Abstract : There is provided in the present invention an unlined, Munroe Effect device for breaching structures in urban terrain during combat or emergency operations. The device is constructed as an unlined, linear, shaped explosive charge which upon detonation directs an explosive jet into the wall or other structure. The shaped charge is formed with a honeycombed substrate of metal in which the interstices of the substrate are filled with and the substrate is covered by the explosive material such that the honeycombed substrate is embedded in the explosive material. The honeycombed substrate can be aluminum while the explosive material can be any suitable explosive material such as plastic bonded, castable, or curable explosive having urethane-like characteristics. The explosive material and substrate, prior to curing of the explosive material, are formed into a semi-cylindrical or equivalent shape so as to create a cavity which directs an explosive jet into the wall or other structure. The unlined, linear, shaped explosive charge can be initiated by a booster charge detonated by explosive cord.
