic market for sale, import link tax shall be levied according to regulations, but deferred tax interest shall be temporarily exempted until the end of the year. Expand the pilot of selective taxation in domestic sales. We will expand the pilot project of processing trade enterprises choosing to pay tariffs on imported materials or finished products for domestic sales to all comprehensive bonded areas, so as to reduce the actual tax. Optimize the structure of processing trade. Accelerate the revision of the catalogue of industries that encourage foreign investment, promote the high-quality development of manufacturing industry, and enhance the ability of the central, western and northeastern regions to undertake industrial transfer. Expand the scope of commodity access. Some products that are in line with the industrial development policy and no longer belong to "two highs and one capital" are excluded from the prohibited category of processing trade.

Third, the online Canton Fair was held for the first time. Traditionally, the annual spring Canton Fair opens on April 15th. On April 7th, the the State Council executive meeting decided that the 127th Canton Fair would be held online in the middle and late June. This online Canton Fair will mainly include three parts: online display docking platform, cross-border e-commerce zone and live marketing service, and continue to give full play to the advantages of trade fairs. Provide online promotion, supply and procurement docking, online negotiation and other services for exhibitors and buyers, so that Chinese and foreign merchants can place orders and do business without leaving home and make positive contributions to the stability of world economy and trade together.

Core reading

At present, the large-scale continuous high temperature weather in the south has basically ended. The unusually strong subtropical high in the western Pacific is the most direct cause of the high temperature weather this summer. This is related to the general trend of global warming, and also to the abnormal SST in the northwest Pacific Ocean on the seasonal scale.

At 18: 00 on August 30, the Central Meteorological Observatory lifted the yellow warning of high temperature, and the large-scale continuous high temperature weather in the south basically ended. This round of high temperature is the strongest comprehensive high temperature since there was a complete meteorological observation record in 1961, and its duration, range above 40 degrees Celsius and extremes have set a new historical record.

This year, the western Pacific subtropical high is extremely strong, which is the most direct cause of persistent high temperature weather. What is a subtropical high? Why is the subtropical high in the western Pacific unusually strong this year?

The anomaly of subtropical high is the most direct cause of persistent high temperature weather.

Recently, Sichuan Basin, Shaanxi, Chongqing and other places have continuously ushered in heavy precipitation, and the high temperature has finally subsided.

This summer’s high-temperature heat wave event started early, lasted for a long time, affected a wide range and had strong comprehensive intensity. Meteorological monitoring shows that from June 13th to August 30th, the regional high temperature event lasted for 79 days, covering more than 5 million square kilometers. There were 23 provinces with high temperatures above 40 degrees Celsius, and the daily maximum temperature of 366 national weather stations reached or exceeded the historical extreme.

Due to the long duration of high temperature, some rivers dry up during the main flood season. In the Yangtze River basin, the water levels in many places have been the lowest in the same period since the record was set, and Dongting Lake and Poyang Lake "dried up" ahead of schedule. At the same time, high temperature weather has also brought various adverse effects to people’s production and life, such as the surge in demand for electricity, the decline in hydropower production, the obstruction of agricultural production, and forest fires.

Chen Tao, the chief forecaster of the Central Meteorological Observatory, said that this year’s western Pacific subtropical high has a large range and strong intensity, which is the most direct cause of persistent high temperature weather. Under its control, the southern part of China is controlled by downward flow as a whole, with clear skies and partly cloudy. During the day, under the influence of sunshine radiation, the near-surface heating is intense, and the hot air stays on the ground, which can’t be blown away or dispersed, so there is a wide range of persistent high temperature weather.

Not only in China, but also in the northern hemisphere this summer, the western Pacific subtropical high, the Atlantic subtropical high and the Iranian high have all been strengthened in stages, forming a large-scale global warm and high-pressure belt and forming high-temperature weather in many parts of the northern hemisphere.

"The occurrence of high-temperature heat wave events in summer is normal from the perspective of climate state. However, the duration, intensity and influence range of this summer’s high-temperature heat wave event have reached a super level. " Chen Lijuan, chief forecaster of National Climate Center, analyzed that persistent atmospheric circulation anomaly is the "culprit" of persistent high temperature. This year, the western Pacific subtropical high is unusually strong and extends westward, and the west reaches the eastern part of the Qinghai-Tibet Plateau. At the same time, the southern and northern boundaries of the subtropical high are both extended, and the area is very large. In summer, the high temperature events in most parts of southern China last for a long time, and the end time is obviously later than normal.

The strong subtropical high zone blocks the transport of water vapor from the low-latitude ocean to the south.

