ABSTRACT:
A fuse apparatus for a depth charge or the like has a primary fuse that operates at a relatively shallow depth to position a detonator in line with a firing pin, and a secondary fuse that operates to release the firing pin to explose the detonator. A safety mechanism normally prevents operation of the primary fuse, but can be canceled to allow such operation. The secondary fuse cannot itself operate until the primary fuse has operated, so that the two fuses must operate successively to set off the detonator. In addition the two fuses operate along mutually perpendicular axes, so accidental jarring of the device cannot set it off. Finally the arrangement is constructed to leak slightly so that in the event it fails to go off it will rapidly become inoperative.
