Sonar, not reliable.
The mute performance of submarines in this era is not good, and it is impossible to reach the level of ocean black holes in later generations. The pump jet propulsion will not be mentioned, and the basic seven blade large side inclined propeller will not be produced, so there must be some noise.
However, in contrast, the performance of sonar is also backward, lack of advanced electronic technology, the sound range that sonar can hear is very small, and lack of analysis and processing means, so it is normal that sonar can not hear the noise of submarine.
At this time, it is very important to have more lookouts and search the sea carefully. What if the lookout can find the vent pipe and periscope on the sea?
This is the same as arranging observation posts for air defense early warning.
In fact, if there is a mature sea search radar, the periscope used to scan the sea surface is the best. Unfortunately, for the same technical problem, as long as the wind and waves are slightly larger, it can not filter out the clutter on the sea surface.
Or the naked eye is the most accurate.
With this idea, the sailor critis carefully observed the sea and searched bit by bit. Finally, he seemed to find something on the sparkling sea.
He quickly adjusted his telescope, magnified it, and then magnified it. When it was clearly imaged in the eyepiece, he finally exclaimed: "thirty degrees on the port side, five nautical miles away, I found a suspicious target, which may be a Submarine Periscope!"
His voice was like a click of thunder on a sunny day, and the whole formation was startled in an instant.
Countless telescopes looked at the direction he indicated and searched the sea. At the same time, in the middle of the formation, a destroyer drove at full power and met up, and the deep bomb launchers at the tail were ready.
But nothing.
"Critis, are you mistaken?" The Captain stood in his position and looked at the sea with the same telescope. He didn't find anything, so he asked with a frown.
"No, I can see very clearly." Critis said, "there must be submarines, there must be submarines!"
He firmly believed that he was right.
"Well, it seems that you are too nervous recently. You can go back to the cabin to have a rest, have a good sleep and come back on duty tomorrow." The captain said, "change someone."
Are you really too nervous? Critis shook his head reluctantly and walked towards the cabin.
On this ship, the most important equipment is transported. It is said that it is an anti tank weapon urgently needed by the front line. There must be no mistakes. In the whole fleet, their pressure is indeed the greatest.
"If German submarines appear, they will attack us." The captain said, "there's nothing to make a fuss about."
They don't know that they have made serious mistakes.
Underwater.
"It was so thrilling just now. I could almost see the sailor looking at us from the periscope." On the u-107, vice captain Ruth said, "so I was quick in my eyes and hands and quickly put down the periscope."
"In fact, if we just started, we could kill several cargo ships." Another chief mate said.
Hessler shook his head: "we just can't do it. Relying on ourselves, we can't eat so many cargo ships. We must kill all cargo ships at once and surround them like wolves. Now, we'll keep up with their fleet and wait for our companions to come at the same time. Now, start the AIP System. "
If it's an ordinary submarine, it's no problem to keep up with the cargo ship on the water. After all, the speed of the cargo ship is quite low, but it can't be tracked for a long time, because the power of the submarine's battery is quite limited, and after a period of time, it has to float up and charge.
Now, the submarines after the U-100 are AIP submarines. Using Stirling engines, they can sail at low speed for a long time and keep up with their surface cargo ships. There is no problem at all!
The propeller at the tail of the u-107 turned and gently stirred the sea water. The noise made by the submarine spread to the cargo ship formation and was almost inaudible. After the cargo ship formation left, it followed again. This immediately made the people on the submarine more strange.
"It's past ATU island. They haven't turned around yet. What do these cargo ships want to do?" Ruth asked involuntarily.
"I think they are going to change their route and transport the goods directly to the Far East." Hessler made such a judgment, and when this sentence was finished, everyone present was happy: "that is to say, in the future, as long as we are near the base, we can hunt and kill the Soviet transport ship?"
At the beginning, there was only one nuclear submarine, which could only wander on the Arctic route. Therefore, the Soviets simply went to the Far East for transportation. Now, Germany has established a nuclear submarine base on the four northern islands of Hokkaido. The Soviets did not notice that it was foolish to design such a route.
Unfortunately, the submarines patrolling in the Bering Sea are about to blow out. Fortunately, there are several submarines behind, which can intercept them head-on as soon as possible.
The day passed.
For Soviet sailors, every day was like a year, and every day passed, they would take a long breath and live another day.
When the sun rose again from the sea in the East, the whole fleet could see the Kamchatka Peninsula on the starboard side from a distance.
The Soviet is near.
"Well, did you sleep well last night?" When critis stood on the lookout platform set on the side of the ship again, a voice came in his ear.
"Fortunately, it seems that I must have been dazzled yesterday." Said critis.
If I saw the German submarine yesterday, I would have been attacked yesterday. As a result, it has been calm until now.
I must have been dazzled and made everyone nervous for more than an hour. Now, critis is is quite guilty.
"Never mind, young man, do a good job." The captain patted him on the shoulder: "everyone's maturity needs a process. Don't have pressure, and then work."
The captain returned to his captain's room, and critis put his eyes on the telescope and began to observe again.
What's that?
Critis rubbed his eyes and looked again.
As like as two peas yesterday.
The sparkling sea is shaking, and on this sea, there is a thin cylinder like thing half a meter high. This thing is churning with the waves, but it is as stable as Mount Tai. Isn't this a periscope?
No, I must be dazzled.
Critis didn't believe he had this luck. He swept it all at once? In that case, he would be God's chosen man to warn the whole fleet.
Turn to the other sea and have a look.
When he turned telescope as like as two peas, and then searched again, he adjusted the focal length and his vision became clear.
Please report us if you find any errors so we can fix it asap!
