Abstract
A marine mine 10 (FIG. 4) is arranged to have a buoyancy state in which the force of gravity and/or buoyancy act on the mine in a vertical direction to move the mine through the water and includes control means operable to control guidance surfaces 16, 17, 18 projecting from the mine to impart a lateral gliding movement to the mine to steer it to intercept a target. The buoyancy state is determined by a buoyancy compartment forming part of the mine body which may be flooded to lay the mine at a submerged station. Sonar sensing means detecting a target causes air from a cartridge to displace water from the buoyancy compartment to provide an upward buoyancy force which is used to give lateral movement to the mine which is steered on a trajectory intercepting the target.
