Turbo-electric transmission

For turbo-electric transmissions driven by gas turbines, see Turbine-electric transmission.

The battleship USS New Mexico, launched in 1917, was the World's first turbo-electric steamship.

Turbo-electric transmission uses electric generators to convert the mechanical energy of a turbine (steam or gas) into electric energy and electric motors to convert it back into mechanical energy to power the driveshafts.

Turbo-electric drives are used in some rail locomotives (gas turbines, e.g. with the first TGV) and ships (steam and more recently gas turbines). An advantage of turbo-electric transmission is that it allows the adaptation of high-speed turning turbines to the slowly turning propellers or wheels without the need of a heavy and complex gearbox. It also has the advantage of being able to provide electricity for the ship or train's other electrical systems, such as lighting, computers, radar, and communications equipment.
