In the blueprint, a submarine resembling a cigar jumps onto the paper. This is the first-class submarine of the Northern Navy, and Wu Haoxuan also put forward a lot of opinions. For example, German engineers suggested installing a 75mm cannon on the foredeck of the submarine, but Wu Haoxuan rejected it.

The strongest weapon of the submarine is the torpedo. If you install cannons on the deck, you will not pose a threat to those large-tonnage warships. Even a single destroyer could easily sink all of these submarines with artillery, and at most it could only be used against merchant ships. With the current technical conditions of the Northern Navy, it is not yet possible to build a large ocean-going submarine, and this first-class submarine can only be regarded as a coastal defense submarine.

It is precisely because of this that there is no need to install cannons on submarines, and it is enough to use torpedoes directly against the main battleships of the Japanese Navy.

Combining these factors, this is the design of this first-class submarine.

The first class submarine of the Northern Navy, named the 'Squid-class' submarine. The displacement is 220 tons above the water, 290 tons underwater, 30 meters long, 3 meters wide, 4.8 meters high, and 2.4 meters draft. The maximum depth of the dive is 50 meters. Propelled by two 40-horsepower gasoline engines and two electric motors, the maximum speed is 10 knots at the surface and 4 knots underwater. The surface range is 500 nautical miles, and the underwater range is 30 nautical miles. It is armed with two 533 mm torpedo tubes, capable of carrying six torpedoes. The 533-mm torpedo, which is a heavy torpedo, is an extremely strong threat even to the battleships of the Japanese Navy. If you get hit, you will have to be hit hard, even if you don't get sunk.

Of course, with the technology of the Northern Navy, it was not yet possible to produce a heavy torpedo of this caliber. This is a heavy torpedo jointly developed by the Northern Navy and the German Navy. The Northern Navy has acquired all the production technology and equipment and is expected to be able to produce it on its own soon.

Performance of the 'Squid-class' submarines. It's very simple. With a voyage of 500 nautical miles, he can only circle the western part of the Yellow Sea, or even go around the coast of Japan. Of course, as a coastal defense, it is barely enough. Especially if there are more than a dozen submarines, ambushes are the only way for the combined fleet of the Japanese Navy. It will definitely make the Japanese Navy pay a heavy price. In addition, in the next war, it is very likely that the Japanese Navy will launch an attack on Arthur, so these submarines will be able to wait outside Port Arthur.

Of course, in order to further strengthen the power of the Northern Navy, it is also indispensable to develop larger submarines. In the future, the Northern Navy must have submarines capable of conducting ocean-going operations. After all. Japan is nothing more than a small enemy. If China is to compete with the United States for hegemony in the Pacific in the future, a submarine that can go to the Hawaiian Islands and even the west coast of the United States will be indispensable.

"The performance of the 'Squid-class' submarine is not bad. How much does it cost? Wu Haoxuan asked.

"Young Marshal, according to our budget, the cost of each 'Squid-class' submarine is about 1.2 million oceans." Wei Han replied.

Wu Haoxuan nodded, such a price. It's not expensive, it's much cheaper than a 'Class A' destroyer.

"So be it." Squid-class submarines, let's build 12 first. We aim to build it all by the end of next year. At the same time, the training of submariners should also be strengthened, and it is necessary to form combat effectiveness as soon as possible. Wu Haoxuan said. By about 1910, he estimated, little Japan would probably be ready for war. Even if the situation in China changes drastically. Little Japan will also go to war in advance. It is necessary to equip these submarines in advance and form combat effectiveness.

"Yes, young marshal!" Wei Han nodded. As a navy, they can also feel that the pace of war is getting closer and closer.

"Also. The design of submarines of the next class is also not able to be put down. We need submarines with better performance. In the future, submarines will become our most important combat force! Wu Haoxuan said solemnly.

Wei Han nodded again and again, he also felt that Wu Haoxuan attached great importance to the weapon of submarines.

In addition to submarines, there are the first warships that the Northern Navy will build on its own. With the capacity of the current shipyards, in addition to building some gunboats, it is only possible to build small warships with a displacement of less than two thousand tons. So, the shipyard came up with a plan to build a first-class destroyer.

This destroyer was named the 'B-class' destroyer. The 'B-class' destroyer, with a displacement of 1,800 tons, was armed with two twin 105-mm rapid-fire guns, one in the front and one in the forerunner, four 88-mm rapid-fire guns and four 37-mm rapid-fire guns on each side. Four 533-mm torpedo tubes. The maximum speed is 33 knots (the maximum speed of 35 knots was achieved during sea trials), and the cruising range is 6,000 nautical miles at 10 knots. The 'B-class' destroyer, which can be regarded as an upgrade of the 'A-class' destroyer, has a displacement of more than 300 tons, weapons and eight 88-mm rapid-fire guns. At the same time, the number of torpedo tubes was increased to four, and the caliber of the fired torpedoes was increased to 533 mm.

