Abwehrflammenwerfer 42

These were usually buried at intervals of 11 to 27 metres (12 to 30 yd) covering road blocks, landing beaches, harbour walls and other obstacles.

They were normally mixed in with other mines or emplaced behind barbed wire and could be command detonated or triggered by tripwires or other devices.

The mine consisted of a large fuel cylinder 53 centimetres (21 in) high and 30 centimetres (12 in) with a capacity of 29.5 litres (6.5 imp gal; 7.8 US gal) containing a black viscid liquid; a mix of light, medium, and heavy oils.

A second, smaller cylinder, 67 millimetres (2.6 in) in diameter and 25 centimetres (9.8 in) high, was mounted on top of the fuel cylinder; it contained the propellant powder, which was normally either black powder or a mixture of nitrocellulose and diethylene glycol dinitrate.

When the mine was triggered, a squib charge ignited the propellant, creating a burst of hot gas which forced the fuel from the main cylinder and out of the flame tube.
