Interesting Holidays:
One of the most common misconceptions regarding submarines relates to their maximum depth of immersion. It is believed that they can swim at very great depths, reaching many kilometers. But in reality this is not at all the case.
Of course, over time the submarines sank deeper, increasing the cruising range and payload. But by the beginning of the First World War, the submarines sank only to a depth of ten meters, and this was quite enough to secretly move in the water column.
Modern submarines are far from their predecessors. But the majority of small and medium submarines cannot dive more than a few tens of meters. And only nuclear submarines – these giants, capable of being under water for many months – sink to depths of several hundred meters. The greatest depth for nuclear submarines barely exceeds 600 meters, and it is reached literally at the limit of possibilities.

Investigating the question “When is International Submarine Day 2020?” we found this matter so important that it is impossible to deal without any additional clarifications and explanations. In general, modern submarines are considered to be the most invulnerable and destructive naval weapons in the entire history of the sea. Underwater vessels can secretly act in the thickness of the sea or oceans for months. In addition, we can’t but mention that their weapons are able to inflict insane damage.
The desire to create a submarine was so great that by 1727 several different inventors had patented at least 14 projects. And this is only in England.
For the first time this kind of vessels was used as a kind of military weapons. It happened during the American Revolution. Later, that object was nicknamed “Turtle”. It was invented on definite purpose. And it received this name due to its ultra-small dimensions and was able to involve only one person. It made an attempt to sink a British military ship in New York, attaching a powder charge to its bottom. But this attempt failed unfortunately, as the charge did not work. The captain didn’t want to risk being blown up, so the ship hurried to go to the open sea.
However, contemporary combat submarines do not need to reach great depths, as the water hides the presence of any objects very well, and their search turns into a rather difficult task. So all submarines move relatively shallowly, and only small-sized research vehicles of special designs fall to a great depth.
