The speed of the Chinese survey in Constance is quite fast, the port project is placed after the dock manufacturing, hundreds of docks of different sizes, only 4 are 6000 tons, the rest, all are more than 1000, more than 2000 tons, which is very difficult for the rigorous Germans, but for the Chinese, especially for the construction team sent to Cons survey, this is simply a housekeeping skill.

In the past few years, this construction team has been building a dock, starting from the Jiangnan Shipyard, the civilian 5,000-ton dock, for the first breakthrough, completed the creation from scratch, China's first tonnage of more than 5,000 tons of mixed cargo ships, is opened in this dock.

Next, with the Northwest getting more information, steel, machinery, and even the original German dock drawings, their technology began to make a series of breakthroughs, from the 10,000-ton and 20,000-ton military docks of Qingdao Shipyard, to the final, 30,000 tons, 50,000 tons, and even 70,000 tons of docks, they almost single-handedly created China's shipbuilding system, and even included Lanfang, and the German Bavaria-class currently being manufactured in Lanfang was also constructed and sun-mounted through the 30,000-ton and 50,000-ton docks they made, which will be put into use soon.

From just coming into contact with Jiangnan Shipyard to now, in just a few years, this dock construction team has also achieved tremendous development, becoming a huge team with at least 2 million technicians.

The maximum dock is only 6,000 tons, but speed is the key. Only when speed is guaranteed, there is nothing else. The Germans wanted to send troops before October, after the capture of the Constance survey. It was already the beginning of May, and with the time on the road, it was less than 5 months, which was a huge test for the Chinese construction team.

There was not much time left for them, one month to build a dock, and a maximum of five months to take out all the escort ships and transport ships. Originally, it was expected to be able to get supplements from Turkey and the Mediterranean, but after Turkey joined the Entente, the situation of the Allies in the Entente was almost a sharp turn, and several of Turkey's capital ships, which were originally responsible for the confrontation with the Entente in the Mediterranean, were now all joined by the Entente. Turkey has now left all its warships in the Black Sea Straits and strengthened the Dardanelles as much as possible, and even ordered 120 15-inch naval guns from China.

Actually, about the Dardanelles. Previously, Turkey's opinion was very ambiguous, after all, Turkey and Italy are united. On top of the new capital ships, Turkey and Italy have a total of more than 5 dreadnought ships. Together with the other warships, it was enough to overwhelm the Mediterranean Fleet of the Entente without Britain.

But after the absence of Italy. Only two Turkish ships remained, and in addition to the training and fighting, they did not dare to go out at all, for fear that the whole Entente army would attack, and they could only strengthen the defense of the Dardanelles.

The Dardanelles Strait is part of the Black Sea Straits, and it is also the most important maritime hub of Turkey, holding the passage of the Black Sea into and out of the Mediterranean, and its own defense is tight enough, but most of the batteries were built in 15, or even 20 years ago, against the cutting-edge super dreadnought, there are still some deficiencies, if the British really come to attack, with the firepower of the super dreadnought battery, you can achieve targeted elimination, in this case, the Turkish leader, can only strengthen the defense, in the middle, Even the 15-inch naval guns imported by the Germans became the unyielding choice.

The Chinese, who know the purpose of the Germans, of course, know that at present, Turkey, and even the important role of the Dardanelles, strengthening the defense of the Dardanelles, is also proposed by China, and now Turkey has taken the initiative to put forward this, then even if it is the intention of China, anyway, to the German side, to send 15-inch naval guns, by the way, to prepare some for Turkey, such high-precision things, the price has always been extraordinary, in terms of cost, the profit of this artillery, at least 2 times more than 8 inches of artillery.

A large number of artillery guns were continuously shipped into Turkey, strengthening Turkey's defenses, I have to say that in the future, after the failure of the Entente in the European continent, the intention to open a gap from Turkey went bankrupt directly, and the excellent performance of the 15-inch naval guns conquered the Turkish army and navy, and even the navy at the end of 1915, specially ordered two Orion warships from China, which also opened the way for the export of China's large naval ships to a certain extent, and the future direction is not only Germany.

