A plurality of objects is deployed in generally radial directions at low velocities in order to achieve a predetermined pattern of the deployed objects. The device has a metal inner wall member (20, 120) having a plurality of annular cylindrical segments of differing outside diameters, an explosive body (22, 122) of low velocity explosive, and a plurality of arrays (40, 140) positioned coaxially with and exteriorly of the explosive body (22, 122) and spaced along the length of the explosive body (22, 122). Each array (40, 140) comprises a plurality of objects (28). The explosive body (22, 122) can be in the form of a plurality of annular sections which provide the objects (28) in each array with an amount of energy different from that provided to each of the objects in the adjacent array. An annular flange (32) can separate the forward end of the explosive body (22, 122) from a booster ring (66), or the booster ring (166) can be positioned within a central cavity of the inner wall member (120). A plurality of holes (168) in the inner wall member (120) can expose the explosive body (122) to the detonation of the booster ring (166). The holes (168) can be aligned with the objects (28) in the radially adjacent array and/or aligned with points between adjacent objects. Outwardly extending flanges (32, 34 or 132, 134) can serve as reflection surfaces for explosive pressure waves. One or more safe arm fuzes (90, 92, 190) can be encased in foam (94, 194) and positioned within an annular structure (76, 120). An annular explosive section can be in the form of discrete segments spaced apart about the circumference of the explosive body.
