GA-EMS to Design Large Displacement UUV Motor & Power System

By Phoebe Grinter / 07 Sep 2021

General Atomics Electromagnetic Systems (GA-EMS) has been awarded a design contract from the U.S. Navy Office of Naval Research (ONR) to develop a concept for integrating a GA-EMS motor and next generation power system into a Large Displacement Unmanned Underwater Vehicle (LDUUV) to provide power for propulsion and an energy storage system.


“Our energy and battery systems have been successfully demonstrated and proven safe for use on a variety of underwater manned and unmanned vehicles,” stated Scott Forney, president of GA-EMS. 

“Over the course of the last two years, the motor has undergone lab testing, and power system has completed underwater testing. Both systems have performed successfully, demonstrating capabilities to both power and propel underwater vehicles. 

“Together, the systems are proving to be key technologies to provide the combined power, energy density, and improved vehicle performance necessary to help meet the objectives.”

Development and testing of both motor and power systems continues in order to optimize performance. An LDUUV with the integrated motor and power propulsion system will undergo at-sea testing at a later stage of the program.
