Future defense systems, such as free-electron laser directed-energy weapons, dynamic armor, and tracking systems will require more power. "Only half of the electrical power-generation capability on CVN-78 is needed to run currently planned systems, including EMALS. CVN-78 will thus have the power reserves that the "Nimitz" class lacks to run lasers and dynamic armor." The addition of new technologies, power systems, design layout, and better control systems results in an increased sortie rate of 25% over the "Nimitz" class and a 25% reduction in manpower required to operate.
