APM series directional fragmentation mines

The APM-1, APM-2, APM-3, APM 19, and APM 29 are Austrian directional fragmentation mines similar to the United States Claymore mine. The mine's cases are made from moulded plastic have convex faces. They contain a matrix of 5 millimeter diameter steel balls weighing 0.5 grams laid over a Composition B charge. When triggered the mines project the fragments in a horizontal arc of approximately 60 degrees.

The mines were not produced in numerical order, the APM-3 was superseded by the APM-2. The APM-1 is the smallest of the mines, it uses a tripod mounting with a pan and tilt head. The APM-2 uses two scissor type legs to position.

The mines can be command or tripwire activated, and can be fitted with a time delay fuze ranging from one minute to twenty four hours.

Production of APM-1 and APM-2 ceased in 1980s, though both have been reported as used in Angola.

  1. The main charge is believed to be Composition B.
  2. The APM 29 uses larger 5.6 mm diameter fragments, giving it a greater effective range.
  3. The mines are considered effective when the fragments at the range are capable of penetrating 20 mm of Pine or 4 mm of Aluminium.