What is the subtropical high? Why does it often appear in high temperature and summer events? Why is it so powerful this year?

Zhang Daquan, a senior engineer in the Climate Prediction Office of the National Climate Center, said that the well-known subtropical high generally refers to the subtropical high in the northwest Pacific Ocean in the northern hemisphere, which has a great impact on China. It exists all the year round and is located in the middle and lower troposphere of the atmosphere. It is a stable and warm deep system with little movement. Due to the strong solar radiation in the equatorial region, the atmosphere is heated up and flows to the north and south poles with lower temperature. Under the influence of the earth’s rotation, it settled around 30 degrees north and south latitude, and then the air flow returned to the equator, forming an atmospheric circulation circle called Hadley circulation. The subtropical high is formed when the airflow sinks in the subtropical area near 30 degrees north and south latitude.

Affected by land and sea distribution and other factors, the subtropical high belt in the northern hemisphere splits into several high-pressure units, namely, the North Pacific High, the North Atlantic High and the Iranian High. Among them, the western part of the North Pacific High-the Western Pacific Subtropical High has an important impact on China’s weather and climate, and its staged "northward jump" is directly related to the start and end time of the rainy season and the location of the rain belt in the eastern monsoon region of China, while abnormal advance and retreat and stable maintenance are important factors leading to abnormal weather and climate in China. After the "Meiyu" every year, the main body of the West Pacific subtropical high directly controls the middle and lower reaches of the Yangtze River, and the downward flow leads to sunny and hot partly cloudy, with strong solar radiation, which usually leads to high temperature and summer drought.

This year, the subtropical high is extremely strong, resulting in continuous high temperature and little rain in the Yangtze River basin, which is more and stronger than the perennial high temperature and summer drought weather. From the perspective of influencing factors, on the one hand, it is related to the overall trend of global warming, on the other hand, it is also related to the thermal anomaly of the Qinghai-Tibet Plateau, La Nina phenomenon and SST anomalies in the Indian Ocean and the Northwest Pacific Ocean on the seasonal scale.

This summer, the heating effect of the Qinghai-Tibet Plateau was remarkable. The South Asian high over the Qinghai-Tibet Plateau was unusually strong, and the West Pacific subtropical high strengthened its westward extension and opened up with the Iranian high in the west of the plateau. The strong subtropical high zone blocks the transport of water vapor from the low-latitude ocean to the southern part of China, and the area controlled by the subtropical high continues to have high temperature and little rain. Judging from the marine conditions, this summer is in La Nina state, the SST in the equatorial Middle East Pacific is abnormally low, and the SST in the western Pacific and the South China Sea is high. The tropical SST anomaly is conducive to the strong and large subtropical high in the west Pacific through the air-sea interaction, which leads to a wide range of high temperature this year, including Huanghuai, Jianghan, Sichuan and Chongqing.

Raise awareness of adapting to climate change and actively respond.

Chen Lijuan believes that the extreme characteristics of high temperature events this year are closely related to the background of climate change.

The sixth assessment report of the United Nations Intergovernmental Panel on Climate Change (IPCC) pointed out that under the background of global warming, many extreme weather and climate events have been observed since the middle of the 20th century, among which the frequent occurrence of high-temperature heat waves is a very significant feature.

"This is a warning to us, prompting us to have a deeper understanding of climate change and improve our ability to adapt to climate change in all aspects." Zhang Daquan said, "In recent years, China’s ability to cope with climate risks and reduce and prevent disasters in agricultural production, floods and architectural design has been improving. On the other hand, we should also raise the awareness of the whole society to adapt to climate change, use climate prediction products to cope with climate risks in advance, and strive to minimize social and economic impacts and losses. "

Experts explained that in the context of climate warming, this summer’s high-temperature heat wave broke the historical record and has certain extremes. However, from the perspective of climate periodicity, because the earth’s climate system has self-regulation function, the increase in the probability of extreme events does not mean that the same type of extreme events will occur every year.

On the other hand, with the development of social economy, the demand for meteorological services by the country and all walks of life is increasing, which requires meteorological departments to further improve the accuracy of forecasting, and at the same time expand the forecasting objects to the downstream, and develop climate risk forecasting based on disaster risk assessment, so as to facilitate decision-making departments and the public to deal with climate change more scientifically and effectively.

Comfort configuration is often linked to the quality of a car. Of course, the higher the comfort configuration, the more pleasant the passenger experience, which can give the car a higher evaluation. What xiaobian brought today is. Not much to say, let’s take a look.

