The beginning of the 20th century was an era of technological leaps, in this era, human beings really expanded their range of activities to the sky and underwater, the success of airplanes and the increasing maturity of submarine technology made the scope of human activities have been greatly extended, and the crystallization of these human science and technology was used in killing for the first time. As early as the Russo-Japanese War, both Japan and Russia had already ordered submarines, but they were not put into service, and the use of airships in the war did not begin until the First World War. The bombing of the German Zeppelin made the British very annoying, and the reconnaissance airship that was lost to the high seas fleet also made the Germans' reconnaissance means much higher than that of the other side, of course, because the weather in the North Sea was really bad, so the role of the airship reconnaissance was much lower.

And Xu Jie, as a traverser, in terms of strengthening the Huaxia military, in addition to increasing conventional troops and equipment, these advanced high-tech gadgets must also attract great attention, after all, the advantages brought by this thing in reconnaissance are too obvious! In terms of airships, if nothing else, in 1900 a German named Zeppelin would produce the first truly large rigid airship. And this will usher in a new era!

In 1900, Count Zeppelin, who was a lieutenant general in the German Army, built the world's first all-hard airship, which was called LZ1 with an aluminum skeleton and a length of 129 meters and a diameter of 11.6 meters. The entire skeleton consists of a longitudinal keel and 24 wooden bridge strips and a large number of longitudinal and transverse wooden strips. There is a tarp on the outside of the frame. The whole airship consists of two cabins, which are equipped with a 16 hp diesel engine. Buoyancy is provided by 16 airbags. With a total volume of 22,500 cubic meters, it provides 13 tons of buoyancy and a load capacity of 8,700 kilograms.

The first airship could already be used for long-term reconnaissance at sea or on land. As the saying goes, stand tall and see far. After forcibly seizing the superiority in high altitude, the Chinese army can have better battlefield perception. In the future war against Russia. Whether it is the vast Northeast region or the South China Sea, the battlefield is wider than any other war in the past world. An army of tens of thousands is not obvious at all in such a vast area, and coupled with the terrain and enemy interference, the land reconnaissance capability will be greatly reduced, and even if the opponent's whereabouts are discovered. There is also a lack of communication equipment that makes it impossible to transmit information quickly, resulting in delays in information. So much so that the fighter plane was delayed.

But it's not the same if there is an airship, which is not just a reconnaissance unit. It is also an information transmission center. The radio equipped on it can greatly improve the efficiency of information transmission, and compared with ground reconnaissance, the airship also has a major advantage, that is, it can repeatedly reconnoiter in the target area for a long time. And it's extremely secure. At least at the same time in history, nothing could threaten an airship, except in the event of a raging storm, of course!

And in the vast South China Sea. Although it is not realistic to let the airship go directly to the Dutch East Indies for reconnaissance. But at least coastal surveillance can be guaranteed, if Huaxia can get outposts from the Philippines or British Malaya, then the Russian fleet operating in the direction of the South China Sea will certainly be under the supervision of the Huaxia fleet, of course, the number of airships must be sufficient, in addition to the search area is too large, the relay transmission of information is also a problem, after all, the radio at that time was calculated on a 100-kilometer level. A message to send back. It is absolutely not possible to do without the help of a radio-equipped sentinel ship or airship. However, it is better than relying solely on ship searches, especially in the face of war. With the help of airships, the side will definitely be able to grasp the dynamics of the fleets of the two sides in more detail, so as to know themselves and the other.

If the role of the airship is limited to reconnaissance, then the role of the submarine is too great, in fact, in 1900, a successful submarine had all the skills needed, but people at that time did not know how to use these things on submarines. As early as 1893, the Turkish Navy already had a submarine of more than 260 tons, which is not small in terms of tonnage, but this submarine used a steam engine, and in later years, Horan built a successful combat submarine, this little guy of less than 50 feet can carry 5 people and has a torpedo tube, powered by a gasoline engine, with a water speed of 7 knots and a range of more than 1,000 nautical miles, an underwater speed of 5 knots, and a battery power range of 50 nautical miles. And in 1900, the French had already produced double-hulled submarines, armed with specialized submarine-launched torpedoes.

It can be said that the current submarine is only one step away from success, and this is the application of diesel engines! As long as the diesel engine is equipped, there is no essential difference between the submarine at this time and the submarine of the 1 war (the first U-boat was accepted by the German Navy in 1906), the diesel engine is powered, the battery provides underwater navigation power, equipped with a new type of thermodynamic torpedo equipped with gyroscopes, and with the high-quality periscope produced by Zeiss, it can be said that as long as it is properly designed, it is not impossible to make a batch of original U-boats. If the ship type is optimized, it is not impossible to carry out tasks in the South China Sea.

And in the era when there was no sonar, the only ones that could be used for anti-submarine were those unreliable hydrophones, and by the way, those depth charges that broke down frequently! In Xu Jie's plan, Xu Jie needs to rely on Germany's outstanding diesel engine and new periscope to arm this shark that has not yet grown!

The tonnage of the new submarine must reach 400 to 500 tons, so that it can have enough endurance to reach the other side of the South China Sea to carry out combat missions. AT THE SAME TIME, IT SHOULD ALSO BE EQUIPPED WITH A NEW TYPE OF HIGH-POWER TORPEDOES WITH A CALIBER OF 500 MM OR MORE. There must be at least 4 or more launch tubes, after all, it is very difficult to load the torpedo, plus the submarine is too slow, basically there is no chance to attack after a round, and the number of torpedo tubes directly determines the strike efficiency of the submarine. In addition, the submarine should be equipped with a radio, and although it is not intended to be used to communicate with headquarters, it can at least keep the submarines in contact with each other to a certain extent.

In those days, there was no radio sideways technique, so there was no need to worry about using radio to expose your whereabouts. At the same time, data can be shared, and if the Russians really want to use the Dutch ports, then all Dutch and Russian transport ships that appear in the South China Sea will be targeted. By the way, it's best to bring a little mine, if the submarine carries mines to carry out offensive mines on local ports, this is a very good idea, thinking that the other party hit a mine at home, Xu Jie couldn't help laughing.

In short, the material conditions for submarine warfare have been met, and now Xu Jie needs to seriously formulate a system, a submarine warfare system suitable for the current situation. At the same time as implementing submarine warfare against the Russians, Xu Jie also needs to develop a complete anti-submarine system to deal with the submarine sabotage warfare that the Russians may take, although the Russians have submarines in history and have not entered the battle, but now the situation has changed, Xu Jie does not dare to bet!
