At present, in the secret submarine manufacturing plant in Jiangyin, among the two docks of less than 2,000 tons, two relatively small submarines lie in the middle of the dock, they use a typical submarine structure, the submarines of World War I and World War II, there is not much difference, that is, in later generations, with the deepening of materials and computers, fluid science and so on appeared in the submarine, greatly reducing the resistance during operation.

Some submarines with the same speed on the water in later generations, and even submarines with underwater 'sex' can be better than those on the water, Yang Yuanzhao's has heard of the famous water droplets, but this kind of modeling is useless now, even if Yang Yuanzhao has a computer, there is no number jù and basic theory to support the calculation, and there is no large number of researchers.

Of course, for the existing submarine drawings, it is not simply copied and enlarged, Yang Yuanzhao also summoned personnel and made improvements to it, first of all, the deck gun is gone, the submarine is to rely on torpedoes, when the submarine really wants to use artillery, it is unthinkable, just a gunboat can completely explode him, as for the breaking 'handover' operation, the deck gun may be able to capture more merchant ships, which is the only role of deck gunfire.

However, from the very beginning, Yang Yuanzhao positioned the submarine to focus on breaking the "handover" and surprise attack, showing the advantages of "color" in power and battery, and the northwest can even create a submarine that is stronger than the United States in World War II, increasing his endurance and sustained combat ability, especially the power and number of torpedoes is the key, a torpedo is a ship, a few more torpedoes are not good, the artillery on the deck will definitely affect the underwater speed of the submarine.

In the semi-submersible concealed dock of Jiangyin, two submarines are under intense construction, and have now entered the end, this is an 800-ton submarine, which thoroughly uses the electric welding process, and the reduction of rivets on the surface will make him less resistant to water. The speed will be faster, the underwater endurance will be stronger, with the technology of the 21st century, there is a huge propulsion in the material and electrolyte of the battery, the process of the battery, especially the process of ordinary batteries. From 1900 to 2000, there was not much improvement, but there was a lot of improvement in efficiency and capacity. In a hundred years, countless geniuses have been invested in the field, Yang Yuanzhao can be said to stand on the shoulders of all 100-year-old giants IQ, the capacity of the battery, compared to the mainstream world battery, has risen by at least 4 times, plus the volume reduction, the increase in the proportion of the battery, and the expansion of the hull. It can increase the battery volume, and the total battery capacity is increased by 12 times.

12 times the battery, double the weight, the increase in drag and power demand, absolutely not doubled, in this way, about 800 tons of submarines. The range under water has increased by 3 times, and the travel speed has also increased by more than 2 knots, which may seem inconspicuous, but it is enough to make a huge difference in the submarine.

Such submarines, even if accidentally detected, have a higher underwater speed. It can also make the submarine escape faster, because in this era, the only thing that can measure underwater submarines is sonar. In 1906, Lewis of the British Navy invented sonar, which could easily measure the sound of a submarine's propeller in a pond tested by the Navy. I thought it was a sharp weapon to deal with submarines, but I really found that reefs, sea 'waves', and even some fish can affect the play of sonar, this kind of primary sonar, is a 'chicken' rib like a storage zài, so even a few years later, sonar is also an auxiliary means, the way to deal with submarines is often the submarine 'fire' torpedo, periscope and other active leaks, and then rely on the range effect of depth charges to attack the submarine.

The stereotyped submarine was brought to the front of the German submarine designer, and he was directly dumbfounded, the German submarine research was also going to enlarge the tonnage, because the submarine of three or four hundred tons did not have much effect, and the tonnage of the U-9 submarine had been enlarged to several hundred tons, but the huge pressure brought by it, the battery and the power, and then expanded, perhaps, the submarine was a slow-moving iron can, and it would not work.

The number of submarines taken out by the Northwest is difficult to judge, and the clear power and battery energy on it proves that he can achieve it. As a submarine engineer, he also has some knowledge in terms of ships, and he has also heard of some of the overall number of the fantasy class, all of which served in the Admiralty, and both sides know the roots, even if he is only a submarine engineer, the 45,000-ton super dreadnought has been completed in the northwest, maybe he really has expertise in these aspects.

It is this kind of idea that allows the designers not to ask too much about some problems of the submarine itself, such as batteries, shells, pressure-resistant shells, electric motors and diesel engines, but only to judge some basic numbers of the submarine itself, and put forward a series of opinions.

With the help of the designer, these opinions have been finely adjusted to the submarine, and the overall structure is more reasonable, and the whole ship has been formally defined as "nature", and the time spent on "spending" is less than 10 days.

