According to the latest outflow of 054b**, many previous mysteries have been solved, and the vertical hair system that the enthusiastic people are most concerned about has also been revealed - continue to use the small pit of 054a.
A common flame exhaust channel between two rows of covers.
This naturally caused a lot of dissatisfaction, but looking at the world, 054B is already a high-end model in the frigate, and its comprehensive performance is currently the most comprehensive and least short board among all the new guards in the world, and even has a good cost performance, and has the potential to replace 054A in an all-round way.
system
The H AJK16 vertical hair system is equipped with the 054A series and is compatible with the HHQ-16 series anti-aircraft missiles and the YU-8 series anti-submarine missiles, and it is not ruled out that improvements will be made on the 054B to adapt to more types of ammunition. The latest model of the HHQ16 has a range of 160 km, which has surpassed the early standard type and the HHQ9 missile, is equipped with an active and passive composite guidance head, has the combat capability of air defense and anti-missile integration, and cooperates with the new double-sided shield, the actual 054B has a strong anti-air interception capability, which is no longer the same as that of the 054A. In the future, new bombs may also come out, further enhancing the firepower density and defense level of 054B.
In the middle of the hull, according to the comparison between ** and people, the bulwark is about 3 meters high, and the shading is better, but it is close to the power system intake window, and the excessively high bulwark is not conducive to the dissipation of the missile tail flame. Further observation found that each side of the bulwark has a large movable segment, and the positions on both sides are staggered front and back, which basically hammers the middle of the hull will use an inclined launch device, and the movable segment is used to lower the missile at an angle to facilitate the discharge of tail flames. This separate moving segment is not available on the 054a, as the bulwarks of the Type 54a are much shorter, which also reflects the 54b's pursuit of stealth.
054a: The bulwark here is less than one person high.
Even if you want to save some money with YJ83, the range of its latest foreign trade model has reached 290km, which is no longer the original YJ83. Some of the high configuration can be used YJ12, which has been widely used in the improvement of the "full steamed seven sons". Don't be fooled by its oblique appearance, this is a heavy supersonic projectile, and the martial arts are still abundant.
Foreign trade version, **290km range.

Anti-submarine systems. The main equipment is the bulbous bow sonar at the front and the towed sonar system at the tail, which are complementary to each other. In terms of performance alone, towed sonar is better, the detection range is large, and the impact of its own noise is minimized away from the ship, but the use conditions have certain restrictions, and it needs to be at low speed to obtain good results, and the ship's speed exceeds 10 knots to rely on bulbous bow sonar, so the highest frequency of daily use is bulbous bow sonar, unless special anti-submarine operations will be deliberately reduced to use towed sonar.
The bulbous bow sonar is naturally the larger the size, the stronger the performance, 054b has not seen its bulbous bow **, the specific shape and size are not known, roughly refer to 052d, but far below the level of 055. It should be said or not, although the 054B is positioned as anti-submarine-based, the current strongest anti-submarine capability of the People's Navy is the 055, with a larger bulbous bow sonar, the same towed sonar, and a double hangar. It's just that 055 has more important work, and you can't do everything.
Huge bulbous bow.
As for the SJG-311 low-frequency active-passive deepened towed line array sonar at the stern, it is amazing. The large hatch at the stern indicates that the 054B is equipped with towed sonar, while the SJG-311 sonar is a world-class sonar with a line array of more than 200 meters, a towing cable of up to 2,000 meters, and a detection range of 150 kilometers. Midea's AN SKR-20 low-frequency active and passive composite towed sonar of the same type has not yet been put into practical use, and in our army, it is almost a set of people up to 056A and up to 055, and 054B is naturally indispensable.
As for the noise problem of diesel engine, there is actually a certain misunderstanding. The vibration isolation level of the power system and the ability of the propeller to suppress cavitation all affect the noise level of the whole ship, which is a systematic project, not only looking at the engine, for example, the NVH level of cheap new energy vehicles will not be better than that of high-end gasoline vehicles. And when it comes to vibration isolation, we also have a national treasure-level figure - Academician He Lin, the following is quoted from the encyclopedia, everything is self-explanatory.
