Future Surface Combatant (FSC) Analysis of Alternatives (AoA) is expected to initiate in early to mid FY18 and include requirements for advanced high energy weapons and sensors. The nature of the new combat systems places new requirements and unprecedented challenges on power systems based on current design rules, standards, and interfaces. These new systems require higher, cleaner, and more stable power in comparison to the systems they are replacing; the integration and management of stored energy; and the ability to utilize stored energy virtually on demand. This requires a higher degree of integration of combat and mission systems with hull, mechanical, and electrical (HME) systems as the power system becomes a critical link in the kill chain. It is imperative that design and assessment tools are cohesively integrated and able to rapidly analyze various system configurations, assess their reliability and survivability, and conduct configuration trade studies.
The FSC program has developed a draft Initial Capabilities Document (ICD), which captures very high level fleet architecture Critical Requirements (CRs). The plan for the AoA is to use a set based design approach to decompose the ICD requirements for the total ship platform and ship system alternatives. Design methodologies must provide for system configuration characteristics and requirements to be traceable to the CRs.
The current NSWCPD and NAVSEA power and energy system design tools and methods should be assessed in reference to these needs. This activity will provide the Navy with an opportunity to establish a framework for best achieving such a set-based design AoA using existing resources, identify essential elements and existing gaps for digital system model lifecycle starting with the AoA, and suggests a baseline roadmap for incremental progress toward this vision. This activity will extend lessons learned to other ship systems as appropriate.
