My German Empire

The spell of the destroyer holds his headphones with hands, and the gods listened to the movements from the headphones, and I am afraid that I will miss any strange sound.

The word Sonar is the first American term used in the Second World War. It is Sound, and RANGING's first letters. The UK also called Sonar as "ASDICS", representing the anti-submarine exploration investigation committee.

There are two ways to work: proactive and passive.

The passive way is just "listening", that is, only the target direction is received by the radiation noise of the target; the active mode is the pulse or frequency modulation signal that itself issues a certain frequency, relying on the reflected wave of the target (similar radar). .

The subsequent sonar is developed into a variety of advanced systems including echo test depth or depth detectors, rapid scanning sound, side mesh and WPESS (intracerene electronic sector scanning). But at this time, the sonus is still raw, even many defects.

Waiting for a long time, I didn't see the sound workers responded. The destroyer captain Braddy wrinkled. "Sagi, now I haven't found it yet?" He firmly believes that he does not judge the mistake, and it will be able to find a German submarine in this vicinity.

The sonards shook their heads. "There is no big official, there is no abnormal noise near this. Either a German submarine closed the engine, or it has left." There is also a possibility that Braddy's judgment is wrong, and the root finds the wrong position.

"..." Brundi's brow wrinkled more deeply, although some reluctant to admit, he couldn't help but doubt it to his judgment.

At this time, another destroyer came to help, two destroyer ships discussed one, decided to expand the search.

Just when two destroyers played with a submarine, Krazzer's Tiger shark submarine has captured a goal outside of two kilometers, and a large freighter, the tonnage of this freighter is bigger, it looks There are 50,000 tons, and the ray is called "Jasmine".

I just had a freighter, and the vessel on the waterway learned that there were German submarines nearby, and I consciously increased the speed. It can be increased by two or three sections, it is not much. The sailors on the boat have flocked to the boat, nervous glances on the nearby sea.

Suddenly, a sailor on the jasmine carousel saw a steadily in the low ups and downturn.

"??" This is a bit strange, there is no reef near this nearby, is the Haiyan practice water drifting? He knows that Haiyan will not swim. Although Haiyan is basically living at sea, looking for the main source of food is also on the sea, it can capture the food in water by flight in the sea. But they don't swim. When they are tired, they will choose some trunks of the sea or rest in the sea rock.

Unless there is something in its feet ...

"Hey! Hey! There, there seems to have a submarine!" The Haiyan may stand on the submarine! And their boat just is the T-bit bit of the submarine, saying that the submarine is ready to launch the torpedo!

"..." Krazzer looked at the sailors in the freighter pointed to this side, couldn't help but have been bored out?

He naturally didn't know that there was a Haiyan on the periscope, just thinking that these guys saw his periscope.

"No. 3 4th fish thunder, set a deep thirteen meter! Laun!" This jasmine freighter is much larger than just that tonnage, a torpedo is afraid, and he launched two magnetic torpedoes.

After the launch command, he recovered the periscope.

When I saw the Haoyanteng, the sailors on the jasmine carousel suddenly felt the pot, which is obvious that the German submarine has leaving the hidden mirror. It is likely that they have already launched the torpedo!

"A full speed !!" Jasmine's captain is already scared, and the command is loud. The host is accelerating,

Breddy, who is searching in the German submarine trace, is searching to the Jasmine, and not help. When did this submarine run? Or there is more than a submarine here, and the neighborhood has really laid a German "Wolf Group"? It is true that the wolves they should launch attacks at the same time, and it is impossible to attack.

Or is this, their tiger gathered from the mountain?

For example, the submarine may not be hidden in this nearby, wait until they go to search for another submarine, it will come out to continue to attack the past boat?

One of the two captains, another destroyer continued to search here, Braddy rushed over the submarine.

Breddy commanded the destroy ship to turn around, while curse in the heart, is the letters above the fool? The waterway is so long, only their destroyers are responsible for patrol, each boat has to kick out the distance from the long distance, once the situation, it is impossible to support it in time. What guys think that the boat is a car? Can you take a speed of 100 kilometers in the throttle?

"Jasmine, jasmine, received, please answer, please answer!" While accelerating, the radio is also called. "Please inform the enemy submarine."

Soon Jasmine is coming back. "My ship left the side of around 1000 meters, just they have received the hidden mirror, may ..."

"boom!"

"boom!"

The other party's voice has not fallen, the two dramatic explosions sound from the bottom of the jasmine cargo ship, and the water column is stirred up.

Explosive force extrusion sea water forms terrible energy, under physical conditions of water, a little uncomfortable, turning the gaseous impact force into a solid liquid transfer, !

This terrible force is lighter to distort the keel structure that supports the entire ship until the break. A torpedo is enough to have a half of the barters of Jasmine, and the second fish thunder that follows will make it cool. In the sound, the hull broke from the central part and became two paragraphs before and after!

"God!" Looking at the two boats, there were constant people to jump into the sea, but Braddy could not stop for rescue. If you don't find the dead submarine, I don't know how many cargo ships have been killed.

In this time, I have a definitive position, and they immediately rushed to the place where German submarines launched torpedo. "Society, quickly find out the female group!"

The sonar put the headphones on the ear, try his best to hear the accepted sound wave information, and other people around me, even the atmosphere did not breathe, and I was afraid to affect the work of the sonas.
