A projectile circuitry assembly for use in projectiles comprising a chassis defining a generally cylindrical a main body portion and further defining an interior cavity for containing one or more projectile components and further defining an antenna aperture through the body portion to expose the interior cavity. In various embodiments the projectile circuitry assembly comprises a plurality of circuit boards and a wrap antenna, the plurality of circuit boards and wrap antenna interconnected via an integrated flex-line to define a single unitary device without the use of a connector, the wrap antenna comprising one or more antenna elements defined on a flexible antenna substrate layer, wherein the plurality of circuit boards are positioned in the interior cavity and the wrap antenna is threaded through the antenna aperture and wrapped circumferentially about an exterior of the cylindrical wall of the body portion.

An electronics package comprising a plurality of mutually parallel, vertically spaced circuit boards of generally circular configuration and electrically connected by a flex circuit comprising a trunk extending circumferentially around the circuit boards and having a branch extending to each circuit board. An electronics package precursor structure and a method of configuring the electronics package from the precursor structure is also disclosed.

Self-locating electronics package precursor structure, method for configuring an electronics package, and electronics package

An energetic material initiation device having a receiver assembly and an initiator assembly that includes an electronic initiator and a pellet assembly with an energetic material. The receiver assembly is configured to be coupled to a firing circuit. When the firing circuit is to be armed, the initiator assembly can be pressed into a socket in the receiver assembly to electrically couple the receiver assembly and the initiator assembly. A method for mounting an energetic material initiation device to a firing circuit is also provided.
