      SFSS is a universal, small, and low cost, functionally redundant flight termination system (FTS) that incorporates encoding, processing and TSPI capabilities, provides critical health/safety/welfare monitoring and allows for highly efficient telemetering of weapon application and FTS data. The SFSS is intended as a solution to provide weapon system developers, test agencies, and range safety officers the ability to track, monitor, and if necessary, terminate all types of weapon systems. The SFSS components are intended to significantly reduce the recurring costs and improve the quality of test support by minimizing physical intrusion into weapon systems, and potentially eliminating the need for warhead removal. In addition, a common hardware suite assists in reducing the overall system cost of acquisition, a key element in today's world of stressed budgets. The SFSS is designed to interface with newly developed weapon systems, while providing the capability to be integrated into existing weapon systems with nominal modifications to the platform. The SFSS development is a multi-disciplinary effort, whose participating organizations include industry suppliers, range and system safety representatives, and technical offices from all branches of the armed services, as well as the weapons vendors to ensure that applicable technical and regulatory requirements are met. The original requirements for the project were defined within the SFSS System Performance Specification (SPS), which has undergone a number of updates as the design effort has progressed from concept to assembly and debug of the prototype components. This paper will provide an overview of the overall program status, key features of the SFSS including features added during development, critical design challenges, and additional activities planned to enhance the functionality of the system.
