Abstract
A fuze for a submunition is miniaturized in size by forming the fuze of a micro-electromechanical systems (“MEMS”) velocity sensor (38, 32, 34 and 36), a MEMs shock detector (31), a DC power supply (30) and one of the MEMs arm-fire device (2, FIG. 1) or MEMs safe and arm device (2, FIG. 5). Multiple fuzes may be incorporated in a fuze to ensure detonation of the explosive charge, should one fuze fail. A millimeter-microwave (“MMW”) receiver-decoder may be included to permit remote detonation on command from a remote transmitter (52) and/or a microprocessor (54) may be included to time the detonation to the physical characteristics of the target.
