Abstract: A controlled fragmentation explosive device is disclosed. Fragmentation crol is achieved by providing both the inner and outer surfaces of a cylindrical case with intersecting longitudinal and circumferential "v" grooves having specific depth relationships. The inner and outer grooves are aligned with each other. The outer grooves are filled with a material for improving the acoustic impedence mismatch between the case and the volume within the "v" groove.
