Captain Prien's submarine was the first to reach Scarpa Bay, and as early as the early hours of the morning, he crossed the waterway and arrived here to lurk. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

At that time, if he wanted to attack, all the warships in the harbor, whatever he chose, of course he would first target the aircraft carrier of the Ark Royal.

Or, other aircraft carriers, as well as battleships, pick up a big pick, and if you launch four torpedoes at once, you won't believe that you can't kill the other party.

However, he did not move, and if he did, he would have disturbed the British here and made them on alert, and the air raid this morning would not have been possible.

According to the plan, as soon as your own bombers start dropping bombs, the U-47 submarine can move.

In fact, he did the same, sitting under the water and keeping silent, and in the early morning, when he heard the first explosion on the water, the officers and men in the entire submarine immediately took action.

Start the engine and float to periscope depth! The sailors were quickly preparing.

The submarine of more than 800 tons, with a huge body, is slowly floating, and the two AEG GU 460/8-276 electric motors in the tail burst out with a maximum horsepower of 750 horsepower, and the propeller in the tail soon reached a maximum speed of 296 revolutions per minute.

At this time, there is no need to worry about the opponent's anti-submarine system, after all, the other side has already been bombed, and it is too late to deal with the bombers overhead, how can it care about the underwater situation, and the sound of explosions one after another will cover the sound of the submarine.

Now, they must move quickly, take their seats, and prepare to attack!

And in the bow torpedo compartment, the sailors were ready, just waiting for the fierce attack to begin!

Operating a submarine is not as easy as driving, although they have already operated it at the most skilled speed, it still took about three minutes for this submarine to be leveled at a depth of ten meters under water, and then, on the bridge of the submarine, the periscope stretched out.

At the same time as the periscope stretched out, on the side of the bridge of the submarine, a thicker tube, was also slowly rising.

This tube, much thicker than the periscope, was placed vertically upside down on the submarine hull when it was not in use.

Now, with the hydraulics on the side, the thick tube stands upright, the roots turn, and an automatic locking pin secures the tube to the rear of the podium enclosure.

On submarines, the use of periscopes has been around for a long time, and it can be said that since submarines entered the naval sequence, periscopes, such optical devices, began to be equipped.

However, this thicker tube, which is now classified, is a piece of equipment that greatly increases the combat capability of submarines, and its scientific name is called submarine snorkels.

Submarines sail on the water with diesel engines and charge their own batteries at the same time, while underwater, they can only use batteries.

The power of the battery is precious, for example, if you sail at top speed, you can't hold out for even an hour.

Therefore, submarines in this era, most of the time, were sailing on the water, and only when they needed to attack, they dived underwater.

However, surface navigation is dangerous, and the ubiquitous anti-submarine aircraft are the greatest threat to submarines, so it is quite urgent to allow submarines to sail under water and use diesel engines.

This device is the snorkel.

The diesel engine cannot sail underwater because the diesel engine needs to draw in air and remove exhaust gases at the same time, and now, this pipe is here to do this.

The inside of this tube is divided into two halves, half intake and half exhaust.

As long as the tube can go to the outside, it can exchange air with the outside world, so that although the submarine has not yet surfaced, it can already start the diesel engine in the tail!

For the captain of the submarine, keeping his battery fully charged at all times is what he hopes for the most, and at that time, he is the most confident.

Since only a small snorkel is exposed, it is also difficult to be detected by surface ships.

There is a floating mechanism at the top of the intake pipe, similar to the float in the toilet bowl.

When the mast is in the water, the floating mechanism automatically closes and blocks the air intake pipe, so that the outside seawater does not enter the submarine through the air intake pipe. When the mast is exposed to the water, the floating mechanism opens on its own, allowing the air intake pipe to communicate with the outside world.

Now, as the tube continues to turn, soon, when it turns upright, the top is exposed, the snorkel opens automatically, and the seawater remaining in the intake pipe flows into the auxiliary ballast tanks on the boat.

"Start the diesel engine," Captain Prion shouted, staring his eyes at the periscope in front of him, almost synchronously, and after the snorkel went out, the periscope also went out.

In the back, two 1400-horsepower diesel engines of the MAN company emitted a muffled sound, which was quite familiar to submariners.

After the diesel engine is started, the exhaust pressure blows the seawater out of the exhaust pipe. A faint green smoke appeared on the surface of the sea.

Historically, Germany experimented with this device in 43 years and installed it on submarines produced in 44 years, in fact, this technology appeared very early.

For example, as early as 1938, the Dutch Navy conducted a series of experiments on submarines sailing at periscope depth, using a single-pipe ventilation system to achieve underwater diesel propulsion, so that the submarine has almost unlimited underwater range.

Unfortunately, the German Navy did not notice the importance of this invention at first, in their eyes, this device was only a means of circulating air to submarines.

Now, this snorkel technology was proposed by Ciric at a certain conference on naval equipment, and then, after the development of experts, it has developed and matured, and has become a killer feature of the German Navy's submarine force.

Diesels in the tail were rumbling, and in front, the atmosphere was tense, and for the submariners, their attack was about to begin.

After raising the periscope, Captain Prion immediately began to observe the sea, at this time, one after another, the battleships were on fire, thick smoke was billowing everywhere, and there was hardly a worthy target in sight on the sea.

Leave me something! Captain Prion was extremely depressed.

After a turn, Captain Prien was still happy: "Left full rudder, ready to attack!" ”

On the sea, a few kilometers away from the port, there is actually a big guy left, although the angle problem, Prien can not distinguish the specific model and name of the other party, but it is definitely a large battleship!

The battleship is emitting black smoke, but it hasn't sunk yet, so let's just send it to hell!

Left full rudder! The tail of the submarine churns the current, belongs to the hunt of the submarine of the U-47, no, the slaughter officially begins!
