Mission

MDM-1 mod.1 and MDM-2 mod.1 sea bottom mines are intended for employment in minefields to endanger and destroy ships and surfaced or submerged submar¬ines. MDM-3-mod.1 sea bottom mine is used in defensive minefields to destroy small-displacement ships and amphibious assault craft.

Features

The mines are fitted with local three-channel influence exploders activated by target’s acoustic, electromagnetic and hydrodynamic fields sensed in a hemispherical danger zone. The exploders allow the mines to be deployed in both three- and two-channel configurations, with any combination of the channels possible. The mines possess effective anti-sweeping protection from modern influence sweepers and resistance to natural clutter owing to advanced exploder operating principle and anti-sweep device logic, as well as mine timing and ship counting devices employed. Intricate planting patterns and camouflage painting of the mines hinder their detection by sonars of surface ships and submarines, or by mine-hunting devices of remotely operated underwater vehicles.

MDM-1 Mod. 1 sea bottom mine

The mine can be laid by submarines equipped with 534mm torpedo tubes and ships fitted with mine-laying rails/ramps or mine-scattering systems. Surface ships can lay the mines at speeds of up to 15 knots, and submarines – at speeds of up to 8 knots.

When the assigned service life of the mine expires, it is self-destroyed.
