A watercraft may have a shaped charge and a gas chamber. The gas chamber may be adjacent to the shaped charge in a direction of action of the shaped charge. The gas chamber can be varied in length in the direction of action of the shaped charge. Further, the shaped charge may be movable parallel to the direction of action of the shaped charge. A threaded rod can be used to move the shaped charge. In some cases a length of the gas chamber is variable between 0.1-times and 10.0 times a diameter of the shaped charge. The watercraft may be configured in some instances as an unmanned underwater vehicle.

A container system for storing and launching mines comprising a container and conveyors. The conveyors are placed inside the container and are oriented such that mines can be stored or transported on the conveyors. At least two of the conveyors being parallel and placed with a vertical height difference in at least two layers such that mines can be stored in multiple layers in the container for optimal use of the storage space in a container thus reducing the space required for mine storage on a ship or increasing the capacity of mines on a ship. Having an elevator container and a launch container in the system ensures that mines from a storage container can be transported to the ramp of the launch container and launched automatically.
