Is there a mystery submarine in the sea?
There have been instances in the past where mysterious submarines have been discovered on the ocean floor.
I have created an imaginary image based on the phrase “Mysterious Submarine found at the bottom of the Sea”.
海底で発見された謎の潜水艦
These submarines had unknown owners and purposes, and raised many questions.
However, there is no conclusive evidence to determine which organization or country operated these submarines, and so it remains a matter of speculation.
Given that there are still many unexplored areas of the sea floor, it is possible that more mystery submarines may be discovered in the future.
