The price difference is ten times, how big is the performance difference? Compared with the two latest attacks in China and the United States

Foreword: /strong>The first two-aggressive attack ship independently developed by China, Hainan, has been delivered to the Navy fleet yesterday and has been launched for only one and a half years. China is the only country outside the United States that can build large-scale two-aggressive attack ships, with only one and a half times of its reach. The two attacks of the \”Huang Hornet\” and \”American\” grades in the United States were attacked. Coincidentally, on July 15, 2020, the second ship of the \”American\” grades of the \”American\” grades of the \”American\” grades of the \”American\” grades of the \”American\” grades of the \”American\” grades of the \”American\” grades of the \”American\” grades\” was in Mississippi. Pascagoura\’s Huntington Ingles shipbuilding factory was put into service, with the platoon number LHA-7. How many similarities are there between these two attack ships?

1: The role of type 075 two-aggressive attack ship and \”US\” level two-aggressive attack ship</ After the construction of the 071 large-scale integrated landing ship, the Chinese Navy believed that the 071 large-scale integrated landing ship was equipped with 4 transport helicopters and 4 air slabs, which can be delivered at one time. 12-carat armored vehicles or a naval force combined operation, the biggest shortcoming of 071 is the air force, which cannot achieve three-dimensional and vertical landing. Without the cover of the armed helicopter, China still needs to be able to carry a large number of helicopters to carry landing operations, or to carry a vertical take-off and landing fixed wing fighter, and anti-poverty helicopter to carry a sea-making battle.

The Chinese Navy was the first to consider building domestic light aircraft carriers. Most naval personnel tend to design multi-purpose platforms like two-aggressive attacks, which can be used in landing wars or as small aircraft carriers. Helicopter aircraft carrier, so the purpose of the Chinese Navy to build 075 is very clear:There are more than 30 helicopters of various types, of which 6-10 fighter helicopters may be able to provide air fire support when landing. Secondly, the number of air-barrel ships may reach 8-12. Various types of cars have exceeded 100 trucks, and can even transport heavy 99 series main war tanks, delivering 2 synthetic operations at a time, with about 1,400 soldiers and equipment.

Type 075 Two-Attack Fleet No. 1 has been designed for three months, with 6 months of technical evaluation, 8 months of design, and 7 months of construction preparation, in 2019 \”Showing\” on the Hutung Zhonghua Shipbuilding Factory, staying on the ship for about half a year, and launching in September. The second ship was also launched in April 2020, with 12 months spent on construction, 5 months for filling, 2 months for sea trials, and 1 month for ship delivery. The average construction time is only about two years. , the construction is very smooth, indicating that China has fully mastered the complex technology of large straight-through deck type boats,

Type 075 two-attack belt length 237 meters , with a load displacement of 40,000 tons, 6 helicopter take-off and landing points, the flight deck is 230 meters long and 39 meters wide, and can be equipped with 50 main tanks or more than 250 wheels and 10 helicopters. It can be used in helicopter mothership mode Carrying 28 helicopters, the displacement and size are slightly smaller than the two attacks of the current \”Huang Bee\” and \”US\” level in the United States. Overall, the landing firepower and size of 075 are weaker than those of the \”US\” level in the United States. The latter standard It is equipped with 6 F35Bs, and is also equipped with a large V-22 transport. Modular installation methods also include loading 22 V-22s at a time or 20 F35Bs at a time, but the \”US\” level cancelled the box to enhance aviation operation capabilities. The two-in-one attack ships of the Type 075 have box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box-mounted box The width will reach 20 meters and the height will be 9.8 meters. It can be used as the mother ship for two car and air ferry boarding boats.

\”Tripo\” Two numbersThe attack ship was started in January 2014, and it took three and a half years to build and launch, and the price was about US$3 billion (it is estimated to be 6-10 times more expensive than the two attack ships of Type 075, and the export price of 20,000 tonnes of 071 is only US$170 million) The design of the \”American\”-level two attacks without a box is the same as the \”Sulphur Island\”-level two attacks without a box in the 1960s. The \”Sulphur Island\”-level two attacks with a load displacement of 18,798 tons have no box. , relying entirely on loading 28 to 32 transport helicopters to launch ultra-range attacks to avoid the enemy-level defense beaches.

However, the US Navy quickly discovered the helicopter Limited carrying capacity has led to weak firepower of landing troops, which is difficult to resist the counterattack of the enemy heavy-duty forces. Therefore, the second-generation two-aggressive attacks of the US Navy, the \”Tarawa\”-level two-aggressive attacks, introduced a cushion design, which can be used to load and load by general landing boats. The installation implements traditional beach operations and can also enter the helicopter three-dimensional landing, but the dustbin not only occupies a large amount of space and cannot expose aviation capabilities. The displacement of the two attacking ships of the \”Tarawa\” level has also increased to 39,967 tons, the third generation of the US military The displacement of the two attack ships at the \”Huang Bee\” level is not much. The main improvement is to optimize and adjust the structure and overall layout of the ship for the AV-8B attack machine and the LCAC air crater. Although the size of the caster is obviously reduced, The capacity of the landing boat increased by 3 times,

The first two attack ships of the \”US\” level have been cancelled and cannot be used The LCAC air crater boards the craft and loses the ability to deliver the main tank to reinstall the equipment like this, but greatly expands the deck area of ​​the OUT and the capacity of the Aviation Tank and the Aviation Tank, and increases the maintenance and repair facilities of the OUT and the maximum capacity of the OUT. It is equipped with 20 F-35B short-range flying/vertical landing fighters and 2 MH-60S search and rescue helicopters. Although the F-35B looks like an advanced fighter, it is not used to fight for air control, but is a replacement for the AV-8B.

