Abstract: A submunition fuse presenting a tubular body; a support housed in sliding manner in the tubular body; a firing element housed in sliding manner in the support; a detonating element mounted facing the firing element in the armed position of the fuse; a strip fitted to the top of the support, projecting from the tubular body, and which, during descent of the fuse, exerts aerodynamic force on the support in a direction away from the detonating element; a first thrust spring acting on the support to generate a first thrust, in the direction of the detonating element, not exceeding the aerodynamic force; a second thrust spring acting on the firing element to generate a second thrust in the direction of the detonating element; and lock balls retained by the tubular body in such a position as to interfere with and lock the firing element in a withdrawn position.

Abstract: The tubular shell comprises: a casing having a fuse-carrying forward portion, a substantially cylindrical intermediate portion formed with an inside undercut delimited by a rear shoulder and a front shoulder, and a tapered rear portion; a base plug received in the rear portion; at least three pre-formed, rigid segments of a cylindrical liner, received in the undercut so that they abut both shoulders, each segment being of a cross-section smaller than the aperture of the casing in its rear portion. The backs of the segments are relieved to provide desired weight and/or other inertial properties. A narrow wedge is used as a final restraining segment.
