The sniper starts from the bright sword escape period

Chapter 252

Of course, the Bailixiu before the crossover naturally became one of the people who went to buy the fish caught by the master fish catcher in the farmhouse.

I spent 20 yuan to buy a fish that weighed a few kilograms, and when I got home, I said that I caught it with all my hard work.

So Bailixiu was naturally envious when he saw Wu Wanli catching fish with his bare hands in the water easily. He thought that if he could learn Wu Wanli's skills, and if there was a possibility of going back that day, then Bailixiu I must visit that farmhouse again and become such an expert fish catcher, and then stay in that farmhouse every day to catch fish and sell them.

Of course, this is just Bailixiu's thinking. The most important thing now is to train the frogmen to complete Bailixiu's task of advancing to the silver level.

After all, Bailixiu's silver-rank promotion task is to kill the warships or aircraft carriers of the Mi Army!

The time for training is always relatively fast, and another month has passed in the blink of an eye, but at the end of this month, the assessment of who belonged to the fifty underwater frogmen ushered in.

It's just that Bai Lixiu has added another item to the diving speed and endurance assessment, that is, the diving depth is also assessed.

But what Bai Lixiu didn't expect was that the newly added diving depth assessment immediately revealed the gap. The 30 people in the entire interspersed battalion can dive to the depth of 1 meters and stay at the bottom for [-] minute. There were only sixty people.

So needless to say, the frogman special team was born among these 60 people naturally.

Bailixiu used ten of them as reserve personnel to train with the other 50 people.

After selecting these 300 people from the 60 people, Bailixiu began to let the 60 people how to use compressed air cylinders to breathe underwater, and how to practice underwater pistol shooting, and of course the last Flipper adaptation and the placement of underwater bombs, but the placement of underwater bombs is actually the easiest.

You only need to swim to the bottom of the battleship and press the magnetic bomb, and finally press the countdown button to finish and run away.

However, the location of the underwater bombs is particular. In order to achieve a one-hit kill effect, the underwater bombs must be placed in the weakest position of the entire battleship.

As for general warships, the weakest position of an aircraft carrier is naturally the middle position at the bottom of the ship.

Placing underwater bombs in this position will easily blow up the entire battleship by two sections, making it impossible for ship repairers to repair it.

And why Bai Lixiu taught the frogman special forces to plant underwater bombs in this way is naturally learned from the torpedo combat method.

You must know that the general torpedo attack does not hit the target. Once it hits the target, the target warship can be thrown from the water surface directly, and the keel will break. Therefore, the surface warship under the torpedo attack will be broken into two pieces when it is smaller, and a large hole will appear underwater when it is larger. The damaged tubes cannot be repaired, and they will sink soon.

In addition to the larger the torpedo charge, the greater the explosive power, the more important thing is that the attack method is different for torpedoes and aerial bombs, which is the biggest difference. Aerial bombs attack above the water surface, while ordinary explosives explode The damaging shock wave and high-temperature and high-pressure gas spread to the surroundings, causing the failure of various subsystems inside the ship. If it enters the ammunition depot and detonates the ship’s ammunition, it will be sent to the soul. This is shit luck, because the ammunition depot of the battleship will not above the water.

There are a lot of redundant backups for each subsystem of the battleship. If the damage control is effective, even a few [-]-pound aerial bombs may be saved!When the torpedo attack does not hit the side wall of the battleship as imagined, it will set a depth and pass under the keel of the battleship. When the magnetic induction detects the warship, the fish warhead explodes!

Water is incompressible, so an explosion in the air will form a shock wave that spreads differently. An underwater explosion will perfectly transmit energy to the hull. A huge explosion can directly throw the hull up, while warships and aircraft carriers are often made into slender shapes. Reduce wave-making resistance, and this type of ship is most afraid of huge waves whose wavelength is exactly equal to the length of the hull, because this kind of wave will cause the two ends of the ship to tilt up and the middle to sink, which is equivalent to breaking the hull. Suspended in the air, causing a great bending effect to the keel.

The explosion of the torpedo under the keel is to cause this effect. The cavitation generated by the underwater explosion will compete with the water pressure to form bubble pulsation. Simply put, the huge cavitation will expand, and then the underwater It contracts, expands, and compresses, moving towards the surface of the water in the process!
At this time, the hull will also be stretched and shrunk, and the keel will be bent repeatedly, but it is more likely that the keel will be broken when the hull is thrown up for the first time, so the torpedo attack is almost a hit!
And Bai Lixiu placed the underwater bomb in the middle seat of the battleship or aircraft carrier, which can naturally have the same effect as the torpedo.

It's just that what makes Bailixiu a little headache is that when Bailixiu explained to the newly selected members of the frogman special team, Wu Wanli, a curious baby, always raised his hand to ask questions. For example, when Bailixiu just explained After finishing why the underwater bomb should be placed in the middle of the battleship, Wu Wanli raised his hand and asked:
"Coach Baili, is this really the case? Putting the bomb in the middle of the battleship can really blow the battleship into two sections? What if it can't be blown into two sections? Do you want to put the bomb at the tail of the battleship to reduce the power of the battleship?" The propeller is blown up!"

Bai Lixiu looked at Wu Wanli in disbelief, and even wanted to change the way Bai Lixiu bombed the battleship, so he couldn't help but feel a headache.

However, Bailixiu felt that the truth could still be found in practice, so she said to Wu Wanli:
"Since you don't believe it, let's do an experiment to test whether what I said is right! Is it better to blow up the middle of the battleship, or blow up the two ends of the battleship!"

And Wu Wanli said after hearing Bailixiu's words:

"How to try, there are no battleships here! You can't get a small wooden boat to test!"

However, what Wu Wanli did not expect was that Bailixiu nodded and said after hearing what Wu Wanli said:

"That's right, we just got a small wooden boat to test, to see if it's more powerful to blow the stern or the middle of the boat!"

Sure enough, Wu Wanli heard that Bailixiu actually wanted to get a small wooden boat to test it out for himself, so he immediately said:
"Okay! We happen to have a lot of small wooden boats here, so let's just bring one over here for experimentation!"

Of course, Bailixiu had no doubts about Wu Wanli's words, but Bailixiu naturally paid for it. After all, these small wooden boats are the food of local fishermen.

However, these small wooden boats, which are only five meters long and one meter wide, are naturally cheap because they are easy to manufacture, so Bai Lixiu immediately bought two for experimentation.

Moreover, Bailixiu also discovered that the small wooden boat in Wu Wanli's house is quite unique, and it even has a waterproof cabin.

That's right, several boards were erected on the side of the small wooden boat to divide the originally integrated cabin into several sections, so that even if a section of the cabin leaks, as long as the load is not too much, it will not sink immediately.
