The use of electric power for marine propulsion, particularly in modern Navy surface ship designs such as large Hydrofoils, Surface Effect Ships, SWATH ships and gas turbine powered displacement hulls is reviewed. The unconventional geometries of several of these ships require the transmission of 15,000 to 30,000 kW through several right angles and down long struts. Gas turbine powered ships can realize significant fuel economy through the flexibility of electric drive as opposed to the fixed ratio of a mechanical gear drive. A review of the possible candidate electric drive systems shows that homopolar machinery, and particularly superconducting machinery, is well suited to the requirements for lightweight, compact, high efficiency power transmission. The current status of development of this machinery is reviewed and some trends for the future discussed.