First of all, from the appearance, the Mercedes-Benz EQE front shape has taken a cool route and looks very elegant. Coupled with avant-garde headlights, the visual effect is extremely impactful. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, automatic steering, delayed closing and so on. Coming to the side of the car body, the size of the car body is 4969 mm * 1906 mm * 1514 mm. The car uses sharp lines, and the side circumference looks very cold. With large-sized thick-walled tires, it looks full of sports. In the rear design, the rear line of Mercedes EQE is fashionable, and the taillights are full of design style, which is very simple.

Coming into the car, Mercedes-Benz EQE interior presents a hard-core design style, which is very in line with the tastes of young consumers. The car looks very good outside the steering wheel, made of leather, and has a full and delicate grip. From the central control point of view, the car is equipped with a stable and atmospheric touch OLED central control screen, which makes the interior design quite layered and the details are still in place. The dashboard and seats are also eye-catching, and the shape has taken the sports route. The car uses a leather-like seat, and the seat is wrapped in place, which is very comfortable to ride.

Mercedes-Benz EQE matched gearbox, 215KW, 556N.m, with good power performance.

Mercedes-Benz EQE is equipped with car networking, driving mode selection, remote control key, interior atmosphere light, traction control (ASR/TCS, etc.) and other configurations, which is worthy of praise.

To sum up: such a car with the right price is enough to meet the daily practical needs, and it doesn’t take much thought to maintain it at ordinary times, and the price is good.

According to media reports in Taiwan, China, the first ship of Taiwan’s "Tajiang" class missile patrol ship "Tajiang" was delivered ahead of schedule on July 27th.

Taiwan’s "Central News Agency" reported that Taiwan’s defense department said that in order to cope with the frequent cruises of PLA military aircraft, it was originally planned to complete three "Tajiang" ships in 2025. After coordinating with Longde Shipyard, it was changed to complete the operational evaluation this year and complete six ships by 2023. At present, one can be delivered soon, so the progress is ahead of schedule.

Taiwanese media said that the "Tajiang" class patrol ship is the "carrier killer" of the Taiwan military, and it is an effective asymmetric combat force for the Taiwan military to "defend and stick to it".

So, what is the combat power of the "Tajiang" class patrol ship? Is the title of "aircraft carrier killer" worthy of the name?

The first ship of "Tajiang" class missile patrol ship "Tajiang".

From "Tuojiang" to "Tajiang"

The "Tajiang" class is an upgraded version of the "Tuojiang" class ship, and the first ship of the "Tuojiang" class "Tuojiang" was delivered in December 2014. The name "Tuojiang" is to commemorate the gunboat "Tuojiang" which was destroyed and scrapped by the People’s Liberation Army in the naval battle of Liaoluowan on September 2, 1958 (Tuojiang is a tributary of the upper reaches of the Yangtze River in Sichuan).

"Tuojiang" is 60.4 meters long and has a full displacement of about 600 tons. It is a wave-piercing catamaran with stealth design, and its maximum speed can reach 38 knots. Although the "Tuojiang" has a displacement of only about 600 tons, it has piled up a large number of weapons, including a MK-75 76 mm naval gun, a MK-15 "dense array" near defense system, two MK-32 triple-mounted 324 mm torpedo launchers, four 12.7 mm machine guns, and eight anti-ship missiles of Xiongfeng 2 and Xiongfeng 3. It can be said that

However, the "Tuojiang", which has high hopes, has exposed some problems in sea trial and use, such as insufficient buoyancy, excessive vibration during navigation and greatly reduced speed. It has been rumored many times that the towed array sonar of "Tuojiang" is affected by the high vibration and noise generated by the hull during navigation. Although the Taiwan navy denied it many times, the subsequent mass-produced "Tajiang" class missile patrol ship cancelled the towed array sonar and anti-submarine torpedo launcher.

During the sea trial and use, the "Tuojiang" exposed some problems, such as insufficient buoyancy, excessive vibration during navigation, and greatly reduced speed.

As a mass production type of the "Tuojiang" class missile patrol ship, the "Tajiang" started construction at Longde Shipyard on May 24, 2019 and was launched on December 25, 2020. The word "Tower" in the name of the ship "Tajiang" is taken from Wataxi in Taitung County and matched with the word "Jiang" in the naming pattern of Taiwan patrol ships, which is another manifestation of Democratic Progressive Party authorities’ "going to China".

