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.
