The similar magnet- and horn sea mines are still using, what was used in the First World War, but the advantages in materials like using composites in the cores of mines make those weapons more dangerous because composite core would not be detected by using magnets. Also, computers are allowed to make so-called smart mines, what detonates only near enemy major surface combatants or submarines. Some of those mines have the nuclear detonator, what makes them capable to destroy the entire battle group. In those cases, the mines can use voice compilation and SONARS, what detects the form of the target, and then those weapons would be detonated. They can be delivered from aircraft, surface ships, and submarines. Some of them are actually very advanced torpedos, what uses RTG or some other long-term propulsion. Those torpedos can deliver to the sea eve
