When merchant ships just entered the ten thousand ton era in the early 20th century, China took another step, reaching 30,000 tons, which means that China has a very high maritime capacity. Merchant ships, especially ocean-going merchant ships, have a very long lifespan. Many merchant ships in later generations can reach at least 20 years or even 25 years. Most of the new merchant ships were built in about ten years. If it weren't for Germany's infinite submarine warfare, the Allies would basically not replace the merchant ships. Even if they were replaced, they would be mainly ten thousand ton.

After all, for the Allies now, the 10,000-ton class is the most economical. For this world, the 10,000-ton class is one of the most mature and cost-effective merchant ships. They also know that 20,000-ton and 30,000-ton may be more economical, but in the early stage, it must be expensive. Britain and the United States and others replaced merchant ships, not because the merchant ships were too old or out of date. The reason for them to be further caused by submarines. Although Britain and the United States have not stopped research, there is not much market on the one hand. Sinking a 10,000-ton class is more or less affordable, but sinking a 50,000-ton class is painful. Without giving or investing, merchant ships from other countries in the world have remained below 20,000-ton class.

The economy and cost have become the reason why the merchant ships of ten thousand tons are still active. Even when the war is fierce, performance indicators and other declines are still the case. The reason why the Allies have no money, the United States has it, but the United States spends more money. As for Britain, it is basically impossible to make do with it. In this case, it is basically impossible to make the British and Americans give up their usual merchant ships of less than 20,000 tons and develop merchant ships of more than 30,000 tons or more.

But China is different. Its huge territory and population have formed an unimaginable market. Even during non-war times, the tonnage of merchant ships must be maintained to a considerable extent, especially under the premise of occupying many islands in the Pacific, Australia, and even in fact, controlling the Middle East, countless resources need to be transported back to China for development, which has higher requirements for merchant ships.

Especially in Australia, Australia cannot digest all its iron ore deposits. Even if it can be digested, China cannot place all steel mills in Australia. This is not in line with the interests. Most steel mills will not directly export steel ingots, and most of them will be forged into different shapes. This brings great difficulty to transportation. Building steel mills in a scattered manner can support the surrounding steel needs and avoid super giant steel manufacturers. Once problems arise, the impact can be said to be huge, which is not conducive to China's national defense security.

In the future, iron ore fine powder after preliminary processing and selection can be transported directly to China's coastal steel mills through large, 100,000-ton, or even 200,000-ton bulk ships, which will not waste much freight, but will be easy to control. In this case, the tonnage requirements for merchant ships will be higher, so to a certain extent, it is acceptable to increase the total tonnage of merchant ships, and it will not exist. After the war, a large number of wastes will be lost.

Now, Japan has made a request, and there is a little more. Since Japan is willing to immigrate to at least half of the population, 20 to 30 million people to Alaska, it not only needs to provide food, clothing, housing and transportation for so many people, but also urban construction, industrial layout and other aspects. In these aspects, there are only a very small and very small aspects, which are aided, and most of them are paid services from China. As long as Japan develops well, or Japan can get enough funds from Alaska, or Canada and the United States, then this time and time transportation will not be a loss.

China is now a big business. The increase in overseas control territory and the expansion of scope, from the northeastern Pacific to the northwest, and even the southwest, except for the southeast, the other three angles of the Pacific have been involved in by China. This requires extremely large maritime transportation distances and a large number. Especially in the Pacific, island countries have no foundation and no various resources. If they want to build large-scale airports and naval air force bases, the materials needed are massive, and even tens of millions of tons of ocean transport ships are not enough. In this case, it is natural to put higher requirements on the tonnage of merchant ships.

After the war in the future, as long as Japan does not withdraw from the Sino-Japanese Alliance, this part of the merchant ships can be transferred to Japan. No matter what, as long as Japan does not give up the three islands on its own side, the Japanese island's connection with Alaska must also require a certain number of merchant ships. This part of the merchant ships can be transferred to Japan at a lower price, which is not a waste.

Shipbuilding is not easy, but for China, which has mastered higher production methods, this is not difficult. The popularity and emergence of computers, computer-assisted design and computer-assisted manufacturing have been quite obvious to the improvement of the shipbuilding industry. In particular, the segmented production method greatly increases the speed of shipbuilding. Even merchant ships with more than 30,000 tons are only about the same construction speed as the previous 15,000 tons. After weighing the pros and cons, especially considering China's crazy growth in transportation pressure, China finally approved the construction of a batch of merchant ships with more than 30,000 tons. These ships filled all docks with more than 30,000 tons under the current low naval construction task.

