In the middle and lower reaches of the Yangtze River, the waterway of the Yangtze River continues to widen, deeper water depth, so that the sea vessels of more than 10,000 tons can be passed here, the Yangtze River waterway in the northwest is regarded as the most important artery in the future, and even the bridge that crosses the Yangtze River has chosen the most difficult construction, the bridge height is more than 65 meters of extra-large high bridge, in order to ensure the ability of the Yangtze River to pass 10,000-ton cargo ships in the future, and thus the main artery connecting the north and south, on the Yangtze River, is cut off, the Yangtze River is still a moat, but the cities around the Yangtze River have increased a lot.

At night on the Yangtze River, there is silence here, except for a few hours or so, there is a night sailing ship, the rest, it is calm. In the night, a huge guy, slowly rising from under the water, thick body, larger than the shape of an ordinary submarine cigar, this is the training submarine force of the transport boat force, the appearance, some like the ocean-going submarine coarse version, but obviously, the speed of the surface is much faster than the underwater, obviously, in the structure, with reference to the study of fluid mechanics, the pursuit of more wide, surface speed, diving, is just a temporary choice, in order to avoid the confrontation head-on.

This is the submarine transport force named Cow in later generations, in a world-class war, Cow from scratch, from the most ordinary 500 tons of transport capacity, gradually increased to 3000 tons, or even 5000 tons, although the economic performance of the transport submarine is far inferior to ordinary cargo ships, but the ability to dive and cross certain blockade lines is enough to make it develop into a series.

Today, cows don't have posterity nicknames. It has only one agreed number, the Chinese character 1914 submarine, compared to the military submarine hunting submarine like the famous general. It looks a little shabby.

On the entire Chinese character 1914, there are only two 333 mm torpedo tubes for self-defense, and two 88 mm deck guns are fixed on the deck, which is completely different from ordinary submarines, which only have torpedoes, ignoring deck guns to increase underwater performance. Above the surface, it is possible to deal with all unarmed ships, below the surface. The depth of 40 meters of dive, in the battle, does not have much effect, just the effect of crossing the opponent's blockade line.

When coming from the water. Up to a week of maritime training. This group of 12 submarines has completed the necessary subjects and is preparing to return to the Jiujiang base, at this time, the telegram from the northwest came, and it happened to be night, and there were relatively few ships on the Yangtze River. The submarine returned from the present place to the base of Jiujiang, with a range of more than 100 kilometers. It can only drive at night, but at a speed of about 18 knots, it can reach Jiujiang in a few hours at most.

Jiujiang base, this small city along the Yangtze River, was once just a very inconspicuous place, with the help of the northwest, quietly appeared a dock, from 1912, to now, less than one and a half years, Jiujiang has really become China's largest submarine construction base.

Relying on the Jiujiang Shipyard, on the surface, it is just an ordinary shipyard that produces river boats and small sea vessels below 1,000 tons, with an annual shipbuilding capacity of only about 30,000 tons, but the actual, semi-submersible, submersible docks have at least 72, the largest is 2,500 tons, and the smallest is more than 1,000 tons.

Originally, submarines were small ships, the largest of which was just over 1,000 tons, and after showing their role in Europe and the war against Japan, the navy found that it seemed that submarines might become a decisive force in the defense of China's maritime frontier before the capital ships were commissioned, at least until the main fleet was commissioned.

In fact, in later generations, submarines are also known as the defensive weapons of weak navies, he does not have the aggressiveness of offensive missile ships, nor does he have the versatility of aircraft carrier formations, but a conventional and nuclear submarine force with combat effectiveness has always been China's last guarantee, and the low cost, low operating cost, and high efficiency of submarines are the only choice for weak countries.

The Northwest is not weak, the Fantasy class and Orion have been changed, proving that the Northwest can produce more than the capital ship of the warship, the Fantasy class is a concentration of German design and the Northwest raw materials and power system, even if it is compared with the so-called perfect class, Queen Elizabeth class, it is far exceeded, as long as a batch of capital ships are in service, the Northwest can immediately become a naval power from a weak country with almost no navy.

But what to do in the past one year, Japan was taken by surprise by the northwest in the battle of Shandong, using the help of 15-inch land defense batteries, killed most of the combined fleet, and dealt a heavy blow to the Japanese, the Japanese still have a lot of old fleets, and Japan with decades of naval tradition can also signal reserves and mobilize forces from civilian sailors, so Japan is also a huge threat to China.

