Chapter 244 The Underwater Equipment of the Frogman Special Forces
After the frogman soldiers of the No. [-] team came ashore, they took advantage of the chaos and fled the port of Alexandria. They planned to find another ship in other ports and return to Italy.But before that, they plan to have a meal at a nearby restaurant.Due to the strong Italian accent of these two people, combined with the explosion that happened in Alexandria just now, Yinjun quickly arrested the two frogman soldiers in the restaurant.

What happened to Team No. [-] added a touch of humor to the entire Alexandria attack.

At this point, the Alexandria attack officially ended.The Yin Army lost two large battleships, a tanker, and several cruisers were severely damaged.As for the Italian army, only six frogman soldiers were captured.

Such an exaggerated battle loss ratio can be called a miracle in the history of World War II, and it is also the most proud record of the Italian fleet in World War II.

Of course, if the first two groups of six frogmen did not leave in a hurry after installing the bomb, but were the same as the third group of frogmen, maybe Yinguo would not know why his ship was bombed, and it is even very possible He would suspect that there were spies and traitors among the soldiers who manipulated the fleet.

Of course, if it is more exaggerated to say that the frogman has not been discovered, then the history of World War II may be rewritten.

No way, this is too exaggerated, six people killed two battleships, what a record!
Of course, the little devil was also inspired by this influence, and created the "Fulong Special Attack Team" in the latter part of World War II.However, due to technical limitations, the equipment of the "Fulong Special Attack Team" was too heavy underwater, resulting in very weak mobility. After dozens of "white mouse" soldiers suffocated to death on the seabed, the little devil's frogman soldier plan died prematurely.

And this kind of frogman special force, which can be produced without too much industrial strength, naturally meets the needs of the tide aid army.

If the Tide Aid Army has such a special frogman team, then the fleet aircraft carrier of the Mi Army will no longer dare to stop at the port at will to bombard the Tide Aid Army.

And this frogman special team is obviously not suitable for Bailixiu's silver-level promotion task.

However, when training the diving ability of the special frogman team, there are naturally very strict requirements for the equipment of the special frogman team.

At least if you want the frogman special forces to blow up the fleet aircraft carrier, then you must complete the three major pieces for the frogmen.

The first piece of equipment is the equipment for the frogman to swim underwater. No matter how much the frogman trains, he is still inseparable from the human category, so no matter how good the water ability is, no matter how talented the person is.

It can hold its breath underwater for no more than 5 minutes. Although Bailixiu's world record of holding her breath before crossing is more than 20 minutes, don't forget that this is not the kind of record that can't move after holding her breath. up.

Instead, they had to parade underwater to plant bombs at the bottom of the ship, which naturally led to a huge increase in oxygen consumption.

So you must prepare a high-pressure gas cylinder that allows frogmen to dive underwater for an hour or even several hours.

Of course, this high-pressure gas cylinder cannot be manufactured with the current manufacturing capacity, after all, there are no blueprints for how to manufacture it.

Fortunately, Bailixiu had been swimming for a while before crossing, so he disassembled the compressed gas cylinder and high-pressure pump for research.

So Bailixiu naturally knows the structure of high-pressure gas cylinders well, so even Bailixiu can still make it.

In addition to high-pressure gas cylinders, there are also swimming equipment such as flippers, and Bailixiu will also make them together.

Afterwards, the second piece of frogman equipment was naturally a time bomb used to blow up battleships.

There is no way, there is no need to set a time limit, is it possible for people to choose to know that they can't escape, but they will still blow up and not give it! .

As for the third piece of equipment of the frogman special forces, it is also very important, and that is the underwater pistol used for the frogman special forces to save their lives underwater.

Since the resistance of water is more than 800 times that of air, it can kill the enemy's rifle at hundreds of meters on land, but it cannot cause damage to the enemy one meter away underwater.

Of course, this phenomenon is actually a kind of protection for the frogman special forces.

Just imagine, even if you are discovered, you don't have to be afraid. You only need to dive to a depth of more than one meter, and you don't have to be afraid of the machine guns on the battleship.

Of course, the hostile soldiers are not fools. When they find that the rifle is useless, they will definitely jump into the water and plan to fight with the members of the frogmen.

No matter how hard the frogman special team trains, they are still human after all, and the only thing they can do when facing three or four enemy interceptions at the same time is to surrender obediently and wait for their fate.

So at this time, an underwater pistol that can be launched underwater is very important. With it, the frogman special forces will naturally not be afraid of underwater encirclement and suppression.

What's more, Bailixiu is still very clear that in this era, pistols that can be fired underwater have not yet been produced!

In this way, the underwater pistol first launched by Bailixiu can give the frogmen special forces an absolute advantage underwater.

The first underwater pistol that appeared was the SPP-1, which was developed by Su in the 60s, and then launched in the 70s as a pistol that can fight underwater.

The SPP-1 is a manually operated four-barreled pistol.The front of the barrel assembly is hinged to the frame by a pin, and the rear is held in the firing position by a catch.When loading, the barrel is opened like a civilian single-barreled or double-barreled shotgun, and the barrel is loaded from the rear of the barrel.There are no rifling inside the barrel. The SPP-1's double-action firing mechanism uses a rotating firing pin that moves rearward into the cocked position each time the trigger is pulled, while the firing pin seat rotates 1 degrees to align with the next unfired barrel position.

Underwater attack by combat frogmen is a concealed and effective special operations method. In order to deal with combat frogmen, the usual practice is to train special anti-frogman dolphins or use frogmen to carry out anti-frogman operations, whether as Attacking or defending frogmen, their traditional self-defense weapons are diving knives and spear guns.The spear gun is a device that shoots spears with canned compressed air. The underwater shooting range depends on its depth. It is about 15 meters at a water depth of five meters, and only about five meters at a water depth of 40 meters.The disadvantage of the spear gun is that it is bulky, inconvenient to carry, and can only fire one round at a time, and the loading speed is slow.But traditional bullets have extremely short ranges and unstable ballistics when fired underwater because water is more than 800 times denser than air.

所以大名鼎鼎的AK-74在水下发射时有效射程不超过一米，M1911在水下发射时在0.9m处只能在木板上撞出凹痕，在0.6m处只能穿透3mm厚的木板。

Of course, this kind of pistol is not the only firearm for underwater shooting, but the reason why Bailixiu chose this pistol is that the structure of this pistol is similar to that of a revolver, so there is no need to worry about the occasional misfire, after all, it is underwater Fighting is very famous.

In addition to this, there is another point that is more important, that is, the structure of this underwater pistol is simple, which is very convenient for production. After all, Bailixiu doesn't have much time.
