Seeking the performance of the submarines of Germany, the United States, Japan and Britain 30

German submarines are the best, do not explain.

The first is the improper operation of the submarine crew, which led to the failure of the French and British nuclear submarines with advanced detection technology to detect each other. The "Avant-garde" and "Triumph" that collided this time were both put into service in the 90s of the last century, and they are very advanced in terms of power, ** and communication observation systems. In terms of detection technology, in addition to being equipped with common underwater acoustic navigation systems, these two types of ships theoretically also carry towed line array sonar with a large detection range, and the detection technology is very advanced.

The second possibility is that France has always been very independent in defense and military, so Britain may not be very clear about the performance of French nuclear submarines, while France has always been ahead in the miniaturization, compact design and stealth and noise reduction technology of nuclear submarines, so it is not ruled out that the "avant-garde" failed to discover the "Triumph" in time.

The Anglo-French nuclear submarine collision was the first ever collision between Allied submarines. Generally speaking, the probability of a submarine collision is relatively low, and there is no such thing as a so-called "congestion" in the ocean. The oceans cover about 70% of the Earth's total surface.

Moreover, there are only more than 100 nuclear submarines in the world, and under normal circumstances, half of them do not sail, and the two submarines will only appear in the same sea area unless they have the same mission of interest, and the probability of collision with each other is even more minimal.

Judging from the information released so far, the "Avantgarde" was towed to the Faslane base in Scotland for repairs, and the "Triumph" returned to the base on its own, which shows that the damage to the "Avant-garde" should be more serious than that of the "Triumph". However, the possibility of nuclear leakage is very small, because submarines have two layers of steel hulls, namely the outer layer of non-pressure-resistant hull and the inner layer of pressure-resistant hull, and there are one or even several layers of steel hull outside the nuclear power system. (Ding Dawei interviewed and organized).

Yes. The German U-boat is the most mysterious ** in World War II, and the sneak attack is its most terrifying tactic, so its tactics are also known as wolf pack tactics. At the beginning of 1906, the Germans built U-boats powered by diesel engines, and in 1916 and 1917, the total number of merchant ships sunk by U-boats reached 1,100 and 2,600 respectively; In World War I, German submarines sank a total of 5,906 merchant ships with a total tonnage of more than 13.2 million tons.

In World War II, Germany built a total of 1,131 submarines, plus 57 before the war, a total of 1,188 submarines, which sank 3,500 ships and killed 45,000 people; By the end of the war, 781 German submarines had been sunk by the Allies.

At the beginning of World War II, although German submarines were released after Hitler came to power, the quantity and quality were not very high. Because it is difficult for the surface ships of the German Navy to surpass Britain in a short period of time, Germany chose submarines as a breakthrough, so submarine research and development and manufacturing have been put on the priority (of course, this has nothing to do with the fact that the commander-in-chief of the German Navy is a submarine captain in World War I) The Luftwaffe and the Army actually reflect a similar situation: Germany's BF109 and FW190 are technically more advanced, but there is no decisive advantage, and the Luftwaffe relied on pilots who have been tempered to win the skies in Europe in the early days of World War II.

The German infantry and armored units, which were not even advanced in equipment (No. 3 and a few No. 4), also relied on a high degree of coordination to take almost all of Western Europe, and almost all of Eastern Europe. With the Tiger and Leopard style, the technical lead is only due to the absolute disadvantage in numbers. Hope it helps you.

After World War I, the Treaty of Versailles stipulated that Germany could not own submarines after the war. After Hitler came to power, he decided to vigorously develop the navy.

Because Germany's naval power strength could not compete with Britain and the United States, it focused on the development of naval power. It was against this background that the U-boat developed its strength.

During the Second World War, Germany built a total of 1,131 submarines, plus 57 before the war, for a total of 1,188 submarines. These submarines sank 3,500 ships and killed 45,000 people. By the end of the war, 781 German submarines had been sunk by the Allies.

The German U-boat is undoubtedly the backbone of the German Navy and the trump card of the German Navy.

The XXI submarine, a type of submarine that entered service in Germany at the end of the war, was the most advanced in World War II.

