Abstract: An electronic fuze package and method includes a left casing comprising a substantially flat left surface having left casing recesses and a right casing comprising a substantially flat right surface having right casing recesses. The combination of the left casing and the right casing defines a fuze casing for the mounting of fuze components. The fuze package also includes plated-on electrical tracks on the left casing, including component connections immediately adjacent to the casing recesses for electrically coupling the fuze components in a fuze circuit. The fuze package can be made of thermoplastic left and right casings which can be epoxy-glued together. Copper can be used for the plated-on electrical tracks.

Abstract: In a weapon subject to linear acceleration and spin, including a detonator and an explosive charge, the safing and arming device comprising a housing, a setback spring configuration restraining a ribbon spiral unwinder, and a detonator-enabling circuit which provides a fail safe for the omission of the safing and arming device from the fuze assembly.