AV-8B is regarded as A close-range air-support helicopter with fast flight speed, long space time and large loading capacity, the naval force has very low air performance requirements for its naval warfare, but it is completely sufficient for small and medium-sized countries that do not have a complete sea-to-air combat system. , the US naval aircraft carrier can be tightened. After seeing the China Type 075 two-aggressive attack ships, construction will start in March 2021 and are expected to be delivered in 2024.The \”American\” two-aggressive attack ship No. 3 \”Battleville\” has been restored to its cushion design, called Flight1, allowing the US military to have a larger marching space and choice area.

2: Performance of Type 075 two-aggressive attack ship and \”US\” level two-aggressive attack ship

The \”US\” level two attacks are 32.3 meters wide, designed for the 33-meter upper limit of the Panama Riverboat, while the 075 Type two attacks are 43 meters wide, inside More spacious, the forward extension curve of the 075 two-attack attack ship has a smaller diameter, and there is no external drift and long flight deck length. The \”US\”-level two-attack ships support F-35B short-range flights, and the already long ship is also outside. The drifting length of the long flight deck is larger than the \”American\” level of the two attack decks, and the folding line on the side is very low, which increases the internal capacity of the first half, while the \”American\” level of the two attack decks are straight. Although the box is cancelled, the structure has not been changed, and the resistance of the stern is greater. The stern water line of the 075 type two attacking ship is retracted into a good line type, which is conducive to increasing the speed. The bulbous bow is larger than the \”US\”-level two-step attacking steel straight tube, which is of great help to improve navigation performance.

075 The two attacks have four doors on each side, namely two folding gangways, a small car springboard and a large small boat door. The personnel climbing the gangway upwards and folds into the body of the gangway. The outside of the gangway is covered with a plate to improve the obscurity. The two attacking gangways in the United States have a pair of climbing gangways and – a car springboard. The gangway is directly hanging out of the gangway. The springboard size is also a circle smaller than that of the 075, and the width of the car is limited. 075 installed a fixed suspension car in front of the island for use between the lower deck and the flying deck., a flight deck and a large landing boat to transport large items or vehicles. , the size of the two-strength attacking trucks in the United States is much smaller, the 075\’s loading and unloading speed is much higher, and the rapid reaction can be stronger.

The two attackers of the \”US\” grade can carry 12 MV-22 tilted rotor aircraft, 6 F-35B fighters, 4 CH-53K heavy transport helicopters, 2 search and rescue helicopters, and 7 AHs -1Z armed helicopter, 075 is now loading two attack ships -8 helicopters. This model is a multi-purpose helicopter with excellent performance. It not only carries out the counter-poverty, rescue, and relay missions, but also can carry 27 full armed units. The soldiers fly 700 km or 3,000 kg of goods fly 500 km, which is very suitable for two-way landing operations. The \”US\”-level two-way attack ships can carry 12 MV-22 oblique rotor aircraft, 6 F-35B fighters, and 4 CH -53K heavy transport helicopter, 2 search and rescue helicopters, 7 AH-1Z armed helicopters, aviation combat capability is far higher than 075 two attack ships

The two attacks of the Type 075 type two attacks use the same four-stage 16PC2-6B diesel engine as the 901 large supplementary truck, with a total power of 65,000 horsepower, and a maximum speed of 901 large supplementary truck with a load displacement of 48,000 tons. The 25th session, the maximum speed of the two attacks of the Type 075 type can reach 25th session. The two attacks of the Type 075 level are 2-stage LM2500+ gas turbines, 6-stage diesel engines and 2-stage electric motors, diesel fuel combined push-in device, with a total power of 70,000 horsepower. Mali, the daily fuel consumption is only about 38% of the \”Huang Bee\” level of two attacks using steam turbines, and can generate more fuel tanks for aviation. However, since the total power has not been significantly improved, it is full. Displacement increased by 5222 tons, so the \”US\” level two attacksThe maximum speed is 20 sessions, the United States is east to the Atlantic Ocean and west to the Pacific Ocean, and the naval forces are divided into two parts, east and west. The low speed is not conducive to its rapid growth towards the hot spots in the world

