Life cycle cost containment of the Strategic Weapons System (SWS), without loss of ultra high performance, is a very important goal of the entire Navy Strategic Systems Program community. Boeing is responding by guiding large advances in the state-of-the-art of fiber optic gyro technology and developing a new associated navigation system. All of the very stringent Strategic Weapons System (SWS) performance, reliability, and maintainability requirements continue to be exceeded by the Electrostatically Supported Gyro Navigator (ESGN). The Electrostatically Supported Gyro (ESG), in production for over 25 years, is the most critical and costly component of the current inertial navigation system. ESGs, however, are extremely expensive to manufacture and repair. Furthermore, the system-level electronic components are difficult to replace because they are rapidly becoming obsolete. The current initiative is focused on containing total ownership costs, especially maintenance costs, without any relaxation of performance, reliability, or maintainability requirements. The key element of this initiative is new gyro technology based on rapidly improving precision Interferometric Fiber Optic Gyro IFOG performance, along with cost reduction of fiber and manufacturing processes. This paper discusses the challenges and the approach currently being taken to further the development of high precision IFOG technology and its associated inertial navigation system for application to the SSBN.
