I was just wondering with the new CGX and DDX being electric, and I also think the intergrated power system is good to. I think it depends on how the DDX and CGX do once they come in to the fleet.

Yeah I think electric power systems are the future for almost all naval vessels. The advantages in acoustic signature, flexibility, and maintainability make their eventual adoption almost certain. With the onset of railguns and energy weapons on board naval vessels, it will become a requirement rather than a luxury.
The frigates are powered by a diesel-electric and gas (CODLAG) system, which consists of two Rolls Royce Spey SM1A 34000 hp gas turbines and two Alstom1.5 MW 4400 hp electric motors. There are also four Alstom 12 RP2000CZ 1.3 MW 7000 hp auxiliary diesels. Using the diesel-electric motors, the economical speed is 15 knots and the range is 7,800 miles. Maximum speed is 28 knots.

As far as acoustics on a aircraft carrier...this issue is a moot point ...when a catapult launchs ..down the track..with a screaming roaring jet strapped to it ..quietness becomes useless. Same thing with recovering airplanes...it is anything but a quiet evolution.
