Paper Abstract

This paper describes the payload delivery system developed and proven to deploy an electronic warfare device to specific, predetermined locations on the battlefield. Initially called the Artillery Delivered Expendable Jammer (AD/EXJAM), it is now designated the Air Delivered-Ground (Deployed) Expendable Jammer (AD-G/EXJAM). The initial units were demonstrated from 155 MM artillery; the later units, from UAV's, helicopters and slow moving, fixed wing aircraft. While these two delivery systems were originally designed specifically for the EXJAM system, the concept is directly applicable to unattended ground sensors that require unmanned remote emplacement. Keys to the success of the jammer included design, development and field testing of power supplies, antennas, deployment systems and packaging to allow payloads to withstand high-g impact and other severe environments typically encountered. The artillery deployed systems were designed to be `wooden' rounds needing no special handling and storing. These systems treat the payload as independent elements which are self-ejected from a fired M483A1 or M864 round and are completely automatic upon hitting the ground. The more recent payloads can be delivered from UAV's and include remote control capabilities, increased operating life and increased power output. The present payload is packaged into a cylindrical shape, approximately six inches in diameter and 6.5 inches long and are contained within a carrier, attached to an Unmanned Air Vehicle (UAV) or any other air vehicle. Upon reaching the dispensing point, the release command can be issue by either the UAV or a separate ground control unit in RF contact with the carrier. The carrier then begins a timed dispensing sequence that has been selected for optimum payload emplacement in the target area. New developments include a design and subsystem demonstration of a tactical munitions dispenser variant of the deployment system. Operational characteristics of any specific sensors or payloads will not be addressed.
