Another 40 minutes later, these five targets suddenly disappeared from the radar. At this time, the federal submarine that went to search the target sea area was still about 10 nautical miles away from the target. The sonar device on the submarine did not find any abnormality, so it could only return. However,
This situation has caused the Pacific Fleet to
Note that a few days ago, one of their naval supply ships was sunk by a torpedo in the south of Taiwan Island, and the ship that launched the torpedo was probably a submarine. The Navy Department has issued an order, and all four federal fleets have
Begin to closely monitor your own jurisdiction to prevent similar incidents from happening again.
Judging from the performance, these five radar signals are likely to be five submarines. They dived before approaching the strait, and they were probably planning to cross the strait and enter the Celebes Sea. If it were placed 5 years ago, this would have been
The five submarines might have actually gotten through, because that was because the Federal Navy did not take strict precautions against submarines. Because at that time, except for the South China Sea Federation and Germany, there was no large-scale development of submarines in the world, so the maritime defense operations at that time were
The main target is surface ships.
However, as the federal government severely damaged the British and American navies and sold off a large number of decommissioned submarines, the world's naval powers have begun to step up the research and development of submarines in recent years. The United Kingdom, the United States, Italy, the Netherlands, Chile, the Soviet Union, Japan, etc.
The capital has successively established submarine forces and schools.
, this forces the Federal Navy to include anti-submarine warfare in the terminal defense project. Now the Federal Navy has two main anti-submarine means. One is destroyers and minelayers equipped with sonar devices, and the other is submarines, especially killer whales.
-class submarine, it was originally designed to deal with submarines.
The Pacific Fleet was not in a hurry to send a large number of anti-submarine ships to the strait to intercept these suspected submarines. That would probably alert the enemy and make them escape. It would be very troublesome to find them again. They planned to close the door and beat the dogs.
These enemy submarines
Lure the submarines into the west side of the strait, and then block the strait so that they cannot escape into the Pacific Ocean. In this way, these submarines can only toss in the Celebes Sea. The current anti-submarine capabilities of the federal navy are enough to survive in this small area.
Catch these small fish in the sea.
The five targets on the radar were none other than the Japanese submarine squadron led by Noriichi Kawasaki. They had just acquired surface ships near Palau in the afternoon, and then arrived at the east side of the Celebes Sea after dark.
Before setting off, Huashan Jiyi carefully
I have studied the map of the South China Sea Federation. He found that if you want to enter the territorial waters of the South China Sea Federation, there are only two places that are easier. One is to go west along the coast of China, all the way to Hainan Island, and then turn to the south. The other is to enter directly from the Pacific Ocean.
Celebes Sea.
The first route is relatively close. However, there are many ships on this route, and there are also many islands and reefs. The Lu-23 submarine has only about 10 hours of submersible time. It cannot sail underwater throughout the day and must float up to recharge.
Angry, this way the whereabouts will be easily discovered.
The second route is relatively far away, but there are no commercial routes here and there are very few ships. It is more suitable for submarines that need to be hidden. As for the defense of the island chain here, Kaguyama Kiichi is confident that he and the crew can rely on their outstanding performance.
Use your navigation skills to avoid these obstacles.
According to the previously formulated plan, Kaguyama Kiichi and his submarine team entered a submersible state 20 nautical miles away from the entrance of the strait. The five submarines lined up in a straight line, half a nautical mile apart, and slowly moved into the strait. Starting from
The submarine is
It is the No. 9 boat of Kiichi Kayama. It is traveling at the height of the periscope. Kiichi Kayama is lying on the lens of the periscope, carefully observing Sarangani Island on the north side of the strait, where is a member of the Federal Navy.
It is an important coastal defense site with shore guns and searchlights.
It was already late at night, and the strait was dark and quiet. Only the searchlights on the island were turning in regular circles, and not even a patrol boat appeared. Kashan Noriichi did not rush in rashly, but
After observing the outside of the strait for another 30 minutes, and after confirming that there was no danger, he entered the strait at a slow speed. Behind him, four Japanese submarines followed closely behind his stern and entered the strait.
