About Underwater Submarine and Attacker Submarine

Underwater submarine

Underwater submarine is able to move under water and freely floating vessels. Usually there are many crew stays in the submarine. The submarine is often described as a boat by comparing it with its different shapes and vessels. Submersible submarine has been built since many years and in the nineteenth century its use in the navy of the country was inevitable.

Use

The generality of the use of submarine in the First World War is widely observed. At present, many large-size navies have a lot of collections. It has a broader role in counterattacking enemy ships or submarine attacks. Also, the effectiveness of the submarine ship fleet, the removal of the block, the operation of the submergence of the conventional ground attack and the special forces are secretly maintained.

Usually the submarine is used. Among them, submarine is also used for sea science, rescue operations, thorough investigation activities, inspection and maintenance facilities. Also, in connection with the search and rescue operation as well as the activities of the submarine, it is also included in the cable repair in Sagarele. Submarine submarines are used to inspect the submerged archeology to attract tourists.

Infrastructure

Most large submarines are made of tube-shaped structures. The interior has communication facilities and perisak control. This is the name used by the modern submarine to be called the United States Sail or Pala and Europe in Finland. The early submarine was used for running and observing the tower, or from which the main structure was used to open the main structure by pressing the small pyroscope. The propeller or pump jet is on the back, and the balance between the control of many types of fluid substances is controlled. But in small, floating in deep water and special type of submarine, this can be different from the structure of this type.

One of the most sized vessels in vessels with very large capacity. One to two people can be managed for a short time; In the same way, it is possible to stay for six months under water. Russian typhoon class submarine has been considered as the world's largest submarine today.

History

The first waterborne submarine built by the Cornellius Jacquesben Drebail
In 1620 Cornelius Jacquesben Drebil was known to have discovered the submarine as the first naval ship by a Dutch.He was working in the Royal Navy under King James I of England. He invented a submarine machine funding the concept and structure introduced by English mathematician William Bourne in 1578. His inventive submarine has been known as the Drebelian submarine. The machine had to be dragged to the front. There is some debate about the invention of such submarine. Some claim that it was dragged by another boat. Later, two more advanced versions were examined in the River Thames between 1620 and 1624. Everyone was bigger than the previous.

The 3rd and the latest version of Sabadojaj had 6 straits and 16 passengers were able to carry. This model was made under the direction of King James I. And thousands of Londoners visited it. The submarine was able to stay submerged in three hours of water. The submarine was able to stay below the water from 12 to 15 feet (4 to 5 meters), with the ability to move from Westminster to Greenwich. Draubel, King James, requested the submarine for a pilot movement. The king agreed on his request. As a submarine submarine under the water of Tomes, the first traveler is involved in the screen of history as king.Subsequently, submarine was examined several times in the River Thames. But it was not able to attract enough attention from any person on the Navy. It has never been introduced in the battlefield.

In 2000, two sailing submarines were built by William Bourne, introducing ideas and designs. Mark Edwards made it for the documentary titled Building the Impossible entitled BBC Television Program. It was successfully operated in Dornie Lake, located in Atten area of ​​Berkshire.

Usage Facilities

Experts are aware of its military usefulness shortly after the submarine was discovered as the first navigable water. About the strategic advantages of submarine, Bishop John Wilkins of Chester area in England, in 1648, presented the mathematical magic texts -

Personally, one person is able to make an invisible presence in the coastal areas of the world. That's why he will not need the discovery of the waterways or the defense system when traveling to Saddaujjh.
Do not have to deal with sudden and uncertain currents and severe storms as safe vehicles. Because it is impossible to raise the submarine up to five or six piers or a few feet in the sea or fifteen feet below. Apart from the pirates and robbers; Its role in self-defense is also remarkable from ice and frozen snow.
It carries a wide variety of advantages against naval enemies by staying in the water and attacking casually.
It can be used as a means of supplying food or supplies invisibly in the direction of naval blockade.
Its benefits are inexplicable and comprehensive in Sambharan's examination.

