A warhead configuration for forming a hole through a wall of a target, the warhead configuration comprising a charge of explosive material and a liner. The charge has an axis and a front surface. The front surface includes two annular front surface portions, an inner and an outer annular portion, circumscribing the axis. Each of the annular front surface portions is configured so as to exhibit a concave profile as viewed in a cross-section through the charge parallel to the axis. The liner includes a first liner disposed adjacent to the inner annular portion and a second liner disposed adjacent to the outer annular portion such that, when the charge is detonated, material from the first liner is formed into a first expanding explosively formed ring and material from the second liner is formed into a second explosively formed ring.

Double explosively-formed ring (DEFR) warhead

A warhead configuration for forming a large-diameter hole through a wall of a target includes a shaped charge of explosive material presenting an annular front surface portion circumscribing an axis of the charge. The annular front surface portion exhibits a concave profile as viewed in cross-section through the axis, at least part of the concave profile being configured such that a vector projecting outward from the part normal to the annular front surface portion diverges from the axis. A liner is provided adjacent to at least part of the annular front surface portion.
