Electric drive gives many advantages but one of the major advantages is 100% torque at 1 to max RPM (not totally correct but theoretically possible) but way better than ICE can ever do. Thus the interests in electric propulsion are motivated by efficiency, flexibility, optimization driven engineering and operating concerns not just toy of the month....... |
Yo my knowledge the only vessels using electric drive currently are the 3 Zumwalt destroyers which are not diesel electric but gas turbine electric powered.
The next class of destroyers/cruisers are gas turbine driven thru reduction gears.
The 2 littoral
classes are driven combined gas & diesel
water jets that have problems with the mechanical
transmission.
Nimitz & Ford aircraft carriers are steam turbine driven thru reduction gears.
