turbo-electric propulsion

By 1931 she had been converted from diesel-electric to steam turbo-electric propulsion.

The ship's turbo-electric propulsion system allowed her to supplement the electrical supply of Tacoma, Washington, during a drought in late 1929 to early 1930.

Some nuclear submarines also decouple their reactor room this way, having turbo-electric propulsion driven by reactor steam.

The DET's substitution for a turbo-electric propulsion plant was the primary difference with the predecessor Buckley ("TE") class.

Turbo-electric propulsion was selected for the battlecruisers despite the fact it needed more room than geared turbines to allow for better underwater protection that wartime experience showed was essential.

The Sun Shipbuilding and Drydock Company of Chester, Pennsylvania worked around this problem by designing a T2 variant which used turbo-electric propulsion; that is, the steam turbine ran a generator, which in turn powered electric drive motors without the need for gearing.

A comparison of the turbo-electric propulsion with the more conventional direct-drive turbine design used on her sister ships showed that the conventional design generated 2.5x the power per ton of machinery and required 1/3 the floor area although at the cost of 20% greater fuel consumption, always a concern for the US Navy given Pacific distances.
