As we all know, the performance of the Italian army during World War II has been ridiculed by the world, and it can be called a pig teammate. So much so that the Germans said of their ally Italy: If Italy were on the side of the Allies, we would only need 6 divisions to defeat them, but if they joined our side, we would need 50 divisions to protect them.
Is the performance of the Italian army really worthless? The answer is definitely no, and they also have a highlight moment: 6 frogmen control torpedoes to take out 3 large British battleships.
Weren't torpedoes fired from submarines? How is it controlled by people? Listen to me slowly: as early as 1935, two Italian engineers began the development of manned torpedoes, and by early 1940, manned torpedoes were finally successfully tested. The torpedo is 7.3 meters long, mounted with a 1.1 hp electric motor, powered by 30 60-volt batteries, and carries two explosive devices in the front of the torpedo on which two frogmen in wetsuits can ride. During the mission, the front frogman is responsible for controlling the torpedo, and the frogman behind is responsible for installing the explosive device, because this torpedo resembles a swimming pig in the water, so it is also called "pig cunning".
Although the name is not domineering, but the appearance of "Pig" can be described as amazing, why say so, look at its target Alexandria Alert You know.
The entrance to Alexandria is covered with countless mines 5 kilometers away, and the front of the entrance is chaotically intertwined with many cables of automatic alarm systems. And there was only one narrow channel for warships to enter and exit, and in order to prevent the enemy from sneaking in secretly at night, three huge and solid anti-submarine nets closed the entrance tightly. At night, countless searchlights change angles, illuminating miles of water with shining pillars of light.
On December 18, 1941, the Italian submarine "Skye" released three "pig" torpedoes carried outside Alexandria, Egypt, at midnight, three torpedoes broke through the anti-submarine net, successfully installed explosive devices at the bottom of three British warships, just after 6 o'clock in the morning, the explosive device detonated on time, the British "Brave" and "Queen Elizabeth" two warships and "Saguna" oil tanker were all blown up and sunk in Alexandria. The explosion also affected nearby warships and installations, and the attack on the Mediterranean Fleet suffered heavy losses. But the 6 Italian frogmen who participated in the operation were all captured by the British army, and the British Admiral Cunningham suddenly realized that it turned out to be a "good thing" done by the damned submarine
At that time, Japan received this news and received a treasure, and according to this idea, it made a torpedo to return to the sky. The difference between the two is: the Italian "pig" is a convertible; And the Huitian torpedo is an airtight car, which is locked from the outside when it starts, and the operator is left to wait for death.
