New Battery Technology for Mini-Submarines

Northrop Grumman has been awarded a $4 million contract by the U.S. Naval Sea Systems Command (NAVSEA) for the development and integration of lithium-ion battery technology for the U.S. Special Operations Force's new Advanced SEAL Delivery System (ASDS). The ASDS is designed and built by Northrop Grumman's Oceanic & Naval Systems business unit. It is a mini-submarine intended to clandestinely carry Navy SEAL teams and their combat gear to and from hostile shores. This first-of-its-kind system is transported to a mission area atop an attack-class nuclear submarine, or it can be airlifted for deployment to littoral theaters worldwide.

"The emerging lithium-ion battery technology promises a 20- to 40-times improvement in life cycle and reduced operational cost when compared with traditional battery technologies," said Bruce Ballantyne, director of Special Defense and Submersible Programs for Northrop Grumman. "This technology enables the Navy to expand the types of missions the ASDS can perform." Northrop Grumman's Oceanic and Naval Systems, a business unit of the company's Electronic Systems sector, designs, produces, tests and supports some of the world's most sophisticated undersea systems.