The total weight is only about 800 tons, and such a submarine can be done in a small dock, and even has a lot of experience in the processing of this tonnage. For ordinary ships, the outside is very difficult to connect, but the internal welding, but has a huge advantage over the willow joint, once the shell is formed, the interior can be divided into several processes to carry out together, which greatly saves time.

The state of the submarine is different from that of the big ship, his curved surface is more, and it is more difficult to process with willow joints, but it is unique with welding. The welding of the curved surface, coupled with the existing shipbuilding experience, made the construction very fast from the laying of the keel, at most 25 days, the submarine was basically formed, the battery and diesel engine, are ready-made, the diesel engine is two 1500 horsepower diesel engines in parallel, a total of 3000 horsepower, as for the electric motor, it is 2000 horsepower.

With a weight of 800 tons, this power is very amazing, after a simple calculation, the speed on the surface can reach 17.5 knots, the underwater speed can reach 11.2 knots, the economic speed of 8 knots can sail 9200 kilometers, and the economic speed of 6 knots underwater can travel 220 nautical miles.

Such a speed is very amazing, the former is also reversed, nothing more than the amount of fuel, how much power, the latter is a real test of the battery pack, it can be said that at least seven or eight times higher than the current German U9, 220 nautical miles of underwater sneaking, enough to ensure the safety of the submarine, no destroyer, when dealing with submarines, chase out more than 100 nautical miles, because of the potential seawater, there are many options, sneaking 220 nautical miles, enough to escape many layers of encirclement.

The firepower installation is to choose a 450 mm torpedo, the front and rear 2 of the firing 'firing' tube, a submarine can be equipped with a total of 12 torpedoes, more than other submarines are equipped with more numbers, and the ability to continue combat is also stronger.

Such submarines, in a sense, have reached the extreme of the current submarines, even if Germany in a few years, because of the infinite submarine warfare attached importance to and equipped submarines, their power is definitely not as good as this, speed and endurance, but also hard "sex" indicators, it can be said that this design has been a complete success.

Yang Yuanzhao went to Jiang'yin', but for the completion ceremony of this class of submarines, this one is temporarily positioned as a general-class torpedo boat, which will be named after the famous general in Chinese history, and the defenders of these two ships are temporarily named Qin Qiong-class and Cheng Biting Jin-class, these two are the image of the traditional Chinese 'door' god, which is well-known in China, and can be said to be known to everyone, and it is more appropriate to name the first batch of submarines.

To be honest, Yang Yuanzhao didn't expect that the submarine would be built so quickly, although it still needs to be gradually sea trials, which may take 3 months to half a year to be completely completed, but for China, it finally has a Zhengyang force that can protect itself.

In the report sent to Baotou by Jiang 'Yin' and the special 'gate' that accompanied the submarine factory, it also mentioned some shortcomings of this submarine, and according to the navy, the only deficiency of this submarine was torpedoes. The main attack force of the submarine is torpedoes, but there is no tradition of making torpedoes in the northwest, and the technology of manufacturing torpedoes is not up to par, and the torpedo is a great shortcoming in the northwest, although as early as before the First Sino-Japanese Naval War, the Jiangnan Machine Bureau has begun to imitate torpedoes, and those torpedoes are all early torpedoes, only a few hundred meters of 'firing' range, and the speed is not fast, and now Yang Yuanzhao can 'get' it, which is the current 450 mm torpedo in the mainstream of Britain and Germany. The range is within 3-5 km, and the speed is between 26 and 32 knots, which is a relatively reliable torpedo.

Of course, there are larger torpedoes, most of those torpedoes are mounted on destroyers or even battleships, after careful differentiation, even if it is an 800-ton submarine, or even a submarine of about 1500 tons in the future, it is not very suitable to install a torpedo 'firing' tube for a battleship, there is not such a big place, it may be under development, and the 533-mm torpedo comes out, it is even more suitable.

There is no tradition of torpedoes in the northwest, and can only rely on Yang Yuanzhao to provide drawings and physical objects to imitate, this in the submarine program opened, these things have been 'handed over' to the Naval Research Institute of the Heavy Weapons Research Institute for research, the current northwest has, except for a part of Yang Yuanzhao's copy of the torpedo, is directly purchased from Germany, the number is enough for 30 submarine formations to use for a year, but this feeling is very bad, must complete self-production, otherwise when a series of 2,000 tons of dock settled in the river' After the yin', after the outbreak of production capacity, it will be controlled by others.

According to Yang Yuanzhao's estimates, only 50-60 submarines can guarantee China's maritime frontier of more than 18,000 kilometers, especially after the future Southeast Asian strategy emerges, the number needed will be even greater -- 73,175 + dsuaahhh + 30498536 -- >
