Abstract: A double-ended, high-explosive, anti-tank mine, adapted to be carried into he air, in a projectile, for example, ejected, deployed and come to rest on either end, comprises a housing having a short cylindrical side wall and two end walls removably attached to the side wall, an annular main charge of high explosive material having concave end surfaces lined with hardened metal missile plates, a clearing charge of propellant located between the main charge and each end wall, a tubular booster charge mounted within the annular main charge, and a fuze mounted in the housing and comprising a conventional proximity fuze for sensing the presence of a tank and producing a firing signal, a firing circuit including a gravity-controlled liquid mercury switch having at least three electrodes, and a battery connected to the two clearing charges in such manner that the upper clearing charge is initiated in response to the firing signal, prior to initiation of the main charge.
