ABSTRACT:
A fuze device for use with a detonator on munitions. A cup and ogive assembly includes an ogive post for aft axial movement upon impact of the device and activation of a spitback lead on the cup. An ogive post activates a first firing pin when the ogive is crushed. A first safe and arm (S&A) device is aligned with the centerplate assembly to provide a first detonator in both the safe and the armed condition by movement of a rotor. A second firing pin is positioned below the first S&A device. It has a blowthrough hole for alignment of the first detonator with the spitback lead. A second S&A device is below the first S&A device, and has a second detonator and rotor that rotates during spin to an armed position to expose the second detonator to the second firing pin. The second rotor is sized and shaped to always permit alignment of the first detonator with the spitback lead. Upon impact on the ogive after launch, the ogive post initiates the first firing pin to detonate the first detonator and the rotor in the second safe and arm device impacts on the second firing pin to detonate the second detonator, such that detonation of either detonators causes the spitback lead to initiate.
