A cylindrical housing for a shock-augmenting charge is provided with axially extending grooves in its outer wall to enhance its radial detonation capability. When used in a cylindrical warhead for augmenting detonation of a main charge of insensitive high explosive, full detonative output is enabled and in addition, a flatter detonation wavefront is generated within the main charge, thereby reducing the need for supplementary waveform shapers.

A shock-augmenting charge for use in initiating detonation of a cylindrical charge of a first explosive material having one end provided with a coaxial cylindrical recess; said charge comprising a cylindrical booster housing coaxially locatable in said recess in spaced relationship from said charge,

A shock-augmenting charge for use in initiating detonation of a cylindrical charge of a first explosive material having one end provided with a coaxial cylindrical recess; said charge comprising a cylindrical booster housing coaxially locatable in said recess in spaced relationship from said charge, have a closed first end and an open second end respectively locatable so as to face inwardly and outwardly of said recess, and containing a cylindrical booster charge of a second explosive material having a higher shock-sensitivity than said first explosive material, exposable in use to a detonation means via the second end of the housing; wherein said booster housing has a cylindrical outer surface provided with a multiplicity of axially extending grooves disposed around its circumference so as to define a multiplicity of radially projecting impact ridges; thereby to enhance radial shock stimulation of the first explosive material circumjacent the booster housing.
