Sustaining Electronic Sub-Systems Evaluation

NCMS Project #: 140933

Problem: Due to obsolescence and the inability to procure the required electronics, the Naval Undersea Warfare Center (NUWC) is looking for a replacement to the Electronics Sub System (ESS) of the Fleet Exercise Section (FES) found in torpedoes. Obsolescence issues exist in the electronics section of the FES, causing significant impact in maintenance and sustainment, supportability, and the time to identify and isolate failures. Complicating this issue is the lack of adequate card-level test set capabilities to assist with fault isolation, troubleshooting, and repair efforts. The lack of existing requirements and design documentation results in a situation where the program is unable to identify and assess potential program risks associated with the FES.

Benefit: By completing the suggested refurbishment operation successfully, re-engineering processes, methods, and dataset could be established that would set the stage for future reengineering possibilities, giving a viable, cost effective option to the expenditures associated with developing new. Within the re-engineering process, technologies may be created that can be utilized in other programs, thus saving research and development funds that could be redistributed to lowering the costs of goods and services.

Solution/Approach: To further sustain the ESS, the efforts of this project will evaluate the current FES electronics, and document the system functional requirements and interfaces. Additionally, capabilities to improve maintenance and sustainment of this system will be evaluated and assessed and added as appropriate to align future requirements and ensure all requirements are thoroughly captured and the system will remain compatible with modern standards and interfaces. Phases of the effort will happen sequentially with outputs of one phase being provided as inputs to the subsequent phase.

Phase 1: System Assessment and Requirements Baseline – This effort will examine existing designs of the ESS components as well as current documentation. Objective of this phase is to develop functional and operational architecture. This phase will conclude with a System Requirements Review (SRR) and CDRL deliveries.