Compared with the "Tuojiang", the length of the "Tajiang" class is increased to 65 meters, the width is increased to 14.8 meters, the full-load displacement is increased to 685 tons, the draft is 2.1 meters, and the endurance is reduced from about 2,000 nautical miles of the "Tuojiang" to about 1,800 nautical miles. Structurally, the "Tajiang" class changed the bottom of the two pieces of the hull under the waterline of the "Tuojiang" from V-shape to U-shape, and adjusted the shape of the bridge, cab, mast, etc., and moved the position of the smoke outlet from the vicinity of the outboard waterline on both sides to two meters above the inboard waterline to enhance concealment.

In terms of weapons and equipment, there are many changes in the Tajiang class compared with the Tuojiang class: the anti-submarine torpedo launcher is cancelled, the number of Xiongfeng 2 and Xiongfeng 3 anti-ship missiles is reduced to 8 and 4 respectively, and 16 Haijian 2 medium-range ship-to-air missiles and their supporting CS/MPQ-90 X-band single-sided phased array radar are added.

In addition, Taiwan Province Coast Guard also plans to build 12 "Anping" class patrol ships based on "Tuojiang". The size of "Anping" class patrol ship is larger than that of "Tuojiang", and the full-load displacement is increased to about 700 tons. Because it is not equipped with anti-ship missiles, its speed can reach more than 44 knots. However, it should be noted that "Anping" class patrol ship has reserved missile launching cabin and interface, which can be equipped with "Xiongfeng" 2 and "Xiongfeng" 3 anti-ship missiles, "dense array" near defense system and other weapons and related systems in wartime, and the peacetime and wartime conversion can be completed within 24 hours. Two "Anping" class patrol ships have been delivered at present.

Although the displacement is only over 600 tons, the "Tajiang" class has piled up a large number of weapons, including 76 mm naval guns, anti-ship missiles, ship-to-air missiles, near-defense guns and machine guns.

Embarrassed "carrier killer"

Objectively speaking, the "Tajiang" class has indeed solved some problems existing in the "Tuojiang", but there are still many problems due to its backward design concept and insufficient capacity.

It seems unnecessary for Taiwan navy to adopt the design of wave-piercing catamaran. Although the wave-piercing catamaran has the advantages of good seaworthiness, reducing wave-making resistance and facilitating the layout of superstructure, it also has the disadvantages of heavy structural weight, which is not conducive to large-scale and high lateral stability.

First of all, the two hulls and superstructure of the wave-piercing catamaran are more complicated than the traditional monohull ship with the same tonnage, which requires more materials and has a much larger structural weight. In order to reduce weight, catamarans are mostly made of aluminum alloy, and the "Tuojiang" and "Tajiang" missile patrol ships are no exception, which will inevitably lead to rising procurement and use costs. For example, it will cost more than NT$ 5 billion (about RMB 1.156 billion) to purchase a "Tajiang" missile patrol ship.

Secondly, the connection structure between the two pieces of the wave-piercing catamaran is complicated. When the distance between the two pieces is large, the connection structure must be made of steel with good structural strength, which will inevitably increase the structural weight, reduce the effective load, reduce the economy and limit its large-scale development.

The "Tajiang" class can carry up to 16 anti-ship missiles with firepower comparable to destroyers.

Finally, the wave-piercing catamaran has a larger width and higher lateral stability, but when the sea conditions are higher, it produces a larger lateral stability moment and a higher rocking frequency, which leads to a decline in seaworthiness. At the same time, the pitching of the wave-piercing catamaran has not been alleviated. According to Taiwan media reports, when the "Tuojiang" was seaworthy, the crew vomited more seriously because of its strong pitching.

At present, what the Taiwan Navy urgently needs is to be able to replace the old Jinjiang class missile patrol ship. After the "Jinjiang" class is completely retired, the complicated patrol tasks can only be undertaken by Taiwan naval frigates, which will consume its limited service life faster. "Jinjiang" class is equipped with sonar, anti-submarine torpedo and deep-water bomb, which has basic anti-submarine capability, while "Tajiang" class has no anti-submarine capability at all.

It can be seen that the real purpose of Taiwan Province’s construction of the "Tajiang" class missile patrol ship is not to replace the "Jinjiang" class as stipulated in the plan, but to develop an anti-ship missile launching platform, strengthen the overall anti-ship capability of its navy, and enhance its so-called "rejecting reunification by force" capability. Some Taiwan Province media even refer to the "Tajiang" class as an "aircraft carrier killer", but this is just wishful thinking.

