SBSD Advanced Submarine System Development
Abstract
SBSD Concept and System Definition Prototyping, and Technology Development Efforts. The SBSD program supports design, systems engineering, prototyping, and vendor qualification activities needed to develop CMC design, the OHIO Replacement whole ship design, and component development. OHIO Replacement design efforts support decisions on missile tube hull insert manufacturing in FY 2010 and missile compartment construction strategy down-select in FY 2011. The SBSD design timelines are based on the approach proven on VIRGINIA Class Program, adjusted for the additional complexity of a missile compartment and Strategic Weapons Systems (SWS). Planned technical studies and prototyping are necessary to reduce risks associated with updating SSBN system designs for current technical standards and demonstrating design feasibility of technical options to inform the establishment of detailed requirements. The Navy is investing $150M ($50M/year in FY 2012-2014) in Design for Affordability (DFA) initiatives similar to those employed successfully for VIRGINIA Class, but will be further tailored to the uniqueness of OHIO Replacement to drive down overall program costs. Efforts will focus on reducing ship construction costs through implementing more effective design features to produce a more affordable/producible class. As part of this effort, alternative contracting strategies will be examined. Activities planned for FY 2010, FY 2011 and FY 2012 include the design of a common missile compartment to satisfy the requirements of both the US and the UK, to mature required technologies, and to re-host the TRIDENT II D5 Strategic Weapon System (Launcher, Fire Control and Navigation) while ensuring no degradation to D5 security, safety, and performance. In addition, whole ship design efforts are focused on technologies requiring significant development times and those technologies with early design impacts. These include propulsor development, ship control (e.g., control surfaces), and ship signatures. These technologies are critical to understand stealth capabilities for a ship class that will be in service until the 2080s. Ship concept design efforts include important pre-construction activities such as trade studies of ship requirements, risk characterization of technology options, improvement and validation of performance prediction tools, and improvement of design tools. Technology development will address maturation of technologies that must be mature to support ship design and construction schedules such as the propulsor, maneuvering/ship control, and signatures.
