After Fabian and the three of them went back, they entered the busy, changing the drawings, fine-tuning the structure of the hull, welding will reduce a lot of excess weight, for the giant ship built of steel, the reduction of one percent is very large, not to mention 10%, even if the shell welding is not considered, it is at least about 5%, this part of the reduction, will be the center of the ship and the mechanical balance, re-test, must calculate the balance method.

The total weight of the fantasy design is carefully calculated and relatively perfect, this part does not have to be reduced, the only problem that needs to be considered is that the weight of this part, almost more than 2,000 tons, needs to be added, whether it is the increase in crude oil in the reserve warehouse, or the armor belt, there will be a huge increase.

After weighing the pros and cons, this part is temporarily placed on ammunition and crude oil to increase the continuous combat and endurance of the whole ship, the reason for this choice is very simple, that is, the armor is already too strong, almost no naval guns can break through the armor of his conning tower and turret head-on, the deck can be increased a little, but not too much, it is easy to cause instability of the center of gravity, and it is a natural choice to increase the endurance and sustained combat ability, taking into account all directions.

The whole modification process lasted a total of 15 days, during which Yang Yuanzhao needed to do was to ensure the logistics work, various new processes, processing methods, and even for the whole of the battleship, the introduction of parallel engineering, this basic principle, has been used in Jiangnan Shipyard, after the use of parallel engineering, the efficiency of Jiangnan Shipyard. On the basis of the original, it has been improved by more than 4 percent, and I want to come. It will also help here.

Experts specializing in this field, in 15 days, a detailed understanding of the overall drawings and construction technology of the fantasy level, combined with the experience of shipbuilding, as well as the current situation of Qingdao shipyard, finally came to a conclusion to give a conclusion, under the existing situation. With the use of concurrent engineering, the efficiency gains are not high. That's about 5% at most.

Such an increase did not satisfy Yang Yuanzhao, and after repeated inquiries, parallel experts also mentioned a statement, that is, if two ships were built together. It can be increased by about 5%, 3 ships can be increased to 8%, and the lifting efficiency of 7 ships built together is the highest, reaching about 15%, and can be interspersed with some 10,000 and 20,000-ton ships and a number of ships below 5,000 tons, and the overall efficiency can be increased by about 22%.

22%, for a battleship, under normal circumstances, the time of production in the dock is between one and one and a half years. A 22% increase is almost a saving of more than 2 months, for the production of battleships. The key to comparison, some small boats with a small utilization rate of the dock, even more so, the time saved is efficiency, which brings about a reduction in overall costs.

Seven ships were built at one time, at the same shipyard. The biggest improvement in parallel engineering is always within a small area. It is also possible to carry out a wide range of workers across the country, and some of the more commonly used worker transfers and mobilization, material mobilization, etc., will increase costs. But it is much more difficult to choose, this is a battleship, not an ordinary merchant ship, from the beginning of construction, it needs to spend money on battleships, after completion, it will cost more, China is still just starting, naval sailors have not yet appeared, before Yang Yuanzhao envisioned the fleet combination, just prepare 2 battleships as the flagship of the fleet, 7 at once, the cost is reduced, but the total investment has risen to the level of unaffordable, can not put 3 battleships back as reserves.

After careful consideration, Yang Yuanzhao finally opened the plan of 5 ships, first 2 ships, and the remaining 3 50,000-ton docks, which will arrive here a month later, all of which are Yang Yuanzhao's decomposition, 70% of the dock structure, processed by the steel plant and the machinery factory, and the rest need to be synthesized by Yang Yuanzhao's all-in-one machine, and the 50,000-ton dock is enough for China for the time being.

In addition to the 50,000-ton dock, other docks are also under intense installation, a battleship, can never conquer the world, needs a system, ships other than battleships, Yang Yuanzhao did not let Fabian they spend energy to improve, almost took the idea, about 30,000 tons, directly applied the British Orion, power, naval guns and armor using new materials from the northwest, after the introduction of electric welding technology, it has been greatly improved, almost a makeover, the artillery also uses the King Kong class 14-inch gun, The changes are minor, and almost fine.

5 Fantasy class, 4 Orion reforms, 8 17,000-ton large fast cruisers, 12 5,000-ton light cruisers, and 54 destroyers, this is the Northwest's huge shipbuilding plan in the next 2 years, especially destroyers, in Yang Yuanzhao's plan, how much can be built.

Of course, this is not all for the sake of military expansion, in the northwest plan, the future core fleet will be composed of 2 Fantasy class, 2 Orion, 4 large fast cruisers and 4 light cruisers, destroyers will be divided into two parts, one part will form a separate fleet, 12 ships, and the other 8 will be grouped into a large ocean-going fleet.