During World War II, the Nazi German Navy had Type II (Type 2), Type VII (Type 7), Type IX (Type 9), as well as XXI (Type 21) and Type XX III (Type 23).

All submarine models are named after Roman numerals, and each model also has a series of improved models, such as the IID (2D) type, which is improved from the IIA (2A) type, the VII series has VIIB (7B), VIIC (7C), VIIC 41, etc., and the IX series has IXB (9B), IXC (9C), IXC 40, etc. There are also submersible tankers XIV (nicknamed "Cows"), which are used for refueling, and X-types, which are used for minelaying.

The XXI submarine, a type of submarine that entered service in Germany at the end of the war, was the most advanced in World War II.

The maximum speed knots on the surface and the maximum speed knots under the water, because of its streamlined hull, the speed is faster than that on the water, and the current submarines are developed from this submarine.

It can dive up to 300 meters, has six torpedo tubes, cancels the tail launch tube of the previous U submarine, and has an advanced automatic torpedo loading device, so that the torpedo can be loaded in 20 seconds, carrying a total of 23 torpedoes.

Type 21, of course. However, the data on the 1st floor is pure nonsense, the number of Type 21 in service is still quite a lot, but it is a pity that its own capabilities are limited, and the number is small, and there is no chance in front of the superior anti-submarine forces of the Allies. The performance of the Type 7 mentioned on the 3rd floor is actually very average and average, but because of its large number and intensive use, it has brought the advantages of wolf pack combat to the extreme and obtained huge results.

In World War II, Germany was generally armed with U-boats. The largest number of enemy ships were sunk.

The most advanced in Germany during World War II was the "XXI" submarine.

Relying on advanced U-boats, Germany effectively attacked Allied merchant and convoy convoys in the Atlantic. Admiral Karl Dönitz, who commanded German submarines, invented the "assembly" tactic, using 6-12 submarines to form an underwater fleet, following the convoy during the day, entering the attack position at dusk, and penetrating the convoy at night to carry out a short-range attack with a direct torpedo.

The U-boat is a submarine, which was used by Germany during the First World War and the Second World War. Since the numbers of German submarines are named after the initial U plus a number in the German word "untersee-boot" (meaning "submarine", which is written literally into English as Undersea Boat, abbreviated as U-boat), such as U-47. To distinguish it from the submarines of the Central Powers (in English"submarine"), used in English"u-boat"to call the German submarine.

Chinese translates to "U-boat", which can also be abbreviated as "U-boat".

In order of modeling, they are:

Type X submarines. Type XI submarines.

XIV type submarines.

Type XVII submarines.

Type XVIII submarines.

XXI type submarines.

Type XXIII submarines.

Submarines of the XXVI type.

If you don't include those under development and planning, the most advanced ones are Type XXI Submarine, Type XXVI Submarine, Type XXVI Submarine, Type VII Submarine, Type VII Submarine, and Type VII Submarine.

Germany's most advanced U-boat in World War II sank because of a "poop", netizens: It's really wonderful.

U-134, the German ace submarine, once stormed Scapa Bay and sank the battleship Royal Oak.

21 large submarines are XXI, 23 small submarines are XXIII, AIP does not rely on air propulsion submarines are XVII equipped with the Walter system ,,, the above three.

There are more than 200 submarines in return, about 100 answers, and 4 have been built. However, because the operation is different from the old submarine VII and IX, although there are many equipment, there are not many that can have combat effectiveness... The last two German submarines sunk in World War II were sunk by XXIII.

Type 21 submarines, but the best record is still Type 7.

U-715, there is a film called "Hunting U-715".

A submarine, a submarine.

<> "This German submarine is also too well made!"

The Type 212 submarine is a type of conventionally powered attack submarine under the German Navy and the Italian Navy.

This class of submarine is designed and built by Germany, is the crystallization of Germany's excellent shipbuilding technology and the most cutting-edge technology, and is also the world's first AIP submarine using fuel cells, under the careful design of the German shipbuilding industry, the hull of the 212 type has the best aspect ratio, and the hull line is more streamlined than all submarines previously designed by Germany. We can also see from the diagram that there are almost no gaps, and they are perfectly connected to each other.