Attacker Submarine

An attacker submarine or predator-killer submarine, a submarine designed specifically for attacking specially designed submarines, surface fighters and commercial ships. In the Soviet and Russian navy, they were called "multi-purpose submarines." They are used to protect friendly surface battlefields and missile submarines. Some attacks subscribe are equipped with cruise missiles that are mounted in vertical launch tubes, to include land targets. Their chance of potential operations increased.

Attack submarines may also be driven by nuclear-powered or diesel-electric ("conventional"). In the United States naval naming convention, and the equivalent NATO system (STANAG 1166), nuclear submarine attack was known as the SSN and their diesel-electric predecessor SSKs. In the US Navy, SSNs are known as "rapid attack" unfficially.

Origin

On February 9, 1945, both HMS Venturer and U-864 were deep in water. This was the first submarine submarine by a submarine submarine and until now there was only deliberate dive. U-864 was snorkeling, thus creating a lot of noise to detect the vector's hydrophon (an initial form of passive gold) and was lucky in 45 minutes for the Venture's brain to navigate the U-boat. Venturer's Commander, James S. "Jimi" Londurs, it was chocky in running a U-boat expedition during an "emergency deep" tactic, thus hearing the torpedoes in the water, thus the "spade" of the four torpedoes immediately found that the guess is targeted . A hit, and the U-Board drown.

Following World War II, especially the type XXI U-Boat has improved German submarines, the allies, especially the US Navy and the [[Soviet navy]]]. Initially, type XVII U-boat, a Walter hydrogen peroxide - fueled gas turbine, allows higher water intensities, it was considered to be more advanced than actually. The case, and was immediately considered as a future submarine technology. However, with a high battery capacity for type XXI, streamlined and high drift speed, fully developed and became the basis for most non-nuclear submarine designs worldwide through the 1950's. [3] In the US Navy, World War II submarine like the XXI of the Greater Climate Initiative Power Program (GPPY) was created for modernization.

It is realized that the Soviet Union has collected Type XXI and other advanced U-boats and will soon set up their own equivalents. In 1948, the US Navy determined the number of anti-submarine warfare (ASW) -contactable submarines, to deal with hundreds of advanced Soviet submarines, which was expected to be by the 1960s. Two examples were considered: a possible visible presence of Soviet forces existed to create around 360 submarines and a "nightmare" would be visible that the Soviet Union could build a faster submarine such as the Germans made the U-boat, and it was a strong level 2, 000 construction of submarines. The projected US SSK says that in this situation, 250 first and 970 submarines are needed for the next step. Additional anti-surfaces, guided missiles and radar picker submarines are also needed. In comparison, at the end of World War II, except for submarine training of the US embassy, ​​there were only 200 vessels in total submarines.

USS K3 (SSK-3) VQ-4 gold dome

A small submarine suitable for mass production was designed to meet the requirement of SSK. It is a K-1 class three submarine or later known as the Barakuda class, which served in 1951. They were much smaller than the 750 tonnes (760 tonnes) submarine weighing 1,650 tons (1,680) of the boat produced in World War II, they were equipped with an improved passive gold, Dhanukmakya VQUR-4, but there were just four torpedo tubes. Initially, a golden name around the Cunning Towers is considered, but the tests showed that low mounting gold was very less affected by Sun-room's own noise. During the development of objective-based SSKs, World War II submarines were considered for transformation into SSKs. The low-capable Gouto class was selected because of this, because some deep-diving bales- and tech-class boats are being upgraded to GQPVS. In 1951-53, seven GATO-class boats were transformed into SSKs. These were the golden bow of SQL-4, out of which six of the torpedo tubes made space for four gold and its electronics. Four star torpedo tubes were kept. Two diesel engines were removed, and the auxiliary equipment were installed in their place and the words were disconnected to reduce the subarmine's own words.

Soviet quantity takes longer than expected to start production of new submarines. By the year 1922, only ten had entered the service. However, the production started soon. At the end of 1960, a total of 320 new Soviet submarines were created (very close to the 1948's low-end concept of the USNN), among them 215 projects, 613 class (NATO Hoskie class), a small version of type XXI. Significantly, eight new submarines were nuclear power.
