Chapter 1296： Wolf pack attack

Chapter 1296 Wolves Attack

"You can attack." Dunnitz issued an attack order. "After the second attack, dive down quickly."

A few seconds later, with the action of the high-pressure air in the torpedo tubes, the lids of the three torpedo tubes at the bow of the boat were bounced off, and three torpedoes weighing more than one ton rushed into the water. After a while, they were driven by the heat engine. The torpedo engine started, a stream of exhaust gas was discharged from the mine body, forming a white wake underwater.

The same unprepared, the U190 submarine and U154 submarine attacked almost the same time. Before the Japanese fleet received the alert, the target ship No. 1 in front was blown to pieces by two torpedoes. , A huge fireball soared on the sea, and the power of the explosion far exceeded that of two torpedoes. It seemed that this time it hit a ship carrying arms.

The dazzling light illuminates the surrounding sea like daylight, and Dunnitz subconsciously put aside his eyes. The suddenly brightened vision in the periscope made his eyes a little uncomfortable.

"Attack the second ship immediately, hurry up! Leave after the fight!" Dunnitz ordered.

The U190 submarine turned 15 degrees to the right, and the torpedo tube on the back was aimed at the second transport ship. At a distance of 1,000 meters, while the opponent was still fainting, two torpedoes quickly rushed out of the torpedo. Tube, blow up the other side's face!

"Prepare to dive, start counting down!" Dunnitz just wanted to leave quickly. The first target he attacked just now had some accidents. The sudden light is very likely to expose his position. Now, he needs to dive quickly. , Leaving the battlefield before the Japanese reacted.

However, it may be that Dunnitz has been too smooth before. According to the law of conservation of RP, God, the old man thinks it is time to give you some hardships. At 4000 meters behind the U190 submarine, the Japanese destroyer Hatsushuang discovered this guy who was painful at night! And just as Dunnitz was worried, this destroyer found Dunnitz through the fire when it exploded on Target One!

"Shoot the artillery, get ready for depth bombs! Let's kill this guy." Nan Yun Zhongyi, the captain, roared through the entire Cambridge. Ten seconds later, three 120MM shells landed around the U190 submarine.

Thanks to Dunnitz's vigilance, he immediately dived right after firing the torpedo. When the destroyer Frost determined the location of the U190 submarine, only a half of the U190 command tower was still exposed above the water!

After the three rounds of shells were fired, naturally nothing was gained. However, Chuichi Nanyun did not intend to give up like this. For the destroyer Hatsho with a maximum speed of 30 knots or more, the distance of more than 4,000 meters is only a few minutes away. When U190 is completely hidden under the sea, the destroyer Hatsho Already arrived near where U190 dived before!

"Turn on all the searchlights, everyone, pay attention to the sea. There may be torpedoes in the torpedo tubes of this submarine! The depth bomb is prepared to set the depth. The first 10 shots are set at a depth of 15-25 meters, and the rear set is at 35 meters to 45 meters. Between! Prepare for anti-submarine warfare!" Lieutenant Nan Yun ordered.

How to fight anti-submarine destroyers in World War I? In this era when active sonar is not widely popularized and hydrophones can only be used to make do with it, there is only one kind of anti-submarine weapon, and that is to cover bombing with depth charges. As for how to find a submarine? Most of it was naturally discovered after the submarine surfaced, such as the U190 just now. It is still difficult to expect to find submarines by hydrophone and sonar. It can be said that the difficulty of submarine anti-submarine is more than 60% in search. And now, although only 40% of the difficulty remains, it is still difficult to handle, otherwise, the wolves of World War I would not be so daunting.

In general, Nanyun Zhongyi still has the ability, otherwise he would not become a general! In just a few minutes, he straightened out the whole thing. Just now, there were at least two big explosions when the first target was destroyed, so it is very likely that two torpedoes were hit. After that, the second When a target was destroyed, it exploded twice, and it should have hit 2 torpedoes. In this case, the German submarine has fired at least 4 torpedoes. And how many torpedo tubes in a submarine? Generally, there are 6 at most, 4 at the front and 2 at the back. Based on the location of the two transport ships, Nan Yun inferred that this submarine should have used the front and rear torpedo tubes to complete the double kill at the same time!

"This TM is a personal talent." Although it is an enemy, he attacked two targets at the same time in less than 3 minutes and succeeded. Nan Yun had to say admiration in his heart!

Well, if you have a good estimate, then the number of remaining torpedoes on this submarine will definitely not exceed 2 rounds! In other words, this shark that has just finished preying should be in a period of weakness, and the opponent's attack power has been reduced to the lowest level. If the torpedo tube needs to be reloaded, it will take about 20 to 40 minutes! So when launching an attack at this time, it is clear that the destroyer on the water has the advantage!

Under water, the speed of a submarine is generally 4 to 5 knots. This speed is the most economical. This also means that the speed of the submarine underwater is actually not as fast as riding a bicycle.... Therefore, for this kind of combat situation, Nanyun Chuichi has a great probability of destroying opponents through depth charges Do not underestimate the power of depth charges, take the Japanese 88 depth charges as an example , With a charge of 148KG and a detonation depth of 15 to 25 meters, if the submarine is within a range of 150 to 250 meters from the explosion, there is almost no damage. If the explosion distance is within 50 to 100 meters, it is possible to damage the submarine. Cause a certain degree of damage, such as moderate water seepage at the submarine shell rivets. The battery pack may be damaged. If it is close to 19 meters, the submarine will have a wide range of water ingress, the internal and external valves of the submarine will also have serious water leakage, the battery pack will be severely damaged, and it is even possible that the submarine cannot be submerged. If it explodes at a distance of 10 meters, then good luck, good luck, the inner shell of the submarine is directly destroyed, and the submarine hits GG!

Nan Yunzhong is also very particular about the setting of a pair of deep bombs. The detonation time is set earlier because the submarine has just dived, and if the opponent has a torpedo, he might want to take a bite back and cover the detonation depth to 15 meters. If it is, then the opponent must be forced down to the height of the periscope to ensure safety. In this era, submarines also have no active sonar... Hydrophones are also not so easy to use, so after diving to a depth of 20 meters, the submarine also knows nothing about the outside world.

The third one is here~~~! Please subscribe for a reward~~~!
