Abstract
The Modular Payload standard, often referred to as “Mod Payload,” was originally developed to promote modularity in the DoD arsenal of Group 2 Unmanned Aerial Systems (UAS). It has since been expanded to support Groups 1 and 3 UAS as well as USVs and dismounts. The Modular Payload Expanded Capability (MPx), developed under the Joint Threat Warning System (JTWS) program, further expanded the Mod Payload standard defining a larger class of payload to support both manned aircraft and maritime platforms. The Modular Payload Micro (MPu) expanded the Mod Payload standard once again defining a smaller class of payloads better suited to support even smaller UAS and dismounts. The Mod Payload standard aims to define the common interfaces and attributes for both EW / SIGINT / communications payloads and also the platforms into which such payloads will be integrated.
