General Atomics Awarded ONR Contract for LDUUV Motor and Energy Storage System

General Atomics Electromagnetic Systems (GA-EMS) announced today that it has been awarded a design contract from the Office of Naval Research (ONR) to develop a concept for integrating a unique GA-EMS motor and next generation power system into a Large Displacement Unmanned Underwater Vehicle (LDUUV). The planned systems will provide the LDUUV with power for propulsion and an energy storage system to support improved system performance necessary for future LDUUV operations. 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 eventually will undergo at-sea testing during a later phase of the program.

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

The U.S. Naval Sea Systems Command (NAVSEA) Program Executive Office Unmanned and Small Combatants’ Large Displacement Unmanned Undersea Vehicle (LDUUV) program is also known as Snakehead. Snakehead is a long-endurance, multi-mission UUV, deployed from submarine large open interfaces, with the capability to deploy reconfigurable payloads. It is the largest UUV intended for hosting and deployment from submarines, and has been designated a Maritime Accelerated Acquisition. The LDUUV will achieve full integration with Modernized Dry Deck Shelter and Payload Handling System-equipped submarines.

General Atomics Electromagnetic Systems (GA-EMS) Group is a global leader in the research, design, and manufacture of first-of-a- kind electromagnetic and electric power generation systems. GA-EMS’ history of research, development, and technology innovation has led to an expanding portfolio of specialized products and integrated system solutions supporting aviation, space systems and satellites, missile defense, power and energy, and processing and monitoring applications for critical defense, industrial, and commercial customers worldwide.
