Chapter 887 Deep Bombing (Plus, Ask for a Monthly Ticket)
In later generations, there are many TV dramas and movies that describe the spectacular world war and submarine warfare movies.
In order to attract the attention of the audience and create a gripping and tense atmosphere, there is a section in which the submariner cannot speak loudly on the submarine. As a result, a coin is accidentally dropped.
And the most amazing, the other party's sonar operator actually heard whether it was face down or back down. This definitely belongs to the category of divine drama.
In this era, of course, it is impossible to happen. Even in later generations, sonar technology is already quite advanced, and it is impossible to reach this level.
Sonar technology has actually been around for a long time, much earlier than radar. After all, sonar is equivalent to receiving sound and amplifying it. Simply put, isn’t that what the microphone achieves?
However, if you want to use it on submarines, this large microphone must be more refined, and at the same time, the amplification ability must be as powerful as possible.
For example, on this island country submarine, it is equipped with the latest Type 93 hydrophone developed by the island country. Yes, it is not called passive sonar now, but it is still called hydrophone. The name is more vivid than sonar.
As for its effect, some data say that it can only be heard at a distance of about 100 meters? (Huadong Zhixiong is not sure, I hope someone who knows it will greatly clarify the doubts.)
Sailor Kotoro Rokuro has a large black earphone on his head. In front of him, the cathode ray tube is also erratic.
Suddenly, he frowned, and his face became extremely pale: "Captain, I heard the sound of depth charges falling into the water, um, there are still a lot of them!"
"Dive, continue to dive!" Guitouyansan ordered.
Right now, they're traveling underwater at 3 knots, which allows them to use their precious electricity for longer, with the downside of not being able to get out of the water quickly.
And now, the anti-submarine depth bombs one by one indicate that the opponent's interception force has arrived!
Up to now, all the scumbags are wondering, why do these Americans want to beat them up when they catch them? Haven't they clashed with the Americans?
"Boom!" At this moment, an anti-submarine deep bomb exploded in the water above his head. This huge sound made Kotoro Rokuro close his eyes in pain and forcefully took off his earmuffs.
He felt that his ear was about to bleed, and there was a rumbling sound inside. This is definitely not a good experience. If you don't believe it, how would you feel if you magnify the sound of the shell explosion a hundred times to your ear?
The sound is very loud. This bomb exploded near the submarine. The sound waves slapped against the outer shell of the submarine. For the cavity of the submarine, it has a cavity effect that amplifies the sound.
Hiding in a submarine will not feel safe.
"Dive down, continue to dive!" Guitouyasan is still experienced. Although the sound of the explosion is terrible, it will not cause harm to the submarine.
It is not terrible to hear the explosion, but it is terrible to hear the sound of water under high pressure, because it means that the submarine has broken a big hole!
Under his orders, the submarine began to tilt.
The propeller at the tail turned slowly, the hull of the submarine tilted, and the head end moved towards the deeper sea.
"Set the depth to 100 meters." Guitou shouted.
His words made others tremble immediately, and the helmsman in charge of the operation turned his head and looked at him with uneasy eyes.
This Haid 6b submarine is improved on the basis of Haid 6a. The improvement is to increase the diving depth and increase the voyage.
However, even if it is increased, there are limits. For example, the designed diving depth of this submarine is only 85 meters.
In the ocean, sea water pressure is a terrifying enemy. Every ten meters of diving, the pressure must be reduced by about one atmosphere. The pressure hull outside the submarine is limited. If the designed diving depth is exceeded, God knows what will happen.
"Execute the order!" said the ghost.
As an old submariner, he was clear at this point.
The design diving depth is the designed diving depth, and the actual diving depth is the actual diving depth. When designing, there is a margin.
What's more terrifying is that his submarine can't outrun those terrible enemies on the water, even if he sails at a speed of 3 knots, up to 65 nautical miles, it will reach the limit.
Once the battery is exhausted, he needs to surface to charge the battery. At that time, can he still run away?
This attack is too strange. He needs to persevere until the high-level side has action. This is his hope of being rescued.
Is there anything more important than adding depth?
The ghost-headed three also have no choice.
The submarine was sinking slowly, and the helmsman looked at the depth gauge, sweat dripping from his back.
Finally, at 95 meters, he began to slowly level off, and eventually, the submarine stabilized to a depth of one hundred meters.
"It has already dived to 100 meters," said the helmsman.
Picking up his earphones again, Kouto Rokuro continued to listen to the sound inside, and at this time, the sound had become smaller.
"The depth bullet still exploded at a depth of 20 meters, which has no effect on us." Rokuro Koujiro shouted.
If it is on a warship, it can be adjusted at any time when the warship is encircling and suppressing the underwater submarine, and it can be changed at any time before the anti-submarine depth bomb falls into the water.
However, the depth bombs carried by the aircraft will not work, and no pilot will do aerial acrobatics, walk to the wings or belly to readjust, and it has been determined when it is mounted.
The small bombs on the wings have a fixed depth of twenty, while the large bombs under the belly have a fixed depth of one hundred.
This is tailored according to the German submarine. If the German submarine is at the depth of the periscope, then 20 meters is just right. If the German submarine dives, their diving depth is more than one 100 meters, set to 100 meters, relying on the power of the big bomb, it can still be blown up.
When the first coverage bombing was completed, all the planes had risen, leaving only the seaplane, still observing.
If the submarine below is bombed, there will definitely be a louder explosion, there will be oil stains, and corpses will float up, so that the victory can be confirmed.
The Kingfisher reconnaissance plane circled the sea and flew round and round. Chris and Schroeder repeatedly observed the sea and found nothing unusual.
"That submarine must be hiding underneath!" the bomber's captain shouted, "Prepare to drop a big bomb!"
The small bombs have been thrown, and now, there are only the big bombs left. Since nothing was blown up, let's go to the big ones!
In the sky, the dreadnought bombers lined up in formation again and dived down.
