Submarines can run on the surface of water and under water and is a military submarine. By definition, ships carry long guns and other weapons used in war by the fleet. Ships throughout history have tried to build submarines and fast and sink under water.
A submarine is a difficult location from the surface allowing it to move close to attack enemy ships. It also allows submarines to run around without being seen.
Early subs Each boat was named pig by the sailors, because the air inside was old and rotten.
The United Navy has built and commissioned many different types of submarines and named them after the Navy. states and magnates. American Naval Subs are classified according to their designs or types of engines and each class is named after the first ship in the circle.
Many submarines have a long, cigar-shaped hull (underbody) and military submarines have two hulls where one fits inside the other. The stern of the submarine is equipped with a stream so that it can easily travel through the water.
It also excludes submarines. These are doors that seal tightly to keep out water. Military sailors look to use submarines as lookouts when it is below the surface, as military submarines do not have windows.
To see what is happening on the surface when submerged, sailors use periscopes and sonar. Sound waves use sounds to measure depth and locate aquatic objects.
On top of most submarines is a conning tower, which is called a conning tower. This tower has two vents through which air enters and smoke or smoke escapes. The vent through which the air enters is called the vent and the vent that allows the smoke and fumes to escape is called the exhaust. The condensing tower also contains submarine periscopes and radar antennas.
Military submarines usually have two decks where the crew live and work with the most important control room. cell of the ship
Sailors sink the submarine to add traction and reduce ballast to help it rise. All this is done by opening and closing valves in the ballast tank.
Submarines use taxicab planes to help steer them. The diving plane is a metal plate that tilts up and down and is located at the bow and stern of the seat. Submarines also have rudders, which help them steer left and right under the water. Many military submarines have powerful engines and battery-powered electric motors.
Some modern submarines have nuclear powered engines that last longer than other types of energy. Nuclear power comes in the form of sticks.
The speed of submarines is measured in knots. One knot is 1.15 miles per hour. The fastest class of subs have a top speed of 50 knots, which is about 58 miles per hour. By the 1950s, better streamlining and engine design enabled submarines to travel faster underwater distances.
The submarine’s most widely used weapons are its torpedoes and today, subs still carry better types of torpedoes. They also had ant guns attached to their towers. Since the 1950s guided missiles have been the largest weapons in the sub. These missiles are guided by radar to their target and some of these missiles can range up to eight miles.
Submarines have been around for a long time and the first submarine was made by Cornelius Drebbel in 1620. The submarine was a twelve person boat covered with oil skin (wetting leather with oil to make it waterproof). The crew rowed the submarine, but Drebbel’s submarine could not move too fast or too deep.
Inventor David Bushnell built the first military submarine in 1775 and named it the Turtle. It was made of wood, and shaped like an egg. The turtle couldn’t hold one sailor and couldn’t get high. Bushnell built a submarine to help colonists fight the British during the Revolutionary War of 1775-1783.
It was the first submarine sunk in Civil War 1861-1865. In 1864, a Confederate submarine called the Hunley sank Union warships.
In 1898, another inventor, John Holland, built the first submarine that had gasoline engines and batteries. This under the name Holland after the inventor. In 1900 the fleet was bought in Holland, where the Navy made it the first submarine. Unfortunately, the smoke of Holland, which he suffocated and often confused with poison.
In World War 1 (1914-1918) the German Navy became the first Navy to use diesel. -powered battle submarines. These boats were called U-boats and in 1914 a U-boat sank three British longships.
Although the US Navy did not use submarines much in the First World War they were impressed by how well the U-boats worked and through built and tested many submarines for the entire US Navy in the 1930s. These all had diesel engines and electric engines.
During World War II US Navy submarines assisted in the battles with Japan. 300 US submarines were used in this war and 1,178 Japanese ships were sunk and 214 Japanese long ships. Only 52 US submarines were destroyed.
After World- War II US The Navy wanted new submarines and sold many of its old partners. The fleet then surrounded the ships with their deck guns and anti-aircraft guns. This had a positive effect on the speed of the submarine and since 1954 the fleet has installed nuclear weapons on its submarines which allow to concentrate supplies deeper and refueling less frequently.
Nuclear powered submarines could dive as deep as 2,300 feet and many modern submarines can stay submerged for months, only needing to refuel every 15 years.
Since the 1960s the Navy has been building new types of armored missiles with each new fleet being larger and more powerful. The fleet also attacked submarines that engaged in battle with enemy submarines. These submarines are armed with torpedoes and short-range missiles.
