The navy itself is an offensive branch of the army, and most of the navy's warships are offensive in their role, even if they are doing defensive tasks, they are also a combination of offense and defense, and China has spent a lot of energy to build a world-class navy, but this navy is far from reaching the extreme.

In Yang Yuanzhao's view, at least like the United States in later generations, it should have a large fleet, 30-50 aircraft carriers, thousands of ships of various types, and a large number of military ports and supply depots in the whole world, which can support the entire fleet in long-term overseas operations.

This requires a more powerful maritime force, and naval ships are a foundation, and with China's production capacity today, it will be able to produce so many things in three or five years, and even if it mobilizes all its strength, it will be even faster.

China has always been waiting for ships, not people waiting for ships, the key to restricting the growth of China's navy, is not the number of ships, but the people who operate the ships, this point, from the very beginning, China has focused on solving, on the one hand, increase the cultivation efforts, so that more people into the naval school, on the ship, these are constantly building all kinds of naval schools, once there was even a teacher crisis, fortunately, with the help of the captured Americans and the power of the Japanese surrender, the expansion rate of this school is quite acceptable, It can cultivate about 300,000 to 500,000 naval forces every year, which is barely enough for the growth of China's naval strength.

Expanding the naval force, on the one hand, strengthening the navy itself, so that the number of the navy increases, on the other hand, is the basis for supplementing the navy, in order to expand the navy, the fishing industry established in the past, because to maintain sustainable development, gradually the offshore fishing began to decrease, it is impossible to go to sea with thousands of sails as before, and then this kind of fishing, maybe the entire Chinese coastal waters will be left without fish, easy to destroy and difficult to build, China does not want to take the road in the future, after the most difficult pass of the navy, began to shrink the coastal waters, Strengthening the ocean, this part can be arranged very little, but the other part, the merchant fleet, because of China's continuous expansion and strengthening, continuous expansion, whether it is to meet the demand for shipping, or to meet the Pacific Ocean and the transportation of materials to Germany, China is constantly expanding the tonnage of merchant ships.

Merchant shipping, originally for commercial shipping, has changed slightly in China, basically serving the occupation and military, and commercial services occupy only a very small part. After occupying Australia, as well as the islands of the entire Pacific Ocean, China fully developed Australia and the islands of the Pacific Ocean, and the various materials needed were astronomical, and therefore, China's merchant ship tonnage was constantly expanding, and a large number of tonnage joined the ranks of merchant ships every year.

All over the coastline in China, part of Thailand Bend and Southeast Asia, these are good places to establish shipyards, China has always liked scale, in the construction, involuntarily refer to Shanghai and Qingdao, in addition to Qingdao and Shanghai two 10 million tons of shipyards, China's scale of 3 million tons of merchant shipyards, there are as many as 12, the standard, expand to 1 million tons, there are as many as 50, these shipyards if the scale is fully opened, the annual production of ships up to 100 million tons, for now, China has maintained a production capacity of 70 million tons, not at full capacity, but almost at its peak, and after several years of construction and ownership, the current merchant tonnage exceeds 200 million.

What does this mean, a 10,000-ton merchant ship can easily transport 1,500-2,000 heavily armed soldiers to the other end of the sea, and if it is as cruel as Japan, it can even reach 4,000 people, which means that China has more than 10 million sea delivery capabilities, and if it really wants to fight with the United States, the Pacific Ocean is not enough to be a barrier for the United States.

The construction of merchant ships is getting bigger and bigger, The tonnage of a single merchant ship has also increased from about 15,000 tons to 20,000 tons, 30,000 tons, and even 50,000 tons.

Attack logistics, is the war, the easiest to win, no matter ancient and modern, logistics is the most important part of the army, feudal society, less logistics, even a hundred battles of elite soldiers will be scattered, to this era of thermal weapons, logistics is more important, if the gun does not have bullets, it is a burning stick, artillery if there is no shells, even the burning stick is not as good, heavy iron lumps, inconvenient to move, and there is no attack power.

The United States does not have Sun Tzu's Art of War, but modern warfare also studies tactics to a certain extent, and according to the routine, attack logistics is the best method, and in this case, the United States will definitely attach importance to the attack on merchant ships and logistics, and China's merchant fleet will be in danger.

