Aerospace and defense systems integrators continue to push for reductions in size, weight, power, and cost (SWaP-C) to support advanced sensor/vetronics payloads onboard unmanned reusable and attritable platforms. Fortunately, advances in the miniaturization of mission-processor and network-switch subsystems are enabling designers of UAS (unmanned aerial system), UGV (unmanned ground vehicle), UUV (unmanned undersea vehicle), and USV (unmanned surface vehicle) platforms to expand their mission capabilities.
