The navy itself is an offensive branch. Most of the navy's warships are offensive. Even if they do defensive tasks, they are a combination of offense and defense. China has spent a lot of energy to build a world-class navy, but this navy is far from reaching its peak.

In Yang Yuanzhao's view, at least, it must be like the later United States, with a large number of fleets, 30-50 aircraft carriers, thousands of ships of various types, and a large number of military ports and supply stations throughout the world, which can support the entire fleet to fight overseas for a long time.

This requires stronger maritime power. Naval ships are just a foundation. With China's production capacity today, it will take three to five years to produce so many things, and even mobilize all its strength, which will be faster.

China has always been waiting for people, not people waiting for ships. The key to the growth of China's navy is not the number of ships, but the people who operate ships. From the very beginning, China has focused on solving this problem. On the one hand, it has increased its cultivation efforts and allowed more people to enter naval schools and board ships. These people are constantly building various naval schools, and even experienced a teacher crisis. Fortunately, with the help of the captive Americans and the surrender of Japan, the school's expansion speed is acceptable. It can cultivate about 300,000 to 500,000 naval forces every year, barely enough to achieve the need for the growth of China's naval forces.

Expanding naval power, on the one hand, strengthening the navy itself and increasing the number of naval personnel, on the other hand, is to supplement the foundation of the navy. The fishing industry established in order to expand the navy, gradually began to decrease in offshore fishing because it was necessary to maintain sustainable development. It is impossible to go to sea with thousands of sails and ships, and if fishing like this, maybe there will be no fish in the entire China offshore. It is easy to destroy and build construction. China does not want to take the future path. After the most difficult time of the navy has passed, it will begin to shrink the offshore and strengthen the ocean. This part can be arranged very little. On the contrary, another slap part, the merchant fleet, because of China's continuous expansion and strengthening, continue to expand. Whether it is to meet the needs of sea transportation, or to meet the transportation of materials in the Pacific and Germany, China is constantly expanding the tonnage of merchant ships.

Merchant ships were originally for commercial shipping, but there were some changes in China. Basically, for occupation and military services, only a very small part of the commercial services. After occupying Australia and the entire Pacific islands, China comprehensively developed the islands of Australia and the Pacific Ocean, and the various materials needed for the various materials were astronomical. Therefore, China's merchant ship tonnage is constantly expanding, and a large number of tonnages have joined the ranks of merchant ships every year. China's merchant ship fleet has long surpassed Britain and the United States, becoming the world's number one, and it is another. The tonnage of other countries in the world is not as good as China's tonnage.

Spread across China's entire coastline, some of the Thai bends and Southeast Asia, these are good places to establish shipyards. China has always liked to scale. When it was built, it involuntarily referred to Shanghai and Qingdao. In addition to the two tens of million-ton shipyards and Shanghai, there are as many as 12 merchant shipyards with a scale of 3 million tons in China. If this standard is expanded to 1 million tons, there are as many as 50. If these shipyards are fully opened, they will produce up to 1 million tons of ships each year. At present, China has maintained a production capacity of 70 million tons. It is not enough to operate at full capacity, but it has almost reached its peak. After several years of construction and maintenance, the current tonnage of merchant ships exceeds 200 million.

What does this mean? A 10,000-2,000 fully armed soldiers can easily transport 1,500-2,000 soldiers to the other end of the sea. If they are as cruel as Japan, they can even reach 4,000 people. This means that China has more than tens of millions of maritime delivery capabilities. If it really wants to fight the United States, the Pacific Ocean will not be a barrier for the United States.

The construction scale of merchant ships is getting bigger and bigger, and the tonnage of a single merchant ship has increased from about 15,000 tons to 20,000 tons, 30,000 tons, or even 50,000 tons. The increasingly large merchant ships also bring very significant escort pressure. At present, there is no sign of British and American fleets operating in the Pacific and Indian Ocean, and the supplies transported to Basra are not hindered. However, with the intensification of conflict between China and the United States, the United States has also clearly realized that China's strength is, in order to attack China, they will definitely not miss any opportunity to strike China.

