Throughout the world, the international situation is changing, especially during the epidemic, the situation abroad is very tense. The epidemic is a war without smoke, which can inadvertently change the lives of the country and many people. This can't help but remind people of the Second World War, which changed human history.

In World War II, the fascist alliance committed numerous crimes, and the three axis countries once became public enemies of mankind. Among them, Nazi Germany made waves on many battlefields, causing incalculable and indescribable losses. After the war, Nazi Germany confessed to surrender, but left a big mystery to the world, that is, the crazy product "Manta submarine", whose whereabouts are still unknown.

In fact, the legendary submarine weapon. For Nazi Germany at that time, it was the last resistance, trying to use all his strength to create the ultimate killer to turn the situation around. At the beginning of World War II, Nazi Germany's fighting capacity was terrible and it was invincible on the battlefield. The armies of any other country are fighting in front of it. Especially their submarine forces, almost exist in the world. Research shows that Nazi Germany's military strength and scientific and technological strength at that time far exceeded that of other countries at the same time for at least 50 years, making it a unique world.

However, this hegemony was inadvertently threatened. The Italian army and the British army have successively invested in new weapons "man-controlled torpedo" and X boat, which are extremely destructive and invincible in naval battles, and there is no weapon to compete with them. Under this stimulus, Nazi Germany felt the crisis. In order to be invincible, the military began to invest a lot of manpower and material resources in submarines. First of all, the military invented a miniature submarine with a maximum load of only two people. The main goal is to land on the fleet. However, after this mini submarine was put into the battlefield, the combat effect disappointed the military. Not only can't hit the opponent, but the submarine sent can be said to be gone forever.

1943, the naval battle strength of Nazi Germany declined gradually, and the submarine forces that once depended on it were completely helpless under the attack of the three-dimensional anti-submarine network in the air and sea. Hegemony was in jeopardy, maritime operations were defeated, and Nazi Germany fell into madness and extremes, so their development of submarine combat power entered an unprecedented fanaticism. Under this fanaticism, the "Manta Submarine" was born, which was the last crazy and extreme product of Nazi Germany.

194 1 year, during the Nazi German navy's hegemony, a VS-6 hydrofoil was experimentally invented. The unique hydrofoil design makes the whole hull float on the water at high speed, with reduced resistance and a speed of 47 knots. However, although the sailing speed is extremely high, this technology has not been widely used.

1944, Nazi Germany invented the "manta ray submarine" and put the hydrofoil design into use on the submarine. Submarines of this design can sail faster than hydrofoils. Its surface speed is as high as 50 knots, and its underwater speed is also 30 knots.

In addition, the hull design of "Manta Submarine" is also very special. The center of the hull is covered with plexiglass to isolate it from the outside world, so as to carry the crew, and 440 kW motors are loaded on both sides. What is more unique is that the designer installed wheels on the submarine, which realized the independent separation of the submarine and the hull, and even went ashore to fight.

The design of trimaran and the installation of wheels are pioneers of world military affairs.

Although it is a submarine, the "Manta Submarine" is the most pocket-sized submarine weapon. The total length of the hull is only15m and the width is only 6m. Without any load, it only weighs 15 tons, and the maximum weight after full load is 50 tons. Although it is a "pocket mini-submarine", it is well-equipped, and only 800 horsepower Walter diesel turbines are installed, which ensures the ultra-high speed on water and underwater.

In addition, one thing is the most advanced and attractive. Nearly 100 years ago, in the middle of last century, Nazi Germany actually tried to install "underwater anaerobic propulsion device" on "Manta submarine", which is the unique AIP device of modern submarines.

AIP device is a modern and widely popularized design, which was first discovered by Germany in the last century. Its researcher is Hellmers Walter, an engineer who is famous for developing submarine engines. As an expert in submarine research, Walter has been working hard to develop new submarine designs for anaerobic propulsion under water. And in 1925, he applied for a patent for this basic idea.

Walter's propulsion device abandons the traditional inefficient and bulky battery and engine, decomposes hydrogen peroxide to generate steam, and can drive the turbine and propeller without the intervention of outside air, so the submarine is extremely airtight, so it is also called closed cycle engine.

Although the blueprint was designed, it was not until the eve of World War II that Walter's design was taken seriously, and the military built the V-80 experimental submarine on this basis. The first test was amazing. At that time, the maximum speed of the submarine was only 8 knots, but according to Walter's design, the speed of this experimental submarine was as high as 23 knots.

Although the speed is amazing, the disadvantage is also very obvious. Obviously, the military will put it in limbo, but the security is extremely poor. Although Nazi submarine commander Deng Nici once adopted this design and launched the 17th submarine, it ran aground again due to poor safety and huge energy consumption. This time, the Nazis re-adopted the closed-cycle engine. On the basis of the XVII submarine, two motors are added to ensure the endurance, which can reach 500 nautical miles.

The unique design of "Manta submarine" is not only that, but also the design on the two wings of the hull can carry torpedoes. Take 450mm torpedo as an example, it can carry as many as 8 pieces, and TMB mine can carry 12 pieces. However, this design also has disadvantages. The carrying and installation of torpedoes and mines have great influence on the performance of submarines.

Although there are all kinds of pioneering designs leading the world, "Manta Submarine" has not left more ink marks in the history of war, only design concepts and experiments. It is generally believed that Nazi Germany was defeated when the German army tried to produce, and all the relevant documents about the "Manta submarine" were destroyed, leaving only one model for history and the world.

"Manta submarine" is a mystery, but its design concept and performance are still very advanced. No matter the design of three-body or the application of hydrofoil device and AIP device, although it seemed too strange at that time, even after 100 years, they were still not backward.

However, although its status and significance are transcendent, the era that should have belonged to it has passed. After nearly 100 years of development and progress, although some system designs have been retained, the new technologies and designs produced by innovation and development are no longer comparable to those of "Manta submarine".
