"Depth 7 meters! Continue to dive!" In the command cabin, a noncommissioned officer reported to Prienhui. At this time in the periscope, Prien finally saw how huge the enemy ship was.
"It's a Soviet-class battleship?" Prione muttered. He couldn't believe his luck was so good that he hit a Soviet battleship in the vast sea. To be honest, he did not want it to be a battleship, because wherever there were battleships, anti-submarine destroyers would them.
For any submarine captain, attacking a battleship in the theater is a risky act, because even with the final success, this submarine often has to face the pursuit of several destroyers immediately. It's one thing to get a medal. It's another thing to go back and get a medal.
Prion left the periscope, and the first officer joined to continue to observe the target. Captain Prien stepped aside, flipping through the projection records of the enemy ships. He wants to check whether the battleship in his mind is different from the real Soviet-class battleship image. The result made him very tangled. This is a Soviet battleship, and it is indeed the most famous new generation battleship "Soviet Class" in the world.
Speaking of the Soviet-class battleship alone, it may be the largest battleship in the world by far, with 9 large-caliber artillery pieces installed, and the layout is similar to that of Japanese Yamato. However, there is also a certain difference between the two. For example, the Soviet-class originally designed 406 mm caliber main gun (same as the Yamato class) was eventually imported into a 381 mm caliber main gun because of the difficulty of design.
However, the largest tonnage battleship built after World War I did not have radar installed, and the fire control system only used a relatively backward version. As a result, this class of battleship did not fully achieve the performance of World War II battleships. The strongest battleship in the late war.
After comparing, Prian put down the book in his hand, and then issued one of his own combat commands: "Dive down to a depth of 20 meters, prepare to release the torpedo to attack, continue to observe, and confirm the position of other enemy ships on the water."
"Tick ... tick ..." The echo of the sonar came from the headphones hanging on the ears of the German sonar soldiers, somewhat monotonous and hypnotic. However, the sonar soldiers still listened attentively to this sound. For him, this monotonous sound that seemed to never change was more important than the eyes.
He can tell the approximate distance between the submarine and the enemy ship from the sound, and can also hear whether the other party's heading is away or close. He could hear the sound of anti-submarine weapons falling into the water, as well as the explosion of the torpedo hitting the target. It can be said that under the water, he is the eyes and ears of the entire submarine, and is the only thing Prian relies on.
"Behind the battleship, there seems to be a destroyer! In addition, his silhouette is too large, I can't see another angle, whether its side wing is following more enemy ships!" The first officer reported his observations: " The boat that followed was indistinguishable, and was too far away. "
"Calculate the angle! Adjust the fixed depth of the torpedo. The preset depth is set to 9 meters! Quick!" Prien issued a new order.
The submarine ’s front torpedo compartment became busy, and technicians began to dial gears and valves to adjust the torpedo to a fixed depth. The depth of each torpedo adjustment is different. The depth of the explosion directly affects the degree of damage to the torpedo.
The closer the attack is to the bottom of the ship, the easier it is to cause greater structural damage. This has a lot to do with the seawater extrusion mechanics and the design of the ship. Usually the side of the warship is covered with thick armor, but the bottom of the hull is opposite. It is more fragile. Explosion close to the bottom can destroy more cabins, inject more seawater, and cause more trouble for maintenance.
Of course, it is impossible to set the depth of all torpedoes in advance. The ideal depth for attacking battleships is mostly more than ten meters. However, if this depth is used to attack destroyers or cruisers, the torpedo can only pass through the bottom of the other ship. Merchant ships are similar, except that merchant ships are usually very fragile, and a single torpedo is enough to solve the problem in most cases.
So most torpedoes are temporarily loaded and then fired. Pre-loading torpedoes in the submarine torpedo launch module only occurs in two cases: the first case is when the submarine captain is expected to launch the most torpedoes at the fastest speed For example, Prian raided the British port; the second case was that the submarine had just gone to sea and needed to carry the most torpedoes in a limited space for combat.
"The torpedo adjustment is complete!" The chief of the adjustment machinery adjusted the depth of the torpedo and quickly reported it to the command room. The command in the command room was filled without any pause.
