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and lock balls retained by the tubular body in such a position as to interfere with and lock the firing element in a withdrawn position.
