Chapter 1,296 Wolf Pack Attack
Chapter 1296 Wolf Pack Attack
"You can attack." Dönitz gave the order to attack. "After the second attack, dive quickly."
A few seconds later, with the action of high-pressure air in the torpedo tubes, the covers of the three torpedo tubes located at the bow of the boat were popped open, and three torpedoes weighing more than one ton jumped into the water. After a while, they were driven by the heat engine. The torpedo engine started, and streams of exhaust gas were expelled from the torpedo body, forming a white trail underwater.
They were equally unprepared. The submarines U190 and U154 launched their attacks at almost the same time. Before the Japanese fleet received the warning, the No. 1 target ship in front was blown into pieces by two torpedoes. , a huge fireball rose on the sea, and the power of the explosion was far greater than the power of the two torpedoes. It seemed that this time it hit a ship transporting arms.
The dazzling light illuminated the surrounding sea area as if it were daytime. Dönitz subconsciously opened 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 attack!" Dönitz ordered.
The U190 submarine turned 15 degrees to the right, and the torpedo tube on the rear side was aimed at the second transport ship. At a distance of 1,000 meters, while the other ship was still looking weak, two torpedoes quickly rushed out. No matter what, blow up the opponent's face!
"Prepare to dive, start counting down!" Dönitz just wants to leave quickly. Something unexpected happened to the first target he just attacked. The sudden bright light is very likely to reveal his position. Now, he needs to dive quickly. , leaving the battlefield before the Japanese could react.
But perhaps Dönitz had been too successful before. According to the law of conservation of RP, God thinks it’s time to give you some hardships. At 4,000 meters behind the U190 submarine, the Japanese destroyer Hatsusho discovered this guy who killed him at night! And just as Dönitz feared, the destroyer found Dönitz through the fire when it exploded on Target No. 1!
"Artillery fire, prepare depth charges! Let's kill this guy." The angry roar of Nagumo Chuichi, who served as the captain, resounded throughout Cambridge. Ten seconds later, three 120MM shells landed around the U190 submarine.
Thanks to Dönitz being vigilant enough to dive immediately after firing the torpedo, when the destroyer Frost determined the location of the submarine U190, only a small half of the U190's control tower was still above the water!
After three rounds of shells were fired, naturally nothing was found. However, Chuichi Nagumo did not intend to give up just like this. For the destroyer Hatsusho, which has a top speed of more than 30 knots, the distance of more than 4,000 meters is only a few minutes. When U190 is completely hidden under the sea, the destroyer Hsushuo is We have arrived near the location where U190 dived before!
"Turn on all the searchlights,
Everyone, pay attention to the sea, there may be torpedoes in the torpedo tube of this submarine! Depth charges are prepared to set the depth. The 10 rounds in the front set the depth at about 15 to 25 meters, and the depth in the back ranges from 35 to 45 meters! Prepare for anti-submarine warfare! "Second Lieutenant Nan Yun ordered.
How to fight anti-submarine warfare against destroyers in World War I? In this era when active sonar is not widely popularized and hydrophones can only be used make-shift, there is only one weapon for anti-submarine warfare, which is coverage bombing with depth bombs. As for how to discover submarines? Most of them were naturally discovered after the submarine surfaced, such as the U190 just now. It is still difficult to rely on hydrophones and sonar to detect submarines. It can be said that more than 60% of the difficulty of anti-submarine warfare lies in the search. But now, although the difficulty is only 40%, it is still difficult to handle. Otherwise, the wolves in the first battle will not be so intimidating.
Generally speaking, Nagumo Chuichi is still capable, otherwise he would not become a general! In just a few minutes, he straightened out the whole story. When the first target was destroyed, there were at least two big explosions, so it was very likely that two torpedoes were hit. After that, the second When the target was destroyed, it also exploded twice, and it should have hit two torpedoes. In this case, the German submarine fired at least 4 torpedoes. How many torpedo tubes does a submarine have? Usually there are 6 at most, 4 in the front and 2 in the back. Based on the positions of the two transport ships, Nagumo deduced that the submarine should have used its front and rear torpedo tubes at the same time to complete this double kill!
"This guy is such a talent." Although he was an enemy, he attacked two targets at the same time in less than 3 minutes and succeeded. Na Yun had to express his admiration in his heart!
Well, if my estimate is good, then the number of remaining torpedoes on this submarine will never exceed 2! In other words, the shark that had just finished feeding should be in a period of weakness. The opponent's attack power has been reduced to a minimum. If the torpedo tube needs to be reloaded, it will probably take about 20 to 40 minutes! So when launching an attack at this time, the destroyers on the water will obviously have the advantage!
Underwater, the speed of a submarine is generally 4 to 5 knots, which is the most economical speed. This also means that the speed of a submarine moving underwater is actually not as fast as riding a bicycle... Therefore, in this combat situation, Nagumo Chuichi has a high probability of destroying his opponent through a depth bomb attack.
Never underestimate the power of depth bombs. Take the Japanese Type 88 depth bomb as an example. The charge is 148KG and the detonation depth is 15 to 25 meters. If the submarine is within the explosion distance of 150 to 250 meters, the damage will be Almost not. If the explosion distance is within 50 to 100 meters, it may cause a certain degree of damage to the submarine, such as moderate water seepage at the rivets of the submarine shell. The battery pack may be damaged. If it is close to 19 meters, the submarine will have a large area of water intrusion, and the valves inside and outside the submarine will also leak seriously. The battery pack will be severely damaged, and it is even possible that it will not be able to submerge. If it explodes at a distance of 10 meters, then good, I wish you good luck along the way. The inner and outer shell of the submarine will be directly destroyed, and the submarine will hit GG!
Nan Yunzhong was also very particular about the settings of the pair of depth bombs. He set the detonation time earlier because the submarine had just dived, and if the opponent had a torpedo, he might want to bite back and cover the detonation depth to 15 meters. If so, then the opponent must be forced to descend to the height of the periscope to ensure safety. And submarines in this era also did not have active sonar... Hydrophones are also not that easy to use, so after diving to a depth of 20 meters, the submarine knows nothing about the outside world.
