The smallest submarine in the world

Since World War II, submarines have played an important role in naval battles. Germany used submarines to break up the warships and merchant ships of the British Empire, and its submarines were able to launch a very unexpected strike effect to a certain extent.

Among the naval weapons in the world, submarines and aircraft carriers are extremely important weapons and equipment, which have become the key development targets of navies in various countries. Aircraft carriers deter other countries in the light, while submarines give more terrible naval combat power in the dark.

Submarines are most famous for their concealment. Because it is difficult to detect, once the submarine approaches the warship at a certain distance, it can give a heavy blow.

After the conventional submarine has been in active service for a period of time, the nuclear-powered submarine has followed closely and become the high-power submarine that all countries dream of.

In addition, more and more countries are studying submarines with larger displacement. These submarines have a very large tonnage, with the largest tonnage in the United States and Russia. However, everyone's understanding of submarines is not that the bigger the better, because submarines are too big to expose their targets.

Therefore, small submarines seem to be easily overlooked. It is almost invisible. Under the cover of seawater, this humble "little guy" is the most dangerous existence.

The website of Forbes magazine published a submarine photo, which was taken by a foreign tourist in Havana Port, Cuba. It's a picture of the water surface and steps. The protagonist in the center of this picture is a submarine that looks very small to the naked eye.

After seeing this submarine, everyone talked a lot, but everyone agreed that this submarine was a service submarine of Cuba. At the same time, it is also the smallest submarine in the world. After being exposed by this photo, this miniature submarine attracted people's attention here.

According to Forbes.com, this submarine is the only one in Cuba. In fact, during the Cold War, Cuba, as a strategic location, naturally had many submarines. Cuba acquired a large number of conventional submarines from the Soviet Union. By 2020, these submarines have fallen into disrepair and have to be retired. So this seemingly small submarine undertook the underwater mission of Cuba.

This submarine is called "Delfim" class submarine, with a displacement of about100t and a total length of only 2 1 m.. Such a small size is really rare. The American "NR-65,438+0" 400-ton submarine, once known as the smallest submarine, is simply a monster in front of Delfim.

The visual effect of this miniature submarine really has a different kind of intimacy, because it is small and looks a little cute, but the submarine is a submarine after all, and as a killing weapon on the seabed, its deterrent ability is still great.

The Cuban military is very strict about the secrecy of the Delfim class submarine, and it is not entirely sure whether it can carry a large number of torpedoes. To be sure, it can carry a torpedo launcher of about 500 mm.

The biggest function of "Delfim" is not to fight, but to carry out various secret investigation tasks. It is very difficult to find a small body in seawater, and it is a bit unreasonable not to use it for secret missions.