China and Japan are almost connected, the one who knows China best is Japan, and the one who knows Japan best is also China, especially Cheng Biguang, a group of naval officers who once participated in the First Sino-Japanese War, they know very well that when the war situation cannot be changed and Japan suffers a big loss, Japan will take risks, what Beiyang, what revolutionary party, what allies, when there is enough blood, the Japanese will not care about anything, the north can't break through, then the south, or even just suicidal aggression, It was enough to make the south of China a sea of fire, and in the First Sino-Japanese War, even with the mediation and opposition of Britain and France, Japan still launched a land war against China, and finally won the victory.

The northwest is far from the mainland, and it is not afraid of Japan, but in North China, the middle and lower reaches of the Yangtze River, and even Fujian, which is across the sea from Taiwan, it will be difficult for the Japanese to transfer the Northwest Army everywhere, and it is particularly important to have a ship's mobile strength at this time.

There might have been a fleet in the northwest, in order to get Qingdao handed over to Germany, Cheng Biguang and others also knew that this was a helpless choice, even if they stayed, the northwest simply did not have enough people to operate these fleets, that is, relying on this, almost half a year of sea trials, the northwest sent at least 2 batches of people, a total of 30,000 people on board, now, as long as now, as long as the fleet in the Qingdao dock is produced, the northwest has enough personnel to operate, so that the fleet will become a real combat effectiveness. It will take at least a few months, and even after the sea trials, it will take a few months before it can really play a role, and during this vacuum, only Sanhai can be relied on.

With the help of the northwest, the refit of the three seas has reached the extreme, 5,000 tons, and even 7,000 tons of ships are not his opponents, but there are too few, only 3, Japan still has a few ironclad ships that were mothballed before 1900, and once these are unsealed, the three seas are not opponents.

In addition to the shipyard, Jiujiang is a large submarine training school, as far as possible to improve the combat capability of submarines, under the premise that the sea surface forces do not have sufficient detection capabilities for submarines, even if it is far stronger than Germany, Britain has suffered a big loss under German submarines, not to mention Japan, which is far inferior to Britain's naval strength, and advanced submarines in the northwest. Dozens of submarines may not have much destructive power for the main fleet of 10,000 tons, but hundreds, or even thousands, of submarines that launch eight torpedoes in a short period of time in a row, once the number reaches a certain order of magnitude, it is a sea of torpedoes.

Attention from top to bottom, so that the development of submarines, very rapid, the battle of Shandong, only a few dozen, in just two months of less than a case, there are 92 more, the total number of submarines crossed the 100 mark, the most important thing, considering the possible blockade, the northwest chose the 1300 tons - 3000 tons of transport submarines, almost in October 1913 finalized, and the first batch of 12, displacement of about 1300 tons, carrying capacity of 500 tons of transport submarines.

The commanders of these submarines are either drawn from the previous combat submarine formations, or they are recruits, and the transport submarines do not perform combat missions, and the requirements are much lower than those of combat submarines, and some simply only receive one or two months of recruit training and get on board, as long as the ship can drive away and know the entire operation procedures, it will be OK, and there is no need to intensify training.

A few hours later, when the submarine that went out for training finally rushed back to the Jiujiang base, the submarine was taken over by the transport team, and all their crew members had 18 hours of rest to recuperate and deal with personal affairs, and then they needed to set off immediately, and their destination was Taiwan, which was far away at the other end of the strait.

Now China, is no longer the original, even matches have to be imported into China, 6 years, the northwest has changed the whole of China, and even gradually changed the world, strong production capacity, so that the materials can really be described as piled up, not only a large number of exports, but also piled up in the country, in the northwest of the various military warehouses, even in the Jiujiang warehouse there are a lot, take Jiujiang as an example, at least 10 divisions in addition to artillery weapons are stored, transfer a part, there is no problem at all.

After receiving the telegram, preparations were made, the military warehouse was quickly mobilized, so that the materials were transported from the warehouse to the dock in a short time, and then loaded into the ship with the help of the logistics force, one by one was fixed into a one-meter square box in a small container, perhaps put 50 rifles disassembled into parts, or put a large number of bullets, or put a few mortars and shells, the container was easy to place and load and unload, a little bit filled into the transport submarine, on the dock, the draft is very shallow transport submarine, Gradually deepened.