During the fierce period of war, when China and the United States launched a Pacific War and even attacked Alaska in North America, China's large docks were not large warships, but merchant ships. This was the first time that the world encountered, and it also had something to do with China's intensive development. Until now, China's warships have been sufficient, and even the naval personnel are a little insufficient, so slow down a little. As long as the naval personnel come up, the sea of ​​warships can be exploded at any time. In terms of the total tonnage of the dock, China is even much stronger than the United States.

The tonnage of merchant ships will of course increase, and it is also a loss for China to have money at present to launch at least 150 large merchant ships with a minimum of 30,000 tons at one time. For a ton of $300, a ship of $10 million, and a 150 ship is at least 2 billion, and a 54,000 tons is even higher. However, large-scale investment will bring about a reduction in costs. For China, who knows the benefits of economic war, every point saved will become an economic advantage.

Such a huge merchant ship was built and built at an astonishing speed. Before Japan requested, the first batch of almost 50 ships were launched before and after the Japanese attacked Alaska, and after the intense sea trial, they were put into use. For China, professional naval soldiers are a very difficult thing to solve. Until now, some Japanese navy has been used and more naval schools have been opened to use a large number of active battleships as coach ships. In the next two or three years, this number may increase significantly, but now the number of naval ships is relatively insufficient, but ocean-going merchant ships are fine.

I don’t know how much sea fishing and past merchant ship training have been trained. Even if the navy draws, there are enough personnel. Moreover, a merchant ship does not require so many personnel, especially for larger merchant ships, when the tonnage of the merchant ship is increased from 10,000 tons to 30,000 tons, or even 50,000 tons, the personnel used by merchant ships are not three times or five times, but only a percentage increase. 50,000 tons to 10,000 tons can increase by 70% of the personnel, which is already good.

Using fewer personnel to transport more cargo, perhaps larger merchant ships will become targets on the route. However, Britain and the United States currently do not have the ability to strike from a long distance. The only thing they have to defend is submarines. However, according to the information possessed by Germany, submarines that can voyage more than 3,000 nautical miles and have always threatened China's routes.

The Allied Powers were hit by Germany's infinite submarine warfare and thought about studying submarines and attacking supply lines. Unfortunately, Germany had no supply lines. Germany's former merchant ships and cruise ships, or before the United States joined the war, were transferred to China. After all, Germany could not even have a navy to get out of the Baltic Sea, let alone merchant ships. Send it out was a target. Therefore, Britain did not attack the subjectivity of German merchant ships. As for the United States, the same is true. That is, after declaring war on China, they felt the threat of China to supplement Germany. They began to consider studying submarines that were ocean-going, specifically targeting route attacks. Unfortunately, a mature submarine could not be developed overnight, especially when the Allied Powers had no foundation. Now they have just created some small-tonnage offshore submarines, which cannot threaten China's waterway safety for the time being.

After about 2 weeks of trial sailing, the new merchant ship has been very effective. Not only has the capacity increased significantly, but the flexibility of operation and airworthiness have increased considerably. The most important thing is the speed. Compared with common merchant ships, the most economical speed exceeds 1.2 knots, and the maximum speed will exceed 2 knots.

For merchant ships, such speed improvement is very considerable. Speed ​​and tonnage are also in the category of efficiency. In the face of war and in the face of large-scale ocean transportation, any slight improvement is also quite considerable. This means that in the same time, more cargo will be transported, reducing time consumption, and even reducing time costs.

After a simple launch drill, the first 50 30,000-ton merchant ships were sent to Japan. They will work with the fleet that returned to the ship to Alaska together with the previous return flight to jointly undertake the task of transporting supplies to Alaska. Once the huge warships docked in Tokyo Bay, they caused a sensation. Japan dismembered the navy, but the experience of building the King Kong-class made many Japanese people knowledgeable. Even if it was just a merchant ship, it was significantly different from the 10,000-ton one. It was really like the comparison between a fat man and a thin man. Any Japanese who saw this merchant ship would exclaim the big guy at the same time. (To be continued.)
