L3Harris supplies power systems for U.S. Navy’s Virginia- and Columbia-class submarines

L3Harris Technologies is extending its submarine power-system work to the Navy's Columbia-class ballistic missile submarines after supplying power distribution systems and universal modular masts throughout the Virginia-class fleet. Its electrical portfolio includes switchgear, protection equipment and high-density power conversion systems that support sensors, weapons and crew services during extended submerged operations. The equipment is engineered and tested for shock resistance, electromagnetic compatibility, thermal performance and long-term reliability under submarine operating conditions. The October 22 company statement described continuing program support and investment in future naval power technologies, without announcing a new contract value or a detailed Columbia delivery schedule.