This kind of arrangement, in this era, is somewhat advanced, this era is generally organized according to the type of ships, such as the fast battle patrol formation and the capital ship formation, this is the formation of the Jutland Sea War, cruisers and destroyers, this kind of can not occupy the battle line, are a separate group, in the battle team, play a limited role, that is, in the World War II period, with the rise of aircraft carriers, a single aircraft carrier, can not achieve perfect protection, there will be escort warships composed of aircraft carrier battle group, In this way, such a group was formed.

The remaining warships, Yang Yuanzhao did not plan to stay, he planned to sell, to give the natural buyer next to him, these ships can form a powerful fleet in an instant, and even in terms of strength, not weaker than the main fleet of Britain and Germany, 3 fantasy-class and 2 Orion, absolute capital ships, even if they are placed in the Battle of Jutland, they are also proper capital ships, core ships, plus other ships, completely destroy the British fleet except for the home fleet, after the Far East, what will happen.

Germany does not buy the situation, Yang Yuanzhao will not think about it at all, this is almost impossible, the comparison of the capital ships between Britain and Germany, Germany has been in a position of catching up, there is a chance to approach and surpass at once, including 3 epoch-making fantasy class, in order to end the war, it is almost impossible for them to refuse, in the early days of World War I, Germany was still very rich.

The entire ship-building plan is handed over to parallel engineers to calculate, 5 Fantasy-class and 4 Orion are the main ship-building plan, and under mutual coordination, the total efficiency can be increased by 14.5%, plus other ships, the overall efficiency can be increased to 18.7%, but the efficiency of the capital ship will be slightly slowed down, only 12.5%.

This kind of efficiency is okay, but when the cost is recalculated, even Yang Yuanzhao can't help but take a breath of cold air, the industrial strength of the northwest is now extremely amazing, and the cost of Jiangnan shipyards has been compressed to more than half of other shipyards in the world, but the battleship is a beast that swallows gold, even the cost of the northwest can't be reduced much, mainly on manpower, and on materials.

Through the careful calculation of the actuary, the construction of a fantasy class, the cost reached an astonishing 19.5 million Northwest Dollars, almost settled to about 40 million Deutsche Mark, Orion changed, because of the addition of a lot of things unique to the Northwest, the performance has been quite improved, the cost has decreased slightly, 15.5 million Northwest Dollars, large fast cruisers reached 6.7 million, light cruisers about 2.5 million, destroyer class 950,000.

Such a cost, among the warships of the same level, the price is so low, almost in the forefront of the world, but Yang Yuanzhao started the ship-building plan is too huge, close to 300 million, that is, 30 million pounds of one-time ship-building investment, even Britain does not dare to be so wealthy, the key is that the total amount of ship-building is as high as 600,000 tons, which is not only a huge test of ship-building ability, but also a huge test of the heavy industry system in the northwest.

Soon, this plan was decided by Yang Yuanzhao, as the leader of the northwest, but also as the richest group of people in the whole world, in terms of funds, Yang Yuanzhao has never had a problem, as long as he does not use the money of the consortium, use his own money, almost he can pat his head, the ship can be built first, after it is built, whether it will be incorporated into the navy, can be postponed.

Yang Yuanzhao's investment is more than that, next, he will spend 100 million US dollars, in Germany, the United States, the United Kingdom to acquire a large number of second-hand ships, are 20 years ago, can be sold scrap iron, as a training ship, on the surface, is to rebuild the Chinese Navy, but in fact, this will become a naval school training ship, in addition to Qingdao, the largest naval school, in Shanghai, Mawei, and even Guangzhou, will secretly establish a naval school, and the construction of the ocean-going fleet is also being prepared, up to 3 years, China will have a navy with a fleet of four capital ships, more than 100 ships of all sizes, and all the officers of all ranks they need.

Compared with building ships, this part of the investment is greater, the training consumption of military schools and training ships themselves, as high as about 50 million every year, this amount, will continue to increase according to the passage of time, this Yang Yuanzhao is very clear, but he still did not hesitate to approve, this is related to the future of China's maritime security and strategic position of investment, not to mention 50 million, 500 million he will also invest.

The approval of the shipbuilding plan, especially when the two docks were completed, the first keel had been laid in the dock, the time, it was December 24, 1912, the day before Christmas, after quietly participating in the groundbreaking ceremony, Yang Yuanzhao did not stay too much in Qingdao, he quietly returned to the core of the northwest Baotou, the dream of the Chinese navy, so quietly opened in Qingdao.
