The turbid air seemed to suffocate people to death. After two hours of submarine, I finally decided to ventilate. In the moment of floating up, Colonel Henry's heart, if the submarine could never float up, then how good would it be. Even if there were more planes to drive now, this idea can only be a luxury and can never be realized.

The blue sea water slowly turned into thin transparent sea water. The submarine finally floated onto the surface. Someone couldn't wait to open the hatch cover. A long-lost fresh air floated in, awakening the beautiful memories in everyone's heart. Everyone was breathing in big mouths. Except for the face.|

"Enemy planes, enemy planes, dived up and down. In fact, since he floated up from the sea, the fate of this submarine was destined to be unchanged. Some American naval soldiers rushed into the hatch in panic. Some bold ones rushed to the deck cannons. However, the raptors in the sky did not give these people a chance. Four 38-meter machine guns began to roar, forming a series of flames. They swept these people in. When the smoke of the gun disappeared, these people were torn to pieces together with the deck cannons. After clearing these little troubles, the big wave of beauties was sexy in their arms. Of course, there was no one: _Banana. Meng Jianhong's level of yy already|.

"Kill all these bastards and throw them down to the submarine. The fragile anti-pressure shell was torn apart countless pieces. The sea water rushed into the gap. In less than three minutes, the +000 submarine sank into the seabed.

Colonel Henry was still struggling. But after all, people are not fish. Only. Colonel Henry's hands and feet became stiff. The experiences in his mind began to take place like a lantern. It slowly turned gray, black and white, and finally fell silent together. In this way, the submarine sank into the bottom of the sea and became an amusement park for fish and shrimp in the deep sea.

This attack. The Americans suffered heavy losses. Half of the submarines involved in the ambush were injured. The results were very poor. Only 7 merchant ships were sunk. The tonnage of the sunk was not much different from that of the sunken submarines. In this case of loss, the Americans did not. Frequency. It turned out that this was an effective tactic. The Americans handed over the submarines, but the effect on the blockade was much worse. Due to the relatively sufficient supply, the Expeditionary Force slowly reversed the decline. In this case, anti-submarine combat and submarines were all mentioned to an unprecedented height.

"The Pacific Battle has always been the dominant factor in the smoothness of the Expeditionary Forces. I cannot forget for a moment that everything happened on land, in the ocean, in the sky or anywhere else was ultimately closely related to the outcome of the Greater Pacific Battle. That terrible place, uninterrupted journey of suffering - full text novel reading, at www.piaotian.com.com (piaotian...cn.wen.Study Network - I am often in extreme dilemma and setbacks, and always face invisible dangers. I eventually walked on the road of light by chance and dramatically." And specifically pointed out that the only thing that really scared me in the war was the submarines of the US Navy!

Excerpted from the memoirs of Marshal Han Xinghua

This is indeed the case. After entering the United States, American submarines have always been the main threat to Britain. The strategic height that this naval tactic reached in World War II was not comparable to that battle. Compared with the heroic battleship confrontation, the battles in the Pacific were less brilliant and masculine. However, they were always filled with a mysterious and gloomy atmosphere. "Wolf packs" appeared in the Pacific, and submarine warfare and anti-submarine warfare ran through the entire war. Strictly speaking, it was not the same.

The second naval battle is a protracted maritime war, composed of countless battles and battles, with countless successful battle examples. What made the great Chinese Empire feel the pain of failure. It is only the US submarines' battle against maritime transportation. When the US submarine activities, known as the sea wolf, were most rampant, almost cut off the Pacific route that was crucial to China, and almost firmly strangled the throat of the Imperial Expeditionary Force! It made China feel the pain of failure at a close distance!

In order to better attack American submarines, the Royal Navy, which was inflamed, put forward basic requirements for new anti-submarine weapons: launch from the head of the anti-submarine ship; the spread area should be large to increase the probability of destruction. Deepwater bombs are ready-made, and MK-type deep-water bombs are fired in front, but these deep-water bombs are all big guys of hundreds of kilograms. If converted into the caliber of the same weight, they must at least be

In addition, the recoil generated by the launch of medicine is said to be that the deck structure of small ships cannot even medium-sized ships. Moreover, this deep-water bomb cannot sink very quickly vertically.

Besides, when it comes to using a deep bomb of several hundred kilograms, there are a lot of bottles and jars. It’s okay to put the ship at the stern, but it’s the main force of anti-submarine. The strict requirements made this new equipment difficult to produce. In the end, the Navy had to publicly bid for the development of weapons. As expected, not long after, a weapon development department of the Army, the Supercaliber Mortar Team, accepted this challenge. Previously, this group specially developed supercaliber artillery.

Supercaliber mortars were launched in the early 20th century and flourished before the 20th century and 20th century. Especially before and after World War I, it was the most powerful influence. It is known as the "trench warfare treasure". However, during World War II, the shortcomings of this weapon broke out and disappeared. The reason is very simple. Although it can fire powerful shells, its range and accuracy are too poor. Especially in terms of range, it is too far from the level of the times. In addition, the mobile combat form gradually replaced trench warfare. The shortcomings of the inconvenient carrying of supercaliber mortars are becoming increasingly obvious. Therefore, the supercaliber mortars gradually gave way to modern mortars (standard caliber mortars).

If it weren't for this tender, then there was no doubt that these people would have been put on. So they cherished this unexpected opportunity very much. So soon this...

Diameter: 0mm Weight: 29 kg/charge 15 catties 0-259 meters 6.7-7.2

Of course, if you just look at an indicator, this is nothing great. However, there are 24 gun barrels on the launch frame, which are tilted forward by 45 angles. So many gun barrels are leaning together, like hard thorns on the hedgehog body, so they are named, very vivid. The launch frame of this hedgehog bullet is usually installed on the front deck of the boat or the front end platform of the first upper building. It is placed on a metal insertion rod, and the shell of the launch tube is placed outside the insertion rod, which plays a similar role to the gun barrel;

The projectile body is controlled by the circuit to launch two bombs each time, with a distance of 0.124 hedgehog bombs one by one at a short interval. It can form an oval barrage with a radius of about 130 feet more than 200 meters away from the front of the ship. The boat can explode, and the vibration caused by one explosion causes the remaining 23 explosions.|In the fire net. In fact, two shots are generally hit directly to ensure the sinking of the submarine.

Compared to deep water bombs,

1) Because of the use of trigger fuses, sonar; and the explosion of a deep water bomb takes 15 minutes to basically ignore its interference and escape for more time;

—

2 There is no need to know the accurate depth of the submarine. It is also because of the use of trigger fuses. This is a headache for using deep bombs. The submarine is also constantly maneuvering vertically. In the early stage, the error of the deep bomb is relatively large. If it is set to 100, it will explode at 50 meters. It is useless.

3. The submarine will not be found and attacked. The attack of deep-water bombs is very obvious to the submarine. It seems that entering and sinking will make special sounds, which are easy to distinguish. Of course, the submarine will also have a warning time.

4 Compared with deep water bombs, the hedgehog bomb is very light, and small ships can be equipped without additional reinforcement. The hit probability is also increased, and the probability of hitting a submarine reaches 8. Although it looks very low, | and promises to put all efforts into production.

After equipping new weapons, the loss of American submarines increased significantly. They sank 1/4 in just one month. This loss forced the commander of the US submarine force to issue orders. ~. Less attack frequency. But this approach is to make China's fortune.
