The historical secret of the world's first submarine

Looking at the current generations of nuclear submarines, few people know that the construction of the first submarine has encountered many difficulties and obstacles. So far, its history, attached to the New York siege, has just been published .

History of the world submarine

The first submarine looks . the egg and only one operator!

The first combat submarine in the world was born in the United States in the XVIII century, during which time it was occupied by British forces.

In the summer of 1775, the British Navy blocked New York Bay very tightly. All the way in and out of the port were sealed by British warships.

Several times, Americans sought to break the siege. In the late, dark nights, the Americans secretly used some small ships and motorboats across the sea but failed. These ships or boats were either sunk or captured by British forces. The supply and trade with outside of New York port at that time was difficult, and it became even more difficult .

Right at the most difficult times, maritime engineer David Busnell - an outstanding student who just graduated from Ielsk University has come up with the idea of ​​building a special ship. The ship could go under the water, secretly carrying landmines and sinking the great ships of the British Navy, freeing the city.

The idea is just an idea anyway. In fact, when it comes to designing and manufacturing, there are many more complicated and difficult problems.

At that time, when science and technology technology had not developed, the construction of submarines met a series of great troubles. The first is how to build thick, tight steel hulls, withstand high pressure. Next, the ship must dive, float and swim underground. The balance of the ship must be resolved when operating under the water, ensuring enough oxygen for the combat crew, determining the right direction when moving, detecting the target, determining the exact location and bearing mines attached to targets, mine timetables exploded and secretly and safely retreated before mines exploded .

The construction of the first combat submarine was very secretive and strictly guarded at Seibruk, Connecticut.

Despite many difficulties, but in a short time, Busnell and his younger brother, also an excellent maritime engineer, successfully solved a series of tough technical problems.

By the spring of 1776 , the world's first combat submarine was born. It has a picture . an egg. High: 2 meters. Wide diameter: 0.9 meters. Fighters only have . 1 person. The sole staff concurrently performs all tasks and functions: Captain, train driver, navigator, mechanic and sailor fighting.

But it took a few more tests and perfection, this submarine was considered to be able to use and execute combat missions. The submarine was secretly transported by road from the state of Connecticut to New York.

The first battle on the submarine

On the night of September 6, 1776, US Navy Sergeant Izra Lee - a courageous and courageous Marine, from Connecticut, received a very special mission: Control the first submarine to carry mines, attacking British Navy warships anchored off New York Bay.

Lee controlled the submarine secretly to reach the target of a large, bulky British warship. However, he did not succeed in the next action: The steel plate was too hard and thick to prevent it from carrying out the drill hole to mount the mine.

Even so, Lee was not confused and frustrated. After a few emergencies to get more oxygen, he let the submarine dive to continue . drilling British warships!

After many ups and downs and excessive activity, Lee was so tired and exhausted that he no longer paid attention to keeping the secret secret. Lee's submarine floated up, exposing one-third, right next to the British warship.

Submarines are one of the most mysterious and formidable weapons of attack, regardless of the weather and climate.(Photo: ticketsofrussia)
