Some of the Navy’s most advanced high-tech ships are being supplied energy by equally advanced power plants. Some of those ships sport state-of-the-art electric propulsion systems and stealth design among their innovative features. The ships use gas turbines to produce electricity that is then used to power electric motors for propulsion, explains Fulton Schools Professor Brad Allenby. The electricity generated can also be used to power weapons systems, he adds. Allenby is the author of the book “Future Conflict & Emerging Technologies,” and editor of “The Applied Ethics of Military and Security Technologies.” He is a former Stockdale Fellow at the U.S Naval Academy and an associate faculty member with ASU’s Center for the Future of War.