The Type 212 submarine is also the only submarine in service in the world today that is equipped with a fixed gun, and its Muraena automatic artillery system allows the floating submarine to have a certain degree of close suppression of fire when the submarine performs some special tasks on the surface of the water, or when facing an unexpected situation.

The Type 212 submarine is a cigar-shaped submarine with a single-hull and double-hull hull structure, with a single-hull structure at the front and a double-hull structure at the rear to accommodate fuel cell hydrogen storage containers. The stern of the ship is pointed in the shape of a cone, and the enclosure of the command station also has an excellent streamlined shape and a sloping design at the front, which can effectively reduce the drag when sailing. So the overall look of the 212 is very smooth and streamlined.

The Type 212 is the first submarine in the world to use a fuel cell-diesel-electric power system. The fuel cell of the U-31, the lead ship of the Type 212, is Siemens' first generation of practical PEM fuel cells, which is composed of 9 PEM fuel cell units, two 14-ton liquid oxygen storage tanks and hydrogen storage containers, each PEM unit can output 34KW, and the total power of the nine PEM groups is 306KW, enabling the U-31 to dive underwater continuously for two to three weeks at a low speed of less than 5 knots.

The 212 has a floating displacement of about 1,500 tons, a submersible displacement of about 1,830 tons, and a diving depth of more than 200 meters. Top speed 20 knots on water, speed 12 knots on the surface, 20 knots underwater, endurance on the water: 8000 nautical miles 8 knots, underwater:

420 nautical miles 8 knots with a crew of 27 people.

The main armament of the Type 212 is 6 533mm torpedo launchers, with a torpedo load of 24 pieces, using STN Atlas Elektronik DM-2A4 torpedoes, which can be attached to the external mine deployment box, IDAS submarine-launched anti-aircraft missile system, Muraena automatic artillery system, etc.

In addition to the Type 212, Germany also launched the Type 214 submarine in 1997 in the late 90s with the technology of the Type 212A and the elastic concept of the Type 209, replacing the Type 209 as the new main force of the German submarine industry in the international market. The Type 214 has a similar streamlined hull to the Type 212A, the same advanced equipment, a further increased displacement, and a fuel cell system with a greater range. Although it was once on the verge of cancellation, the Type 212A, which combines the most advanced technology of the new generation of traditional power submarines, has finally turned the danger into a disaster and has become the inheritor of Germany's excellent submarine pedigree.

<> "The world's best-selling German "214" class conventional submarine.

The Type 214 conventional submarine is a conventionally powered submarine developed by Germany, which is an export submarine developed based on the German Navy's Type 212 submarine. The Type 214 submarine follows the streamlined hull of the Type 212 submarine and the Type 212A submarine, with improved equipment, a further increase in displacement, and the use of a fuel cell AIP system with a greater endurance.

The construction of the first submarine of the Type 214 submarine began on January 16, 2001 at the Hardway Shipyard in Germany, was named on April 22, 2004, and delivered on September 30, 2005, and has been given to Greece, South Korea, Portugal and Turkey. Due to the use of modern equipment and high-performance AIP systems for the Type 214 submarines, the submarines have good concealment.

The Type 214" submarine adopts modular design and construction technology, which closely integrates the best systems, sensors and submarine platform into one, and is suitable for completing various missions. The adoption of all new technologies, new processes, and new design concepts have greatly improved the performance of the "214" submarine in different aspects, raised the submarine's diving depth and diving time to a new height, and reduced the submarine's acoustic, thermal, and magnetic characteristics to a minimum.

Regardless of the one-way performance index or the comprehensive index, the "214" submarine represents the technological development level of conventionally powered submarines.

Equipment Profile. In order to make up for the gap in the market, the old German shipyard Hardway Shipyard (HDW) based on the 212 212A submarine, adopted the design concept of the Type 209 submarine, integrated the innovative AIP technology of the German Type 212A submarine, and developed a simplified version of the Type 212A submarine, that is, the Type 214 submarine, which is specially designed for export. In terms of conventionally powered submarines alone, the Type 214 submarine is the best submarine of its type.

At present, it has been exported to Greece, South Korea, Portugal and Turkey and other countries.