Attack logistics is the easiest thing to win in wars. Regardless of ancient and modern times, logistics is the most important thing for the army. In feudal society, even elite soldiers in a hundred battles will disperse. In this era of hot weapons, logistics is even more important. If the gun has no bullets, it is just a fire stick. If the cannon has no shells, it is even worse than the fire stick. The heavy iron lumps are inconvenient to move and have no attack power.

The United States does not have Sun Tzu's Art of War, but modern warfare also has a certain level of tactical research. According to routines, attacks on logistics are the best methods. In this case, the attack on merchant ships and logistics will definitely be valued by the United States, so China's merchant fleet will be in danger.

China's fleet is getting bigger and bigger, and the tonnage is getting higher and higher. Large tonnage brings convenience of shipping. The transportation cost has begun to decrease significantly with the increase in tonnage, but it also brings difficulty in escorting. A torpedo kills a 10,000-ton merchant ship, which is not much different from a 50,000-ton merchant ship. Although the tonnage of a merchant ship has increased by 5 times, it is different from a warship. It is not a crazy increase in combat power. Their combat power is similar. Basically, they can be killed by a torpedo. However, the loss is not to mention the cost of 10,000 tons and 50,000 tons. Even on cargo, there are huge losses.

With China's control over the Pacific and Indian Oceans, large-scale fleets are unlikely. With the detection range of reconnaissance aircraft and the effect of future radars, surface fleets are unlikely to enter this area. Even if they come, they can still use land-based forces to attack, the key is submarines.

Anti-submarine is a very critical matter for any merchant fleet. Although German submarines were the best in the world during World War I, it was precisely because of the role of German submarines that Britain and the United States were also studying submarines. In the early stages of submarine development, the technical level of submarines was not high. Even if the United States could not produce a submarine as powerful as China, for merchant ships, ordinary submarines were enough.

Any submarine that can penetrate the water will pose a huge threat to the merchant ship. China pushes Germany to develop its submarine tactics to the extreme. At its most powerful time, one-tenth of the merchant ships traveling to and from the Atlantic routes will sink every time they go to sea. The strike is quite powerful. If the United States uses this trick on China, the seemingly stable waterways and islands will fall into some isolated situation.

Anti-submarine is always the most important aspect of merchant ship escort. Yang Yuanzhao is also very clear about this. With the increase in land controlled by China and the continuous spread of merchant ship channel, China's anti-submarine path 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 weapon, aircraft are.

In later generations, anti-submarine was replaced by aircraft. An hourly 300 kilometers or even 500 kilometers of aircraft, compared with destroyers about 50 kilometers, the efficiency of aircraft has increased significantly. The most important thing is that destroyers cannot operate at a speed of more than 30 knots for a long time. Most of the time, they use a cruise speed of about 15 knots. However, aircraft, generally speaking, a faster aircraft, 500 kilometers is the cruise speed.

However, anti-submarine aircraft is also a new topic for aircraft. It is not as terrible as radars installing aircraft. After all, sonar is still a small thing compared to radar. At the limit, even small tonnage boats like torpedo boats can be easily installed. This is still sonar from the United States and the United Kingdom. With the progress of semiconductor technology and in-depth research on sonar, China has reduced the volume and weight of sonar to a certain extent. Of course, the smallest ******* is still unable to install sonar. If anti-submarine weapons such as deep water bombs are added, it not only requires the aircraft to tonnage to a certain extent, but also requires the improvement of sonar performance.

The former is to improve functionality, and the sonar is only a few hundred kilograms, which is not the point. The most important thing is that in addition to discovering submarines, anti-submarine aircraft also need to have certain attack capabilities. They are specially produced for submarines, and they also have the projection ability of deep-water bombs. They can deal with submarines with a minimum of more than 50 kilograms, which is usually around 100 kilograms. 100 is 10 tons, and there is no point tonnage. Even if a submarine is discovered, there is no way to deal with it.

Sonar was first brought out by China. Although the United States announced that practical sonar was the first to come out in the world, China had already obtained available sonars before the United States took them out, but it was not announced to the world for various reasons. With the deepening of materials science and understanding of sonars, China's sonars began to gradually shrink, from electron tubes to transistors, and then to integrated circuits. Along the way, the in-depth research on radio technology has gradually stabilized with increasing integration.
