TM-46 (TM 46)

TM-46 is a Soviet pressure-action anti-tank mine, adopted for service in 1946. Replaced all previous Soviet models of metal anti-tank mines: TM-35, TM-39, TM-41, TM-43, TM-44.

The modification under the designation TMN-46 is distinguished by the presence at the bottom of the mine of a special socket for installing a non-removable fuse.

The TM-46 can be installed: on the ground, in the ground, in the snow, and underwater, both manually and with the help of mine spreaders (PMR-1, PMR-2), minelayers (GMZ, PMZ-3, PMZ-4 ), as well as as a helicopter mining system (VMR-2).

An explosion occurs when a tank track or car wheel hits the top cover of a mine with an MVM pressure-action fuse installed and cocked into the firing position. In this case, the cover, under the tank's weight, settles together with the fuse into the intermediate detonator block. If the force acting vertically exceeds 140 kg, the bushing head breaks through the diaphragm. It releases the firing pin, which, under the action of a compressed mainspring, pierces the MD-6 fuse, initiating an additional detonator (a tetryl block weighing 40 g). The explosion of the tetryl initiates the main charge of the mine.

The body of the mine was a flat, round, stamped steel box with a neck for filling explosives when loaded. An explosive charge was placed inside the box, and a fuse was installed.

Production of the TM-46 was discontinued with the adoption of the TM-57 mine (developed in 1956).
