SPM Object Mine

The SPM medium adhesive mine belongs to the class of object time-delay mines and is designed to damage or destroy mobile and stationary targets with metal components. The target is defeated by the blast force of a 1 kg MS explosive charge.

The mine is intended for use in sabotage operations to destroy fuel tanks, damage railway structures and rolling stock, aircraft, helicopters, boats, and other targets.

The mine is primarily used against unarmored or lightly armored targets (tanks, pipelines, electrical fittings, hydraulic fittings, shut-off devices, armored personnel carriers, aircraft, helicopters, power transmission supports).

The mine can also be used underwater to demolish underwater targets and disable small-displacement vessels.

The SPM mine is primarily used by Navy combat swimmer units and marine infantry units.

The mine is attached to the target by means of two arc-shaped magnets fixed to the flat lower surface of the mine. The mine detonates after expiration of the delay period of a VZD-1M or VZD-20M time-delay detonator.

The detonator for the SPM mine is equipped with six replaceable metal elements (No. 1, 3, 5, 6, 7, 8). The number of the metal element determines the delay time. By selecting the required metal element, the detonator actuation time can be changed.

It has no target sensors. It has no anti-removal or self-destruct elements.