The two attacking bridges of the \”US\” level are placed as much as possible at 3/5 of the entire ship, and park more aircraft out of the deck, and the two attacking ships are both included. In aviation, the bridge is in the middle, and the upper and lower aerial control rooms are fully protruding outside the island, in a slim triangle shape, and their vision is much better than the hexagonal tower platform of the \”American\” level attack. The 075 two-attack Thunder Electronic Equipment configuration is quite luxurious, the front mainmast and the 054A protective gear are quite close. The 382-adjustment Thunder, the 726 series electronic warfare system, and the sea search Thunder are all configured on the Shandong aircraft carrier. The double-sided multi-function active phased lightning device on the thunder and lightning device has low-altitude blindness and quick response capabilities, while the \”US\”-level two-aggressive attacking lightning device system includes AN/SPS–48E three-coordinate air search lightning device, AN/SPS- 49 Far, Cheng Air Warning Radar, AN/SPS-67 Sea Search Radar, Burke Three AN/SPY-6(V)AMDR Low-end AN/SPY–6(V)2EASR Multifunctional Active Phase The No. 3 fleet that is expected to be delivered in 2024 can only be used

/p>

Two attacks of Type 075 and \”USA\” The two attacking weapons of the \”level two attacking ships are similar. The two attacking ships of the United States are equipped with two 20mm 6-barrel MK-15Block1B \”intensive\” close-defense guns, and the two attacking ships of the Type 075 also are equipped with two sets of H/PJ- Type 11 30mm 11.3 million \”Wanbo\” short-range air defense system, two attacking ships of the \”US\” level are equipped with two seats 21-mounted MK-49 RIM-116 \”Ram\” short-range air-conducting transmitters, Type 075 Two attacking ships are also equipped with 2 sets of domestic red flags–10The short-range air defense guide system, the software equipment of this factory is the same as the 052-level driving velocity. It is a new-generation short-range metal foil strip device in China, which can drive enemy forces in the sea 2,000 meters away and deviate them from the bullet.

The two attacking ships of the \”US\” level also have 2 MK-29 RIM–162\” advanced model The Sea Sparrow\” ships an air-guided bullet launch device. The \”Advanced Sea Sparrow\” is the latest improved model of the Sea Sparrow\’s guide. Its effective range reaches the standard of the medium-range gear for air-guided bullets. It uses a large number of modern guided bullet control technologies, customary guidance and The mid-section is guided, X-band and S-band data chain, and the end is driven by active lightning. The air defense capability is a little stronger than the two-aggressive attack ships of the 075 model. However, the red flag installed on the two-aggressive attack ships of the 075 model – the 16 short-range air defense guide system is not difficult, it is The near-defense system of the Type 075 two-attack warfare is very clever. The near-defense system in front of the bridge can cover the forward range of about 260 degrees. The shooting range of the near-defense system at both sides of the left and right ends exceeds 240 degrees. The area where each other is overlapped is large, with 4 basic seats. The coverage rate of the six aircraft carriers was achieved, and the self-imposed weapons of the two attacking ships in the United States were reduced to the body, and the forward 90 degrees was a shooting dead corner.

Three: Conclusion

Total two attacks of Type 075 are compared with the \”US \”The two attacks of the two levels are 4,000 tons, but the installation capabilities, electronic equipment, and self-operated weapons are all in the same place. The key is that one is worth 3 billion yuan and one is worth 300 million yuan. The US navy\’s annual purchase fee is not worth 8 \”US\” ships. Two-level attack ships, the United States builds a \”US\” level two-level attack ship. China can build 10 Type 075 two-level attack ships, and the delivery time is faster than that of the United States. If the United States competes with China for the warship, it will be absolutely perfect. It\’s desirable, and larger 076The two attacks are under development. The two attacks will use 21MW grade combustion engines and 6MW grade diesel engines, medium pressure DC integrated power system, electromagnetic emitters, and electromagnetic The barrier device and 30 tons of in-board lifts will exceed the \”US\” level of two attacks. I believe that the Chinese naval forces will never build a large deck two attacks for the helicopter. China\’s short-range flying/vertical landing machine may already be in During the development, in the future, we can load the hiding battleship and attacking unmanned aircraft, and carry out two-stop delivery and possess the comprehensive air defense capabilities and strike capabilities provided by two-stop attacks at the \”US\” level. It undoubtedly marks that China\’s two-stop attacks will fully suppress the two-stop attacks in the United States. ,

Today, China has 3 Type 075 two-aggressive attack ships and 9 Type 071 large ships landed on the southeast coast The Chinese Navy will also have the ability to send joint forces to carry out combat missions in the direction, southwest direction, and important areas of the Isle of the Island Link. If three additional two attack ships of Type 076 will be added, the Chinese Navy will also have the ability to go to Africa, Central Asia, Central East, The ability to deliver armed forces in Latin America and other regions is also fully equipped with the overseas combat capabilities of the US Navy and China Navy.

When necessary, it can quickly obtain and effectively Maintain local control of important global sea routes and waterways, provide harmless navigation protection capabilities for remote transport navigation, and protect China\’s energy supply regions and overseas coastal bases outside of Central East and Africa, in accordance with the first generation of China\’s equipment, Develop a generation of traditions, and the service of a type one device means that the development of the next generation of devices has begun. The 055 driver-by-wheel drive project is exactly the time when the 052C driver-by-wheel drive project is just in service, and the 20-20 machine project is also launched. – The 10th fighter starts to serve, according to this rule, the two attacks of Type 076 are not far away.
