I found on Arma 3 Field Manual - Explosives Info this:

Quote
Naval Mine (Moored)
Moored naval mine is the most used naval mine. Deployed by ships and airplanes, it carries a large load of explosives and a variety of sensors to punish every ship or submarine that sails too close.


Naval Mine (Bottom)
Naval mines sitting on the bottom of the sea are used at depths of up to 200 meters. Deployed by ships and airplanes, a single mine carries a large load of explosives and a variety of sensors to punish every ship that sails too close.


PDM-7
The PDM-7 is an amphibious mine used in shallow waters against light assault boats and amphibious vehicles. A fuse placed on the base serves to discourage handling of the armed mine.

Do these mines exist or not? I searched nearly 0.001‰ of www, but could not find any classnames.
