1855 United States Tycoon

Chapter 628

Captain Hafs has now returned to the Navy, and he has a new submarine-U-92. This is a newly produced submarine. Compared with the original submarine, it is larger, more weapons, and more self-sustaining. The submarine’s underwater displacement has reached 1,200 tons. There are six torpedo tubes in the bow of the ship, which can launch powerful 533mm heavy torpedo tubes. There are also two such torpedo tubes in the tail. . In addition, the torpedoes stored in the torpedo library are enough for Captain Hafs to play well on the hunting ground of the Atlantic Ocean.

But what made Captain Hafs even more happy was that the above finally let go of their hands and feet, allowing them to freely attack any freighter sailing on routes to Britain and France, which will naturally give Captain Hafs more records and Opportunities for promotion.

Five days ago, Captain Hafs’ submarine attacked a container cargo ship sailing alone and sent the cargo ship into the sea with two torpedoes. Three days ago, Captain Hafs’ U-92 attacked a cargo ship full of gasoline and blasted it into a torch with a torpedo. This morning, Hafs sank another cargo ship. Calculated in this way, although he has left the battlefield for a while, Hafs’ blessing seems to have come back, and his name has once again appeared on the sinking rankings. Of course, because of the time he was delayed before, he is far away. The top of the list is still a little bit far away, and everyone’s results have been ascending very quickly over the period of time. Maybe when I go back this time, there will be a big change in the ranking on the sinking list. Therefore, Hafs must work hard.

Hafs’ submarine has been a semi-submersible practicer on the ocean at low speed, but until the sky was completely dark, he did not encounter any more targets. After the sun had put away the last ray of afterglow, Hafs let the submarine It completely floated to the surface of the sea, and allowed the crew who had spent the whole day in the small cabin to go up to the deck in turn to breathe.

At this time, the rare wind on the sea disappeared, and the always violent Atlantic seemed to be asleep, and it was as peaceful as a large pond. At this time, the moon has not risen, and the sky is like a black velvet cover studded with various shining gems covering the sea. The submarine is shaking gently, and the slight waves gently wash the submarine, sending out gently The buzzing sound, and the low and sudden noise of the diesel engine of the submarine, made people feel exceptionally quiet.

Captain Hafs lowered his head and looked at the watch on his wrist. This is a premium watch from United States. It is a must-have for submarine commanders of the German Navy because it has a special function, that is, its The hands and dial have a faint luminous glow, which is especially suitable for use at night when there is light control.

Luminous watches are actually nothing in later generations. Later generations generally use fluorescent materials to achieve this effect. Some fluorescent materials can be excited as long as they are irradiated by light, and then they can fluoresce by themselves in the dark. But there is a problem with the luminous watch in this way, that is, its luminous can only last for a short time. If you need to work in a dark environment for a long time, this kind of watch is not suitable.

But in this era, this is actually not a problem for MacDonald, because they have other things to replace the fluorescent materials used in later generations, that is, a compound of uranium, which can automatically fluoresce at night because of its radioactivity. Of course, in later generations, this compound can’t be used indiscriminately on things like watches. Think about it, people in later generations are so expensive and allergic to wifi radiation. But this thing is actually nuclear radiation, maybe It will cause problems such as cancer, deformity, and transformation into Ultraman. But in this era, all of these can be ignored. Anyway, people in this era don’t know that ionizing radiation can harm their health. Therefore, even Morgan, who likes to follow the fashion, wears this type of luminous watch. Of course, the simple Scrooge would never use such a luxury.

It was already ten o’clock in the evening, and Hafs waved his hand and drove the sailors who were still on the deck back to the cabin, and then he was ready to go down. At this moment, he suddenly saw that there seemed to be a little on the distant sea. Fire light.

“What’s that?” Hafs thought, so he took the large telescope from the watcher Schiller.

The telescopes of this era lacked coating technology, so the imaging under low light conditions is quite poor. If this is an army telescope, it is estimated that Hafs can’t see anything, but the telescope equipped with the navy’s submarine takes into account the problem of night use, and the solution is simple. The amount of light is not enough to make it. The telescope objective lens in the Army’s hand has a caliber of only 30cm, while the one in Hafs’s hand has an objective lens with a caliber of 80, but the magnification is only seven times lower than that of the Army’s small items. Multiplier, this thing can barely be used at night. Of course, increasing the diameter of the objective lens will also cause a lot of problems. For example, the weight of this thing is much heavier than the army guy’s hands. Fortunately, there are shelves on the submarine. It can be used on a shelf.

