As we all know, after China experienced a round of large-scale warship "dumplings", the subsequent construction has not been interrupted, but has ensured a high and smooth construction level. If we look back eight years from now, a total of 33 shield ships of various types have been built, including 052D/DL destroyers and 055 large destroyers. This level of construction not only reflects the strength of the basic shipbuilding industry, but also demonstrates the strong production capacity of supporting technologies and equipment. Going up a level further means that the supply of advanced materials is guaranteed. For example, 33 shield ships require 132 phased arrays, and this kind of The powerful semiconductor technology has also made the West sour and sour.
According to social media reports, of the eight 10,000-ton 055 destroyers in the country, two are already combat-effective, and the rest are gradually forming combat capabilities and returning to construction, while a new batch of 052DL destroyers are under construction. It can be said that domestically produced warships have normalized "making dumplings" and maintained a smooth and high level of shipbuilding. Of course, shipbuilding is not just about building an iron shell. What is important is the supporting equipment. It must not only be able to produce, but also have high production capacity and low cost to ensure this level of "dumplings", such as The phased array radar required by the shield ship requires a large amount of gallium nitride T/R.
If we look at the level of a 052D or 052DL, one needs a 4-sided phased array radar. If we look at the current 25 052D/DL destroyers (including Lishui), plus 8 055 destroyers, for a total of 33 shield ships (excluding the 6 experimental domestic shield arrays of 052C), 132 planes of phase control are needed Array radar (this does not include early ones), and each phased array radar contains a large number of sub-arrays, and there are more sub-units underneath. The phased array radar of the 055 large-scale drive has better performance, and a single phase The array shield will only require more units. So how many semiconductor T/Rs are needed?
Take the proud Aegis of the American destroyer as an example. The later version of Arleigh Burke used the more advanced SPY-1D Aegis radar. Each system contains 4 antenna shields, including 2175 sub-arrays. Each sub-array has 2 units, totaling 4350 units. The domestic 052D and 055 large drives use the more advanced "Star of the Sea" improved multi-functional active phased array radar, developed by Dianke 14, which uses a large number of new generation semiconductor materials gallium nitride. Compared with The early Aegis radar unit not only had significantly improved power, but also had better side lobe performance. The beam width and calibration capabilities were also improved.
It can be said that these 132 phased array radars are the core of 33 domestically produced shield ships. It is conservatively estimated that based on Aegis 4350 T/R units, 580,000 T/R units are needed, and how much gallium nitride material is needed for this? Woolen cloth? It is conceivable that at a time when the West is constantly "stuck" in high-tech materials, if China's new gallium nitride materials are not completely independent in research and development and production, and have reached a level that surpasses the West in technology, then it will be difficult to guarantee the continued "downgrade". Dumplings" various shield ships. Therefore, friends who are military fans have seen that the booming shipbuilding boom is not as simple as multiple shipyards starting work at the same time. In this process, it is necessary to control the independent manufacturing of key materials and ensure production capacity. To put it bluntly, the battle is still the level of high-tech manufacturing. Rather than just shipbuilding industry.
It’s no wonder that the West, faced with China’s powerful gallium nitride material technology, can only take advantage of it again and again. After all, among the current global shield ships, except for a few Western countries that have research and development, most of them have imported American Aegis, while domestically produced ships The " Chinese Shield " is naturally very eye-catching. Moreover, the production capacity of domestically produced gallium nitride is not only guaranteed, but also relies on the advantage of production capacity to bring the price to "cabbage price", which greatly reduces the manufacturing cost of shield ships. This is another aspect of Western acid. With such high quality and low price, can the West still Want to introduce gallium nitride materials in turn? This is really a dilemma.
Generally speaking, getting rid of the shackles of Western advanced manufacturing is the basis for the development of domestic equipment. If it cannot be done, it will inevitably be restricted, and the so-called "dumplings" will be out of the question. And if the equipment imported from the West is not After fully understanding the localization, even if it is used and built, I am afraid that it will inevitably repeat the mistakes of the Falklands during the war. This may also be the most important value of the 33 shield ships and 132-sided phased array.
