The Underwater Bottom Mine PDM-250 is designed to be effective against marine surface vessels of any class.
It is a new generation mine completely made of non-magnetic materials according to up-to-date technologies.
The shape of the mine, as well as its completely non-magnetic structure and special anti-sonar camouflage coating, ensure that it merges with the environment.
The mine is transitioned into armed state at expiration of the safety time counted by a microprocessor timer.
The mine is manufactured in two modifications, with or without anti-sonar coating.