Through the binoculars, Hafs could see clearly that it was a British fleet with a dozen ships faintly. As for whether there is an escort destroyer, Hafs can’t see clearly.

Hafs estimated the distance and considered the course of the fleet almost parallel to himself, and then simulated a chart in his brain. He found that if he immediately changed the following course, he should barely be able to catch up, but , Which requires the submarine must always sail on the water.

“What to do?” Hafs thought. If it was daytime, he could only watch the fleet escape, but it was night. “I chase on the sea at night, the enemy shouldn’t be able to find it, right?”

“Our submarine is very low. From any British ship, we are looking down, so that we automatically blend into the dark back of the sea. In the scene, now there is no moon, and the track brought by high-speed driving is the same. Invisible, you can sail on the sea, or even approach the enemy directly from the sea, treating the submarine as a torpedo boat, and attacking directly from the sea.” Hafs thought about this, and hurried down into the cabin, looking for it. The deputy captain came to discuss.

“Hafs, I think this idea is good.” After listening to Hafs’ thoughts, Deputy Captain Ram said for a while. The submarine force is well treated, so the morale is relatively high.

“Well, let’s take a risk.” Hafs replied.

…

Just as Hafs speculated, the British never found a submarine that had killed the merchant fleet from the sea. This was entirely because the sea was too dark, and the German submarine was painted black and gray. The paint is so that almost nothing can be seen when looking down. In fact, not to mention the submarine that is almost the same color as the sea. Even the snow-white iceberg is not so easy to find at night. Otherwise, there will be no ice sea sunken ship in history.

As for the sound of submarine engines, it was also drowned in the roar of the entire fleet of machines. There are sonars available on the British destroyers, but passive sonars at this time can’t be used to judge the position at all, and can only provide a vague warning. Judging the position must rely on active sonar. But this kind of early sonar is still very important, because an experienced sonar soldier can fully hear the propeller sound of a submarine sailing under the sea, because when sailing below the surface, the sound of the submarine’s propeller and other ships The sound of the propeller is quite different. Once they hear such a sound, the destroyer will be ready for battle and turn on the active sonar to search the sea near the fleet. Although this does not necessarily catch the submarine, at least it can put a lot of pressure on the submarine, making it more risky and less efficient. But now, because the U-92 is sailing on the sea, the sound state of its propeller has changed significantly, completely different from what it usually does when diving under the sea. In addition, because the U-92 is now on the water, the active sonar for searching underwater targets is naturally useless. Therefore, by adopting a night attack on the sea surface, Hafs turned the latest sonar equipment on the British destroyer into a display.

In this way, just after one o’clock in the morning, the U-92 submarine caught up with the merchant fleet.

“1, 2, 3, there are three destroyers, two in the front, and one in the back.” On the watchtower, Deputy Captain Ram was pointing his finger at those on the back of the bright sky. The scene was very clear. The black silhouette of the British ship said in a low voice to Hafs standing next to him, as if he was afraid that his own voice would be louder and would be heard by the British. But this worry is superfluous, because the distance between the two sides is about one kilometer, and the British don’t have such a wind ear.

“We can get closer.” Hafs said, “You see, there is a big gap between the two ships. We first approached to about 500 meters, and launched a torpedo at target No. 5. , And then quickly insert this gap so that we will be blocked by the No. 6 ship. When the torpedo explodes, we will not be illuminated by the fire, and then we will launch a torpedo at the No. 2 target, and then Drive over to the No. 4 ship and use it to avoid the flames… what do you think?”

Ram thought for a while, nodded and said: “It should be possible, you are the captain, give the battle order!”

“Well, Ram, you go down to control the submarine, I will command here, let us fight bravely for Germany.” Hafs said.

“Germany is above all else!” Ram replied. Then came down from the control tower and entered the cabin.

“Turn the rudder to the 300 direction.” Hafs gave his first order, and a new submarine combat mode also began in this battle.
