"There is no anomalous contact with the sonar." The sonar soldier reported loudly.

The so-called "contact" means "to find the target", and for the submarine, each "contact" of the sonar can mean trouble or opportunity.

And the absence of sonar contact suggests that the submarine is now at least safe.

"Periscope depth." After Erich gave the order, the submarine began to float, and after a few moments, the submarine's sloping deck gradually stabilized, Erich pulled the button, and the periscope rose from below the deck of the command module.

Erich put his hat on his back and put his eyepieces on his eyes and began to look at the sea.

"The sea is safe, there are no enemies." Erich put away the periscope, "Change the lights, raise the snorkel." ”

The light in the boat then switched from the red light of the battle to the usual white light, and then as the snorkel was raised, the ventilation equipment in the boat also began to operate, and the normally sealed cabin bravely blew from the front hatch to the rear hatch.

"The British didn't know we had chemical air purifiers," Erich told the technical sergeant major, "so they saw that we hadn't surfaced for so long beyond the submersible time, and they thought we might have lost our ability to float and were suffocated in the water." ”

"Thanks to high technology." Technical Sergeant Major smiled, "Speaking of which, we can be regarded as the number one technical branch in the Navy, so the impact of technological development on our combat effectiveness is too great." ”

"Sir, the communication antenna has been raised," the voice of the communications soldier came through the microphone, "do you want the headquarters to send a report?" ”

"Okay, send a report to the command, our boat has just used a wire-guided torpedo to achieve what may be the first actual combat hit of a wire-guided torpedo in human history. Judging from the remnants on the surface of the sea, the large ship suspected to be Tennessee-class that was hit has sunk. Our ship will continue to track the enemy ship. ”

Erich paused, and added: "Actual combat has proved that wire-guided torpedoes are an effective weapon, and I hope to install them as much as possible to strengthen the attack and survivability of our submarines." ”

The use of wire-guided torpedoes can be used to occupy positions without risking death, and the survivability of natural submarines will be improved, and this simple truth must be understood by the entire naval submarine fleet, so the navy has been studying long-range torpedoes so that submarines can launch attacks outside the enemy's anti-submarine defense circle. However, the tragic hit rate of long-range torpedo attacks has stubbornly hindered the Navy from achieving its goals.

Even a well-trained German submariner could not guarantee the hit rate when firing a torpedo at a distance of more than seven kilometers from the target, after all, the torpedo was subject to too many interference factors, not to mention the surface currents of the sea, it was possible to push the torpedo out of the original intended course.

Whether a torpedo fired at a distance of more than 10 kilometers can hit or not depends basically on whether the person who pressed the launch button is handsome enough - to put it in a more prosaic way: whether it can hit or not depends entirely on luck.

Sometimes, with good luck, no one can stop it, for example, a Japanese submarine in another time and space has achieved an effective hit at a distance of more than ten kilometers.

At that time, the Yi-19 fired six torpedoes at the USS Wasp, and as a result, three hits, and the remaining torpedoes flew more than 10 kilometers after missing the target, hitting the battleship USS North Carolina in another US aircraft carrier battle group, forcing the battleship to return to the US mainland for repairs out of the battle sequence.

After the completion of this attack, the commander of the I-19 did not know that he had also severely damaged a battleship, and the Japanese base camp was completely unaware of this, until the U.S. forces occupying Japan after the war compared the combat files of the two sides, and found that this hit still had to be counted on the head of the I-19......

But there was only one such chance in the whole of World War II.

Therefore, the use of wire-guided torpedoes is of great significance, even if it only increases the hit rate by a little bit, it is enough to affect many things, not to mention that according to the actual combat just now, the hit rate of the line-guided torpedo can be increased by more than a little bit.

**

Not long after Lin Youde received a report that the British fleet was approaching Alexandria, the telegram of U571 was transferred to him.

"That's right, the first actual combat hit of a guided torpedo in human history was born," Lin Youde looked overjoyed, "This can also silence those admirals who are clamoring for the use of sound-guided torpedoes." ”

The biggest reason why Lin Youde did not choose the sound self-guided torpedo was that he knew that the British, who had already studied the sound self-guided mines deployed by Germany, would definitely take countermeasures, and in another time and space, the British used noise jammers to interfere with the aiming of Germany's cutting-edge self-guided torpedoes.

It was precisely because Lin Youde knew about this situation that he stopped the idea of the technical department of the German Navy. In fact, in Lin Youde's view, in the current technological environment, it is too simple to jam guided weapons, but it is even more difficult to create an electronic center that can allow guided weapons to detect interference.

