Description

Submarine drone system {SUBMARINE DRONE SYSTEM}

The present invention relates to a drone system of a submarine, and more particularly, to a drone system of a submarine that can use a drone in a submarine to enable attack, surveillance, and reconnaissance from a distance in order to lower the probability of detection.

As is well known, a submarine is a weapon system that performs covert reconnaissance and surveillance missions underwater.

In modern warfare, due to the stealth of submarines, the demand is increasing day by day, and it is usually used mainly for war suppression and surveillance/reconnaissance.

In order to block such submarine activities, the other country (that is, the enemy country) installs acoustic sensors capable of detecting submarines on the sea floor, or uses anti-submarine helicopters and reconnaissance ships.

For this reason, if a submarine approaches an enemy enemy, it is highly likely to be detected, and there is a high possibility of friction between countries.

In addition, there is a problem in that it is difficult to avoid dangerous areas at high speed underwater during detection.