"Loading!" With the sergeant's order, the four soldiers pushed the two torpedoes into the launch tube. The large torpedo launcher hatch was closed tightly by the soldiers, and then the two people worked together to tighten the valve on the hatch.
"Reload!" They adjusted four torpedoes, so after loading the two torpedoes, everyone did not idle, but quickly filled the other two, and soon the four torpedoes were pushed into the launch tube, while the other two In the launch tube, there are two torpedoes stuffed into it at the time of setting. The set depth is about 3 meters, not for the purpose of attacking the battleship.
At this time, the enemy ship was not far away from them. Prien, who had returned to the position of the periscope, confirmed the number of enemy ships through the periscope. In his periscope, there were 4 Soviet warships, one Soviet-class battleship, and one Unknown cruiser, there are 2 destroyers. This fleet is obviously going here to Leningrad, but it is ridiculous that it did not adopt the anti-submarine standard forward formation.
Have the opportunity! After this seems to succeed, there is still hope to escape! After thinking about it for a long time, Prien finally decided to take a chance. After all, such an opportunity is not common, and perhaps you will never encounter such an opportunity again in your life.
"Correction course! The course is 5 degrees to the left!" Prien wanted to get the best launch angle to ensure that after he successfully killed the battleship, there was still enough time to escape. After all, the two destroyers are not a decoration, and God knows whether the other will chase them.
"Prepare to launch the torpedo!" Prian was waiting, waiting for an opportunity. The bow of the submarine was already pointed at the other party's route. The torpedo can be launched directly without adjusting the angle. This is the most typical submarine attack, and the difficulty is also Relatively the lowest.
If the Soviet navy ’s destroyers used antisubmarine formations, it would be quite difficult for Prien to find such a perfect launch position, but it seems that the Soviets learned the British standard set of procedures, which will take a long time. time. Prien felt that it was necessary for him to give a lesson to the Soviets so that they could remember some knowledge that needs to be remembered earlier.
"No. 1 torpedo tube No. 2 to launch torpedoes! No. 3 torpedo tube No. 4 to launch torpedoes!" Prion didn't shoot out his four torpedoes at the same time. He paused for about half a second. At the time, he was turning slightly, so that his torpedo could cover a fan-shaped area about ten meters wide.
Waiting, all he can do for the rest of the time is waiting. The long waiting is enough to make people feel upset. Of course, you must find something for yourself while waiting, such as turning to escape and the like ...
"Steer! Left full rudder! Speed ​​4 knots, turn off the lighting in the boat, save electricity!" Priane gave the order smoothly, he was not only the first time to escape, he has already experienced the escape from the worse situation than today . So he is full of confidence now, because now this situation is just a "small scene".
On the sea that was originally full of broken ice, the white wave that was turned up by the torpedo was like four straight lines, extending forward from the original position of the submarine. It looked very obvious in the air, as if someone had drawn it at sea 4 The white lines are as clear.
In the advancing Soviet fleet, the chimney of the flagship Soviet battleship is emitting not very strong black smoke. The battleship is rushing to Leningrad at about the fastest speed, preparing to further threaten the coast of Norway and Finland.
The fleet commander felt that if he wanted to get rid of the threat of the submarine, then he had to increase the sailing speed. Once the fleet's speed exceeded 25 knots, then the submarine could not attack them. This conclusion was learned from the British, because the British statistical report writes this way, the higher the speed of the transport ship, the lower the probability of being attacked.
So this fleet of the Soviet Union so arrogantly put out the classic long snake formation, or the classic World War I formation headed by battleships. Prien was a little embarrassed to start with such a pure fleet commander, which for him is simply a two-meter-tall big man bullying the first grader.
At this time, on the lookout tower of the flagship USSR, the Soviet fleet, a Soviet naval officer frowned to see a distant and unidentified object moving on the water. At first, he thought it was a seal, but he Finding that the object moved too regularly, he picked up the telescope.
A periscope! He was stunned by the image in the telescope. It was a periscope that was turning away from itself. The soldier on duty quickly grabbed the phone: "Submarine! Starboard! German submarine! Attention!"
When he nervously reported his findings, he could already see the battleship's starboard side without four telescopes. There were four white water lines, which were quickly approaching.
He grabbed the phone and generally shouted in horror: "Torpedo!"
