TM-89 Anti-Tank Mine

The TM-89 is an anti-tank underbelly mine. It is designed to disable enemy tracked and wheeled vehicles. An enemy tank is defeated by penetration of the hull bottom by a shaped-charge jet when the mine charge detonates at the moment the tank is positioned over the mine. In this case, the tank is completely disabled, usually with the death of the crew.

If a tank runs over the mine with its track, the explosion assumes a conventional high-explosive effect, severing the tank track, destroying a road wheel, and often damaging the suspension arm as well.

The mine fuze is magnetic and is an integral part of the mine design.

The mine is laid on the ground, in the ground, or in snow manually or by means of mechanized equipment — the GMZ-3 tracked mine-laying vehicle or the VSM-1 helicopter mine-laying system.

For carrying, the mine has a removable handle made of green nylon webbing. The handle is attached to a special bracket on the bottom of the mine. If the mine is laid using mechanized equipment, the handle is removed before the mine is loaded into the carrier.

The mine has very high sensitivity to changes in the magnetic field and may detonate when a person carrying metal objects approaches it (helmet, weapon, footwear with nailed soles, etc.), or even as a result of moving the mine itself across terrain within 200 meters of high-voltage power lines, operating radar stations, and powerful radio stations. Any electromagnetic influence (magnetic field, radio emission from a mine detector) will inevitably cause the fuze to function.

The mine is searched for only by visual observation. Sappers searching for TM-89 mines must not carry any ferromagnetic objects: weapons, shovel, helmet, knife, probe, etc.; footwear must not have steel heel plates or nails.

Externally and in terms of dimensions, the TM-89 mine resembles the TM-62M anti-tank mine; however, the explosive charge in the mine casing is arranged so as to form a shaped-charge cavity.

Coloring

The mine is painted olive green.

Marking

Standard marking, applied in black paint to one of the side walls of the mine and containing:

TM-89 — mine code designation.

B-01-07 — manufacturer plant code — batch number — year of manufacture
