Chapter 376: U-47 Submarine

The German navy is moving towards the oceanic navy, battleships, aircraft carriers, one after another, but Germany is not lagging behind in terms of submarines.
Dunnitz is still in charge of the submarines of the German Navy. Under his leadership, the performance of German submarines is constantly improving, and the type VIIB submarine is now under construction.
The submarine force of the German Navy has a long history. Although the submarine was castrated after the First World War, new submarines are constantly being built as they gradually get rid of the restrictions of the Versailles Treaty.
The latest submarine has lengthened the hull, improved the fuel tank, installed a supercharger on the diesel engine, and set the stern torpedo tube inside the pressure hull.
Through optimized design, the operational performance was improved, and the speed and endurance of the submarine were increased. A total of 24 ships were produced before and after, which was the absolute main force in the early stage of World War II.
And now, under the sea, sailing silently is one of the legendary submarines. The U-47 submarine that entered service last winter belongs to the seventh submarine unit.
The propeller at the tail was slowly turning, and the entire submarine was sailing almost in absolute silence.
Submarines in this era are very noisy. The most important way to reduce noise is to reduce speed! The propeller at the tail can be seen by the naked eye how slowly it turns. The entire submarine is traveling at a very low speed of 1 knot.
Without starting the diesel engine, the current depth is tens of meters below the sea surface, and the distance from the seabed is probably only a few meters. This is an absolutely adventurous voyage!
Only the electric motor makes a slight buzzing sound under the power of the battery.
In the submarine, it is almost dark. When the battery is working, all electricity must be saved. At the same time, almost everyone has obeyed the order to sail silently.
No one said anything.
On the bridge in the middle, Captain Prien, the bearded captain, stood in his post with a serious expression. He was not wearing a shirt and looked a little disorganized.
Once the submarine sails, if it cannot float, then a special smell will gradually condense inside the submarine. The diesel volatilized by the diesel engine and the smell of dozens of crew members will gradually condense together.
Therefore, once they go to sea, no one cares about their disfigurement. The submarine soldiers are often shirtless. After all, they are not easy underwater.
That handsome uniform should be worn when going back to the shore.
In front of Prien was the helmsman. At this time, the helmsman was also serious. They knew what a terrible place they were about to enter!
Half a month ago, they went to sea, and yesterday, they received an order to mix into Scarpa Bay tonight and wait for the scheduled attack!
For the German navy, everyone will never forget Scarpa Bay. Many people have been thinking about how to attack Scarpa Bay from the first day of becoming a navy!
Among them, Captain Prien,
Prien was just 30 years old, when he was most energetic.
Prien was born in 1908 in Osterfield, Saxony, Prussia. When he was young, life was very difficult. His biggest dream was to follow the footsteps of his hero, the Portuguese navigator Vasco da Gama.
At the age of fifteen in 1923, he began to realize this ambition in life. After several years of hard work, he became the captain.
When the great prospects waved to him, the economic crisis came.
Due to the reduction in the size of the fleet, Prien was unemployed, and Prien, who fell into despair, followed the rising Workers' Party and started his new life.
Prien first went to the light cruiser Königsberg, and then was sent to the submarine training school in Kiel for training.
During the Spanish Civil War, he conducted two patrols on the U26 submarine under the command of Captain Weiner Hartmann. Last year, he became the commander of the current submarine.
In the entire submarine, only Prien knew that his destination this time was Scarpa Bay from the moment he left the port, so he has been studying it for the past few days.
Scarpa Bay is 24 kilometers long from north to south and 13 kilometers wide from east to west. As an important port of the British Royal Navy, the defense here is not generally strict.
After all, during the First World War, the German submarine captains expected to get here to attack.
Defending submarines is also very easy. This port has 7 entrances, all of which are equipped with anti-submarine nets and minefields.
The anti-submarine nets are very simple, just like ordinary fishing nets, they are arranged underwater, so that the naval ships on the water will not be affected when they pass by. However, the submarine navigating underwater will hit one head and the propeller will be entangled on the net. , Then there is no way to return to heaven, there is no other way except to surface obediently.
At the same time ~EbookFREE.me~ the Rainbow Operation in the past few years, those German shipwrecks will also bring inconvenience to the navigation of submarines.
However, these underwater facilities have existed for many years after all, so many of the equipment has already aged.
For example, at the entrance to Kirk Strait on the east side of Scarpa Bay, that is, the wooden fence and anti-submarine nets at the seventh entrance have been in disrepair for a long time, and have lost their due function. Dropped here, ready to repair!
This is the only chance!
The body of the submarine suddenly tilted, grabbing the handrail beside him, Captain Prien's face was calm, he knew very well that the sea outside was too turbulent.
The entire Holm Strait is turbulent, and it is almost impossible for submarines to reach. Submarines can only sail against the current at full speed, and once they sail at full speed, the huge noise will be exposed to the British.
Now, he can only sail quietly at low speed. Now, a sudden intrusion of water almost stopped his submarine abruptly, but he still did not give up.
Waiting for the opportunity!
A few minutes later, suddenly, a bigger shaking came!
"Attention, get ready, we are about to enter Scarpa Bay!" Captain Prien said.
Coming soon!
The huge shaking just now was in the opposite direction. This is the Hoksha Strait is starting the gate. This current can just rush the submarine into Scarpa Bay. This is their only chance.
Sure enough, next, the entire hull became lighter and faster under the action of an ocean current!
As a submarine commander, you must use ocean currents skillfully! In this way, even without the engine, the submarine can sail! Historically, German submarines entered the Mediterranean Sea and did just that.
And now, with the help of this current, they successfully passed the seventh entrance and entered Scarpa Bay!
