Leonardo DRS reaches new milestone for the first US Columbia class submarine

According to a PR published by Leonardo DRS on August 30, 2022, the firm announced that it has successfully completed factory acceptance testing and shipment of the first production unit of the main propulsion motor for the U.S. Navy’s new Columbia class submarine. The motor was recently shipped to General Dynamics Electric Boat (EB) for integration into the lead ship of the class. [...]

DRS was chosen by EB and the U.S. Navy to design and manufacture the major Columbia Electric Drive Propulsion system components including the main propulsion electric motor.

All prototype components of this system successfully completed full power endurance and other testing at the Navy’s land-based test facility in 2020, where operational testing continues. In addition to the main propulsion motor, other lead ship components are being manufactured and are also preparing to ship to Electric Boat. The Columbia class program goal is to design and build a class of 12 new ballistic missile submarines (SSBNs) to replace the U.S. Navy’s current force of Ohio class SSBNs.
