Chapter 1058
Liu Qiang led the Hu Ben Submarine Detachment to take the initiative to kill three Japanese submarines. The commander of the Japanese Navy's special mixed fleet, Ren Takenaka, was so angry that he sent all destroyers to chase the Hu Ben Submarine Detachment.
Plop! Plop!
After chasing the Japanese destroyers for more than ten kilometers, they finally captured the target. After setting the delayed fuze, the Japanese sailors began to push deep-water bombs weighing more than 200 kilograms off the deck.
Deepwater bombs have always been a standard weapon on anti-submarine ships in various countries. They are powerful, simple to use and very popular.
Deep water bombs do not need to hit the submarine directly, and the water pressure changes caused by the explosion are enough to tear the submarine's hull.
Therefore, deep-water bombs do not need to use trigger fuses, but use delay or pressure fuses, which require fixed-depth detonation.
However, although the power of the deep-water bomb is very strong in the water, it can be as powerful as a torpedo destroying the keel of a ship. However, the shock wave decays quickly in the water, and the explosion killing radius is not large. For example, the D-type deep bomb used by the British army is only about 22 meters.
A deep bomb can seriously injure the submarine within 20 meters, and it takes less than 10 meters to destroy it, so the timing and distance of the explosion are very high.
In the current era, the sonar system on destroyers is still very backward, and the sonar operation is distinguished by human ears.
As we all know, sound waves travel very quickly in water, about 1500 meters per second.
When the destroyer is less than 200 meters away from the submarine, the pulse wave emitted by the sonar is extremely close to the echo, exceeding the resolution limit of the human ear, making the two "bangs" sound combined into one, and the submarine disappears.
This leads to very inaccurate depth parameters, and the fixed-depth fuse error is very large when throwing deep water bombs, and the submarine can avoid many attacks by diving in time.
At the same time, the sonar has a blind spot directly in front of the bow of the ship, with a minimum discovery distance, and the down-tilt angle of the sonar beam is limited, which makes it impossible for the destroyer to discover when the submarine passes under the beam.
Therefore, anti-submarine ships can only blindly drop bombs at the expected waypoints, and they know nothing about the trends of underwater submarines, with poor accuracy and a hit rate of only 3%.
Therefore, in World War II movies, destroyers often throw a lot of deep-water bombs. They work hard for several hours, but the submarine is still shaking and escaping.
This is true in reality. Most submarines are destroyed by the accumulated damage of dense firepower for a long time, and not many of them are sunk in one blow.
For example, in April 1945, the German submarine U-427 suffered a bombing of 678 deep bombs and still survived.
This time, the Japanese destroyer, who had red eyes, could only use deep-water bombs to blindly bomb, and dropped sixty or seventy deep-water bombs at once and carried out large-scale net bombing.
Bang bang bang bang, after a moment, huge waves gushed out of the sea, and dull explosions were heard.
Fortunately, although the Japanese's operation was as fierce as a tiger, their final record was that they had not been collected.
Under the extreme operation, Liu Qiang and others avoided this wave of net bombing without any danger. Only two submarines suffered serious shocks, but only this was the case and did not lose their maneuver power and combat power.
"In the report, Lord Zuo, all 12 enemy submarines are alive and are continuing to escape to the coastline!"
After all the deep-water bombs exploded, the Japanese sonar operator immediately scanned and confirmed the results, but was sad to find that 12 submarines were still jumping around.
"Baga! None of the damn British submarines were blown up? Keep chasing them, and this time, throw all the deep-water bombs away!"
The commander of the Japanese Destroyer Fleet, Yoshihiro Iida, screamed in anger. This operation was really slap in the face.
At this time, a Japanese communications officer Koiwaigu Haki persuaded him politely: "Iida, we are already too far ahead and have entered the range of the China Shore Defense Cannon. If you continue chasing, you may be dangerous!"
"Xiao Yanjun, as an imperial soldier, how can you be greedy for life and fear death?"
Iida Yanghui's eyes were red, so why would he let the fat meat in his mouth fly away like this? He glared at Koiwai and shouted: "Execute the order immediately, and all destroyers continue to pursue! We must not let the Imperial Navy warriors die in vain! Hurry up!"
In addition to being eager to make achievements, Iida Yangqi is not completely mindless in seeking death, but has something to rely on.
Because although it has entered the effective range of the shore defense gun, the destroyer has a fast speed and a small target. As long as it is not very unlucky and a little back, it is difficult for the shore defense gun to accurately hit the target under normal circumstances!
"Hayi!"
The Japanese communications officer Koiwai did not dare to continue to fight, so he quickly took the order and left.
"Dog Damn is so arrogant. You dare to continue chasing us when you arrive at our territory! You pass me the order and aim for me! All the gun positions immediately fired and overturned all the Japanese ships of the dogma!"
Ou Hao, the commander of the Huben shore defense force, was observing the approaching Japanese fleet. After seeing the six Japanese destroyers break into the shore defense gun range, he issued an order without hesitation and firepower was fully opened.
In order to prevent the Japanese naval fleet from directly landing in Yangon, Yang Fan had spared no effort to strengthen military defense on the coastline around Yangon after entering Myanmar and built a very complete port and coastal defense system.
There are all 88mm anti-aircraft guns, 155mm secondary guns, 280mm and 305mm shore defense main guns. The cannons can support each other or support land fire, and can also guard against the Japanese Navy and Air Force.
There are also dozens of shore-proof torpedo launchers. If the Japanese Navy lands forcibly or hits the bombardment, it will definitely give the Japanese fleet a great surprise.
"receive!"
"clear!"
"Prepare! Fire!"
More than 30 large and small shore defense cannons roared all day long, and shells drew white bullet marks in the sky.
Bang bang bang bang, after a moment, huge waves burst into the sky near the sea of Madaban Bay.
Especially the 305mm howitzer, the waves blown out are simply overwhelming, and the sound waves soar into the sky. Even ten kilometers away, it can be shocking.
"Baga!"
"Diet, damn!"
Unfortunately, this round of fire-raising attacks did not directly hit the Japanese ship, but it caused great panic to the six Japanese destroyers rushing in the front!
"Baga! How could the Chinese army have so many shore defense artillery and are so powerful!"
A 305mm heavy artillery landed on the sea less than 30 meters behind the destroyer, and a huge wave more than 20 meters high exploded.
A huge sound came, and Iida Yanghui was shocked to his eardrums and his head buzzed.
Fortunately, this was at sea, and the old Japanese stood on a destroyer several meters above the water. Otherwise, they would have to die or be disabled!
Even so, Iida Yanghui was shocked by the shot that passed by.
Although the shore defense cannon cannot be like a torpedo, as long as it hits the hull, a small and medium tonnage ship like a destroyer can shoot a child at one shot.
