My German Empire

"The boat is long, the 'Sea Carrier" seems to be shattered! "

In the distance, the other US military submarine, the sorrowful look of the sorrow, and reported to this bad news. But next second, his face suddenly changed. "Worse, the German destroyer will come toward us !!"

"Damn!" The boat failed to remember the "Seahu", and decisive. "Close the power system !!" said that this is a quite risky decision, once the power system is closed, the submarine can only be able to move in the bottom of the water, but the "Sea Buchen" will warn them, I want to compete with the Germans, then It is purely looking for death. He can only fight, close the power system, the whole submarine is so quietly in the 50-meter seawater, hoping to escape the search of the German destroyer.

Table tennis! Table tennis! Table tennis!

As the destroyer is close, the sound wave sound on the submarine housing is getting loud, the cavity effect enlarges this sound, and the sailors in the submarine can also hear a clear two. The sonar is in time to adjust the volume of the headphones to avoid shocking eardrum.

Everyone is nervous, even the atmosphere dares out, face each other, and communicate with your eyes. "What is this sound ?!" They used to have never heard this strange voice.

"God !!" At this time, the sonar suddenly called. "This is the active voice! The descendant of the German is equipped with the initiative !!" "" "" "" "" "" "" "" "" His uncle is an expert in studying acoustic wave. I have heard of the principle of active sonar. I didn't expect the Germans that have been successfully developed and equipped with active.

"What ?!" "Listening to everyone is shocked. According to the initiative of the active sonar, even if they closed the power system, he will not escape the German active search !!

The boat is rushing to ask. "Is there any way to avoid the detection of active sonar ?!"

The expression of the voice is more ugly than the cry. "As far as I know, only one, that is, dive to the seawater jump, the jumper will refract the acoustic wave transmission."

The so-called sea water is a water layer that changes with a significant change in seawater parameters. Refers to sea water temperature, salinity, density, sound speed, etc. There is a mutated or discontinuous aqueous layer in the vertical direction.

It mainly has a temperature jack, salinity jump, density jump layer, and a sound speed jump layer. Temperature jumps often exist in the ocean and affect salinity, density and sound speed jump. The salinity jump appears in the estuary region or has a large amount of precipitation, evaporation and ice. The density jump typically occurs in the mixture of sea water, the two water groups, the water flow, water temperature, salinity, except that the estuary region and the salinity vertical gradient are particularly large, and the density jumper is substantially and temperature jumps. Layer is coincident. The sound velocity jump is usually formed due to the temperature, pressure and salinity of the seawater, and the sound propagation speed is formed in the vertical direction.

These jumps have a positive role in the hidden underwater communication and submarine. The use of water sound equipment is preferably used in deep silence, and the submarine sailed in the deep sound can detect a distance from the distance. The sonar signal transmitted over the sound velocity is not easily detected, and the submarine below the sub-entertaine is greatly reduced. If the seawater jump is small, the upper depth is deep, the thickness is large, and the long-lasting stability will form an irregular acoustic reflection, which greatly reduces the operational performance of anti-submarine, causing difficulties to anti-submarine action.

"Xie!" They don't know the hydrological situation here. If they have dive, even if the limit of the submarine is not necessarily arrived!

Just when the yacht hesitated, the sound of the voice became inchabulent. "The long, the German destroyer cast deep water bomb !!"

He hesitated a second, the boat failed. "Start the engine! Empty the water tank !!"

After a few seconds, the deep water bomb exploded in their top, and the huge sound made the voicemarks.

The shock wave of deep water bomb explosion is with a thunderous momentum, sea water with a huge pressure, pressing the housing of the submarine! The rear shell steel plate of the submarine can't take the terrible impact of the impact, the moment is distorted, the turbine cabin has split a big mouth, the seawater under the five atmosphere is like a huge fist, and the birth will follow several The sailor shot flat on the bulkhead. Instantly, it is madly flooded to other cabins.

"Close the hatch! Emergency floating!" The yachboard has reached an emergency order, and the submarine drains and floated with the fastest speed, and it is very fortunate to escape the rest of the deep water bomb. When the upper floats are more than 20 meters long boats to the correspondent. "Waiting for us to float the water, immediately send the news of the German equipment to the active sound!" Otherwise, the submarine does not know how much loss.

Said that he rose the hidden mirror, and he saw the gun mouth of the German destroyer has been aligned.

"I hope they can catch the prisoner." The boat was just prayed, and he saw the guns spurting, then he didn't know anything.

Sinking this submarine after a sinking, the German destroyer continued to search in this sea area until it was determined that there was no other submarine to return the message back to the fleet.

"Command, we sinkled two American submarines."

Haierman commander nodded. "Strengthening the warning, don't let them transport to the island."

Wahu has been surrounded by them for eight days. And even God stands on them. The original rain is full of Pacific Ocean. In this eight-day, Wahu is only a small rain, but it is not enough to follow the defenders in the island. For up to three or four days, these defenders will lose combat power because of water shortage.

The other fleet sent to the middle of the island easily occupied the middle of the island. Although all the amenities on the island have been dismantled, the US military destroyed is clean, but they don't expect to receive these facilities from the beginning. The accompanying engineering team has begun to repair the airport and port on the island, and the middle of the way will become the base of the German Navy.

In the underground headquarters on Wahu, the Wilson commander once again asked how many problems did not know how many times. "Contact to the supply submarine?" Because the lack of water, his lips have been made, the whole person is sluggish.

The correspondent is weak. "Command, replenish the submarine may be snorkeling. Press the previous news, it has been 50 kilometers away here."

50 kilometers, even if the submarine is not used for six hours in 5 knots.

Unfortunately, left and other right, etc., wait for more than a dozen hours, I don't see any news.
