L3Harris Technologies has been awarded a contract by General Dynamics Electric Boat (GDEB) to supply battery monitoring systems for the US Navy’s Virginia– and Columbia-class submarine programmes.
The contracted systems are intended to give submarine crews real-time assessments of battery health, enhancing vessel readiness and operational effectiveness.

While L3Harris has not disclosed specific details about the systems to be supplied, its portfolio includes Automated Battery Monitoring Systems (ABMS).
According to the company, the ABMS is capable of collecting, processing, displaying, and communicating battery data for both sealed and flooded battery types.
The system is designed to support modern submarine batteries by enabling continuous remote health monitoring.
L3Harris Maritime, Space & Mission Systems president Nino DiCosmo said: “These systems directly impact operational capability and crew safety.
“This contract reflects our commitment to delivering reliable solutions that support two of the service’s highest-priority submarine platforms that serve as the backbone of America’s strategic deterrence.”
The agreement extends L3Harris’ ongoing relationship with the US Navy submarine force, with its battery and communications systems already in use on legacy platforms including Ohio– and Los Angeles-class submarines, as well as the more advanced Virginia-class.
L3Harris is also a key supplier for the Columbia-class ballistic missile submarine programme, which is set to replace the Navy’s current nuclear deterrence fleet.
Earlier this year, L3Harris secured what it described as its largest full-rate production contract for communications equipment with General Dynamics Electric Boat, covering 26 shipsets for both the Virginia– and Columbia-class submarines.
The most recent award provides for production through 2033, with provisions for support to future Columbia-class vessels and allied navies.
