Submarine Batteries

The Submarine Batteries program within the Navy focuses on procuring replacement Valve Regulated Lead Acid (VRLA) batteries for various classes of submarines, including LOS ANGELES, SEAWOLF, OHIO SSBN/SSGNs, and VIRGINIA. The primary objective is to ensure these submarines have a reliable backup power source crucial for maintaining ship and reactor plant safety. The program also includes production engineering efforts managed by the In-Service Engineering Agent (ISEA) at NSWC Crane, which addresses battery performance issues and conducts qualification testing.

A significant goal of the Submarine Batteries program is to maintain operational readiness and strategic deterrence capabilities of the submarine fleet. This involves meeting the high demands placed by Combatant Commanders for strategic deterrence, force protection, and sensitive Intelligence, Surveillance, and Reconnaissance (ISR) missions. The procurement strategy is based on a multi-year Firm Fixed Price contract that defines fixed per-cell costs over several fiscal years, with yearly procurement quantities adjusted according to fleet requirements.

The program emphasizes improving logistics and flexibility in battery replacement schedules by procuring additional shipsets and installation tray sets. These components are essential during battery replacements to minimize operational disruptions. Furthermore, NSWC Crane leads efforts in root cause analysis and corrective actions to enhance battery life and reliability. Resources are allocated to Puget Sound and Portsmouth Naval Shipyards for VRLA battery inventory management, maintenance, and storage.

The Submarine Batteries program aims to support the average replacement requirement of 18 battery ship sets annually while adapting to varying fleet operational needs. By ensuring timely procurement and installation of submarine batteries, the program plays a critical role in sustaining the Navy's underwater capabilities and readiness for future missions.
