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.

Ships with turbo-electric drive[edit]

USS Langley, the US Navy's first aircraft carrier, was converted to turbo-electric transmission in 1920–22.
USS Tullibee, launched in 1960, was the US Navy's first turbo-electric submarine.

Uruguay. She was launched in 1927 as California, the World's first turbo-electric ocean liner.
Normandie, launched in 1932, was the World's most powerful turbo-electric steamship.
Canberra, launched in 1960, was the first ship with alternating current (AC) turbo-electric transmission.