Therefore, the use of purely self-guided weapons at the moment is purely self-defeating.

Even the Fritz series, which is controlled by humans to carry out attacks, is often paralyzed by electronic interference by the British or American military.

In contrast, wire-guided torpedoes are much more resistant to jamming - it should be said that there is no possibility of being jammed by the enemy. When Lin Youde decided to go all out to promote the development of wire-guided torpedoes, he was actually still a little empty in his heart, after all, he knew that in another time and space, the Germans vetoed the plan of wire-guided torpedoes, and instead went all out to study sound-guided torpedoes to identify and attack targets.

Lin Youde didn't know what the Germans in another time and space had verified when they were demonstrating the two torpedo schemes, and he didn't know why the wire-guided torpedo was abandoned.

In case the first-line guide torpedo has some problems that he Lin Youde, a weak chicken liberal arts student, can't find out, he Lin Youde will become the laughing stock of those old-school Junker-born naval officers this time.

But now it seems that this worry is superfluous, and the wire-guided torpedo is good, so Lin Youde is more and more unable to understand why Germany, which is in another time and space, should abandon the wire-guided torpedo program and give priority to the development of sound-guided torpedoes.

Maybe it was he Lin Youde who had been bouncing in Germany for so many years, and the "butterfly effect" produced eliminated the technical problem that shackled the wire-guided torpedo.

In any case, after all, the U571 sank a battleship, which is a result that can be boasted of, and Lin Youde is sure that it will not be long before he will issue the entire crew of the U571 with an ankh.

Lin Youde was thinking about the division of medals, when another confidential officer rushed into the command room with a telegram.

"The British Divine Queen is on her way to Alexandria."

"Don't panic, our goddesses are in Alexandria now, and they will deal with this group of British ladies.

In fact, there are two gods from India, but Lin Youde didn't notice this at all, and no one in the whole room dared to remind Lin Youde at this time.

Of course, it doesn't matter where the god comes from.

"Have Alexander's troops completed their mission?" Lin Youde asked the confidential officer who had just come in, but without waiting for the confidential officer to answer, he immediately said, "Send a telegram to report to them, whether they complete the task or not, they should start retreating." ”

Lin Youde had long thought that the British would use their fleet to force a breakthrough through the Strait of Lunnis, and then use the numerical superiority of the gods to reoccupy the lost Alexandria. Therefore, Lin Youde never thought about holding on to Alexandria from the beginning, and the main task of the ground troops he sent was to blow up all kinds of fleet support facilities in Alexandria. Key facilities, including the dry dock in Alexandria, were all on the list of German destruction.

Once all these above-ground facilities were destroyed, Alexandria's ability to support the fleet would be greatly reduced. Fleet logistics can be quite complicated, and it is not as simple as replenishing fuel and ammunition.

Lin Youde could imagine what the situation was like in Alexandria at this time, the city must have been filled with all kinds of explosions, and the British had been working hard in this port for so many years was gradually turning into ashes.

When Cunningham saw the devastated port, he must have been half angry, and scolded the British Army for its incompetence and the destruction of the Navy's years of hard work.

After the two confidential officers left the room, Lin Youde stared at the map and whispered to himself: "However, it is also very unpleasant to let the British occupy Alexandria all the time." While the sabotage could paralyze the port for a long time, it would be unpleasant if the British did deploy more than four gods here. ”

Lin Youde tapped his fingers lightly on the tabletop, and began to think about how to add another Shenji combat power from there to his own war zone, so that it would be simple and pleasant to take Alexandria.

It's a pity that he listed all the gods in the current Human Innovation Alliance, and found that he couldn't squeeze out more gods at all. Purely in terms of absolute numbers, the Human Innovation Alliance and its opponents are half a pound and eight taels, but a large part of the alliance's gods are on the side of the government of the New Ming Republic, so in Europe, the Human Innovation Alliance is slightly inferior in terms of the number of gods, and now it is just relying on equipment to forcibly open up with opponents.

Therefore, a situation like the current one is completely normal, and theoretically it is impossible for Lin Youde to find a way to change this situation.

Finally, Lin Youde shook his head and had to give up the idea of "squeezing out a god to reinforce himself", and comforted himself by saying that at least four gods were pinned down in Egypt by the enemy, so that the pressure on the gods on other fronts would be much less, and there might be some unexpected results on other fronts.

While comforting himself in this way, Lin Youde began to think about how he would "dance in shackles" in the desert of North Africa if he couldn't take Alexandria.
