Technical Applications Programs
Abstract
The Multi Star Enhanced Prelaunch (MEP) project leverages the capability of the D5 Life Extension Guidance (Mk6 Mod1) to sight two stars vice one combined with the interface updates to the Fire Control and Navigation subsystem, allowing for in-flight correction, the potential to operate in environments where Global Positioning System (GPS) is denied, and potential future relief to the strict tolerance requirements of the strategic navigator on the current OHIO class submarines and the COLUMBIA Class program. The Systems Engineering Modeling and Simulation capability will consist of three elements: Model Based Design, Strategic Weapon System (SWS) Integrated Modeling and Simulation/Common Architecture & Framework, and SWS Enhancement Ground Test. This effort will provide the capability to comprehensively evaluate and test the integrated SWS within representative operational environments, providing unprecedented visibility across the SWS and system performance characterization equivalent to flight testing. This capability will enable trade space analysis to identify technical margin, subsystem interactions, and lifecycle affordability opportunities to include other services and be able to identify the benefits and risks of commonality to the individual programs, requirements and CONOPs modifications that could facilitate commonality, potential common acquisition strategies between the services, and total life cycle cost implications. In FY 2020, development for D5 Life Extension 2 (D5LE2) commences. The D5LE2 will include System Level Architecture Trades and Design Processes in which initial planning and system technology trade actives are necessary to begin preparing for D5LE2 SRR currently scheduled for FY 2025. (Investments are required starting in FY20 to begin trading system architecture concepts and implementing modern model based design and system engineering practices.) D5LE2 Avionics Architecture & Technology Development will include legacy D5 and D5LE electronic technologies now obsolete and manufacturing lines shutdown. Avionics architectures, sensor, bus and component designs are inherently complex with design and manufacturing technologies continuously evolving. Technology advancements and improved system architecture concepts have the potential to improve system capability, modularity, manufacturability, SWS operations and sustainability.