On the one hand, although the "Tajiang" class can carry up to 16 anti-ship missiles, and its firepower is comparable to that of destroyers, it also occupies the hull space and can only install simple electronic equipment, which leads to its extreme dependence on friendly and neighboring combat platforms and combat information networks, and its independent combat capability is extremely weak. In the face of systematic air and sea strikes, friendly and neighboring combat platforms and combat information networks are easily broken one by one, and its lack of independent combat capability is more like a "large missile boat". Moreover, the equipped "Xiongfeng" 3 supersonic anti-ship missile claims to have a range of 400 kilometers, but it can only be achieved when the flying height exceeds 15,000 meters, and it is easy to be intercepted. If low-altitude trajectory is adopted, the range is only about 150 kilometers.

On the other hand, the self-defense ability of "Tajiang" class is insufficient. Taiwan authorities say that these two-stage missile patrol ships have achieved stealth, but Taiwan Province has not accumulated much stealth technology, and the actual effect is in doubt. In terms of air defense, the ship is equipped with a "dense array" near-defense "Haijian" 2 ship-to-air missile. The maximum range of the missile is about 30 kilometers, and the inclined fixed launch box is adopted. This design not only limits the launch angle of the missile, but also has a small bomb load. Although the "Tajiang" class has a certain self-defense capability, if the launch platform of the other anti-ship missile launches a saturation attack 30 kilometers away, the "Tajiang" class will be overwhelmed and easily overwhelmed by the other anti-ship missile. Newer weapons such as the "Tajiang" class must be the focus of attention in wartime. Ballistic missiles and various types of anti-ship missiles are the nightmare of the "Tajiang" class, and there is almost no chance to attack the opponent’s aircraft carrier. The title of "aircraft carrier killer" is not worthy of the name.

Haijian 2 ship-to-air missile is improved from Tianjian 2 air-to-air missile.

The facade of the "national ship made in China" plan?

The "Tajiang" class is a part of the so-called "national ship-building" plan in Taiwan, China, which can be said to be ambitious. The Taiwan military and the coast guard will jointly build 238 ships of various types.

This huge shipbuilding plan, regardless of whether the funds are sufficient, is beyond the capacity of Taiwan Province’s shrinking shipbuilding industry. For example, in the famous "Qingfu Cheating Case", Qingfu Shipbuilding Co., Ltd. built a civilian ship in its early years, and won the contract for six mine-hunting ships of the Taiwan military in 2014. It plans to complete the order by the so-called "national ship made in China". Qingfu Company, while buying mine hunting equipment system from the United States, entrusted Italy to build the first ship, and was busy transferring assets and obtaining loans, and was finally discovered, which also involved people from Taiwan, government and military circles. The disadvantages of Taiwan Province shipbuilding industry can be seen from this. The Budget Center of Taiwan’s legislature thinks that such a huge shipbuilding scale is really inconsistent with Taiwan Province’s actual shipbuilding capacity.

The "Haijian" 2 ship-to-air missile adopts an inclined fixed launch box, and its firing range is limited.

In addition to the sluggish shipbuilding industry, the research and development capabilities of related supporting military industries are also declining. For example, Haijian-2 ship-to-air missile, which was developed by Chinese Academy of Sciences in 1999, claimed to have obtained two key technologies related to the vertical launch of ship-to-air missile, namely missile thrust vector system and "cold launch" technology. However, until 2007, Taiwan’s "Chinese Academy of Sciences" showed the backward inclined fixed launch box, and the vertical launch system has not been followed. Now it can only turn to the United States. In 2019, "Haijian" 2 conducted the first live-fire shooting test on land using the purchased American MK-41 vertical launching system.

If we can find ways to make up for the decline in R&D and construction capacity, then the backwardness of the concepts of Taiwan’s political and military circles, scientific research departments and shipbuilding industry is the biggest shortcoming that it cannot make up for. Let’s take the Haijian 2 missile as an example. The Taiwan military plans to install Haijian 2 on those old frigates to enhance their air defense capabilities. However, due to the hull structure, internal space and missile length, some frigates are not suitable for installing vertical launch systems, so the inclined fixed launch box can also be used as a way to enhance air defense capabilities. It is such a simple technical problem, but the Taiwan military is divided into "inclined launch box faction" and "vertical launch system faction". The two sides do not give in to each other, and even the top defense department needs to come forward to reconcile and compromise. In the 21st century, when the vertical launching system is very popular, Taiwan’s Chinese Academy of Sciences is still thinking about the inclined fixed launching box, and even developed the so-called "integrated shell oblique launching frame", that is, the inclined fixed launching box considering the stealth problem, in order not to destroy the stealth shape of the ship.

The "Tajiang" class missile patrol ship is a well-run project in the so-called "national ship made in China" plan of the Taiwan authorities, but it also exposes that Taiwan Province’s ship-building ability, technology and concept are completely backward, and it is difficult to hold up the so-called "national ship made in China" facade.