"Breaking through the internationally recognized technical problem of low-frequency vibration isolation of propulsion power units, we have developed a first-class vibration isolation device technology with the functions of neutral attitude monitoring, control and protection management for the first time in the world - low-frequency vibration isolation device for ship propulsion power system, realizing a major leap in vibration isolation device technology. ”
"The application and transformation research of the fifth-generation vibration isolation device technology - "magnetic levitation active and passive hybrid vibration isolation technology" (exploration of a generation of major projects) is being carried out, which can realize the synchronous control of the broadband and line spectrum vibration of the power machinery in the narrow space of the submarine, and eliminate the acoustic fingerprint characteristics of the submarine. ”
Dynamical system. From the outer ** chimney and the surrounding air intake window is not said to be exactly the same as 054a, but there are nine points similar, combined with the people's sea ** boat model division standard, the same kind of power system uses the same number, such as 051 series are steam engines, 052 series are gas engines, then 054b what host is used does not need to be repeated. As for whether it will be powered by propulsion, combined with the principle of sufficient in the previous analysis and its own positioning, it is basically impossible, but it is certain that the displacement and hull are significantly increased compared with 054A, and the 16PA6 V-280 STC diesel engine will not be used.
The following is an original report from the News Center of China Shipbuilding Industry Association in 2016:
On May 12, the high-power medium-speed diesel engine 12MV390 independently developed and manufactured by Hudong Heavy Machinery and China Shipbuilding Power Research Institute successfully passed the type approval test of China Classification Society (CCS) at the Lingang Pilot Base of China Shipbuilding Power Research Institute.
As a domestic independent brand high-power medium-speed diesel engine, 12MV390 single-cylinder power of 850 kilowatts, series of power range from 10200 to 17000 kilowatts, using high-pressure common rail, electronically controlled injection technology, fuel consumption rate: 175 grams per kilowatt hour, to meet the TierII emission standards, the performance indicators are at the international advanced level. ”
The first prototype of the 12MV390 diesel engine was successfully tested in August 2017, and the equipment 054B is just right according to the time. The power converted to horsepower is about 137~2.280,000 horsepower, equipped with 2 units to exceed the 054A's 2With 80,000 horsepower, 3 units can reach the level of 2 dog heads in 052D, which basically solves the speed problem of 054A. It's just speculation until the specific official information is announced, but at least it shows that we have a better choice of power, and the power problem is not a problem.
Since the temporary launch of the lead ship, 054B has been written one after another according to new information that is constantly appearing.
Three or four articles, there are additions to new content and corrections to the previous analysis, so far the topic of 054B's performance and positioning is basically over, and finally a brief analysis of the level of 054B in the world's frigates and whether it will replace 054A.
Through the analysis of the above and previous articles, the framework of 054B in the People's Navy has been very clear, the overall performance follows the principle of sufficient, and the use of shelf products and mature technology to reduce the cost as much as possible, which is also the main reason why it has been complained about not being "advanced and powerful", but the seemingly mediocre 054B is already a proper high-end equipment in the world's new protection, and even compared to the 45 type, the Horizon and other destroyers also have the ability to wrestle their wrists, and they can get more than 80 points in either aspect, I can reach 90 points partly.
Compared with the constellation level, first of all, it has obtained obvious advantages in cost and construction speed, the radar system double-sided rotating array loses three-sided fixed array, the types of anti-aircraft missiles are not as rich as the constellation level, and the acceleration ability of the diesel engine in terms of power is not as good as that of the constellation-level gas turbine, but the endurance is superior. The sonar system (the constellation-level active and passive composite deepening towed array module was cut when the project was established), anti-ship bombs, integrated radio frequency, and close defense systems are superior, and the two have their own strengths and basically belong to the same level.
Compared with Aquitaine, the double-sided rotating active array is better than the single-sided passive array, the anti-aircraft missile HHQ beats the aster and there is no suspense, the anti-ship and close defense system wins again, the sonar system is stronger than the Aquitaine air defense type, and the anti-submarine type is comparable, Aquitaine wins in being able to carry ground-to-ground cruise missiles, and the rest of the aspects are basically the same, and the overall small victory over Aquitaine.