China's fleet is getting bigger and bigger, the tonnage is getting higher and higher, the large tonnage brings the convenience of shipping, the transportation cost is accompanied by the rise in tonnage, and it begins to decrease significantly, but it also brings the difficulty of escorting, a torpedo kills a 10,000-ton merchant ship, and kills a 50,000-ton merchant ship, which is not much different, although the tonnage of merchant ships has increased by 5 times, it is not the same as the warship, it is not a crazy rise in combat effectiveness, their combat effectiveness is almost the same, basically a torpedo can be killed, but the loss, Not to mention that the cost of 10,000 tons is different from that of 50,000 tons, even if it is on the goods, there is a huge loss.

With China's control over the Pacific and Indian Oceans, a large-scale fleet is unlikely, and with the detection range of reconnaissance aircraft and the role of future radar, it is unlikely that the surface fleet will enter this area, and even if it does, it can attack with land-based forces, the key is submarines.

For any merchant fleet, anti-submarine is a very critical thing, although it is said that Germany's submarines in the First World War, the world's best, but it is precisely because of the role of German submarines, Britain and the United States are also studying submarines, in the initial stage of submarine development, the technical level of submarines is not high, even if the United States can not produce as powerful submarines as China, but for merchant ships, ordinary submarines are enough.

Any submarine that can dive into the water will pose a huge threat to merchant ships, China pushed Germany to develop submarine tactics to the extreme, when the most powerful, the merchant ships traveling to and from the Atlantic route, every time they go to sea, one tenth of the ships will sink so that the blow is quite strong, if the United States uses this trick on China, the seemingly stable shipping lanes and islands will fall into a certain isolated situation.

Anti-submarine is always the most important aspect of merchant escort, which Yang Yuanzhao is also very clear, with the increase of land controlled by China, coupled with the continuous spread of merchant shipping lanes, China's anti-submarine road has also begun to progress, with the experience of later generations, Yang Yuanzhao is very clear that for anti-submarine, destroyers are not the best weapons, aircraft are.

In later generations, anti-submarine is replaced by aircraft, an hour of 300 kilometers, or even 500 kilometers of aircraft, compared with about 50 kilometers of destroyers, the efficiency of aircraft has increased significantly, the most important thing is that destroyers can not be at a speed of more than 30 knots, a long time to sail, most of the time is used about 15 knots of cruising speed, but airplanes, generally speaking, faster aircraft, 500 kilometers is the cruising speed.

It's just that the anti-submarine aircraft, for the aircraft, is also a new topic, not as terrible as the radar on the plane, after all, sonar relative to the radar, is still a small thing, the limit, even the torpedo boat such a small tonnage boat can be easily installed, this is still the United States and Britain sonar, with the progress of semiconductor technology, as well as the in-depth research on sonar, China has reduced the volume and weight of sonar to a certain extent, of course, the smallest******** It is still impossible to install sonar, and if you add anti-submarine weapons such as depth charges, it not only requires the tonnage of the aircraft to reach a certain level, but also needs to improve the performance of sonar.

The former is to improve functionality, sonar is only a few hundred kilograms, this is not the point, the most important thing is that anti-submarine aircraft out of the submarine to discover the submarine, but also need to have a certain attack capability, specially for the submarine production of them, also have the ability to deliver depth charges, can deal with the depth charges of submarines, at least more than 50 kilograms, generally around 100 kilograms, 100 is 10 tons, there is no point tonnage, even if the submarine is found, there is no way to deal with it.

Sonar is the first to be taken out by China, although in the world, the United States announced that practical sonar is the first to come out, China has already got the sonar that can be used before the United States came out, but for various reasons did not announce it to the world, with the deepening of materials science and understanding of sonar, China's sonar began to shrink gradually, from electron tubes to transistors, and then to integrated circuits, along the way, the deepening of research on radio technology, accompanied by higher and higher integration, The performance has also gradually stabilized.

At present, sonar has been gradually miniaturized, can be reduced to about 250 kilograms, the minimum less than about 0.57 cubic meters, which is not an unaffordable for larger and larger aircraft, but in high-speed aircraft, to ensure the accuracy of sonar, this is more difficult.