The 1,800-ton destroyer is definitely the destroyer with the largest tonnage among the navies of various countries. The tonnage of the light cruisers of many countries is not much larger than this. Of course, in terms of armament, the armament of the 'B-class' destroyers is not very strong, and the most lethal weapons are the four 533-mm heavy torpedoes. If you can approach an enemy ship at high speed with a speed of up to 33 knots, and then release a torpedo, it will be extremely lethal even against a battleship. If you are fighting at night, the advantage will be even more obvious.

In future naval battles, these destroyers will play the role of high-speed killers, taking advantage of the darkness and high speed to approach the target and then carry out torpedo attacks. After the blow, evacuate immediately, and then look for an opportunity again.

The main tonnage of the destroyers of the Chinese Navy in the future is probably like this. Of course, in the future, it may be possible to strengthen the capabilities of these destroyers in terms of air defense and anti-submarine defense, to target enemy submarines, aircraft, and so on.

In addition, the cost of the 'B-class' destroyer is only 1.6 million oceans, and when converted into marks, it is only 3.2 million marks. Compared with the price of the 'Class A' destroyers offered by the Germans, it was 300,000 marks lower. Of course, this is a comparison of the cost and the selling price. If the 'B-class' destroyer is sold to the outside world, the price will definitely rise a lot. The Germans sold the destroyers of the 'Class A', naturally, to make money.

"Class B' destroyers, build four first, and gradually accumulate experience. How much more to build in the future, let's see the situation when the time comes! Wu Haoxuan said.

"Yes, young marshal!" Wei Han nodded.

Although it was only the construction of four 'B-class' destroyers, it also gave him hope for the revival of the Chinese navy. After the First Sino-Japanese Naval War, China's shipyards were nothing more than building civilian ships. The Navy has not purchased warships for more than a decade. Now, the Northern Navy is not only buying warships from abroad on a large scale, but also gradually starting to build warships on its own. The road to the rejuvenation of the Chinese Navy will begin here.

After returning to Shengjing from Lushun, Wu Haoxuan received a telegram from the General Staff Headquarters. After reading the telegram, Wu Haoxuan's face suddenly became a little ugly. Originally, he thought that after everything was on track, he could breathe a sigh of relief. But now trouble is coming at you again.

"Someone, bring in the secretary general, the director of the Military Intelligence Bureau, Director Zhan of the Department of Communications, and Minister Ma of the Logistics Department." Wu Haoxuan ordered.

"Yes, young marshal!" Zhao Hu nodded, and immediately sent someone to provoke him.

The telegram that Wu Haoxuan just read was jointly sent by Sun Liechen, governor of Mongolian Province, and Wang Liangchen, commander of the 6th Cavalry Brigade. In the telegram, they claimed that the situation in Cullen was tense. The Mongol princes and lamas, who have been constantly provoking the garrison and the provincial government staff recently, have also been affected by the local Han Chinese. They speculate that the Russians are fueling the flames. Without the support of the Russians, those Mongol princes and lamas would never have had the courage to do so.

Obviously, as the northern government tightened its grip on Mongolia, which threatened the interests of the Mongol princes and lamas, the Russians did not want to see the northern government take control of Mongolia, so they accelerated their operations in Mongolia. This also means that the Northern Army and the Russians in Mongolia are very likely to clash and even turn into a war.

Soon, Yang Du, Chen Xudong, Zhan Tianyou and Ma Zihui arrived.

"This is a telegram from the Mongolian provincial side, you should all take a look!" Wu Haoxuan handed the telegram to everyone.

After several people circulated the telegram, their faces also became solemn. Lao Maozi's ambition for Mongolia and the Northeast can be said to be Sima Zhao's heart, which is well known to passers-by. The Russian tsar was even more bent on turning northern China into yellow Russia. Although, the situation of the Russians now does not seem to be good. However, they don't seem to care about that much. That's why I jumped out impatiently.

"Young marshal, this must be the Russians stirring up trouble behind their backs, otherwise, those Mongolian princes and lamas would not have such boldness. If we choose a tough attitude, it means that we are very likely to tear up our faces with Lao Maozi, and we must think about what the consequences will be. Yang Du said solemnly.

Wu Haoxuan nodded: "I know." However, we can't back down. If we compromise and back down, we'll only give them an inch. This is just a temptation by the Russians, and if we compromise, they will be even more unscrupulous. Perhaps, they will soon send troops to Mongolia! (To be continued......)