At the top level, the ship's enterprising spirit is much stronger than that of the old Europe, and it is also the master who does not look up and does not look down, which is worthy of our careful study, but the overall orientation is still biased towards the style of the anti-submarine brigade in small days, why not do more hair first?
Type 22350, in a word, a short man pulls out a general, and only the so-called aesthetics of violence remains. As for the other European frigates with the name of frigates, they either live up to their name or are large yachts, and that's it.
Only by comparing goods can we know how good the 054B is, the most comprehensive performance, and there are no obvious shortcomings. Just askDigital array active phased array radar, integrated radio frequency system, active and passive composite low-frequency towed sonar, regional air defense and anti-missile integrated missile, except for 054B, which corvette in the world is currently worthy? That's what it isHigh-end large frigatesWhat makes opponents even more desperate is that it is backed by strong domestic industrial production capacity. Of course, all this must be based on the correct positioning of the frigate, and it is not smooth to compare the 055 as a model.
Due to the use of a large number of mature technologies, although the volume has increased, the cost is not too expensive compared to 054A. The hull structure accounts for a lower and lower proportion of the cost of the whole ship, and most of the parts come from the ship's electricity, armament and power. All the armament is made of mature shelf products, and the power is also an economical diesel machine, and only the ship electrical part is significantly improved, but no matter how high the double-sided small shield is not as high as the four-sided big shield, everything is within a reasonable and controllable range, based on its volume close to 052d and the same with a shield The cost is close to 052d. Since the launch of the first ship in August, it has only been more than 4 months since it was quickly outfitted for seaworthiness, which also shows that the ship is not difficult to build, and it is still a "cheap" ship, which paves the way for the mass production of 054B. Then the question arises, the first ship was commissioned in 08, and the latest batch of 054A, which has just entered service, needs to be replaced on a large scale?
Yes, but it is for the position of 054A Ocean, not the establishment of 054A, and 54A will not be laid off. Let's start with why 054b was built on a large scale.
As stealth threats and high-intensity electronic countermeasures will account for an increasing proportion of future competition, how to deal with stealth threats in a complex electromagnetic environment and improve survivability is a rigid need. The deeds of the "model of the times" Nanchang warship against the foreign carrier aircraft following the whole process implied an important message. The integrated RF system can make full use of each band, and quickly switch between each band, without revealing its own combat frequency band, while fighting interference, and finally achieve full follow-up, which is unimaginable on ships with traditional ship electrical architecture. And this kind of confrontation will become more and more intense as the pace of the People's Navy going out is getting faster and faster, and we need more such ships, and the output of ship firepower needs to be based on the advantages of electromagnetic power and information power, and this reference should not be overly superstitious about the ability of 055 single ships. 
Because the 054A is equipped with advanced towed sonar and acceptable armament, it can lead a group of 056A to carry out anti-submarine operations against China's coastal waters within the cover of the shore-based system. The submersible search is completely different from the anti-air search, due to the difference and disorder of seawater temperature, density, flow velocity, etc., the propagation and convergence of sound in seawater are nonlinear and chaotic. Sometimes the submarine is very close but you can't hear him, sometimes you hear him here but maybe he is there, searching for a dive is like opening a blind box, you can only plow it over and over again. The submarine technology of major opponents such as the United States and Japan is among the best, so the anti-submarine ships that can continue to exist with a large number of tubes are just in demand, and the 054A, which has advanced sonar and strong firepower, will not be wasted in this way. In addition, low-intensity ocean-going missions such as escort in the Gulf of Aden and overseas evacuation are also very suitable for 054A. Free 054B from these tiring tasks, so that it can concentrate on following the ocean-going formation to complete the tasks that the great powers need to complete.
The first two ships of 054B were built in two shipyards, which actually indicates that 054B will be built on a large scale in the future, otherwise there is no need to let multiple shipyards master the construction process at the same time when the first batch of ships is relatively unfamiliar, the purpose is to prepare for large-scale production.
So whether 054B will eventually reach the scale of 054A depends on the development of the external situation in the future, but in any case, the total tonnage of the People's Navy has not crossed the threshold of 3 million tons, and it is even more insufficient per capita. Building a ship like 054B is a hundred times stronger than planning to rely on unmanned boats on the other side of the ocean to maintain the size of the fleet.