At this time, Constance survey, among the four largest docks, the construction of shallow water heavy gunboats, is entering the end, before the construction of the main body of the entire hull is completed, the reservation of the turret has also ended, just waiting for the arrival of the artillery, and now the artillery has also been shipped, with the design of the construction of China, just need to weld things to the ship on the line, after the development of electric welding in China, and accompanied by the exchange with Germany to Germany, electric welding is not only a worker holding an electric welding machine, metal bonding, he has a lot of processes and types of electric welding, Even China is groping, not to mention Germany, the application of the most basic oxygen welding in Germany, but has surprised the Germans, in the connection that does not require strength, with oxygen welding, the efficiency does not know how much to improve.

Relatively speaking, China is more professional, and even on shallow water heavy gunboats, every process, every production step, there are strict regulations, and the workers only need to follow the process smoothly, and it is enough.

The shallow water heavy gunboat is not a product of just design, a series of adjustments are needed, this is a product that has been quite mature in China, all the parameter sizes, and even the premise that the design has been completed, just do it, even the cutting and parts production of these things, not done in Germany, are produced in China and take it, just talking about machining capacity, in China, which uses high-speed steel lathes, has surpassed Germany, not to mention that it has begun CNC groping, Some simple chip CNC machine tools have begun to be used, although they can only process some standard parts, but they have greatly accelerated the basic efficiency.

No, the construction of the dock, with the efforts of the high-quality construction team, took only 23 days to complete, and at the same time, a large number of parts and equipment were transported through the 3B railway, and the work of the dock here is a welding and splicing work, so that a 6000 warship can be completed in only a few dozen days. The exact number is 47 days, which is a little more than a month and a half, which is amazingly fast.

3 days after the ship's gun battery was transported, with the efforts of the staff, after the battery was on the shallow water heavy gunboat, these 4 ships were completed, and then, there were 4 more ships, however, the tonnage should be small, after all, the time is limited, there is no longer 50 days, and the naval guns used will also be reduced to 13.5 inches, but the reduction of the caliber of this gun will reduce the overall tonnage to about 4800 tons, almost 20% reduction. Smaller tonnage, means that the efficiency is improved, even if it is just the process of welding, it will be much simpler, which is inevitable.

In fact, if it weren't for the first batch of requirements for shallow water heavy gunboats with 15-inch guns, China would recommend all 13.5-inch ones, with the degree of protection on the Black Sea coast, 13.5-inch and 15-inch ones, there is not much difference, they are all one-shot defenses, and the size does not matter much, but because the 13.5-inch production cycle is short, it can be a few days in advance.

To be honest, a few days in advance, this proposal did make Germany moved, but after weighing, it was found that the advance was less than 15 days, and even tonnage protection and many other aspects were insufficient, and finally, under the study of the German Admiralty, the first batch of 15-inch guns were used to ensure the power of the first wave.

The twin guns were welded to the small boat of only 6000 tons, how strange it looks, the 6000-ton boat pulled up the 15-inch gun, it is not impossible, According to a 28,000-ton class of 9 guns, this proportion is not too high, but the proportion of the navy can not be calculated in this way, is it difficult, your 6,000 tons of protection, power, is only a quarter of 24,000 tons, this is completely impossible, the larger the tonnage, the larger the volume, the larger the things that can be accommodated, but the smaller the use rate per unit weight, which has been scientifically proven, but this best effect needs to be calculated. Even if 6,000 tons can, in the eyes of professionals, how strange it looks, especially in the eyes of some people who understand the navy, it is even more so.

In the next few days, the manager saw the power of the shallow water heavy gunboat, such a powerful, small boat with twin 15-inch guns, the speed is not slow, at least 14 knots, not as the manager thought before, only less than 10 knots, so that he can barely keep up with the capital ship, anyway, he does not have any escort role, and can even set off with several ships first, so that when the time comes, you can arrive almost at the same time, and use the shallow water heavy gunboat to suppress the fire on the shore, Then the implementation of the landing, for Germany, the most difficult, always before the landing, as long as the German army can land on the shore, then everything is not a problem, the German army is strong, can defy everything, unless it is like Bordeaux, the two sides spent a huge amount of experience to build a group of trenches, otherwise, any line of defense, can not withstand the German attack, for this, any German officer is quite confident.
