On the other hand, when the mooring line is cut by the mooring type underwater sensor elimination device or the like, the air in the air chamber is released into the sea by the opening means, and at the same time, the seawater flows into the air chamber. As a result, the container does not rise to the surface of the sea, but sinks toward the seabed by its own weight, and reaches the seabed. When the mooring line is cut, the target detecting means is detecting another target, so that the main container starts to function as a seafloor sensor.