The dull half hour finally passed, and Kaguyama Noriichi breathed a sigh of relief. During this half hour, everyone in the submarine held their breath and stopped moving. Even the crew members who were sleeping during the shift
Being woken up because of snoring, the sonar soldier on the boat wanted to put the earphones into his ears, and concentrated on searching every syllable from the earphones to make sure that both the water and the surface were safe.
"Rumble...Rumble..." Suddenly, the sound of the ship's engine came from the sonar soldier's earphones. This made the sonar soldier's hand suddenly shake, and the earphones almost fell off. He quickly pressed it hard again.
Press the earphone to make it fit more closely to your ears, and then turn the pointer on the instrument.
"Your Excellency, General, these are destroyers, four of them, behind us." A few seconds later, the sonar soldier reported his findings in a low voice to Noriichi Kayama who was lying on the periscope.
"Baga!!!" Nori Kayama suddenly started to move again. He turned the periscope and looked behind the submarine. Through the periscope, he could vaguely see two black figures, which were lit up.
Navigation lights, heading towards the middle of the strait.
"They didn't discover us and didn't pursue us," the sonar soldier added.
"But why did they come out suddenly? And there were 4 ships at once. This is not normal..." Kashan Noriichi was still very sensitive, as if he had sensed some danger.
"Your Excellency General, we have also spotted a destroyer in front of us. We are surrounded..." The sonar soldier suddenly stood up from his seat and shouted in panic.
"Baga!!! What are you shouting for? Keep observing..." Huashan Ji turned away from the periscope and stared at the sonar soldier with wide eyes.
"Put away the periscope and dive to 40 meters..." Huashanji turned the periscope another 180 degrees and looked directly in front of the submarine. He issued an order and then rushed to the chart in one step.
"Open the forward water tank... prepare to dive..." The navigation chief followed the captain's order and shouted out the operating procedures. The alarms in the submarine lit up, and all the personnel on duty tightened their grip on the fixed objects around them.
"This is a trap, we are surrounded, I hope the Emperor protects us..." Nori Kayama looked at the chart, leaned slumped on the chart table, and said to the captain, his face was filled with confusion.
He was pale and large beads of sweat appeared from both sides of his forehead.
"General, we still have a chance. Now turn the helm and leave the channel at full speed, and then sit on the bottom of the sea. The water depth here is only 60 meters. We may be able to survive!" The captain saw Huashan Ji at a loss and shook him anxiously.
shoulders.
"You're right, let's give it a try and go full speed with full left and full rudder! I hope Miyafuji and the others also find out." Noriichi Kayama woke up from the momentary disappointment.
Submarine No. 9 suddenly accelerated underwater and rushed out to the left side of the channel. At this time, several destroyers approaching from the front could already be seen with the naked eye. They turned on the high-power searchlights on the ship and illuminated the sea.
There was a bright light, a periscope more than 1 meter high above the sea, standing alone in the water, like a big target.
The destroyers seemed to have seen their prey, and they turned on full power and rushed towards the periscope at full speed. At the same time, the vibration of the high-power engine and the sound of the propeller made the sonar soldiers on the destroyer extremely anxious because they could not hear it.
The sound of submarines under clear water was heard, and at too close a distance, it exceeded the radar's resolution.
"Plop...plop...plop..." A string of depth charges were pushed into the seawater from both sides of the destroyer's stern like dumplings. Half a minute later, with bursts of dull sounds, the seawater was
The powerful explosion pressure lifted up from the sea surface, forming water columns more than ten meters high one after another.
The periscope on the second-ranked Japanese submarine and the immature anti-submarine technology of the Federation Navy saved Noriichi Kayama and his No. 9 boat. Taking advantage of this violent explosion, his submarine opened at full speed.
He increased his horsepower and rushed out of the encirclement at the highest speed.
Circle. Due to the continuous sound of explosions, the sonar soldiers on the destroyer were no longer able to conduct hydrophone operations, and the radar could only scan water targets. No one noticed the submarine that slipped away quietly. (To be continued.
